...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 ?

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.

...hony protocol) to some embedded systems. I require to run speex in an environment that doesn't support memory allocations. How difficult is it to convert speex_encoder_init and speex_decoder_init to use preallocated memory buffers (presumably passed by the initilisatio functions themselves)? - farhan - farhan -----Original Message----- From: speex-dev-bounces@xiph.org [mailto:speex-dev-bounces@xiph.org] On Behalf Of Gervase Markham Sent: Wednesday, June 28, 2006 2:55 AM To: Jean-Marc Valin Cc: speex Subject: Re: [Speex-dev] Library split (poll) Jean-Marc Valin wrote: > In the 1.1.x branc...

Hello, first of all, sorry for the joke in the subject ;-) I have successfully update the speex library my software was using from 1.1.12 to 1.2beta1 (1.1.13). It is a VoIP software, where i set preprocessor VAD on and use the result of speex_preprocess() to determine if there is voice activity. I must say that it works fine...since i have update to the new version. Ive been testing, and

how many calls can I make to speex_encode_int before calling speex_bits_write? Can I stuff 10 frames? - farhan

hello all, At my workplace, our colleague Mukesh has just completed a port of speex 1.2.1 to Palm OS. He had to write a couple of mathlib functions, but the trunk remains unchanged. It works quite well, I was wondering if there will be any interest in this port in the distribution. - farhan

...ally fast arm cpu (and speex works in realtime on even the 201mhz arm cpus). while compiling, remember to define the fixed-support support and you are all set. narrow band (8khz) and 8kbps bitrate will work very well. while you are at it, pse send the xcode project file to include in the tarball. - farhan On 11/10/08, Vincent Burel <vincent.burel at vb-audio.com> wrote: > 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...

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, Dave

Hi Farhan, It is interesting that GPRS is 9.6 kps, as per GPRS standard it should be 115kps ? if it is 9.6kps is true then I would use speex codec on GPRS for my project, since in some country they charge GPRS on flat rate rather than expensive airtime.

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

Hi, Can you please share the standard document of Speex codec. I have the api doc and speex manual but it doesnt have the details about the mode of operation and bitrate details etc., So can u please give us those details.
