I am getting increasingly more frustrated with this problem and I cant seem to find a solution. There doesn't seem to be much about this anywhere on here and I've tried to glean information from similar posts, to no avail.


The problem lies in whenever I try to import an audio file into Logic in which the audio appears to pitch down a semitone or two; the sample is the correct length in comparison to the tempo (which I have manually set to the original tempo of the file), the sample rate of the audio is the same as the project settings, I have turned follow tempo in the Inspector off, I've tried to use the time and pitch machine but it wont process and paste (it says that the audio is either follow tempo enabled or is an apple loop, I know that the file is a .wav), further more I have tried to use all of Logics inbuilt pitch adjustment tools but the outcome produces unwanted artifacts when played back (even with fine tuning and formant adjustment).


This is really annoying me it is not an isolated incident and it really gets in the way of productivity. I've looked for a way to contact a Logic Pro pro but it seems to be a dead end. So I was wondering if maybe someone else has shared this experience and hopefully if someone has found the solution?

    Sound like a broadcast wav (BWF) file with meta data. This type of file use the same .wav tag. Use a program such as Audiofinder to veiw the file, it will show if its BWF and if that is the case, use the conversion section of the program to strip the meta data ( which turns it back to basic wav file ) this may help.


    Also, Did you create the audio files your trying to import or are these files from sample libraries or from another project.

    Thanks for the rapid response. I downloaded the application which I have to say is very good. I dont think the file is a BWF but i've copied the 'Meta Data' bellow.


    The only thing I see that is out of place is that they are Acid Wave would conversion solve the problem? They are stems I have bought.

    I've the same problem and I don't know how to solve it. Everytime I import an audio file (aif) to a project in Logic Pro 9, its sound pitch down a semitone or two. I don't understand why...

    PB in the finder yields the same result?

    If not, then you might have a look in the Global Tracks chord section. Just a wild guess.

    The sample rate of the file MUST match the sample rate setting of the project. This sounds like a 44.1 vs 48 kHz mismatch.

    Either 1. set the project to match the sample rates of the audiofiles, or 2. convert the audiofiles to match the projects sample rate.
