Extremely frustrating tempo issue in SONAR 8.5 Producer

Hey all

I've been doing home recording with various SONAR editions for 6 years now, but this was a brand new problem for me:

When I finish mixing and export it to a wav file, I usually import this into a separate SONAR project for some rudimentary mastering, such as Waves limiter plugins and the like. This time a friend of mine (who's only just begun recording at home) mailed me a wav for me to "master". When I imported it, I noticed that the track tempo setting in SONAR (default: 120 bpm) changed the tempo of the track I imported, stretching it unnaturally and making it sound crap. 

Never ever encountered this problem before! So... to check I tried to import some old master mixes of mine into this very same mastering project: no tempo problems. The tempo of the track did not affect them. Checked the sampling rate of my friend's track, but no problems there. It was 24 bit and 44.1 as all my own mixes. So I have no idea why only this particular wav gets its tempo messed up but not the others I've "mastered". Any suggestions? I know he recorded it and exported it in FL Studio 9 - but this can't be a problem, right?

Thanks for your reply. Will check that ut asap. 

Before posting I did try to import another, older wav file into the very same project. This older wav wasn't at all affected tempo wise, whereas this new FL 9 wav slowed down or speeded up as I tweaked the track tempo. I also asked my pal for the bpm, still didn't sound right as I set it to 132 bpm. Normally that tempo meter only affects MIDI.

This sounds like a clock speed issue. (Where the sound card's clock does not match the project) Any way to double check that?

You are correct about the tempo has absolutely no influence on audio. I think DAve is onto the problem.. it must be some different format that does have tempo, but, one would think if that was the case it would force Sonars tempo to 132 automatically.

It's more likely that Sonar would keep it's tempo and alter the clips tempo. Otherwise, every audio clip that you add that had tempo data would force Sonar to change the song tempo resulting in a mess. Especially for people who like loops :-)

Thanks so much for all the answers! Much needed, as I only know 0.01% of the technical stuff. 

Seems like you were right, SToons: audio looping was "enabled" on clip properties. Disabled it, and now it sounds right. Apparently FL 9's wav-maker thingy stored this info for SONAR to read...? Strange.

By default FL Studio is set to save tempo information in with the wave file as the program was originally created to make loops for producers.
Sounds like the problem has been solved.
