Quick answers
Frequently asked questions
Can I work on several audio files at once?
Yes. Add up to five files and switch between tabs. Each file keeps its own trim, noise, volume, pitch, speed, and preview settings.
Will my audio session survive a reload?
When browser storage is available, Audio Workspace saves the original files and edit settings locally for recovery after a reload. Use Clear session to erase them. Exported WAV files are not stored.
What are the Audio Workspace limits?
Each file must be 40 MB or smaller and up to three minutes long. The complete saved session can use up to 80 MB. Codec, storage, and memory support vary by browser.
