Well, wav's are considered little endian but for raw files, there's a

Hi, I had a similar question ... is the endian-ness of the encoded speex file, system dependent? or is it always little endian? If it's always little endian (like the header seems to be) then big endian machines (or java) will need to map everything to bigendian before decoding ... thanks in advance, Kaveh. <p>Ben Stanley wrote: > Hi, > > I got my hands on the LCA

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, I am experiencing some unfortunate problems when encoding WAV files to spx using version 1.0.4. A "click" which is not present in the original WAV file is added to the end of the spx file. Is this a known problem, and if so, which version of the encoder should I switch to... and if I have to switch the encoder, will I also have to switch the version of the decoder? Sincerely,

Would it help if I scale the input wav data before encoding to spx? One interesting thing is if I encode the same wav file to spx(or decode the same spx file to wav ) on Windows platform, then there is no such big clicking noise, samething is true if I use floating_point speex library to encode/decode on WM2003. Problem happens only on WM2003 using FIXED_POINT library. Thanks Yanxin -----

Hi! I'm looking for a documentation of the .spx file type? I want/need to know how such a .spx file is built up. I want to create a .wav to .spx converter. And additionally a .spx player. I already searched the net and the speex site but I couldn't find anything useful. Maybe I'm missing something? Thanks for your help! Best regards, Peter -- Neu: GMX FreeDSL Komplettanschluss mit

Dear experts, I am trying to understand the structure of the Speex .spx file, so I can packetize each frame in one packet for example, and in the receiving end, I can decode a file that has all the received frames (some of them may lost). I tried to figure out what is the delimiter used to separate the frames but I could not so far. I also tried to deleted some data from the .spx file or change

I have problem with coding and decoding. I record voice from mic coding and write to file. And when I read from file and put it on sound card it's terrible sound.

Hi there. We're trying to build a speex decoder for Palm OS (i.e. ARM7). No major problems porting thus far, but when compiling the speex modules with -DFIXED_POINT all the silent parts of the output are replaced with what sounds like high-power white noise. The spoken parts sound great, but all the silent parts in between speaking just sounds like white noise. We're using speex 1.1.6,

It seems that with the file I posted, the decode noise persists all the way back to 1.1.1, when using --enable-fixed-point. When we configure with --enable-fixed-point-debug, the decode seems to be correct, even on 1.1.6. Hope this helps, and thanks for your time!

Hi all, I've built Speex 1.03 on Mac OS X. I encoded a raw PCM file successfully using: /usr/local/bin/speexenc raw_samples.raw --rate 44100 --be --16bit raw_enc.spx Warning: Speex is only optimized for 8, 16 and 32 kHz. It will still work at 44100 Hz but your mileage may vary Encoding 44100 Hz audio using ultra-wideband (sub-band CELP) mode (mono) If I decode to .wav, it works fine.

Hi, With the talk of speex possibly mis-behaving on PPC, I decided to check the big-endian architecture I have handy - the Ultrasparc. - playback of Intel platform .spx files appears fine on the Ultra 10. - encoding a .wav file and playing back on the Ultra 10 worked too. My evaluation is that it works the same on my Ultra 10 as it did on my Intel laptop. But I must say the evaluation was made

Hello, I encode a file with speex so i get a .spx file but i want to decode the same file i get only one second of my file and nothing Some idea why?

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

Dear Speex codec community: I am working on conversion of voice files. I could not figure out how to use speexdec.exe 1.2.3 in piped mode in order to avoid the creation of the potentially large intermediate *.wav or *.pcm files. Any pointer to web or file of instruction is appreciated. Attempt (one long command line, failed): type d:\test.spx | "d:\speex 1.2.3\bin\speexdec.exe" - -

Can you post the input and output file on the web and specify what options you're using (use speexenc/speexdec, *not* your own code).
