Edits emotion on an existing recording in place (same speaker, words, duration) rather than steering style at generation time. Demo runs "Change the emotion to excited." on the public-domain narrator clip already used by whisperx/tts. Found and documented three real environment/packaging gaps on the RTX 3090: a missing audioread dependency, a huggingface_hub/transformers version conflict from installing the hf CLI, and --cpu_offload being mandatory (not optional) since AuK's own undoffloaded VRAM figures exceed 24GB entirely. Also found the practical input-length ceiling is ~25-30s, not the several minutes a podcast episode would need — an 80s clip OOM'd on attention memory even with offload enabled.

# audio-demo
|
|
|
|
Audio processing demos: WhisperX, Demucs, and TTS technology proofs-of-concept.
|
|
|
|
## Structure
|
|
|
|
- `whisperx/` — speech-to-text with word-level alignment and diarization
|
|
- `demucs/` — source separation (vocals/instrumentals stem splitting)
|
|
- `tts/` — text-to-speech service demos (voice cloning via MOSS-TTS)
|
|
- `auk/` — voice *editing* demos (emotion/pitch/speed/content editing on existing recordings,
|
|
as opposed to `tts/`'s clone-and-generate approach)
|
|
|
|
Each subdirectory has its own README with setup and run instructions.
|
|
|
|
## Requirements
|
|
|
|
Some demos are GPU-accelerated and are best run on a CUDA-capable machine (e.g. an RTX 3090).
|
|
|
|
## Planned: full audio-translation demo
|
|
|
|
Chain the three demos together on `media-files/` into an end-to-end pipeline:
|
|
|
|
1. `demucs` — separate the source clip into vocals / instrumental stems
|
|
2. `whisperx` — transcribe the isolated vocal stem, then machine-translate the transcript
|
|
3. `tts` — clone the original speaker's voice (from the isolated vocal stem) and synthesize
|
|
the translated text in that voice, then remix with the original instrumental stem
|
|
|
|
Stem separation and transcription are already working end to end (see `demucs/README.md` and
|
|
`whisperx/README.md`); translation and voice-cloning TTS are not yet implemented.
