What Resound is
Resound is an AI editing app for podcast creators that identifies filler sounds and long pauses so they can review and trim audio. It detects sounds such as ums and ahs, and finds silences longer than three seconds. Users can inspect proposed edits and trim with click-and-drag controls. Enhance tools remove background noise, level and normalize sound, and polish audio for export. Resound accepts single-track or multitrack uploads and exports WAV, MP3, or AAF files as merged or individual tracks. The free plan costs nothing and includes 20 minutes of processed audio, one track per project, one-day project storage, trim and detection tools, and MP3 export. Creator costs $15 / Mo and provides four processing hours, two tracks per project, and 15-day storage. New users can also try all features for 14 days, with one hour of AI processing. Processing time is charged by project according to its longest file, while unused hours expire at the billing period's end. Its API returns edit predictions as JSON, but access requires approval.
