Hi Randy, thanks for the reply. So, suppose I encode an audio buffer (8000 kHz, MONO, float) of 640 PCM frames. In output I have 4 speex frame of 20 byte

Hello Daniele It would be worthwhile to attach an external serial flash or USB thumb drive, if the intent is store data. This allows for far more flexibility in storage Regards Amit On Fri, Aug 26, 2016 at 11:02 AM, Jean-Marc Valin <jmvalin at jmvalin.ca> wrote: > On 26/08/16 11:40 AM, Daniele Barzotti wrote: > > You're right!

My application have to acquire a 16bit 8KHz PCM stream and

Hi, in a VoIP application, the endpoint A send speex payload to B. B doesn't know how A acquire audio, it only know that the channel is narrowband so, how can B know the size of the output buffer to pass to the speex_decode()? Thanks, Daniele.

Greetings The Unix application 'wavsilence' is a program that takes a WAV file with gaps of silence and creates smaller WAV files, containing the data between the gaps. ( http://danplanet.com/wav/ ) Is there a similar program for ogg vorbis? How difficult would it be to write such a program? --------------------------------------------------------------------------- The usage

Just a few weeks ago, I was thinking of writing a streaming source using libshout and portaudio. I was also considering LADSPA support, to do some minor post-processing before encoding. However, I'm currently developing on Mac OS X, and LADSPA's shared library plugin model has some issues here to be resolved. Another nice feature I have given a thought on is incorporating

>Also, 'portaudio' doesn't appear to produce a static library at all, so it doesn't appear to be possible to get a working splayer executable on Linux unless there is a 'hidden' way to get the portaudio distribution to build one. ("ldd: -lportaudio not found"). I believe splayer is only intended to be a Win32 executable. Note that it is in a directory

The current Asterisk 13 and master git branches have a new feature that will be included in 13.8.0: The ability to compile and run Asterisk with a bundled version of pjproject. ?? Why would you want to do this? Several reasons: - Predictability: When built with the ?bundled pjproject, you're always certain of the version you're running against, no matter where it's

Hello, I try to compile player_example.c from http://downloads.xiph.org/releases/theora/libtheora-1.1.1.zip in Visual Studio 2008 on Windows XP. I built and added to the project libogg-1.3.0, libtheora-1.1.1, libvorbis-1.3.2 (http://www.xiph.org/downloads/) and SDL-1.2.15 (http://www.libsdl.org/release/SDL-devel-1.2.15-VC.zip). When I compile player_example.c Visual Studio shows: fatal error

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, I was wondering if anyone had any advice on an audio library that is better suited to be paired with Celt in terms of latency. I'm working on an application that I would like to have running on both windows/Linux systems.

Dear, I'm sorry if this is not the correct list to post a question about libfishsound but I don't have found a specific one. I'm writing a library that use libfishsound for encode/decode speex and vorbis streams. I would like to incorporate all the functionalities into my static library without any dependencies on extern DLL. Is there a way to compile libfishsound using ogg, oggz,

Hi, First of all, I'm quite new to opus. I'm trying to use fixed point opus on an ATMEL AT32UC3B0512. I added the opus source into mine sw tree, I trim off code I don't use (eg. arm, x86 folders) It compiles, but the generated image is too big to fit in the flash. Have I any way to reduce the source footprint? (Eg. throw away unecessary files, if there are any..) Thanks, Daniele.

It's a question of getting the compiler environment setup to do the port. Much of libshout and ices2 are ready but, certain things like live input are different from whats in windows. karl.

Speaking of portability and people more familiar with SDL: The reason we have two example players for theora is that monty wrote the original example around the OSS audio interface used on several free unix-like operating systems, which immediately excludes win32 and MacOS, even though it used SDL to display the frames. SDL also has audio support, and is quite widely ported. splayer replaces

Hello R-folks, I don't get the color of the legend in a lattice-plot right. I select a palette from RColorBrewer and use (with a col = mypalette argument) it in the barchart plot. The resulting graph shows the new palette in the graph, but uses the standard palette in the legend rectangles. Adding a col argument into auto.key uses the new palette with the legend text, but not in the

I am using 'portaudio' and 'speex' to implement a speech audio capture/playback. Preprocess works fine but not the echo canceller (associated with preprocessor). I have read 'testecho.c' but it didn't help me. What I am doing bad? This is my implementation: One thread to capture and playback, both are different functions called in different times directly from

Hello, Need some help using the speex_echo_cancel. I've read the documentation about the speex_echo_cancellation function: speex_echo_cancellation(echo_state, input_frame, echo_frame, output_frame); (in) echo_state => speex internal state. (in) input_frame => audio captured by mic. (in) echo_frame => the signal that was played in the speaker. (out) output_frame => the
