Eliminate background noise and enhance audio quality on calls and recordings with this AI tool

Sold out

Nothing can ruin a work call like random background noise. (“Sorry, this is the only time my neighbor has to vacuum, play the trumpet, and practice tap dancing.”)

Remote meetings are so popular because of the convenience, so scheduling important conversations during late-night quiet hours doesn’t make any sense.

If only there was an AI-powered tool that could isolate your voice and make it sound like you’re speaking in absolute silence.

Make way for CrystalSound.

At-a-glance

Overview

CrystalSound is an AI-powered tool that eliminates unwanted noise and enhances audio quality on calls, online meetings, and recordings.

CrystalSound can suppress all background noise automatically, including animals, construction, and loud appliances.

Take it a step further and train the AI to isolate your voice even when others are talking nearby, which is perfect for crowded co-working spaces.

You’ll be able to access this app on any desktop operating system, including Windows, MacOS, and Linux.

And because CrystalSound integrates with any app that uses your microphone, like Microsoft Teams, Zoom, Google Meet, and Slack, it’ll fit right into your tech stack.

Voice isolation

Create voice isolation profiles to filter out the noise of other people speaking near you.

CrystalSound also helps you eliminate background noise on the other end, making it easy to hear folks, no matter what’s going on.

This is super useful for call centers and other customer support roles where hearing the other person clearly can yield faster results.

You can adjust the strength of noise removal with a simple slider, letting you remove anything from car horns to loud barking in their living room.

Noise removal

Remove background noise on the other side of the call with a simple slider.

With CrystalSound, you can also apply fun effects like reverb or a robot filter to your voice with just one click.

So whether you’re a voice actor going for a spooky vibe or trying to add some life to a Zoom meeting, this app has you covered!

Plus, you can activate useful effects such as echo removal or even voice smoothing to help reduce choppy audio when your wifi is acting up.

Audio E=effects

Set CrystalSound as your default microphone to activate fun audio effects.

Best of all, CrystalSound lets you apply voice isolation and noise removal to audio recordings in seconds—no fancy audio editing tools required!

This feature works with audio files of any length, ranging from a few minutes of narration to hours of podcast audio.

You can also equalize volume across the clip to raise the audio when it’s too low and reduce it when it’s too high for a better listening experience.

Audio files

Enjoy crystal-clear audio on all your audio files from voiceovers to full-length podcasts.

You should be able to jump on a call anywhere, without shushing the folks spilling tea next to you. (“My whole team can hear you and they’ve got questions about your cousin’s boyfriend.”)

That’s why CrystalSound uses powerful AI technology to remove all unwanted background noise during calls, audio recordings, and online meetings.

Let your voice be heard.

Q: Krisp does transcriptions and then meeting notes with summaries (long and short) as well as action items (all 3 are done by AI).

Is this in the works for your platform? I use this daily.

A: Dear David2175,

We don't support these features. They will be short summary in the future post call but that's it. We don't have intention to add transcriptions.

A: Dear Shopaholic,

In audio, mean-opinion-score (MOS) is the golden standard for rating different algorithms/audio processing software. In our MOS test on Amazon Mechanical Turk, CrystalSound and Krisp is fairly equal, and we even have modestly higher score (margin of 0.1-0.2). However, MOS is an average of subject opinion so a rating of 3.6 vs 3.5 does not imply one is always better than another. In fact, there could be 40% of users prefers 3.5 MOS app over 3.6 app.

That's to say, IMHO, CrystalSound meets quality of Krisp in most cases and on most devices. However, we are a young team and doing audio processing on end-user devices is a complicated matter to say the least. So, I want to acknowledge that we have to work hard to meet Krisp stability.

BRs,
Anh
