The way to deal with this in real-time is to fade in for a short period at the
start, and fade out at the end. In order for that to respond in real time, I've
found a good way is to delay the audio stream by a tiny value (e.g. 5ms) then
fade the audio at 5ms - 1 audio block (about 1.46ms). That way, when you hit
"stop" on the sample playback object (e.g. tabread4~ or xgroove~) the audio
stops, but the 5ms delay means that the fadeout starting at that moment will
happen before the audio you hear stops (because it is delayed by 5ms).
I hope that makes sense. Patch enclosed!
