Hi Who can give me list of companies or VoIP product strongly based on speex? I want to know whether it is good enough for real enviroment like packet losing etc.. Regards bay

Hi, The leakage problem you describe is very, very common and you will need to do something to address it. I modified the version of Speex I use to implement an adjustable max gain. If you look at speex_compute_agc in preprocess.c, you will see: if (agc_gain>200) agc_gain = 200; This max of 200 is usually more than enough to amplify leakage which occurs either in the sound

Hi, I might have written to this mailing list previously about this but I've been experiencing some mailing problems so I write this again. First of all, thanks Jean-Marc Valin for your continued efforts on speex. I must say that I am very impressed with Speex and further more the innovative features recently added in 1.1. They have worked great for me. Question 1) What is the return value

Hello Mailing List, I am a Speex supporter and user that would really like to know how much memory Speex uses to decode a 8kHz, 16kHz and 32kHz (primarily the 8kHz) and is it possible to use a 1kBytes of RAM to decode a 8kHz stream? (I was thinking of the possibility of using a ATmega168 to decode Speex) //P?r, Sweden

Hi, I am working on a VOIP implementation were one of the key design goals is zero user configuration. Similar to Skype. What I've come to notice is that my soundcard (NForce4 based) leaks audio from the playback path to the recording path. This is probably not unique for my hardware at all and will happen on some percentage of all users of my software. (All of this is Win32) What happens is

Hi I'm debugging why echo cancellation does not work in my app using the DUMP_ECHO_CANCEL_DATA flag. What format does the data I receive have, looks like 16bit integers just dumped but when plotting it in MATLAB I do not get a raw audio data signal I expected.

Hi, Rhett, echo_diagnostic.m can produce an echo canceled file along with the possible warning messages. Can it cancel the echo properly? It may announce the "Drift estimate is ..." message if the recorded sound contains not only echo but also other sound like a near-end speech. In other cases, it may truly indicate a mismatch of the sampling frequency. Regards Kaiyu On Thu, Feb 6,

Speex uses very few bits, so every bit you corrupt is likely to be heard. You would need to use "fractions of bits" at a time. Even then, it may be hard to hide data efficiently (so it's

Hi I'm new to speex list but joined because I'm needing to port the Neon to ARM64. On that function, saturate_32bit_to_16bit(), I noticed the ifdef's are wrong. The first version is for normal arm 32 bit arm and should be used for arm32 and thumb2 but not thumb1. The second version is 32 bit neon and should be #ifdef __ARM_NEON__ I've done a third version which is 64 bit neon.

I'll try to explain. I want to create dll with only one function "Encode" that will encode file to speex format. In my application I will use this function from 16 threads, if it will work correct? 2011/12/6 ???. <xialonghua at vip.qq.com> > > ** > two thread send frames to only encoder at same time,two thread will use > one buffer > .it will work wrong if not

anyone know how to get the aarch64 fork pulled into the mainline speexdsp?

But using the ACM codec I just need to put the speex content into the wave file data chunk and then windows will play it?

I've filed a bug for aarch64 https://github.com/xiph/speexdsp/issues/7 and provided the port in a fork with a pull request. We need someone to review/merge in the pull request? It provides the source code, but my testing was under Android builds, so there would be some configure changes needed to build it stand alone.

Hi folks, here's a press release (yes, sorry, sorry) regarding what's going on with Xiph at the current IETF meeting. Every time we're asked 'why haven't you standardized any of your codecs through the IETF?' we explain that we've been trying for coming up on ten years. This release is about the latest step. If we (along with the other companies supporting

Hi, i think it will work correct.when one thread use encode,the others wait for. in java, i think we can do like this: synchronized (Encode) { Encode.encode(short[] in, byte[] out); } In the doc of speex: it says the speex is not thread-safe. ------------------ ???? ------------------ ???: "????? ?????????"<romius99 at mail.ru>; ????: 2011?12?7?(???) ??4:00 ???:

Marco, Thank you for your response. Is there a way I can determine if the synchronization is perfect or not? If not by how much it is off. - Elston -----Original Message----- From: Marco Pierleoni [mailto:pierleoni.m at gmail.com] Sent: Monday, May 10, 2010 3:46 PM To: Elston Sa Subject: Re: [Speex-dev] AEC - Echo is cancelled however.....

Hi everyone, I have been using vorbis for ages as audio codec for archiving movies and I have always been happy with it, but now I have been thinking about two things: I) Multi-channel Up until now I mostly encoded to stereo; now I am thinking of encoding more movies to 4.0 or 5.1. I heard that vorbis does not optimize for channels > 2, i.e. that 6 channels is just stereo*3. AAC is

I'm going to use speex to compress sound that was record from a sound board. What container should I use so it will be able to play in some sound player available for windows, ogg or wave? If I choose to use wav container I simple have to put the speex stream into the data chunk of the wave file? I heard that there is a codec to put speex in a wav file so it can be played in windows media
