similar to: Simple example of decoding streaming audio realtime?

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

Different engineers have different skill levels, so what. If someone asks for some help with the reference implementation the least we can do is point them in a useful direction. If

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

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

Also here are a few other bitrate-related questions: 1. Does average bitrate mode ==> variable bitrate mode? 2.

Hi Randy, thanks for the reply. So, suppose I encode an audio buffer (8000 kHz, MONO, float) of 640 PCM frames. In output I have 4 speex frame of 20 byte

Adobe's "SWF File Format Specification, Version 10" supposedly allows a speex-encoded stream to be wrapped in a .swf file as a sound stream, however, I have been unable to find an example of such a file anywhere. Can someone please point me to such an example file? Note that I prefer speex encoded as a sound stream and NOT a sound event in order to reduce latency on playback at the

Hi Randy, Thanks for reply. I have one question though. While compiling the speex (downloaded from http://downloads.xiph.org/releases/speex/speex-1.2rc1.tar.gz), I gave ./configure -enable-ti-c55x option and then built the library through make and make install using cygwin. In this case, I get this error "error: member "bits.o" of archive

Hi, I am currently working on C5505 USB stick http://focus.ti.com/docs/toolsw/folders/print/tmdx5505ezdsp.html to sample input voice and encode it. For compiling and buring usual programs, I am using CCStudio 4.0. For encoding voice samples, I am using Speex codec binary http://downloads.xiph.org/releases/speex/speex-1.2beta3-win32.zip or

Nicer way: void* speexState = speex_encoder_init(&speex_wb_mode); int speexFrameSize, speexRate; speex_encoder_ctl(speexState, SPEEX_GET_FRAME_SIZE, &speexFrameSize); speex_encoder_ctl(speexState, SPEEX_GET_SAMPLING_RATE, &speexRate); SpeexPreprocessState* speexPreprocessState = speex_preprocess_state_init(speexFrameSize, speexRate); Jozsef -----Original Message----- From: Max

Hi, in a VoIP application, the endpoint A send speex payload to B. B doesn't know how A acquire audio, it only know that the channel is narrowband so, how can B know the size of the output buffer to pass to the speex_decode()? Thanks, Daniele.

Hi all, has anyone ever tested the speex source on a 64bit OS. I am interested if the source is ready for x64 platforms.
