AuK's loader (librosa/soundfile) can't read compressed containers like
m4a/mp3 at all - only demucs's loader handles those. Gradio keeps
uploads in their original format, so any edit attempted directly on an
uploaded m4a failed with "Format not recognised."
Normalize to wav via ffmpeg at the single point a reference is set
(use_as_reference), so both AuK and MOSS-TTS downstream always see wav
regardless of what was uploaded.

Gradio app that orchestrates the three existing isolated venvs via
subprocess (their dependencies conflict too much to merge into one
environment - MOSS-TTS needs transformers 5.0.0, AuK needs 4.57.6).
Lets you strip a voice, iteratively edit it (emotion/pitch/speed/custom
instruction) with preview and undo/reset after each step, then generate
new speech in the resulting voice - addressing the trial-and-error
workflow the pitch-overshoot investigation needed.
Also extracts tts/generate.py as a reusable, general-purpose MOSS-TTS
cloning CLI (text/reference/language/output args) rather than one-off
personal scripts.
Verified all three stages end to end via direct function calls before
wiring up the UI.
