Ddsp Vocoder

output_audio = model(features, use_conditional_norm=False)

| Component | Parameters | |-----------|-------------| | | F0, amplitudes per harmonic (up to 100 partials) | | Filtered noise | Loudness + frequency‑shaped noise (via learned filter) | | Transient / impact | Learned click + exponential decay for percussive attacks | | Reverb tail | Small learned convolution (room impulse response) | ddsp vocoder

By combining these, the vocoder captures both the tonal stability and the organic imperfections that make audio sound "real." Conclusion output_audio = model(features

You don't need to train from scratch. Google provides a pre-trained "solo violin" and "singer" model.
