The first seven tools are dedicated clean-up tools: you give them a recording and get back a cleaner one. The last three are wider podcast platforms that include clean-up features such as filler-word removal alongside recording, editing or repurposing.

The best AI audio enhancers, reviewed

1. LALAL.AI

LALAL.AI is best known as a stem splitter, but its Voice Cleaner is what earns it a place here: it removes background music, plosives, mic rumble, echo and reverb from spoken audio. That makes it useful when a voice was recorded over music or in an echoey room, and the same account also gives you vocal and instrument stems for remixes or karaoke.

Standout features:

• Voice Cleaner removes background music, plosives, mic rumble, echo and reverb
• Splits tracks into vocals, drums, bass, guitars, piano, synth, strings and wind stems
• Separates lead vocals from backing vocals

Pricing: The Starter plan is always free but gives 10 minutes in the relaxed queue with a 200MB upload limit and no result downloads. Lite costs $7.5 a month ($90 billed annually) and Pro costs $15 a month ($180 billed annually). The VST plugin and API are on the Pro plan only.

How to choose

• You record a weekly podcast and want it to sound finished with no manual work: Auphonic handles noise, levelling and loudness in one pass, and Cleanvoice is the pick if filler words and dead air are the bigger problem.
• Your voice was recorded over music or in an echoey room: LALAL.AI Voice Cleaner targets background music, echo and reverb, and Adobe Podcast Enhance Speech is a free first try.
• You want cleaner audio during live calls, not after: CrystalSound works as a virtual mic and speaker in Zoom, Teams and Meet, and also cleans saved recordings.
• You only fix the odd file: pay-as-you-go tools such as Audo Studio and Audio Enhancer AI avoid a monthly subscription, and Audimee has a small free allowance.
• You want recording, editing and clips in one app: Riverside records each guest locally, while Podsqueeze turns finished episodes into show notes and clips after removing silences and fillers.

Most of these tools offer a free plan or trial, so the quickest test is to run the same noisy recording through two or three of them and compare the results.
