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!
The following example is a recording with the internal microphone of a mobile phone (Samsung Google Galaxy Nexus). The Adaptive Leveler will apply dynamic range compression, will amplify quiet speech and balance the volume between music and speech. Furthermore, our Dynamic Denoiser will remove background noise and breathing, but will keep music segments.
The second example file is a conference recording with a video
presentation including music, talks, and discussions.
The speakers have noticeable level differences, that are aligned by our Adaptive Leveler. Using our Dynamic Denoiser for this file, all stationary and non-stationary background noises are removed without deleting the background music of the record.
The third demonstration file is an excerpt of the Abenteuer Energiewende podcast at the Karlshochschule International University. The interview includes multiple speakers with noticeable level differences and background sounds.
The following example file is a report about the 30th Chaos Communication Congress in Freies Radio Blau Leipzig. It starts with a live conference recording containing overly loud music with bad encoding quality and continues with sections of loud speech (live conference recording) and quiet speech (studio recording, better quality).
