I downloaded speex-1.2beta3-win32 binaries, and used the speexenc.exe and speexdec to process the file male.wav download from http://speex.org/samples I used both the narrowband and ultra-wideband mode: >speexenc -n --quality 3 male.wav n3.spx Encoding 8000 Hz audio using narrowband mode (mono) >speexdec n3.spx n3.wav Decoding 8000 Hz audio using narrowband mode (mono) Encoded with Speex

this is not really a development question, but i didn't find another mailing list to ask it. any idea why size of wav file doubles when it is encoded to speex and back to wav: $ ls -ls testi.wav 40 -rw-r--r-- 1 foo foo 40674 May 4 14:38 testi.wav $ speexenc --denoise --agc --quality 10 testi.wav testi.spx Encoding 8000 Hz audio using narrowband mode (mono) $ ls -ls testi.spx 20

Hello developers, I have a question about supported bitrates for SPEEX. Regardless of whether I specify a 10kbps or a 8kbps bitrate, the encoded .spx file is the same size and have the same PESQ value. This makes me wonder if SPEEX supports arbitrary bitrates, or only a certain set. A few more details about my configuration: I am using SPEEX encoder version 1.1.12 I am encoding a narrowband

Hi, We'd like to announce the first draft for the Speex RTP profile. It was written essentially by Greg Herlein, with some help from Simon Morlat and I. We'd like to get some feedback on it before it is sent to the IETF. Basically this will allow all SIP based VoIP applications using Speex to inter-operate. For those interested, there's already Simon's LinPhone (www.linphone.org)

I've checked to web for the format of the .spx file, and have not found anything complete. I've attached what I have deciphered so far. There are a few question marks in my tables that I want to understand better. I've also attached the .spx file that I used in the example values. I'm trying to take Speex-encoded data from an embedded microprocessor and put it into the .spx

In short try calling speex_encode_int and speex_decode_int. The calls to speex_encode and speex_decode expects the data to be a floating point values. The data is passed by pointer and the compiler does not do the conversion. This is why you are getting the segfault on decode as the short is 16-bits and a standard float is 32-bits.

Hi All, I'm very new to speex and in fact handling audio at all, it seems I have run in to a problem I seem unable to fix. I'm trying to take audio from a microphone using alsa, then encode it as speex and save to disk. I have been wondering if it has something to do with endian type, but speexenc and speexdec works fine. Currently I have the following setup: Platform:

Hi Tom, Thanks for your reply, I'm having a few difficulty's following you advise. You mention that I should be calling 'speex_encoder_int' & 'speex_decoder_int', I'm having problems finding these functions in the speex header. I am currenlty calling speex_encoder_init & speex_decoder_init in my test code, I have repeated the relevent bits of the example

I think your setup is wrong all the way. First, an uncompressed narrowband (8 kHz) file should take up 272 kB, not 1.43 MB. You're probably dealing with a 44.1 kHz file (you should downsample it first). Once encoded at quality 1, the result should take 8.5 kB, not 21 kB. As for the 92 kB, I have no idea where it may come from. Jean-Marc Le mar 03/02/2004 à 16:16, Rodrigo Parra M a

Ok here is something I couldn't see on the description page. We need to convert to 8 bit audio right? I'm assuming narrow band is 8 KHz 8 bit. Wide band is 16 KHz 8 bit. UW band is 32 KHz 8 bit audio?

Hi, I am working with libspeex api. I would like compare the size of speex file encoded with libspeex and the size of speex file encoded with speexenc. For example, I encode with speexenc (narrowband, quality 1) a wav file of 1.43 MB (17 seconds) output a spx file weight 21KB, for other hand I encode with libspeex the same wav file with same characteristics in arm processor, pocket pc and the

Hi, I am new to speex and I am trying to use the sample program given in the speex document. I have made some modification to that sample, so that input can be read from a file and the output can be re-directed to the file. I tried to encode an audio file using the sampleenc and decode the same by sampledec.c I am able to do it successfully, but when i try to play the output file from the

Is there a bugzilla or similar for speex?

I'm doing some work where narrowband speex audio capture is happening and being written to file in the ogg container format. Later retrieval for reading will occur too. I've been using liboggz to do the file reading and writing and have obviously come across some things I don't seem to follow or have just got wrong. I can happily generate an ogg file using liboggz with some test

Well, you seem to be using FRAME_SIZE but only defining frame_size. Otherwise, the code looks OK, but it's always hard to tell. I suggest you start from speexenc/speexdec or from the example I wrote in the manual at: http://www.speex.org/manual/node12.html Jean-Marc Le ven 19/12/2003 à 05:22, Fabio a écrit : > Hi > i'm developing a sort of VoIP application > for my

Please consider using 16-bit 16kHz (wideband) instead. It's a huge increase in audio quality and the bitrate is still very low, especially if you take advantage of Speex features such as VBR. 8kHz seems totally inappropriate to me for desktop streaming audio, let alone 8-bit samples. Or perhaps your recording equipment is an original Sound Blaster from 1989? (Even that could record at
