| Output | Edited audio and video, transcripts, captions and short-form clips | Mastered music tracks and separated stems |
| What it does | Records, edits and publishes podcasts and video, with the edit driven by chat instructions instead of a timeline | Mastering finished music mixes, with stem separation and distribution around it |
| Noise removal and repair | Yes, Magic Dust removes background noise and clarifies the voice; a separate pass cuts filler words, pauses, repeats and bad takes | No, the engine masters a completed mix rather than repairing a damaged recording |

The trade-offs
Strengths and Limitations
Async
Strengths
- Records, cleans up, edits and publishes in one browser tool
- Editing by chat instruction rather than by timeline
- Turns one recording into clips, captions and a transcript
- Free plan available, and a developer voice API alongside the studio
Limitations
- The public pricing page names the plans but leaves the amounts blank, so a price has to be looked up in the help centre or in the app
- Metered in AI credits, so heavy months cost more regardless of seat count
- Free plan's AI credits and transcription are lifetime allowances, not monthly ones
- The vendor cautions that AI edits need reviewing
eMastered
Strengths
- Unlimited mastering, stem separation and distribution on one subscription
- Reference mastering against a track you choose
- A 20-second preview plays before any payment
Limitations
- No ongoing free tier, a download needs a subscription
- Masters a finished stereo mix only, not stems or tracked-out files
- The no-commitment rate is more than double the annual one
