Auphonic vs Podcastle

Auphonic is an automatic audio post-production service from Graz, Austria. You upload a recording, pick a preset, and its algorithms level loudness between speakers, normalize to broadcast and podcast targets such as -16 LUFS, remove noise and hum, filter out low rumble and balance multitrack recordings so every voice sits at the same level. It then encodes the result in the formats you need and can publish straight to podcast hosts, YouTube, Dropbox or an FTP server.

Beyond cleanup, Auphonic adds speech recognition for transcripts and subtitles, automatic chapter marks, cut detection for fillers and silences, and ID3 metadata with cover art. Pricing is based on processing hours: a free tier gives two hours a month, recurring plans add more hours each month, and one-time credits never expire, which suits shows that publish irregularly. A REST API and desktop apps let teams automate the whole pipeline.

It is ideal for podcasters, radio stations, universities and video producers who want consistent, professional sound without learning mixing. It is not an editor: you cannot cut a story or rearrange segments, so it is usually paired with Audacity, Descript or a DAW. Compared with Adobe Podcast Enhance, Auphonic gives more control over loudness targets and output formats; compared with manual processing in iZotope RX, it is faster and far cheaper but less precise on difficult recordings.

Podcastle is an AI-powered podcast and video creation platform founded in 2020 by Artavazd Yeritsyan, with a large part of its team in Armenia. It aims to give independent creators a single browser-based studio for recording, editing, enhancing and publishing audio and video podcasts.

Remote recording captures each participant locally in high quality and uploads progressively, so internet hiccups do not ruin the take. Editing is text-based: you cut words from the transcript and the media follows, alongside a traditional multitrack timeline. Magic Dust removes noise and echo and makes laptop microphones sound closer to studio recordings, and AI tools add voice cloning, text-to-speech with stock voices, automatic transcripts, captions, silence removal and loudness normalization. The product is now sold under the Async brand; a free plan with a few lifetime AI credits covers basics, and paid Essentials, Pro and Teams tiers add monthly AI credits, more storage and up to 4K export.

Podcastle fits solo podcasters, small teams and marketers who want one affordable tool instead of combining a recording service and an editor. Professional productions usually prefer Riverside for recording quality and production features and Descript for deeper editing and screen recording, both more mature and better integrated. Adobe Podcast is a strong free option for audio cleanup alone, and Zencastr is another budget-friendly remote recording studio.
