Help With Joining Two Tracks

Post by jaybird8521 » Sun Apr 25, 2010 12:33 am

I have an audio cd of seamless meditation music that is broken up into 4 tracks. When played through a cd player, the tracks blend into each other to create a full hour of seamless music.

I am trying to add these tracks as background music to a recording I made with audacity, but I cant get the 4 cd tracks to join together without popping. I've tried trimming them as much as possible while zooming in all the way, but no matter how I join them, I keep getting pops where one track ends and the next begins.

Im sure there's a way to join them properly. Can someone please walk me through the steps? Thanks!

do you have dc offset?
remove it.

tell us how you are doing all this.
have you tried to put silence in the space where you get the pop?
do you still have dc offset?
remove it.

Im not sure what cd ofset is. If it's a plugin, I dont think I ever installed it.

I was originally using 1.2 but I just upgraded to 1.3 and I still cant seem to fix the problem.

I tried sliding the tracks together with the time tool, I tried deleting all the space between the two tracks so they touched each other perfectly in the timeline, I tried overlapping them and I tried using silence on the pop. No matter what I try, I keep getting a crackling noise where the two tracks join.

dc not cd
its an offset voltage in the wave forms
if you try to patch them there will be a jump if there is offset
use normalise to remove the offset

Tried normalize. It made the part I highlighted much louder than the rest of the track.

The most simple method is to use the "Fade in/out" effects so that each piece has a short fade-in at the beginning and a short fade-out at the end.
If you need the tracks to blend from one into the next you can use the "Time Shift tool" (double headed arrow) to adjust the left/right position of the tracks so that the faded regions overlap.

Here's a picture to illustrate.

Shout out if you need a more detailed step-by-step description, or if this does not provide what you need.


By the way, how did you get the tracks from the CD into Audacity?
