Adobe Podcast's Enhance Speech tool became the go-to audio rescue option for podcasters the moment it launched, and it's held that reputation. The free version, which requires no account and processes files through a simple web interface, cleans up background noise, HVAC hum, room reverb, and mic proximity issues better than most paid competitors. The results on genuinely bad recordings, a guest on speakerphone in a coffee shop, for example, are remarkable enough that experienced podcasters use it as a standard step for difficult guest audio.
The limitation is scope. Adobe Podcast is primarily an audio enhancement and transcription tool, not a full editing or recording platform. If you're already paying for Adobe Creative Cloud for other Adobe tools, the podcast features are a no-brainer add. If you're building a podcast-only workflow, you'll want to combine it with Descript or Riverside for recording and editing rather than treating it as a standalone platform.
