# DDSP Timbre Transfer

Differentiable DSP timbre transfer: recast your audio in the timbre of a pretrained instrument (Violin, Flute, Trumpet, ...). Runs the original, unmodified DDSP stack in an isolated Python 3.9 backend.

Dual-interpreter HARP Space: a pyharp/Gradio frontend (Python 3.10) drives an isolated model backend (Python 3.9) via a one-shot subprocess, so the backend's pinned dependencies never touch pyharp/Gradio.

- Inputs: audio, dropdown, slider, checkbox, slider, slider, slider, slider
- Outputs: audio

Generated by the HARP model agent from a recipe.
