## Validation Checklist

### 1. Data Pipeline Validation
- **Audio Format Consistency**: Check sample rates, bit depths, and channel configurations
- **Preprocessing Chain**: Validate audio normalisation, windowing, and feature extraction
- **Data Augmentation**: Review pitch shifting, time stretching, and noise injection parameters
- **Dataset Balance**: Assess class distribution and duration balance across training data
- **Quality Control**: Verify audio quality filtering and silence detection

### 2. Model Architecture Validation
- **Input Specifications**: Check audio input dimensions match model expectations
- **Architecture Compatibility**: Validate base model supports target audio tasks
- **Memory Requirements**: Assess GPU memory needs for batch sizes and sequence lengths
- **Gradient Flow**: Check for vanishing/exploding gradients in audio-specific layers
- **Output Alignment**: Verify output format matches downstream requirements

### 3. Training Process Validation
- **Learning Rate Scheduling**: Review warmup, decay, and adaptive learning strategies
- **Batch Composition**: Validate mixed-duration batching and padding strategies
- **Checkpoint Strategy**: Check model saving frequency and validation metrics
- **Monitoring Setup**: Verify audio quality metrics and training loss tracking
- **Resource Management**: Assess training time estimates and compute requirements

### 4. Evaluation and Testing
- **Audio Quality Metrics**: Check PESQ, STOI, MOS, or task-specific measures
- **Latency Testing**: Validate real-time processing requirements
- **Robustness Testing**: Test with background noise, compression artifacts
- **Edge Case Handling**: Verify behaviour with silence, clipping, or unusual inputs
- **Deployment Compatibility**: Check inference format and serving requirements

### 5. Production Readiness
- **Model Quantisation**: Validate INT8/FP16 conversion impacts on audio quality
- **Streaming Support**: Check real-time audio processing capabilities
- **Error Handling**: Test graceful degradation with corrupted audio inputs
- **Performance Monitoring**: Verify audio quality tracking in production
- **Rollback Strategy**: Check model versioning and deployment rollback plans

## Output Format
For each validation area:
1. **Assessment**: Pass/Fail/Needs Review
2. **Critical Issues**: Problems that block production deployment
3. **Performance Concerns**: Issues affecting audio quality or speed
4. **Best Practice Recommendations**: Improvements aligned with audio AI standards
5. **Test Scenarios**: Specific cases to validate before deployment

Focus on audio-specific validation that standard ML pipelines might miss.
