Hi, guys,
I am a newbie to digital audio programming and completely have no
idea on how to use Audio Queue, With the XCode documentations, I had
implemented play, pause, stop with Audio Queue, but now I have to
implement the fast forward/rewind with Audio Queue APIs, can anybody
tell me how to do it?
I had searched Google and this mailing list, but I cannot find any
correct solution for fast forward/rewind.
Here is what I am gonna do:
a. I have a CAF file, and a meta-data file which indicate the start
time and the end time of each pieces in the CAF file.
b. When user press a play button, I need to play the CAF file.[I had
it done.]
c. When user press a pause button, I need to pause the CAF file.[it
also had been done.]
d. When user press a fast forward button, I need to play the CAF at
the time which is specified by the meta-data file, untill the file
reaches the end.
e. When user press a rewind button, I need to play to the previous
time specified by the meta-data.
Now, how can I implement it?
Thanks in advance.
Tonny Xu
