Vocoder and Audio Tools

Use this sub-skill when a task is about Coqui TTS vocoder configuration, vocoder checkpoint compatibility, vocoder training preparation, or reusable audio preprocessing/analysis utilities.

Route by task

If the user needs...	Read/use
Vocoder model names, config classes, setup_model, default pairing, or mel compatibility checks	references/vocoder-reference.md and scripts/validate_vocoder_config.py
AudioProcessor settings, dataset statistics, safe resampling, VAD trimming, or spectrogram preconditions	references/audio-tools.md and the bundled audio helper scripts
Vocoder training command construction, HifiGAN recipe patterns, resume/restore semantics, or Trainer flags	references/training-workflows.md
Audio/vocoder failure diagnosis	references/troubleshooting.md, then the root cross-cutting troubleshooting reference when present

Bundled helper scripts

Run helpers from the generated TTS skill tree; they use the installed TTS package and user-provided configs/data, not the original repository checkout.

• scripts/validate_vocoder_config.py: load a vocoder config, validate audio/data/feature/statistics fields, optionally compare against a TTS config, and optionally instantiate the vocoder model without training.
• scripts/compute_audio_stats.py: compute bounded mel/linear mean-variance statistics for a wav directory using a Coqui audio config.
• scripts/resample_audio_dir.py: safely resample a directory into a separate output tree by default; in-place mutation requires --in-place.
• scripts/trim_silence_vad.py: wrap Silero/Coqui VAD trimming with explicit cache/network acknowledgement; --help does not download a model.

Boundaries

• Route TTS model config, dataset formatter, tokenizer, phonemizer, speaker embedding, and TTS training tasks to ../training-config-data/SKILL.md.
• Route installed tts synthesis commands, server commands, and command-line synthesis with a selected vocoder to ../server-and-cli/SKILL.md.
• Route Python model-registry and public TTS.api.TTS inference tasks to ../inference-and-model-zoo/SKILL.md.
• Route FreeVC and source/target/reference voice-conversion workflows to ../voice-conversion/SKILL.md.

Do not run full vocoder training, model-zoo downloads, VAD first-download runs, or native repository tests unless a later verification task explicitly authorizes that cost.
