I can confirm this.

On the background I hear a 50 Hz humming sound. It typically occurs when a microphone is not correctly connected to an amplifier or recording device. It's also the 50 Hz from the electricity grid. This can only be corrected by recording the sound again. Although ... somebody could try to filter the 50 Hz away, but recording it again probably gives a better result.

From time to time I'm on stage myself. I can re-record it when I have a performance again, but that may take a while. Right now everything is postponed.

Because I can confirm it, I set the status to "new". Because I can pick it up, I assigned it to me. (But feel free to take it over from me if you think you can do it faster.)

PS: 
- I'm not a developer. I'm a user myself and I submitted a few bug reports. I'm trying to confirm the bugs that other people reported here.

In this audio I uploaded now I reduced the background noise, and also apply a Comprsor effect. Please check if is better.
