What Resound is
Resound is an AI editing app for podcast creators that automates parts of audio cleanup. It identifies filler sounds such as ums and ahs, and finds silences longer than three seconds that users may want to shorten. Suggested edits can be reviewed, and audio can be trimmed with click-and-drag controls. Its Enhance tools remove background noise, level and normalize audio, and prepare it for export. Users can upload single-track or multitrack audio and export WAV, MP3, or AAF files as merged or individual tracks. The Free plan includes 20 minutes of processed audio, one track per project, one-day project storage, trimming, filler and silence detection, and MP3 export. Creator costs $15 a month and includes four hours of processing, two tracks per project, and 15-day storage. The 14-day trial provides one hour of AI processing and access to all features. Processing time is charged per project based on its longest file, and unused hours expire at the billing period's end. Resound also offers an API that returns edit predictions in JSON, but access requires approval.
