1. Podcastle
Best Overall AI Audio Enhancer
Podcastle transforms low-quality audio into studio-grade sound. It’s perfect for podcasts, as the name suggests.
Note that Podcastle isn’t just an audio enhancer—it’s a full podcasting platform where you can collaborate and share content.
But for this review, I’ll focus solely on its audio-enhancing capabilities.
Original vs. Enhanced Audio

As you can hear, the original clip is terrible. It’s a noisy recording I made with my iPhone connected to my headset.
But the AI-enhanced clip is almost magical.
Pros
- Realistic: The enhanced audio sounds almost like me. It’s far better than what free tools can achieve.
- Few artifacts: In the short clip, I didn’t notice any artifacts.
- No accidental clipping: Unlike free tools, this one doesn’t cut out silent parts it mistakenly identifies as noise.
- Easy to use: The tool is straightforward. Just sign up, upload your audio, and let the AI work its magic.
Cons
- Requires credit card: There’s a 7-day free trial, but you need to provide payment details to activate it. Don’t forget to cancel if you don’t want to be charged.
- Robotic speech: The lower the input quality, the more the AI has to guess, which can result in a clip that doesn’t sound like you.

Pros
After using Adobe Enhancer, the clip improved significantly:
- Noise removal: All background noise is gone.

- Overall improvement: The audio now sounds like it was recorded in a professional studio.
However, there are some drawbacks.
Cons
- Lisp: After enhancement, it sounds like I have a lisp.

Overall, I’m impressed with the results, especially since it’s a free tool.
