PitchFlower audio codec offers precise pitch control with high quality

Researchers have introduced PitchFlower, a novel flow-based neural audio codec designed for explicit pitch controllability. The system achieves accurate pitch control comparable to digital signal processing baselines while maintaining high audio quality, performing on par with existing state-of-the-art neural methods. PitchFlower demonstrates resilience to input degradation, suggesting its framework can be extended to manipulate other speech attributes. AI

IMPACT This research could lead to more advanced audio generation and manipulation tools with fine-grained control over speech characteristics.

    PitchFlower: A flow-based neural audio codec with pitch controllability

    arXiv:2510.25566v2 Announce Type: replace-cross Abstract: We present PitchFlower, a flow-based neural audio codec with explicit pitch controllability. Our approach promotes pitch disentanglement through a simple perturbation: during training, F0 contours are flattened and randoml…
