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 of our Dynamic Denoiser.
The next example is a recording in a van, with changing engine and wind noises in the background.
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:
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 removes everything else, including music, from your audio.
In this example (Freak Show 136), one speaker is breathing directly into the microphone, which creates a Darth Vader-like effect.
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 eating is for the sound. Listen to how the chewing and smacking sounds are removed after processing with the Dynamic Denoiser:
For the demonstration of our Static Denoiser, we processed a snippet from the German audio drama Der Graue. The Static Denoiser perfectly preserves all the sound effects while removing reverb and static noise. In contrast, the Speech Isolation (or for this file without music, the Dynamic Denoiser) removes everything from the audio that is not speech:
In this excerpt from the History of Jazz podcast, our Static Denoiser removes only the steady background noise while keeping the musical
texture intact, regardless of how experimental, spherical, or noise-like the music sounds.
By contrast, our Speech Isolation Denoiser removes everything except the speech - including music,
background vocals, and ambience - resulting in a completely clean, voice-only version of the same excerpt.
For both denoised versions, we also applied our Voice AutoEQ + Bandwidth Extension filtering algorithm to enhance the speech quality,
producing a brighter, fuller-sounding voice.
