Reagent can analyze your audio files directly—detecting silence, finding transients, measuring loudness, and even classifying sounds into UCS categories. These tools work on both standalone audio files and media items in your REAPER project.
You don’t need to remember tool names. Just describe what you want and Reagent picks the right tool.
| Tool | What it does |
|---|
| Silence Detection | Finds quiet sections in your audio—useful for trimming dead space or splitting at pauses |
| Transient Detection | Locates hits, attacks, and percussive moments in your audio |
| Loudness Measurement | Measures overall loudness (RMS) of a sound or specific section |
| Spectrum Analysis | Shows where the energy is across frequency bands (sub, bass, mids, highs) |
| Waveform Extraction | Gets the shape of your audio for visualization or analysis |
| Tool | What it does |
|---|
| Read Metadata | Extracts embedded info from audio files (tags, technical specs, UCS data) |
| Write Metadata | Embeds UCS categories, descriptions, and production info into your files |
| Tool | What it does |
|---|
| UCS Classification | Uses custom-trained model to suggest the best Universal Category System CatID based on audio features |
| Format | Extension | Read | Metadata Write |
|---|
| WAV | .wav | ✅ | ✅ |
| MP3 | .mp3 | ✅ | ❌ |
| FLAC | .flac | ✅ | ✅ |
| Ogg Vorbis | .ogg | ✅ | ❌ |
What metadata is in this file?
Show me the UCS info for the selected items
| Standard | Description |
|---|
| RIFF INFO | Standard WAV metadata chunks (title, artist, etc.) |
| BWF/BEXT | Broadcast WAV Extension for professional audio |
| iXML | Production metadata (scene, take, tape) and UCS extensions |

| Vorbis Comments | OGG and FLAC metadata |
Embed metadata directly into your audio files.
Add UCS metadata to the selected items with category VEHCar
Tag these files with creator "John Smith" and source "Field Recording 2024"
| Format | Standards Written |
|---|
| WAV | RIFF INFO, BWF/BEXT, iXML (with UCS extensions) |
| MP3 | ID3v2 (standard frames + TXXX for UCS fields) |
| FLAC | Not yet supported |
| System | Use Case |
|---|
| UCS | Sound effects library organization (CatID, category, subcategory, creator, source, keywords) |
| BWF/BEXT | Broadcast production (originator, description, originator reference) |
| iXML | Film/TV production (show, scene, take, tape, notes) |
| Standard Tags | General audio metadata (title, artist, album, description, copyright) |
Metadata writing modifies the original files. REAPER items referencing these files will reflect the updated metadata.
