The barrier between a podcast that sounds professional and one that sounds amateur is almost entirely audio quality. Most creators record with reasonable microphones but end up with recordings that still have background noise, inconsistent volume levels, and the telltale room echo that signals a home recording. Async’s AI audio enhancement tools address all of these problems automatically, giving creators a post-processing chain that produces studio-quality output from consumer hardware without requiring audio engineering knowledge.
Async is an AI-powered podcast recording and editing platform that provides browser-based multi-track recording, AI audio enhancement for noise removal and voice levelling, text-based editing, AI voice cloning, and one-click podcast distribution.
Is it worth using? Yes for podcast creators who want studio-quality audio output without professional audio equipment or editing knowledge, and who want recording, editing, and publishing in one place.
Who should use it? Podcasters, content creators, journalists, and anyone producing regular audio or video interview content who wants professional audio quality without an audio engineering background.
Who should avoid it? Professional audio engineers and podcast producers who use dedicated DAW software for precision audio work that browser-based tools cannot replicate.

Async, formerly known as Podcastle, is an all-in-one podcast creation platform that handles recording, editing, enhancement, and publishing from a single browser-based application. The platform rebranded to Async to better reflect its expanded capabilities across audio and video content creation for individuals, teams, and businesses.
Its AI audio tools automatically remove background noise, enhance voice quality, level inconsistent volume across speakers, and process recordings to broadcast-quality standards without manual EQ, compression, or noise gate configuration. The Magic Dust one-click enhancement feature has earned consistent praise from creators who describe it as the single biggest audio quality improvement available without changing their hardware.
Beyond audio enhancement, Async includes an AI voice cloning feature allowing creators to generate additional narration in their own voice from text without re-recording, useful for adding intros, outros, and corrections without returning to the microphone.
