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 diarizationdemucs/— 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 totts/'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:
demucs— separate the source clip into vocals / instrumental stemswhisperx— transcribe the isolated vocal stem, then machine-translate the transcripttts— 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.
