Hello, I am pretty new to game audio, and I am trying to make an ambient loop.
I am wondering, to make a seemless loop from a stereo file, is it standard to: have 3 files (intro, middle , and end loops?) or to have just one file which begins without a zero crossing with the understanding that whoever implements the file will start and stop the thing with fades?
I am using midi, and a method where you basically repeat the sequence 3 times and use just the middle for a seamless loop. However since the piece has a drone-like sound, making a short fade at the beginning and end of the loop causes a drastic volume change and a pop/click (even with a really short fade, like 20 samples). It is a stereo file so there is no chance to get a zero crossing in both channels. It has a continuous volume sound, so a long fade makes the loop point very obvious.
I can get it to sound great if I don't worry about making a zero crossing. But is this a problem for people who will end up using the file?
BTW, I am planning to sell the track on licencing sites such as audiomicro or wherever. Not sure if that matters, but if I was working with a developer directly then I would just ask them what they wanted.
Thanks for any help!
