# Producer
Local speech cleanup and mastering for voice recordings. Noise removal uses
ClearVoice or DeepFilterNet3; speech-aware pause silencing uses Silero VAD.
Filtering, dynamics and loudness normalization use FFmpeg. Audio stays local.
`producer.sh` bootstraps its own managed Python environments and downloads
dependencies and models automatically.
## Requirements
- glibc >= 2.28 for AI denoising and speech detection
- `uv` (or Python 3)
- NVidia driver and toolkit (optional)
## Usage
```bash
git clone https://git.historia.vg/git/producer
./producer.sh setup --denoiser clearvoice
./producer.sh recording.wav
```
First run installs the runtime into `lib/runtime/`
The master WAV is **mono, 32-bit PCM**. Loudness is normalized to **-19 LUFS with a -1.5 dBTP true-peak ceiling**. In `config.toml` you can edit the sample rate (48/44.1 kHz), MP3 bitrate, loudness, etc.
### Examples
```
# Optional MP3 alongside the WAV
./producer.sh recording.wav --mp3
# Other sound profiles
./producer.sh recording.wav --profile narrator
./producer.sh recording.wav --profile radio
# Process several files at once
./producer.sh take1.wav take2.wav --mp3
# LibriVox-style delivery file: 44.1 kHz, 128 kbps CBR, -19 LUFS
./producer.sh recording.wav \
--sample-rate 44100 --mp3 --mp3-bitrate 128 \
--target-lufs -19 --true-peak-db -1.5
```
Edit default settings in `config.toml`
## Optional local browser GUI
```bash
./producer.sh gui [--port 8766]
```
Servers a local web page on `127.0.0.1` where you pick a WAV, tune settings, render an A/B
comparison, and export.
## Profiles
| Profile | Sound |
| -------------- | --------------------------------------------------------- |
| `natural` | Mild EQ, 2:1 compression, light de-essing (default) |
| `narrator` | Gentler compression, slower attack, wider loudness range |
| `radio` | Stronger compression, more warmth/presence, tighter range |
| `cleanup-only` | Denoise + highpass only; no EQ, dynamics or normalization |
