Why this category?
Why use audio tools?
Audio files often need several operations before they are ready to share or reuse. This category brings conversion, trimming, volume adjustment and merging into consistent tools that can be used on their own or reused as transformations inside the Workspace.
Processing is built around one shared audio engine so tools, widgets and pipelines apply the same operations. The current POC prioritizes local browser processing and dependable WAV output before additional formats are evaluated through a lazy-loaded FFmpeg/WASM backend.
Use cases
Prepare an audio excerpt
Trim the useful part of a recording without uploading the source file to a server.
Adjust audio level
Increase or reduce a file's volume before using it in another piece of content.
Combine several files

Frequently asked questions
Are audio files uploaded to a server?
No for the processing currently covered by the POC: operations run locally in the browser.
Which output formats are available?
The POC currently uses WAV as its dependable output. More formats will be evaluated with a lazy-loaded FFmpeg/WASM backend.
Can these operations be reused in a pipeline?
Yes. Compatible audio transformations reuse the same engine across tools, widgets and Workspace modules.
