Audio workflow
Audio Tools
Local audio utilities for file conversion, editing, recording, analysis, and signal generation.
Audio tools are for operations where the primary object is sound: recording it, decoding it, editing the waveform, generating a signal, or exporting a new audio file.
This category intentionally excludes generic time tools such as stopwatches and countdown timers. Those belong to Time & Rhythm unless the audio signal itself is the main artifact.
The browser can decode and encode only the formats it supports, so some export options depend on the user’s browser. Where that matters, the tool page states the limitation directly.
