Audio Tools
A voice memo that needs trimming, a podcast episode that needs converting before it'll upload to a platform, a music file that's too large to attach to an email — audio editing usually means either a dedicated app you'd only ever use once, or an online converter that quietly uploads your recording to process it.
Trimming, converting between MP3/WAV/M4A/OGG/FLAC and other formats, and compressing to a smaller bitrate all run through a real audio engine loaded directly into your browser — the same one used by the video tools here — so your recording is processed on your own device rather than sent anywhere.
