sonar sample rate problems in pro tools

Posted: Mon Jul 14, 2008 5:21 pm

I'm trying to complete a project i started a few years back in a friends home studio. cake walk was the program. the band broke up. the files were converted to wav and sent to me marked 48 khz 24 bit. I went to a pro tools studio to get started again and the tracks are sped up. The house engineer said there was nothing he could do on his end and that the problem occurred when the file was burned to disk. he suggested going back to the source and fire wire to a hard drive. Is this correct or is there a sample rate conversion that can be done. If i don't have access to the original .... am i done?
I know nothing can anyone help.

Welcome to Recording.org

If the files are playing fast, maybe they are actually 44.1kHz not 48k. In Pro Tools 7.4 when you import audio you can click convert, and then check the SRC (sample rate conversion) check box and chose the source and destination sample rate. I was able to make it think a 44.1kHz file was a 48k, so I don't see why it couldn't do it the other way.

To avoid any actual conversion, start a Pro Tools project with a rate of 44.1kHz, and import the files at 44.1 using the SRC option to force the rate. It will make a new copy of the files, but the digital data should be unchanged but with the correct sample rate.

Thanks Steve, I'll pass the info on. Don't you think this engineer should have known this...?... seems basic... and do you think I should look for another place to work?

From your description of the problem the answer seems simple enough, but maybe there is more to it then that. Can you email me the smallest of your files so that I can try to load it here? My email is gecko at geckomusicstudio dot com If it is not 44.1kHz audio labeled as 48kHz then elastic audio can band aid fix the problem, but in that case it would be better to get a copy of the original audio.

How close are you to Lowell MA? Very Happy

Look at one of the files on the disk in Windows Explorer. Right click, choose Properties, then the Summary tab at the top of the Properties window. Sample rate will be listed there.

Wonder what kind of machine/audio in/output was on the first recording box? Sonar doesn't have convert to wav because it records that way anyhow.
