Weird issue with Reaper and "gluing" audio

[shponglefan]

I should also add that I did not do any cross-fading when I copy-pasted the second loop and glued them together.

Anytime there's an abrupt start or stop to audio signal that forces an 'instant' transition from -inf dB (silence) to audio signal, or vice versa, you'll get a 'pop' of the magnitude of the audio signal. It's the 'ultimate' transient, in a sense, a vertical line.

You can eliminate the pop by fading up from -inf dB to the full signal (or fading down in the case of cutting to silence) or, in other situations, by crossfading that signal with another.


In the case of your edited loop, I'd assume that your butt splice (loop end to loop beginning) had a small enough abrupt transition that whatever pop there was was not heard.
