# Volume Normalization Modal - Design Document
## Overview
The Volume Normalization Modal is a PyQt6 dialog component that enables users to configure audio loudness normalization settings before downloading tracks. The feature integrates with the existing Download tab and provides both preset configurations and custom parameter tuning. Settings persist globally across application sessions, ensuring consistent audio processing behavior.
### Key Design Goals
1. **User-Friendly Configuration**: Provide preset options for non-technical users while allowing advanced customization
2. **Persistent Settings**: Store user preferences to avoid reconfiguration across sessions
3. **Seamless Integration**: Integrate with existing downloader and config modules without breaking changes
4. **Validation and Safety**: Ensure all parameters conform to FFmpeg loudnorm specifications
5. **Consistent UI/UX**: Match existing modal styling and application design patterns
---
## Architecture
### System Context
The Volume Normalization Modal operates within a three-layer architecture:
```
┌─────────────────────────────────────────────────────────────┐
│ UI Layer (PyQt6) │
│ ┌──────────────────────────────────────────────────────┐ │
│ │ DownloadTab │ │
│ │ ├─ Normalization Settings Button │ │
│ │ └─ Preset Indicator │ │
│ │ │ │
│ │ NormalizationModal (Dialog) │ │
│ │ ├─ Preset Selection (Radio Buttons) │ │
│ │ ├─ Parameter Input Fields (I, TP, LRA) │ │
│ │ ├─ Validation & Error Display │ │
│ │ └─ Apply/Cancel Buttons │ │
│ └──────────────────────────────────────────────────────┘ │
└─────────────────────────────────────────────────────────────┘
↓
┌─────────────────────────────────────────────────────────────┐
│ Config Layer (Persistence) │
│ ┌──────────────────────────────────────────────────────┐ │
│ │ Config Module (src/core/config.py) │ │
│ │ ├─ Normalization Settings Storage │ │
│ │ ├─ Preset Definitions │ │
│ │ └─ Default Configuration │ │
│ └──────────────────────────────────────────────────────┘ │
└─────────────────────────────────────────────────────────────┘
↓
┌─────────────────────────────────────────────────────────────┐
│ Core Layer (Processing) │
│ ┌──────────────────────────────────────────────────────┐ │
│ │ YouTubeDownloader (src/core/downloader.py) │ │
│ │ ├─ normalize_volume() - Uses Config settings │ │
│ │ ├─ Parameter Validation │ │
│ │ └─ FFmpeg Command Construction │ │
│ └──────────────────────────────────────────────────────┘ │
└─────────────────────────────────────────────────────────────┘
```
### Data Flow
1. **Initialization**: Application starts → Config loads saved settings → Modal displays current preset
2. **User Interaction**: User selects preset/custom params → Modal validates → User clicks Apply
3. **Persistence**: Modal saves settings to Config → Config persists to storage
4. **Download**: Download initiated → Downloader reads settings from Config → FFmpeg applies normalization
---
## Components and Interfaces
### 1. NormalizationModal Class
**File**: `src/ui/components/normalization_modal_qt.py`
**Responsibilities**:
- Display preset selection interface
- Manage custom parameter input fields
- Validate user input against FFmpeg specifications
- Handle apply/cancel operations
- Load and display current settings
**Key Methods**:
```python
class NormalizationModal(QDialog):
"""Modal dialog for configuring volume normalization settings."""
settings_applied = pyqtSignal(dict) # Emitted when Apply is clicked
def __init__(self, parent, config):
"""Initialize modal with current settings from config."""
def _load_current_settings(self):
"""Load saved settings from Config module."""
def _on_preset_selected(self, preset_name: str):
"""Handle preset selection - update fields and enable/disable editing."""
def _on_parameter_changed(self, param_name: str, value: str):
"""Handle parameter input changes - validate and update UI."""
def _validate_parameters(self) -> tuple[bool, str]:
"""Validate all parameters against FFmpeg specifications."""
def _update_parameter_fields(self, params: dict):
"""Update input fields with parameter values."""
def _enable_custom_editing(self, enabled: bool):
"""Enable/disable custom parameter input fields."""
def _on_apply(self):
"""Save settings and close modal."""
def _on_cancel(self):
"""Close modal without saving."""
def get_current_settings(self) -> dict:
"""Return current settings as dict."""
```
**Signals**:
- `settings_applied(dict)`: Emitted when Apply is clicked with new settings
### 2. DownloadTab Integration
**File**: `src/ui/tabs/download_tab_qt.py` (modifications)
**Changes**:
- Add "Normalization Settings" button to control panel
- Add preset indicator label showing current active preset
- Connect button to open NormalizationModal
- Display tooltip with current parameters on hover
**New Methods**:
```python
def _open_normalization_modal(self):
"""Open the normalization settings modal."""
def _update_preset_indicator(self, preset_name: str):
"""Update the preset indicator label."""
def _on_normalization_settings_applied(self, settings: dict):
"""Handle settings applied from modal."""
```
### 3. Config Module Extensions
**File**: `src/core/config.py` (modifications)
**New Class**: `NormalizationSettings`
```python
class NormalizationSettings:
"""Manages normalization settings persistence."""
# Preset definitions
PRESETS = {
'Quiet': {'I': -18, 'TP': -1.5, 'LRA': 11},
'Normal': {'I': -14, 'TP': -1.5, 'LRA': 11},
'Loud': {'I': -10, 'TP': -1.5, 'LRA': 11},
'Very Loud': {'I': -6, 'TP': -1.5, 'LRA': 11},
}
# Parameter validation ranges
PARAM_RANGES = {
'I': (-23, 0), # Integrated Loudness (LUFS)
'TP': (-5, 0), # True Peak (dBFS)
'LRA': (1, 20), # Loudness Range (LU)
}
@classmethod
def load_settings(cls) -> dict:
"""Load normalization settings from storage."""
@classmethod
def save_settings(cls, preset: str, custom_params: dict = None) -> bool:
"""Save normalization settings to storage."""
@classmethod
def get_default_settings(cls) -> dict:
"""Return default settings (Normal preset)."""
@classmethod
def validate_parameters(cls, params: dict) -> tuple[bool, str]:
"""Validate parameters against ranges."""
@classmethod
def get_preset_params(cls, preset_name: str) -> dict:
"""Get parameters for a preset."""
```
**Storage Format** (JSON in config file):
```json
{
"normalization": {
"current_preset": "Normal",
"custom_parameters": {
"I": -14,
"TP": -1.5,
"LRA": 11
}
}
}
```
### 4. Downloader Module Integration
**File**: `src/core/downloader.py` (modifications)
**Changes to `normalize_volume` method**:
```python
def normalize_volume(self, filepath: str, timeout: int = 60) -> bool:
"""Normalize audio loudness using configured settings."""
if not self.ffmpeg:
return True
# Load current settings from Config
settings = NormalizationSettings.load_settings()
params = settings.get('custom_parameters', {})
# Validate parameters
valid, error_msg = NormalizationSettings.validate_parameters(params)
if not valid:
logger.error(f"Invalid normalization parameters: {error_msg}")
return False
# Construct FFmpeg filter string
filter_str = f"loudnorm=I={params['I']}:TP={params['TP']}:LRA={params['LRA']}"
# ... rest of implementation
```
---
## Data Models
### Normalization Settings Structure
```python
{
"current_preset": str, # "Quiet", "Normal", "Loud", "Very Loud", or "Custom"
"custom_parameters": {
"I": float, # Integrated Loudness (-23 to 0 LUFS)
"TP": float, # True Peak (-5 to 0 dBFS)
"LRA": float, # Loudness Range (1 to 20 LU)
}
}
```
### Preset Definitions
```python
PRESETS = {
"Quiet": {
"I": -18,
"TP": -1.5,
"LRA": 11,
"description": "For content that should remain quiet"
},
"Normal": {
"I": -14,
"TP": -1.5,
"LRA": 11,
"description": "Default, suitable for most music"
},
"Loud": {
"I": -10,
"TP": -1.5,
"LRA": 11,
"description": "For content that should be louder"
},
"Very Loud": {
"I": -6,
"TP": -1.5,
"LRA": 11,
"description": "For maximum loudness"
}
}
```
### Parameter Validation Ranges
```python
PARAM_RANGES = {
"I": {
"min": -23,
"max": 0,
"unit": "LUFS",
"description": "Integrated Loudness"
},
"TP": {
"min": -5,
"max": 0,
"unit": "dBFS",
"description": "True Peak"
},
"LRA": {
"min": 1,
"max": 20,
"unit": "LU",
"description": "Loudness Range"
}
}
```

### Settings Loading
1. **Application Startup**:
- Config module loads settings from storage
- If missing/corrupted, use defaults
- Log warning if loading fails
2. **Modal Open**:
- Load current settings from Config
- Display current preset as selected
- Populate parameter fields
- Enable/disable custom fields based on preset
3. **Download Initiation**:
- Downloader reads settings from Config
- Validate parameters before use
- Log parameters being applied
### Settings Saving
1. **Apply Button Clicked**:
- Validate all parameters
- If invalid, show error and don't save
- If valid, save to Config
- Emit signal with new settings
- Close modal
2. **Config Save**:
- Write to persistent storage
- Log success/failure
- Notify UI of changes
---
## Integration Points
### 1. DownloadTab ↔ NormalizationModal
**Connection**:
```python
# In DownloadTab.__init__
self.normalization_modal = NormalizationModal(self, self.config)
self.normalization_modal.settings_applied.connect(self._on_normalization_settings_applied)
self.normalization_btn.clicked.connect(self._open_normalization_modal)
```
**Data Flow**:
- DownloadTab passes Config instance to modal
- Modal emits `settings_applied` signal when Apply clicked
- DownloadTab updates preset indicator
### 2. NormalizationModal ↔ Config
**Connection**:
```python
# In NormalizationModal
settings = NormalizationSettings.load_settings()
NormalizationSettings.save_settings(preset, custom_params)
```
**Data Flow**:
- Modal reads current settings on open
- Modal saves settings on Apply
- Config handles persistence
### 3. Downloader ↔ Config
**Connection**:
```python
# In YouTubeDownloader.normalize_volume
settings = NormalizationSettings.load_settings()
params = settings['custom_parameters']
```
**Data Flow**:
- Downloader reads settings before normalization
- Downloader validates parameters
- Downloader constructs FFmpeg command with parameters
### 4. Backward Compatibility
**Existing Code**:
- Current `normalize_volume` uses hardcoded: `loudnorm=I=-14:TP=-1.5:LRA=11`
- This matches the "Normal" preset
**Migration**:
- If no settings exist, default to "Normal" preset
- Existing behavior preserved
- No breaking changes to API

## Correctness Properties
*A property is a characteristic or behavior that should hold true across all valid executions of a system—essentially, a formal statement about what the system should do. Properties serve as the bridge between human-readable specifications and machine-verifiable correctness guarantees.*
### Property 1: Preset Selection Updates Parameters
*For any* preset selection (Quiet, Normal, Loud, Very Loud), selecting that preset shall update the parameter input fields to display the correct values for that preset.
**Validates: Requirements 2.3**
### Property 2: Non-Custom Presets Disable Editing
*For any* non-Custom preset selection, the parameter input fields shall be disabled (read-only) and cannot be edited by the user.
**Validates: Requirements 2.4**
### Property 3: Custom Preset Enables Editing
*When* the Custom preset is selected, the parameter input fields shall be enabled and editable by the user.
**Validates: Requirements 2.5**
### Property 4: Modal Loads Current Settings
*For any* application state with saved normalization settings, opening the NormalizationModal shall display the currently active preset as pre-selected.
**Validates: Requirements 2.6**
### Property 5: Parameter Validation Enforces Ranges
*For any* parameter value entered in a custom parameter field, if the value is outside the allowed range (I: -23 to 0, TP: -5 to 0, LRA: 1 to 20), an error message shall be displayed and the Apply button shall remain disabled.
**Validates: Requirements 3.3, 3.4, 8.2, 8.3**
### Property 6: Cancel Discards Changes
*For any* changes made in the NormalizationModal, clicking Cancel shall close the modal without saving any changes, and the previous settings shall remain active.
**Validates: Requirements 1.9**
### Property 7: Apply Saves Settings
*For any* valid parameter configuration in the NormalizationModal, clicking Apply shall save the settings to persistent storage and close the modal.
**Validates: Requirements 1.10, 4.1**
### Property 8: Settings Persist Across Sessions
*For any* normalization settings saved via Apply, when the application is restarted, the NormalizationModal shall load and display the previously saved settings.
**Validates: Requirements 4.3**
### Property 9: Downloader Uses Configured Settings
*For any* download initiated after normalization settings are configured, the Downloader shall use the current settings from Config to construct the FFmpeg loudnorm filter string.
**Validates: Requirements 5.1, 5.2, 5.3**
### Property 10: Settings Button Always Enabled
*For any* application state (downloads running or idle), the "Normalization Settings" button in the Download tab shall be enabled and clickable.
**Validates: Requirements 6.4**
### Property 11: Modal Opens on Button Click
*When* the user clicks the "Normalization Settings" button in the Download tab, the NormalizationModal shall open and display the current settings.
**Validates: Requirements 6.3**
### Property 12: Preset Indicator Shows Current Preset
*For any* active normalization preset, the Download tab shall display an indicator showing the current preset name.
**Validates: Requirements 7.4**
### Property 13: Default Settings on First Run
*When* the application starts for the first time with no saved normalization settings, the NormalizationModal shall display the "Normal" preset as selected with parameters I=-14, TP=-1.5, LRA=11.
**Validates: Requirements 4.5, 12.1, 12.2**
### Property 14: All Presets Valid
*For all* preset definitions (Quiet, Normal, Loud, Very Loud), all parameters shall conform to FFmpeg loudnorm specifications: I between -23 and 0, TP between -5 and 0, LRA between 1 and 20.
**Validates: Requirements 10.1, 10.2, 10.3, 10.4**
### Property 15: Configuration Structure Correct
*For any* saved normalization settings, the stored configuration shall include the keys: `current_preset` (string) and `custom_parameters` (dict with I, TP, LRA keys).
**Validates: Requirements 11.2**
### Property 16: Invalid Parameters Prevent Apply
*For any* invalid parameter value (non-numeric or out of range), the Apply button shall remain disabled until all parameters are corrected to valid values.
**Validates: Requirements 8.1, 8.3, 8.4**
### Property 17: Downloader Validates Before Processing
*When* the Downloader receives normalization parameters, the parameters shall be validated against the allowed ranges before constructing the FFmpeg command.
**Validates: Requirements 10.5**
### Property 18: Failed Normalization Doesn't Stop Download
*If* normalization fails during audio processing, the download process shall continue and the file shall be saved without normalization applied.
**Validates: Requirements 5.5**
### Property 19: Modal Changes Don't Affect Running Downloads
*When* the NormalizationModal is open and the user changes settings, any currently running downloads shall continue using the previously configured settings until the next download is initiated.
**Validates: Requirements 6.6**
### Property 20: Corrupted Config Uses Defaults
*If* the configuration file is corrupted or missing, the application shall use the default "Normal" preset settings and log a warning.
**Validates: Requirements 11.5, 12.4**

## Error Handling
### Input Validation Errors
| Error Condition | Message | Action |
|---|---|---|
| Non-numeric input | "Parameter must be a number" | Show error, disable Apply |
| Value < minimum | "Parameter {name} must be between {min} and {max}" | Show error, disable Apply |
| Value > maximum | "Parameter {name} must be between {min} and {max}" | Show error, disable Apply |
| Empty field | "Parameter {name} is required" | Show error, disable Apply |
### Configuration Errors
| Error Condition | Message | Action |
|---|---|---|
| Config file missing | Log warning, use defaults | Application continues |
| Config file corrupted | Log warning, use defaults | Application continues |
| Save failure | "Failed to save settings. Please try again." | Show error in modal |
| Load failure | Log warning, use defaults | Application continues |
### FFmpeg Errors
| Error Condition | Action |
|---|---|
| Invalid parameters | Log error, skip normalization |
| FFmpeg timeout | Log error, skip normalization |
| FFmpeg not found | Log error, skip normalization |
| File processing error | Log error, skip normalization |
### Recovery Strategies
1. **Validation Failure**: User corrects input, error clears, Apply becomes enabled
2. **Save Failure**: User clicks Apply again, or closes and reopens modal
3. **Load Failure**: Application uses defaults, user can reconfigure
4. **FFmpeg Failure**: Download continues without normalization, user can retry
---

1. Check if normalization settings exist
2. If not, create with default "Normal" preset
3. Log migration event
4. No user action required
### Backward Compatibility
- Existing `normalize_volume` behavior preserved
- Default settings match current hardcoded values
- No breaking changes to public APIs
- Graceful degradation if settings unavailable
### Performance Impact
- Minimal: Settings loaded once at startup
- Settings lookup is O(1) dictionary access
- No additional FFmpeg overhead
- No UI performance impact
---
## Future Enhancements
1. **Preset Management**: Allow users to create and save custom presets
2. **Per-Track Settings**: Apply different settings to different tracks
3. **Batch Operations**: Apply settings to multiple files
4. **Settings Export/Import**: Share settings between users
5. **Advanced Visualization**: Show loudness graphs and analysis
6. **A/B Comparison**: Compare before/after audio samples

## Introduction
The dl_yt application currently applies volume normalization to downloaded audio files using FFmpeg's loudnorm filter with fixed parameters (I=-14:TP=-1.5:LRA=11). Users have reported that the default normalization level is too low, resulting in audio that requires manual volume adjustment. This feature introduces a modal dialog in the Download tab that allows users to configure volume normalization settings before initiating downloads. The modal provides preset options and custom parameter configuration, with settings persisted globally for future sessions.
## Glossary
- **Volume_Normalization**: The process of adjusting audio loudness to a consistent level using FFmpeg's loudnorm filter
- **Loudnorm_Filter**: FFmpeg audio filter that normalizes loudness according to ITU-R BS.1770 standard
- **Integrated_Loudness**: The overall loudness of an audio file measured in LUFS (Loudness Units relative to Full Scale), controlled by the 'I' parameter
- **True_Peak**: The maximum instantaneous peak level in the audio, controlled by the 'TP' parameter
- **Loudness_Range**: The range between the quietest and loudest parts of the audio, controlled by the 'LRA' parameter
- **Download_Tab**: The PyQt6 UI component that manages playlist downloads and audio processing
- **Normalization_Modal**: A dialog window that allows users to configure volume normalization settings
- **Global_Settings**: Configuration values persisted to disk that apply to all future downloads until changed
- **Per_Download_Settings**: Configuration values that apply only to the current download session
- **Preset**: A predefined set of normalization parameters with a descriptive name
- **Custom_Parameters**: User-defined normalization values that override preset settings
- **Config_Module**: The centralized configuration management system (src/core/config.py)
- **Downloader_Module**: The core module that handles audio processing including volume normalization (src/core/downloader.py)
## Requirements
### Requirement 1: Modal Dialog Appearance and Accessibility
**User Story:** As a user, I want a clear and intuitive modal dialog to configure volume normalization settings, so that I can easily adjust audio loudness before downloading.

9. WHEN the user clicks "Cancel", THE Normalization_Modal SHALL close without applying changes
10. WHEN the user clicks "Apply", THE Normalization_Modal SHALL save settings and close
### Requirement 2: Preset Selection Interface
**User Story:** As a user, I want to select from predefined normalization presets, so that I can quickly choose appropriate settings without understanding technical parameters.
#### Acceptance Criteria
1. THE Normalization_Modal SHALL display a "Presets" section with radio buttons for preset selection
2. THE Normalization_Modal SHALL provide the following presets:
- "Quiet" (I=-18, TP=-1.5, LRA=11) - for content that should remain quiet
- "Normal" (I=-14, TP=-1.5, LRA=11) - the current default, suitable for most music
- "Loud" (I=-10, TP=-1.5, LRA=11) - for content that should be louder
- "Very Loud" (I=-6, TP=-1.5, LRA=11) - for maximum loudness
- "Custom" - allows user-defined parameters
3. WHEN a preset is selected, THE Normalization_Modal SHALL update the parameter input fields to display the preset values
4. WHEN a preset is selected, THE Normalization_Modal SHALL disable the parameter input fields (make them read-only)
5. WHEN the "Custom" preset is selected, THE Normalization_Modal SHALL enable the parameter input fields for editing
6. THE Normalization_Modal SHALL display the currently active preset as pre-selected when the modal opens
### Requirement 3: Custom Parameter Configuration

4. IF a parameter value is outside the allowed range, THE Normalization_Modal SHALL display an error message and prevent applying settings
5. THE Normalization_Modal SHALL display the current custom parameter values when opened
6. WHEN a preset is selected (other than "Custom"), THE parameter input fields SHALL update to show preset values but remain read-only
### Requirement 4: Global Settings Persistence
**User Story:** As a user, I want my normalization settings to persist across application sessions, so that I don't need to reconfigure them each time I use the application.
#### Acceptance Criteria
1. WHEN the user clicks "Apply" in the Normalization_Modal, THE selected preset and custom parameters SHALL be saved to persistent storage

6. THE settings storage location SHALL be documented in code comments
### Requirement 5: Settings Application to Downloads
**User Story:** As a user, I want the configured normalization settings to be applied to all downloaded audio files, so that my audio has consistent loudness.
#### Acceptance Criteria

# YouTube Bot Detection Improvements - Summary
## Changes Made
### 1. Enhanced HTTP Headers (src/core/downloader.py)
- Updated User-Agent to Chrome 120 (more recent)
- Added more realistic HTTP headers:
- `Accept`: Full HTML/XML/WebP support
- `Accept-Encoding`: gzip, deflate
- `DNT`: 1 (Do Not Track)
- `Connection`: keep-alive
- `Upgrade-Insecure-Requests`: 1
### 2. Cookie Support
- Added automatic detection of `cookies.txt` file
- If cookies exist, they're automatically used for all requests
- Cookies provide authenticated session, much more reliable than User-Agent spoofing
### 3. Improved Retry Logic
- **Search phase**: Exponential backoff with longer delays for bot detection
- 4s → 8s → 16s → 32s → 64s
- Distinguishes between bot detection and other errors
- **Download phase**: Separate retry logic with 3 attempts
- 4s → 8s → 16s delays
- Handles format unavailability gracefully
### 4. Better Error Handling
- Distinguishes between different error types:
- Bot detection errors: Longer delays, more retries
- Format unavailable: No retry (video doesn't have audio)
- Other errors: Standard retry logic
- Cleaner error messages
### 5. Cookie Export Tools
- **export_youtube_cookies.py**: Improved with better instructions
- **YOUTUBE_BOT_DETECTION.md**: New troubleshooting guide
## How to Use Cookies
### Quick Start
1. Make sure you're logged in to YouTube in your browser
2. Run: `python export_youtube_cookies.py`
3. Done! The app will use cookies automatically
### Alternative (yt-dlp method)
```bash
yt-dlp --cookies-from-browser firefox -o /dev/null https://www.youtube.com
```
## What Changed in Code
### src/core/downloader.py
**_get_ydl_options():**
- Added cookie file detection
- Enhanced HTTP headers
- Updated User-Agent to Chrome 120
**download_best_match():**
- Longer delays for bot detection (4s, 8s, 16s, 32s, 64s)
- Better error classification
**_download_url():**
- Added retry logic for downloads
- Handles bot detection during download phase
- Distinguishes format errors from other errors
## Testing
The improvements have been tested with:
- ✅ Enhanced HTTP headers
- ✅ Cookie support (if available)
- ✅ Exponential backoff for bot detection
- ✅ Better error messages
## Backward Compatibility
- ✅ Works without cookies (uses User-Agent spoofing)
- ✅ Automatically uses cookies if available
- ✅ No breaking changes to existing code
- ✅ All existing features still work
## Next Steps
If you still get bot detection errors:
1. Try exporting cookies: `python export_youtube_cookies.py`
2. Wait a few hours (YouTube may have temporarily blocked your IP)
3. Try a different browser for cookie export
4. Consider using a VPN (if allowed in your region)

# Extraction Playlist Spotify
Ce projet extrait les informations d'une playlist Spotify à partir d'un HTML donné, utilise BeautifulSoup pour parser le HTML, et sauvegarde les données extraites dans un fichier JSON.
## Utilisation
1. Placez le HTML de la playlist dans la variable `html_content` du script.
2. Exécutez le script principal.
3. Le fichier `playlist_rock_metal.json` sera généré.
## Dépendances
