Resound AI Podcast Editor and Audio Enhancement Tool

Resound is an AI-powered podcast editing platform designed for creators who want to reduce hours of manual post-production work. Built by professional audio engineers behind Culpable and 15 other number-one shows on Apple Podcasts, Resound automates tedious editing tasks by detecting filler sounds, long silences, and background noise so creators can focus on their message rather than cleaning up audio mistakes.

Key Features

Filler Sound Detection: Resound uses proprietary machine learning models to identify unwanted filler sounds like umms, ahhs, ehhs, and errs that distract listeners. The AI flags these for review so creators can remove them with a single click.
Silence Detection: The tool automatically finds silences longer than three seconds in audio, helping creators shorten episodes, improve pacing, and boost listener retention without scrubbing through waveforms manually.
Trim Audio: A click-and-drag interface lets users make precise cuts. Creators can refine content by removing sections they do not want published while maintaining full control over what stays and what goes.
Enhance with AI Mixing and Mastering: Resound can automatically mix and master podcast audio with one click. Powered by Auphonic, the Enhance feature removes background noise and reverb, levels and normalizes dialogue, and exports at optimal loudness standards for podcast platforms.
Multitrack Editing: Paid plans support up to four tracks per project, making Resound suitable for interview podcasts, roundtable discussions, and co-hosted shows where each speaker is recorded on a separate track.
Multiple Export Formats: Resound exports episodes as MP3, WAV, AAF, and MP4 files. The AAF export supports handoff to professional DAWs like Pro Tools and Logic Pro for creators who want to add intro music or additional edits.

How Resound Works

The editing workflow follows four steps. First, creators upload unedited single-track or multitrack audio files by dragging and dropping into the upload area. Resound accepts all major audio formats and can strip audio from video files like MP4 and MOV. Second, the AI analyzes the audio to identify filler sounds, extended silences, and other potential edits. Third, creators review each suggested edit, choosing to cut or keep it, and preview how the edited audio will sound. Fourth, they export the finished file in their preferred format, either as a merged file, individual tracks, or both.

Pricing and Plans

Resound offers four pricing tiers with a 14-day free trial that includes one hour of AI processing time and access to all features.

Free: $0 per month with 20 minutes of processed audio, filler and silence detection, trim, MP3 export only, one track per project, and one day of project storage.
Creator: $15 per month with 4 hours of processed audio, all detection features, MP3, WAV, AAF, and MP4 exports, two tracks per project, 15 days of project storage, and the Enhance feature with four AI voice filters.
Professional: $30 per month with 10 hours of processed audio, MP3, WAV, AAF, and MP4 exports, four tracks per project, 30 days of project storage, and Enhance.
Studio: $60 per month with 30 hours of processed audio, four tracks per project, 60 days of project storage, Enhance, and API access for integrating AI editing into custom workflows.

Processing time is calculated at the project level based on the longest file, not the sum of all tracks. Unused hours expire at each billing period. Users who exceed their limit can upgrade immediately with prorated billing or wait until the next billing cycle.

Pros and Cons

Pros:

Built by professional audio engineers with real podcast production experience, giving the tool an understanding of actual creator workflows.
Proprietary machine learning models specifically trained for podcast audio rather than repurposed general speech models.
Full control over edits: the AI suggests cuts but creators make the final decision on every change.
Affordable entry point at $15 per month for the Creator plan, with a free tier available for light users.
AAF export format supports professional DAW workflows for creators who need advanced post-production in Pro Tools or Logic Pro.

Cons:

The Free plan limits processing to 20 minutes per month and only supports single-track projects, which is insufficient for regular podcasters.
Project storage is time-limited across all plans, ranging from one day on the Free plan to 60 days on Studio, so creators cannot keep projects accessible indefinitely.
Several announced features including repeat detection, filler word detection, stutter detection, and native video exports remain in development.

Who Should Use Resound

Resound is a strong fit for independent podcasters, interview-show hosts, and small production teams who want to cut editing time without sacrificing control over the final product. The Creator plan at $15 per month makes it accessible for hobbyists and early-stage creators producing one to four episodes per month. Professional podcasters and networks with higher volume needs will benefit from the 10 to 30 hours of processing time on the Professional and Studio plans. The tool is less suitable for creators who need long-term project storage or rely heavily on video publishing, since video export features are still in beta and not all announced capabilities are available yet.
