Audio Tools

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.

The Toolbox

You don’t need to remember tool names. Just describe what you want and Reagent picks the right tool.

Analysis Tools

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

Metadata Tools

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

Classification Tools

Tool	What it does
UCS Classification	Uses a custom-trained model to suggest the best Universal Category System CatID based on audio features. Works with all audio formats

Supported Formats

Format	Extension	Read	Metadata Write
WAV	`.wav`	✅	✅
MP3	`.mp3`	✅	❌
FLAC	`.flac`	✅	✅
Ogg Vorbis	`.ogg`	✅	❌

Metadata

Reading Metadata

Extract embedded metadata from audio files. Works with WAV, MP3, FLAC, and OGG files.

What metadata is in this file?

Show me the UCS info for the selected items

Supported standards:

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
ID3v2	MP3 metadata tags
Vorbis Comments	OGG and FLAC metadata

Writing 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"

What gets written by format:

Format	Standards Written
WAV	RIFF INFO, BWF/BEXT, iXML (with UCS extensions)
MP3	ID3v2 (standard frames + TXXX for UCS fields)
FLAC	Not yet supported

Supported metadata systems:

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.
