Auphonic vs Transistor

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.

Transistor is a podcast hosting platform for businesses and professional creators, founded by Justin Jackson and Jon Buda and run as a small independent company. Its core job is reliable hosting and distribution, with features designed for companies and creators who run multiple shows or private podcasts.

Every plan includes unlimited podcasts, which is unusual in the category, so a single account can host a company's entire podcast portfolio. Episodes are distributed to Apple Podcasts, Spotify, YouTube Music and all major directories, and analytics break down downloads by episode, app, country and trend. Each show gets a podcast website and embeddable players. Private podcasts let you publish internal shows for employees or premium feeds for paying subscribers, with subscriber management and integrations with tools such as Memberful and Zapier. Transcripts, dynamic ad insertion and team members are also supported. Pricing depends on total monthly downloads across all shows rather than the number of shows, and a free trial is available instead of a free plan.

Transistor fits companies running branded or internal podcasts, agencies hosting client shows and professional podcasters. It has no free tier and fewer built-in monetization options than Acast, and it does not include recording or editing. Buzzsprout is friendlier for beginners, Captivate offers strong growth tools, Acast suits ad-driven shows, and Spotify for Creators provides free hosting for hobbyists.
