1. Re: CS4 audio pitch shifter shifts audio track in time (not just pitch)?
JSS1138 Oct 4, 2010 9:33 AM (in response to avpromedia)Just out of curiosity, why would you apply an effect that does nothing?
The proper issues here are:
1. Do you get the same result when the effect is actually used?
2. Is it supposed to work that way?

So I can narrow down the problem and make it easier for other people to test.
The result is the same when I shift the pitch for real. And of course it should not work that way.

3. Re: CS4 audio pitch shifter shifts audio track in time (not just pitch)?
Stan Jones Oct 5, 2010 9:13 PM (in response to avpromedia)I'm next to my CS4 setup, so I did the test here.
I created a 30 second tones and bars clip, dropped in in twice. (V1/A1 and V2/A2). Put pitch shifter on A1. FormantPreserve is on by default.
Silenced A2; exported A1, then did reverse.
Imported back in and put on A3 and A4. Dropped to frame level; I see no difference.
I also switched to audio units. Did not see difference there either.

avpromedia Oct 5, 2010 10:53 PM (in response to Stan Jones)You're right!
Further test shows that the audio sequence's sampling rate need to be changed to 44.1Khz to trigger this.
So, do the same test you did with these changes:
when you create the sequence, change the audio sequence's sampling rate from the default 48Khz to 44.1Khz
When you create the bars and tone, also change the sampling rate to 44.1 (although this may not be necessary)
When you export, also change the output audio sampling to 44.1
Thanks for helping.
