Speex dev - Nov 2008 - SPEEX on iPhone ?

hello,

i 've already used SPEEX in a protoype of voip application (on VC 6) and i
must says that it works well, the sound is good, and the object works well
with multi-instances.

But now i'm wondering if it's possible to port the SPEEX encoder (and
decoder process) on iPhone ? Does someone tried to do that ?
Do you think it is possible or completly over the capabilities of the ARM
processor of the iPhone ?

Thanks by advance for your reply.

vincent,
someone in our team did compile it on iphone. he didn'y any particular
problems. the arm specific optimizations are not necessary given
iphone's fast cpu.
just add all the speex sources to xcode's project pane and compile it.

Hello Ashhar,

thanks for your reply, but i'm a bit surprised.

1- Does it mean that it is possible to make a Real Time Encoding/Decoding
with SPEEX on iPhone ?

2- What parameters have been used (QUALITY, SAMPLING_RATE, BITRATE) ? and
what kind of CPU load do they measure for that ?

Thanks by advance,
Vincent
