Hello:
I'm considering writing a program which needs to work with sound files
(aiff and mp3). I am examining my options to determine what would work
best for me. The three options I'm looking at are Java, CoreAudio, and
OpenAL.
Here are the operations I want to be able to perform:
- play
- pause/stop
- jump to a particular location in the song
- loop a section of the song
- be able to slow down the play back of the song without changing the
pitch. This is the most important part.
- work with mp3 and aiff files. If only one of those options is
available, then I would prefer mp3.
I would preferably like to be able to port this program to as many
platforms as possible (Mac OS Classic and X at this time), but if the
best solution for me at this time is limited to Mac OS X, that will be
OK, too.
I would like some feedback on what my options are, and if the CoreAudio
API can perform what I need to do. I have very little CoreAudio
exposure and experience, so I'm trying to get a feel if this is the
best way for me to go. My Mac OS X experience lays more with Cocoa,
and not Carbon.
