Noise & Reverb Reduction

Please click inside the waveform to zoom and scroll through the audio - each example is divided into multiple segments and annotated with details about the algorithms. We recommend listening with headphones so you can hear all the details!

1. Changing ambient sounds, noise reduction amount demonstration

Here we have an outdoor recording with lots of changing environment sounds. You can choose to remove all ambient sounds completely or to just reduce them for improved speech intelligibility using the parameter Noise Reduction Amount.

Original:

Denoised with Dynamic Denoiser:

Denoised with -12dB reduction amount: sounds more natural, but still improves speech intelligibility

The next example is a recording in a van, with changing engine and wind noises in the background.

2. Removing reverb and wind noises

The following recording by conduitministries.com includes two very different parts.
The first part is recorded in a very reverberant room and our denoising algorithms also remove the reverb:

The second part is recorded outside, with lot's of wind noises:

3. Remove or keep music? Dynamic vs. speech isolation denoiser

This example is a cutted excerpt of a conference recording with a video presentation including music, talks, and discussions.
It can be used to show the difference between our dynamic and speech isolation denoiser: The dynamic denoiser keeps speech and music, but removes all other stationary and non-stationary noises, and the speech isolation denoiser only keeps speech and remove everything else, including music, from your audio.

Noisy:

Speech Isolation denoising: completely removes the background music between 00:00 and 00:48 and noises afterwards

Denoised with Dynamic Denoiser: keeps the background music, after 00:48 it's the same as speech isolation

4. Eliminate breathing sounds, mouth clicks and eating noises

In this example (Freak Show 136), one speaker is breathing directly into the microphone, which creates a Darth Vader-like effect.

Denoised with Speech Isolation and "Remove Breathing" option:

The following example from the podcast (SWR2 Wissen) demonstrates the elimination of wet mouth clicking sounds using the Dynamic Denoiser:

The next example is an excerpt from the (Joe Rogan Experience #2054) where Elon Musk and Joe Rogan are eating pizza and talking about how terrible it is for the sound. Listen to how the chewing and smacking sounds are removed after processing with the Dynamic Denoiser:

5. Static vs. dynamic denoiser

Another short excerpt of the previous conference recording in example 2 also serves well to demonstrate the difference between our static and dynamic denoiser.
The static denoiser removes only stationary, technical noises, while our dynamic denoiser removes everything but speech and music. In this example, there are non-stationary microphone rumbles, clicking sounds, and paper sliding noises deleted from the record.
Please pay attention to not use the dynamic denoiser, if you want to keep sound effects or ambient sounds in any kind of audio play content!
