The sample As_062__D4_513-stereo.flac has swapped stereo channels and also doesn’t have loop info. I’d try to make it right but I’m yet to get myself an audio editor which allows to see RIFF smpl loop data and save it, to first look at all the good samples to decide how long to make a loop, and then to apply that, and I’m still not sure if it’d be okay in the end.

I checked As_062__D4_513-mono.flac and it doesn’t have loop data either. Probably this is the root cause, as stereo samples were generated from mono ones.

In the readme file, you write:

The stereo effect is a mild pitch-shift doubling to create a stereo image, applied in mid-side effect so that it cancels out when summed to mono.

How had it been done, precisely? I first thought about chorus, but chorus doesn’t usually sum to the original mono (I may misremember); also I thought about pitch-shifting side channel but there is zero in side channel for mono signal. Then if even one adds a pitch-shifted size channel, it’d be a good idea to pitch-shift mid channel the same in the other direction (to balance perceived pitch)—and then again it won’t sum to the original mono. At first I thought I understood at least an idea—now I think I have no clue at all.

I want to try to recreate this effect as live processing and save a bit of space on stereo samples. 😄 And just to experiment. (Though in my case I think mono summing to original isn’t essential at all, so I’ll probably just compare how chorus behaves.)

If you hold a key, the sound will be cut off after a while. Release seems to be not very smooth. (using Linuxsampler)
