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!
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.
The next example is a recording in a van, with changing engine and wind noises in the background.
This example is a cutted excerpt of a conference recording with a video presentation including music, talks, and
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.
The following recording by
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:
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!
