ai-coustics Reviews & Product Details

ai-coustics is a Berlin-based deep-tech company building the audio intelligence layer for Voice AI. Founded in 2022 by researchers in audio, acoustics, and machine learning, the company focuses on the fundamental reliability problem that causes voice systems to fail outside controlled environments. Rather than competing with ASR, LLMs, or TTS, ai-coustics makes them reliable across all languages. Its SDK and model infrastructure sit at the boundary between real-world sound and machine understanding, conditioning raw audio into stable, machine-ready input optimized for downstream behavior. The company’s Quail model family delivers real-time speech enhancement, speaker isolation, and voice activity detection designed specifically for production of Voice AI. The Sparrow family, on the other hand, cleans up audio for human-to-human use cases as it's optimized for perceptual quality. ai-coustics powers voice agents, transcription pipelines, and telephony systems used by customers across Europe and North America, including LiveKit, Phonely, and Upstart. Backed by Connect Ventures, Partech, Inovia Capital, and angel investors from DeepMind, Hugging Face, and Amazon, the company is building a category-defining standard for Voice AI reliability. ai-coustics' mission is to make audio input reliable, measurable, and easy to deploy, so voice systems can operate with confidence in the environments where real people actually speak.

"The best noise remover I've come across!"

5/5

What do you like best about ai-coustics?

To test this tool I used an voice memo recording on my phone, where I was humming lyrics while a drum beat was playing in the background, and the result was immaculate. In the recording my voice was barely audible, in the output, there is literally just my voice. It is as just uploading the audio, and it does the job. I have tried many noise suppressors in the market, but nothing ever worked this well! Review collected by and hosted on G2.com.

What do you dislike about ai-coustics?

None so far! This is a very simple function for a simple need : to remove noise from vocal audio. Review collected by and hosted on G2.com.

"Amazing tool for video production"

5/5

What do you like best about ai-coustics?

The audio cleanup is a life saver!

It really makes the voice of people I record pop, whatever the conditions.

The video file support makes it easy and quick to enhance my audio directly from recordings.

I use it whenever I'm not happy with clarity of voice in clips or the amount of background noise - instead of spending long time tweaking the audio myself. Review collected by and hosted on G2.com.

What do you dislike about ai-coustics?

It can take some time to enhance longer recordings and it's not possible yet to batch download the done files. Review collected by and hosted on G2.com.

"Not impressed - Can't download processed files - Service not response - Cancel subscrip. difficult"

0/5

What do you like best about ai-coustics?

So far: nothing. The advertised service does not work. Review collected by and hosted on G2.com.

What do you dislike about ai-coustics?

I bought a subscription and uploaded a 45 minute audio. The audio got processed and I could listen to the processed version. So far, so good. Downloading the file always aborted with an error message that the mixed file could not be created.

I wrote to their team but had no response for three days now. Also tried to cancel the subscription which either can not be done on their website or I am too stupid to find it. So I had to go to their payment processior and try my luck there …

Overall: While the idea of the service seems great, the outcome is far from it.

For the time being my recommendation is: Avoid. Review collected by and hosted on G2.com.

Hi there,

I’m really sorry to hear about the issues you’ve experienced, and I completely understand how frustrating the delays and difficulties must have been. We’re here to help resolve this for you.

Regarding the file download issue, it’s good to know that the enhancement process worked and you could listen to the file. The problem you encountered with the download could be due to browser settings (like blocked pop-ups). If you're still facing difficulties with downloading, please feel free to contact us directly so we can assist you in resolving this promptly.

In terms of your subscription, you can cancel directly through the payment portal (LemonSqueezy), but if it’s easier, just share your email with us and we’ll take care of it for you. While account deletion is currently handled by request, we’re working on making that easier in the future as we grow. Thank you for highlighting this issue, we’ll make the information more accessible moving forward.

You should have already received a response to the email we received, which was forwarded to us by our payment provider, though unfortunately, it reached us with a delay. For quicker assistance in the future, feel free to contact us directly through our support email or on Discord. Could you let us know how you first reached out so we can improve our process?

We really value your feedback and want to make sure everyone has a smooth experience with ai|coustics. Please let me know if there’s anything else we can do.

"Not working, horrible support, don't use it"

What do you like best about ai-coustics?

If it would work it would be really simple. Review collected by and hosted on G2.com.

What do you dislike about ai-coustics?

Uploaded my 20-minute file for my 1h/month plan. It did not process at all and used up my full 1h processing time for no apparent reason. The support was not able to respond to my inquiry at all. Horrible product, and horrible support. Review collected by and hosted on G2.com.

"ai|coustics - Best Audio Enhancing Tool"

5/5

What do you like best about ai-coustics?

The use of deep learning to enhance audio works very well. It's intuitive and therefore easy to use.The output is easy to access and download. Review collected by and hosted on G2.com.

What do you dislike about ai-coustics?

It doesn't give the user an option to vary the level of enhancement needed in the audio, apart from the default 3 levels. If it could allow only the background noise, that would be a good feature to have. Review collected by and hosted on G2.com.
