Speex dev - Apr 2010 - Simple example of decoding streaming audio realtime?

Hi,

I'm new to Speex and a little uncomfortable in C programming. I'm
looking for a simple example of how I'd use Speex to decode a speex file
read off of an network stream and pass the decoded samples to an audio player. I
have speex running in an iPhone project and I started digging thru the
speexdec.c example trying to refactor as I made sense of the API calls. The
example is a little cryptic and involved and I was wondering if there was a
watered down version or if someone could whip one up for me. Thanx in advance!

Hi,

you could try using libfishsound and liboggz, like in this sample
decoder from the libfishsound source:

cheers,

Conrad.

Let me get this straight: you're a software engineer (by your .sig),
you're uncomfortable in C, and you want someone to write your code for
you?

Incredible.

I'm a software engineer. I'm terribly uncomfortable with C. I want
someone to show me a simplified use of Speex decoding. FWIW I'm finally
getting my head around the API but the example had me a little lost with its
cryptic variable names and monolithic nature. The example I'm asking for is
way simpler than the final code I will ship to production so in essence, I'm
looking for a how-to or head start. I can pick up and run once I know which
pieces do what. That may not have been clear from my earlier email.

Conrad,

That's exactly what I was looking for. I just got finish trying several
attempts at porting libfishsound to XCode/CocoaTouch land but am facing
dependency issues on the other xiph libraries. (liboggz, libvorbis, libflac,
etc.) Rest assured I know what the issues are and how to address them. I am at a
fork here. I can either port the bulk of the xiph libraries to XCode or continue
on my original path trying to get just Speex and libogg running and with my
original progress either approach appears equal in terms of effort. I should
also add that my original comment, being uncomfortable with C, really applies to
more than just C. I'm uncomfortable with everything that goes along with
C... the configure scripts, the make files, the dependency resolution. What
I'm really looking for is somebody who has taken the battle scars and
trail-blazed a path into XCode/CocoaTouch. At any rate I appreciate your help.
Thanks again.
