PitchFlower: Flow-Based Neural Audio Codec With Pitch Controllability
Researchers introduce PitchFlower, a flow-based neural audio codec designed to separate pitch information from other audio content. The method applies a training perturbation in which F0 contours are flattened and randomly shifted, encouraging the model to disentangle pitch from the rest of the signal. This yields explicit, adjustable pitch control when synthesizing or compressing audio.
