Spec score 8.5 #7 of 26 in AI Podcast Editing Software

What it is

Resound is an AI audio-editing app built to automate parts of podcast cleanup. It detects filler sounds such as ums and ahs, and finds silences longer than three seconds for users to consider shortening. Editors can review suggested changes and trim audio by dragging. Enhance tools remove background noise, level and normalize sound, and prepare it for export. Resound accepts single-track and multitrack uploads, with WAV, MP3, or AAF exports as merged files or separate tracks. The Free plan provides 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 processing hours, two tracks per project, and 15-day storage. A 14-day trial offers one hour of AI processing and access to all features. Processing is charged per project according to its longest file, and unused hours expire at billing-period end. The API returns AI edit predictions in JSON, but access requires approval.
