# Producer

[](lib/demo.webp)

Local speech cleanup and mastering for voice recordings. Noise removal, speech-aware pause silencing, filtering, dynamics, and loudness normalization 

## 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 |
