Podcastle Audio Enhancement
Now Async — Record clean audio on any microphone and have the AI polish it automatically before you even open an editor — noise reduction voice enhancement and magic dust in one step.
Worth knowing upfront: Podcastle has rebranded as Async, and podcastle.ai now redirects to async.com. Async's site currently leads with AI video editing, so check async.com to confirm which of the podcast recording, voice cloning and audio enhancement features and plans described below are still offered. There's a certain sigh of relief when you finish a recording, and the waveform looks decent to begin with. Podcastle automates that process for podcasters; it injects that feeling of relief into the recording process itself instead of making it a separate step in post-production. The most common feature users first notice with Podcastle is their Magic Dust. Magic Dust is applied to your recording on automatic – it cleans up ambient noise, improves the clarity of your voice, and otherwise does exactly what's needed to make your audio sound better, all without you having to intervene on settings or configurations. It's not nearly as robust as other professional applications such as iZotope RX, and you also lose out on control/adjustability, but for the people it serves – podcasters who just want to get an episode produced without thinking about audio engineering – it works extremely well at what it's designed to do. Because the improvement happens in the recording process itself, when you're in the editing stage, the audio has already been improved. This is unlike an improvement that requires you to record, export, and import the recording into your audio editor and then process it, which adds hours over the month, in turn cutting productivity time – save an obvious amount of hours month on month. To be fair, for me, audio enhancement is slightly below. Adobe Podcast Enhance and Descript Studio Sound in terms of overall audio enhancement quality in benchmark tests. I found it 'solid' at best, not 'exceptional', but for podcast editors who want AI audio improvement with their recording workflow inside of Podcastle, they absolutely can achieve that without the use of a separate application or by creating additional steps.

Pros & Cons
Pros
- Enhancement integrated into the recording workflow means audio is treated before the editing session begins rather than as a separate step
- Automatic processing without settings decisions suits podcasters who do not want to think about audio engineering
- Browser-based workflow with built-in enhancement requires no external software or audio tools for basic podcast production
- Solid cleanup quality for the most common podcast audio problems from home recording environments
- Complete recording-to-publishing workflow means fewer separate tools needed for a functional podcast production process
Cons
- Enhancement quality sits below Adobe Podcast Enhanced Speech and Descript Studio Sound on pure audio cleanup power in independent testing
- Less configurability than dedicated audio tools — no intensity control parameter adjustment or manual override of the automatic processing
- Best value when used within the Podcastle ecosystem and less compelling as a standalone audio enhancement tool compared to free alternatives
- Storyteller plan at $23.99 per month required for full feature access with the free plan too restricted for regular production use
