Contains a constant hiss at around 3800Hz
Drag and drop the sample in a track.
Put a high-pass filter at 3000Hz.
Put the Clip effect to amplify around 40dB.
Hear the hiss. I analyzed it using Audacity and its Spectrogram, since it's not simple to see this hiss in a Spectroscope such as LMMS Equalizer.


Tested in 1.2.1, but the file hasn't been changed since 2007, so pretty much every version ever.
If interested in using this sample right now, just drop in a Notch Filter at 3800Hz, with resonance 2 or above.

IMO this is a wontfix issue, as it will be irrelevant when the sample library is replaced.
Fixing the sample shouldn't be hard either, but it does technically break user projects.
Yeah, I'm just leaving this here for those that might be interested. I got this info from a subscriber from my channel who needed this sample.

Then do you mind if I close it? It will still show in searches for "bassdrum01" or when browsing closed issues.
