Change tempo of entire song
Okay guys, got another one for you(se). We recorded a cover of Los Lonely Boys, but it seems about 5 BPM too slow. We've attempted a number of times to speed the entire song up. We've tried it through the insert tempo groove clip looping option, and the tempo list / view process. it seems to change tempo on one or a few tracks bit some not. On playback you can hear that the timing changed for only one or a few tracks but not all, so there becomes out of timing tracks. We've tried the "select all" method of selecting all of the tracks then applying insert tempo change with the same results; plus it takes forever for the computer to go through each clip. Any thoughts? Thx again, J

Think laterally.
Mix it down as it is to a 44.1Khz file. Then, take the two track wave and stick that into a wave editor like Soundforge, Audacity , etc, and set the sample rate to 48KHz without resampling. Then set it to 44.1Khz again but this time choose to resample.
That will speed it up by about 8 percent.

Yeah, but let's face it, Scott, Audio Snap can do some severe damage to your audio, particularly bass lines, no matter which rendering method you choose. If you're going to try it, make sure that you have a backup of your original file.

First, make sure you have only the one tempo entry at 1:01:000 in the tempo view. If there are redundant entries elsewhere in the project, delete them all. Ctrl-A to Select All, open the Audiosnap palette (sorry my shortcut is non-default), set the Clip Follows Project mode to Autostretch in the dropdown to the right if the button, and then click the button. You should see red arrows show up in the upper left corner of every clip, indicating that Autostretch is enabled on them (small clips may not display the arrow if you're zoomed out to see the whole project). Now change the project tempo in the Transport module of the Control Bar. Audition it, and see how it sounds. If there are no sync problems, Bounce everything to Clips, and listen again to see what you've got. Note that some FX can get weird with Autostretch working in real-time; you might want to bypass all FX until after you've bounced the clips down. I recommend doing this all with a copy of the project, since Audiosnap changes cannot be reversed after bouncing and saving. And you may want to experiment with bouncing individual clips and groups of clips with the stretching algorithm in AS options set appropriately for the type of material in each clip to get the best possible results.

If the song is not finished - finish it! Once it is finished - mix it! 5BPM is not going to effect your mixing ability on the song.
Now with a two track mix try Paul Russels suggestion, or import the two track into a new project and try Scott Garrigus' suggestion.
Why go through the efforts to change all the tracks, then find that 5BPM faster was too much? Or too little?
It's a lot easier to work non-destructively with a two track mix!
Don't fix it in the mix ... Fix it in the take!

Thanx Paul, Scott, Brundle & Coda. The two track idea sounds pretty simple. I'll give it a shot. I think I'll use "Save As" and try it out on the test song since we're still tweaking it. Thx, j

First, grid the song out either with the Set Beat/Measure at now or hand drawing the tempo map adjusting as you go. Both take practice, but after a few hundred or so you'll be doin as good as me at it. Secondly, once the song is gridded out, Then tell the audio clip(s) to Follow Project tempo in the Snap Audio pallete. After telling them to follow, Change or redraw the tempo to your hearts desire. (5 beats or so faster in your case) Cool thing here is now you can tell It what to do. Lastly, you might re-bounce the audio clip so as not to hear the online processing. set offline processing to advanced for polyphonic material. I do this with originals all off the time, then change keys, tempos, or sometimes borrow their tempo map to preserve a feeling or experience. Hope I helped!
