Auphonic vs Resound

Auphonic is an automated audio post-production web service for podcasts, broadcasts, radio, interviews, audiobooks, lectures and other audio or video projects. Its algorithms can reduce noise and reverb, adjust levels, filter and enhance recordings, meet loudness specifications, and remove filler words, coughs and silence. Multitrack processing creates mixdowns with automatic ducking, noise gates and mic-bleed removal. Auphonic also provides multilingual speech-to-text, automatic shownotes and chapters, and a shareable transcript editor. It supports common audio and video formats, waveform audiograms, metadata, chapters and burned-in styled subtitles. Integrations include storage, publishing, automation and speech-recognition services; workflows can use the API, CLI, watch folders and batch productions. The free plan is free and includes two hours per month, but free accounts do not include multilingual speech recognition, automatic shownotes and chapters, watch folders or batch productions. Free multitrack productions must be under 20 minutes. Billing has a three-minute minimum per production, and productions are deleted after 21 days for audio and API work or seven days for video.

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.
