[Vorbis-dev] RE: Vorbis decoder sample code

[Asheesh Vashishtha]

Hello all,

I'm trying to create Vorbis tremor decoder using tremor library, but the example I'm following is of the code 
written in oggdec.c.
However in tremor files, I also found a ivorbisfile_example.c file as well.

There is quite a bit of difference in the implementation of the 2 decoders I believe. 
I'm not sure about this since I'm just getting started with it.
Please help as I'm not able to compile the oggdec sample with tremor library.
is oggdec based on libvorbis, and the other example based on tremor library?
Am I doing something wrong? Any help would be deeply appreciated?

I'm using eVC++ 4.0 to compile the vorbis decoder for Pocket PC. 

Regards,
Asheesh

Thanks for your reply, Paul, but I've already ported Speex onto PocketPC platform but considering that my earlier files were
in mp3 the audio quality is ok but not comparable to that of mp3. Vorbis is even better at lower bitrates w.r.t mp3, 
which is why I'd like to try vorbis as well. If it sounds better than Speex than I'd go in for vorbis.

Moreover, there are portions of Speex which are still perform floating point operations while tremor is a completely fixed point implementation, so would like to go for that.
Can you help me in providing the source code for that.

Thanks &regards,
Asheesh

You may want to take a look at Speex.  It has the same type of licensing as 
Vorbis but is designed specifically to encode human speech where as Vorbis 
is a more general audio encoder.
