How do I speed up the tempo on a finished audio project?
Tutorials I've found for Audio-Snap are really ambiguous and vague, (mostly meant for those familiar with using the tool). All I want to do is speed up the tempo and export the entire finished project. Can anyone give me a brief tutorial or point me to one that shows me how?
Also, in doing this will it affect the overall quality of the project?

If you go to view>tempo then it will bring up a graphical representation of the entire project's tempo. You can then use the line tool to speed then entire thing up or click on the list button to edit each individual tempo event if you want. I am not familiar with a global way to raise the tempo of every event proportionately.

See this post in the X1 forum: http://forum.cakewalk.com/fb.ashx?m=2391045 Works the same way in 8.5 except for the method of enabling Audiosnap, which you can do form the AS palette, or by selecting the transient tool after selecting all tracks. And in your case, all you'll need to do is change the initial tempo.

I'm still not sure if I am making myself clear. The tempo/view way was easy enough to understand and allowed me to to apply and hear different tempos. But how can I permanently apply the tempo I chose and finalize the project for export? As for brundlefly's method.....I was completely lost. I only know how to bring up the Audio-snap palette on one track. But that's it. Can anyone walk me through this in how to do it in Sonar 7 PE? (think of me as a complete clueless noob). I've never ever used this tool.

brundlefly's method is the best way to change the tempo of a project where audio is already recorded. changing the tempo of the project does nothing to the audio itself. it will only stretch out the waveforms to fit the new tempo. MIDI is affected directly by the tempo of the project, however, so if you have MIDI and AUDIO in the project, changing the tempo of the project will get them out of sync unless you sync up the audio with the MIDI using audio snap. the only other method to change the tempo of the project would be to create groove clips out of each audio clip and manaully change the tempo for each clip. that would be more painful and less accurate than audio snap, IMO. this is what audio snap is for. I do not have time for a step by step tutorial of audio snap for you tho. however, I think there are some cakewalk videos on youtube which might help. search for cakewalk audio snap in youtube and you should be able to figure out how to do what you want.

First off thanks for you're reply Beagle. What youi wrote is exactly my point about those horrible videos. They are worthless for my simple call for help. I've gone through all of them. Some start out by saying it's a simple how to on changing the tempo, jump through without explaining the steps involved, and finally have you listen to the successful end leaving me with a blank stare. I have Audiosnap just don't know how to use it. From what you wrote Beagle, (that you don't have time for a tutorial), I'm understanding it as it's just way too complicated to even bother. I attemped brundlefly's method but there has to be something missing in his instructions since I can only get one bar of playback. Also there is no 'drop down' menu on my Audio snap palette, just icon buttons for what he mentioned. Niether is there an Edit filter for that matter, (maybe he means something else)? It's frustrating.

sorry you're frustrated with it. honestly I don't use it. I've tried using it a few times and finally determined that it was less aggrevation to me to re-track. I haven't even tried using since about S8 (I have 8.5 and X1 that I've never even tried audiosnap on). I have used it successfully on at least one project, but it was not easy. I had to manually line things up because it kept miscalculating where the transients were.
it's also possible that S7 doesn't have the same controls that brundlefly's instructions are talking about because I do know that audiodsnap changed drastically around 8.5, IIRC. and also, IIRC, audiosnap first became available in S7 (or was it S6?), so S7 has a very "young" audiosnap version and could very well be lacking in some key features.

I agree. But I am experimenting. I was listening to my projects and felt it would be cool to have em a little peppier for some listeners I know that are unconscious speed demons, (drummers in general and some pianist). I looked to my left and gazed at my old turntable. It has a pitch control and I remember I used to speed records up a litlle just to fit the time in a cassette. I wondered to myself if one could do this to a wave file just for the sake of those speed demons. I personally like music at a slow pace, (it swings more), but most I know like everything up-tempo.

Dreamer: Do you have Sony Soundforge or Sony CD Architect? There's a way to speed .wav files up or slow them down in there. I've used it so I could fit a collection of tunes on a cd that were over the Red Book time limit and it worked out fairly well. I didn't do any major changes so I don't know what the useable limits are. It doesn't change the pitch like the varispeed on your turntable.

☄ Helpful
Proud owner of Sonar 7 Producer Edition I overlooked what version of SONAR you're using. S7 uses Audiosnap 1.0, which has a dedicated Autostretch button in the AS palette - the double-ended arrow, fourth from the left. You just select all the tracks, and click it to enable Autostretch on all of them. After you change the initial tempo, SONAR will apply the stretching on playback in real time, and render it on export. The rendered stretching should sound better because SONAR can use more sophisticated algorithms - and different content-specific algorithms for different tracks - when it's not constrained by the demands of real-time playback. If you want to render the stretching permanent within the project, you can bounce the clips down in place. Just make sure you're working with a copy of the project because once you save it, it will be difficult to undo. That's about as detailed as I want to get. The information is all in the PDF Reference Guide. If you have specific questions about something in the Ref. Guide that is not making sense, I can help with that, but if you want a step-by-step recipe, I can't do that because it depends on the project. .

Was Process>Length mentioned already? You can shrink or stretch the audio in % neatly without artefacts as long as you don't go extreme.
SONAR PE 8.5.3, Asus P5B, 2,4 Ghz Dual Core, 4 Gb RAM, GF 7300, EMU 1820, Bluetube Pre - Kontakt4, Ozone, Addictive Drums, PSP Mixpack2, Melda Creative Pack, Melodyne Plugin etc. The benefit of being a middle aged amateur is the low number of years of frustration ahead of you.

Dude. Do you mean "Speed it up like on a turntable with pitch control"? Where the pitch goes up with the speed? If that is what you mean - JUST GET REAPER. It costs next to nothing and the speed control slider is right there front and center in the middle of the screen. Simple simple simple. Throw all your individual tracks in there - OR just your finished stereo mix - and joyride the speed slider. "IF" that is what you mean by speed it up.

Simply amazing Brundlefly. Yep that did it and wow!! Great results. The only problem I had was that when I exported the entire project, it took well over an hour to process 8-tracks into one wave file. I have an older computer with only 1.40Ghz of Pentium III processing power so that may be the cause of that. But anyway now I have one more great tool to fool around with.
Jackn2mpu, those programs you wrote about are probably pretty cool. But I'm a cheapskate and I live on a budget so buying more programs is not on my 'things to do' list.

Lol! Thanks bro...no more programs. I ain't buying anymore software. Dude I dig that avatar. I'm a Speed Racer fan to death.

try bouncing to tracks first. get them all "printed" then export.

Tried that too. My processor can manage anything Sonar throws at it reasonably quick but Audiosnap....that's a different story. Almost seems like grass grows quicker. Individually bouncing each track that has been Audio-snapped is a lesson in extreme patience. Makes no difference if one bounces the track individually or as an entire exported track. It took about as long either way, (and that's with fast bounce checked off in the 'bounce to track' menu).

Glad you found a solution, Audio snap is a huge processor suck, Rendering multi tracks will be slower. Like Beagle recomendedtry working with a Stereo master file next time it will be faster. I use Wave Lab and it seems to run in real time ( 3 min song takes 3 min to render) I have a old P4. This is a free download DJ software that's a heap of fun for applying real time stuff like time stretch and speed. One can always do a recording of "what you hear". http://www.virtualdj.com/
