Hello! I would appreciate some help with an issue I’m having:
I have two or more music files, and I want to append one to the other so as to make a single file. It’s live music from the same performance. So imagine a band is playing live… they play song A and then song B, so I have “A.mp3” and “B.mp3” and I want to combine them into a single, seamless file.
The files start out as MP3 or MP4, but first I use iTunes to convert them to AIFF. Then I open the the AIFF files in Audacity.
I either cut audio and paste it to the end of another track, or I use “File → Import → Audio” followed by “Tracks → Align Tracks → Align End To End.”
Here is the issue: when listening to the result, not all the time, but sometimes I notice a small pop at what would be the border between tracks. I’d like to avoid this if possible. It seems odd to me, as it’s contiguous audio from the same performance. Maybe someone with more knowledge and experience can guess what’s going on. Perhaps it’s just a flaw in the audio itself?
I don’t know if this is relevant, but I’ve observed that if I zoom in very close at the border between tracks, I see a gap there. For example, here is a screenshot after I used “Align Tracks → Align End To End”:
This might not be relevant, thought, because I can see this gap between tracks even in cases where I don’t hear a pop.
If anyone can guess what’s going on and perhaps offer a workaround, I’d really appreciate it. Thank you!
