Noise at sample start/stop - DrumBox - 27-02-21
[attachment=3]
hey everybody,
I got a problem with disturbing noise when a sample starts to play and when it stops.
This is just noticable when I´m playing quiet parts or when I´m using Headphones.
I recorded the behavior with the piano sound (SalamanderGrandPiano_adapted v2.2).
(...but it´s the same with every other sound.)
You can clearly hear a click at the beginning and in the end.
You can find file attached to this post.
I assume this depends on the hardware I´m using, so some Specs:
Rasperry Pi 2B
Hifiberry DAC+

Does anybody got an idea?
Cheers

Hi DrumBox,
I can't reproduce the click, but do notice some rumbling present in your sample. No clue yet.
I'm now testing with an el cheapo DAC which may cause rumbling, next week I can test with my HiFiBerry box.

Hi DrumBox,
With a quality DAC it can be heard, in other words: I can hear it too with my production box.
The behaviour revived memory; it appears exact the same thing was reported a year ago but we left as being too small (and he had more pressing requests..).
What I notice:
- It's only at sound end, I don't hear it in the beginning
- It's hardly noticable; you need to have a quality DAC and use headphone and/or set your amplifier too high for your neighbours
- It's only at sound end, notes-off go unnoticed when another sound is playing - no matter at how low volume.
My findings contradict with the old ("at every wav") and your report even adds "sample start".
The old report makes sense as he always uses mode=once.
For your new report I have no logical explanation as of yet.
Time for creative thinking, I'll put it on the issue list this time.
