Compile/Build Speex on iPhone
The off dependencies are only for speexenc and speexdec, as far as I
recall.
If you omit those targets, you shouldn't have the ogg dependency issues.

Help decompressing Speex audio
I have an audio file compressed by JSpeex that I'm trying to decompress on the iPhone. I've been trying to work from the speexdec example in an attempt to port the core logic to ObjC. I have a class that does the decode and passes the result back to another class. (currently the other class is a unit test.) My other class is writing the converted output to disk. I compare the results of my

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

Encoding a wave file with a bad header
If I use Speex, JSpeex actually, to compress an otherwise valid wave file with zero lengths in the header would it impact the compression at all? Here's what I'm doing during compression in Java:
AudioFormat wavFormat = ais.getFormat();
AudioFormat speexFormat =
new AudioFormat(SpeexEncoding.SPEEX_Q5,
wavFormat.getSampleRate(),

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

Speex development
Essentially, the thing that's been holding up 1.2 was the AEC and
preprocessor. The codec itself is pretty stable and I do not really see
more work happening on it. As for the AEC and preprocessor, these are
really open-ended project and I lack sufficient time to take care of them.

Down Convertion from 32Khz to 16Khz
hi
on my device i can sample only at 32khz and want to use speex at 16khz so i
need to down-convert the input signal by factor of 2.
does anyone provide me a reference to some code that does that? are there
any trick to do that?
i tried to add to subsequent sample but the result was very bad.
what are the requrment from a decimation filter for audio?
thanks,

Decode file written from JSpeex using C/C++ API?
I'm new to Speex and I'm trying to compress audio using JSpeex in a servlet then play it back on the iPhone. I've managed to get Speex to compile on the iPhone by copying the speex and libspeex folders into XCode. I've read the sample code and the PDF documentation and I have a rough idea how to decode a raw stream. (I'm assuming the sampledec source works with raw speex audio

How to compile speex with XCode (for iPhone App)?
Hi,
I'm currently trying to use Speex on the iPhone but have some difficulties to get Speex compiled with XCode. Unfortunately I'm very new to XCode and it would be great if someone could give me a hint what the problem is.
Here is what I did in detail:
1. Downloaded the Source Code speex-1.2rc1.tar.gz from www.speex.org
2. Start Xcode 3.1.4
3. File > New Project ...

Problem with VAD in preprocessor on iPhone
Hello,
I am attempting to use Speex in an iPhone application and running into an
issue. I got speex to compile by following these instructions:
http://codeforfun.wordpress.com/2010/04/29/compile-speex-for-iphone/
Next, I was able to record some audio and play it back. I then inserted a
call to the speex preprocessor and am passing all of the audio buffers I
receive from Audio Queue Services

SPEEX on iPhone ?
I can confirm that it will run in real time on iPhone if you compile
with FIXED_POINT defined; it will also run in real time if you have
FLOATING_POINT defined and disable 'Compile for Thumb' in the target's
build settings in xcode. Wideband works too.
Cheers,

SPEEX on iPhone ?
Why don't you just try it?
From what others have been reporting, it shouldn't take you long to
get it running.
You can use speexenc and speexdec for testing.

SPEEX on iPhone ?
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

SPEEX on iPhone ?
ok, interesting !
Do you know how much CPU it takes for a real time encoding/decoding ? it's
more around 20% or 80% instead ?
Do you know if it works for 44100 Hz / 32kbps / Quality =8 ?
thanks again.
Vincent

Down Convertion from 32Khz to 16Khz
I've done something similar in Groovy/Java using Wave files. In my case I was downsampling from 16bit to 8bit. Here's the core of my conversion logic.
def convertData(def inputStream, def outputStream) {
boolean otherByte = false
inputStream.eachByte {
if(otherByte) {
//invert high order byte
int inverted = ((int)it) ^ 0x00000080

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
