To StarXing:
Thank you for your advise.I have tried,it make sense when I played a sine
wave and recorded it. But when I played a mp3 or wma file (a song),it
distortion very seriously when sample rate is 22050 or 8000,and sound good when
sample rate is 48000 or 44100 or higher.My question is: when playing a song(mp3
or wma),does it realy distortion when I change its sample rate?
Actually, I wonder what does DataRangeIntersection mean, could you tell me
more?
Thank you!
Best wishes!
Neil

Maybe you should also change DataRangeIntersection accordingly.

Hello,
Actually, I just want to set a default sample rate, to in accordance
with my product.What can I do?
Thank you all!

Hi,I have changed them as a same value 22050,like this:
MIN_SAMPLE_RATE 22050 // Min Sample Rate
MAX_SAMPLE_RATE 22050 // Max Sample Rate
But it doesn't work.
When I change sample rate in the 'SetFormat', only the header
changed, when play a wav file, it is very slow of very fast.
Si Gang <sigangllj@xxxxxxxxx> 写道：
Hi,
Maybe you can search MIN_SAMPLE_RATE and
MAX_SAMPLE_RATE in your code and modify them as follows.
#define
MIN_SAMPLE_RATE 8000 // Min Sample Rate
#define
MAX_SAMPLE_RATE 96000 // Max Sample Rate
Best wishes
Gaby
