...ibution and the TI's Code Composer Studio v3.1 simulator. I coosed speex_C64_test.pjt and modified the speex_C64_test.cmd to only use the DM642 external RAM memory. I'm not sure about the input file, the speex file and the output file formats. The README file refers that the input file is a headerless 16-bit stereo audio file, derived from the male.wav test file ( http://www.speex.org/samples/male.wav). Is it correct? Or is it a headerless 16-bit mono audio? How can i listen the output file? is there any player to play it? Or do i have to reconstruct its header and add it to the output file? How...

Hello, I've authored a tool based on clang's libtooling and wish to make its build process similar to LLVM's via cmake on multiple platforms. I'm primarily developing on Arch Linux (with the distribution-provided llvm) and also maintain OS X builds using the prebuilt library archive from llvm.org. The llvm packages for these platforms contain exactly what I expect: /lib,

Using Ices2, is it possible to take 2 mono sources that are presented to the soundcard as the left and right channel, and make each of them a seperate mount point? My sources are all low bandwidth mono, and I would love to have a second stream without having to add a second soundcard or a second machine. I looked through the documentation, but I don't recall seeing this specific ability.

...d=0002381 These include app_chanspy, the ability to spy on ANY bridged call taking place inside asterisk. NOT just ZAP as with ZapScan/Barge. Native format_* files being used for moh. Reload enabled res_musiconhold. format_mp3.c that produces SLNR output to asterisk, format_slinear.c for raw headerless audio, format_base65_wav_gsm.c aka wav49 held in a base64 containers(it can read and playback from these .b64 files) All this is thanks to my employer asterlink.com and anthm. So everyone please test and provide feedback. Thanks, Brian Asterlink.com PS: More to come at a later date.

They are all single source, single function, compilable headerless files extracted from open source repositories. They are grouped in folders, in a similar way the original project was. Q2: I read that using glob might not be a good idea, even though there is a partial workaround. However, when trying to understand what the other External suites were doing, I not...

...file stops and the next one starts. I guess this is something to do with headers. I get a small gap too with the vorbis equivalent [oggenc -> file then repeatedly pipe the file -> ezstream -> icecast ; so I've switched back to ices2/stdinpcm]. I even tried to hack oggenc to create headerless (no headers or bos flag) and tailless (no eos flag) ogg files, but these seemed to be ignored totally by ezstream or icecast - they pass through without being recognised (not sure which, sorry). So, before I go hacking further (I guess I should try headerless MP3 files), does anyone have any sugge...

Hi list! Just wondering, why is * sticking with an mpg123 version from the stoneage? Gentoo comes with 0.59s-r8 and this version doesn't even start. Ik know I could forcibly unmerge mpg123 and install the old version but I guess some day newer versions will have to be supported? Thanks!

Hi all, Here is the script i want to make - Caller call to a number to record a message - Asterisk answer and start recording message as following + User press * to start recording + Record is finished if: + User press # + OR message duration reach 60 second + Hangup How do you counting down 60s, and how to detect # (i make a test using Read() but it cant read #) Thanks in advance

...essors. The zip includes a readme file describing the changed and added files. I have done no assembly optimizations, just made working builds. I originally had a test audio file in here, but that made the zip much bigger. I used GoldWave to convert the sample files from the Speex website to headerless audio files. Note that this build includes a (selectable) manual memory allocation, which allows the user to allocate memory out of a fixed array, instead of using calloc. This improves visibility into the allocation process, making it easier to tune memory usage. Thanks to Jamey Hicks for t...

Hello list, it seems that Asterisk is unable to convert a wav-file into an alaw-file : [root at asterisk testing]# asterisk -rx "file convert testExtended2.wav testExtended2.alaw" Unable to open input file: testExtended2.wav [root at asterisk testing]# asterisk -rx "file convert testLong2.wav testLong2.alaw" Unable to open input file: testLong2.wav The wav-file is MONO,

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

Will I be able to do the above? > Please help me, I am new to speex. If i am wrong please correct me. No, sampleenc/sampledec work on raw (headerless) files. Either you'll need to work on raw files, or else just use speexenc/speexdec. The latter are more complex, but they produce portable files. Cheers, Jean-Marc

I have been tyring to use the preprocessor standalone by feeding it pcm data from a headerless pcm file (mono, 22050hz) and then write the result to another file. Unfortunately, all I get back is noise (first frame is set to 0, rest is noise). Frame size is set to 440. I just modified testdenoise.c slightly to read/write from a file (see below) but I can't get useful results. What am...

...requency, hardware gain, etc, that aren't relevant to audio. Yes, I could write a script to preserve them, but it sure would be convenient if FLAC were to simply preserve them. (Yes, this wouldn't work on pipes, but that's OK.) I would also find it very handy if when FLAC compresses a headerless raw PCM file, it could (optionally) take sample rate, format, endianness, etc, from the extended file attributes instead of requiring them to be specified on the command line. It should also put them in extended file attributes when decompressing (at least to raw format). And while we're at it...

...If you're running ALSA, I believe there's a switch for arecord that will cause the left channel to go to 1 file and the right to go to another. If you got it to write these to FIFOs then maybe ices could use its wav input? hmmm, the header would be a problem. Don't think ices will do headerless PCM from a file. hmmm. OK, the short answer is, not easily.

That is: *A meta-headerless Ogg le encapsulates the Vorbis I packets .* *The Ogg stream may be chained, i.e., contain multiple, contigous logical streams* *(links).* * The Ogg stream must be unmultiplexed (only one stream, a Vorbis audio stream,* *per link)* This is not to say that it is not currently possible to multiplex...

I've completed the new device for libao that just writes raw, headerless, unformatted audio data to the file of your choice. The driver also supports writing to stdout by specifying the output file to be "-". This is the better way to stream uncompressed audio for now, thereby avoiding the headaches contained in wav files. To add the driver: 1) Copy ao_raw...
