white noise test
I think there is a small fade in when LinuxSampler plays a sample.
I only notice that if I play samples that have distinctive sound like frame drums: the very first part of the sample (i.e. the sound of the finger hitting the skin) is not audible, but if I play that file in Audacity I can hear it correctly.
I made a test recording white noise from LinuxSampler and I take a screenshot that shows the 1~2ms fade in.
I tried .sfz solutions with a one second of white noise:
<region> sample=./1sNoise.wav key=36 loopmode=one_shot
<region> sample=./1sNoise.wav key=37 loopmode=one_shot ampeg_attack=0
and another one with a one second of silence + one second of white noise:
<region> sample=./1sSilence-1sNoise.wav key=39 offset=44100 loopmode=one_shot
with same result.
Can you confirm this? Is this editable?
Looks like a bug in the SFZ engine that just recently had been fixed. Checkout the latest SVN version of LinuxSampler, which should fix this issue for you. For more details have a look at the following discussion about this issue on the mailing list:
Please note that as I pointed out in my last messages of that mailing list thread, there might still be SFZ files where this bug could still be encountered. At least from what I see from the SFZ engine code: Specifically if there are volume modulators defined in the SFZ file which shall become active after a certain delay. If you stumble over one of such cases let me know!
I am closing this report now. If you still think this is an issue that should be resolved, then feel free to reopen this report. Thanks!
