can't make audio.pitch to work...

Hi
I try to use the pitch parameter in unity iPhone 1.7 with the following code:

Code (csharp):

1.  
2. function Update () {
3.     Debug.Log(audio.pitch);
4.     audio.pitch+=0.01;
5. }

I attached it to an audiosoruce object, the sound is a stereo wave file, uncompressed, 44.1kHz, 16 bit. But the sound is not shifted in pitch. What do I do wrong? Thanks for the help!

have you tried it with a mono wav file?

 

I would never change a value in Update without multiplying it by Time.deltaTime to make it frame rate independent. But I doubt that would lead to your problem.

 

generally, yes. Though you might use something like for certain effects:

Code (csharp):

1. audio.pitch = transform.position.y*0.1

Regarding the problem, please try a MONO wav file and see if the problem persists. I know MP3 pitching is not possible, but not sure about stereo wavs - have a feeling it may only work in mono, but cannot check right now.

 

I found out that it doesn't work on the emulator. i.e., when using Unity Remote, the sound pitch doesn't change. But it works fine on the built. I think it is a bug. Thanks for your help!

Ah, ok. I never use Remote (I add an extra keyboard+mouse control script to all my iPhone projects so I can just play the build by running it in the editor - great for quick testing).
