similar to: speex user list?

As long as the number of mails doesn't exceed what it is now I see no need for a separate mailing list. <p>>From: giles@xiph.org (Ralph Giles) >Reply-To: speex-dev@xiph.org >To: speex-dev@xiph.org >CC: jm@xiph.org, Darryl Davidson <ddavidson@talisman-intl.com> >Subject: [speex-dev] speex user list? >Date: Sun, 24 Aug 2003 12:59:01 -0400 > >Hi all, >

Hi Ralph, What speexenc does (Speex itself does not know about Ogg) is that it gives packet N the granulepos "N*frame_size - lookahead". In the case of narrowband, the first frame would have granulepos "1*160 - 80", so 80. I can't say about your example because Speex cannot encode a frame of one sample, which is a good thing becuse otherwise, the granulepos would be -79.

Jean-Marc, What exactly does the speex code do to calculate the granulepos? With vorbis it's the 'count of decodable samples including this packet'. So if you had a packet that allowed you to decode 1024 samples since the beginning of playback, the granulepos is 1024, not for example 1023 which would be the *index* of the last sample assuming C-style array indicies starting at

This was also our experience porting the Tremor vorbis decoder to a TI dsp. The vendor toolchain is useless; someone really needs to pay cygnus to port gcc. -r ---

Jean-Marc and others, I'm meeting informally with the AVT WG on monday, and formally presenting our latest drafts on friday. I've been following the vorbis/theora draft efforts, but haven't paid much attention to the speex work. Can you brief me on what I should talk about, what we'd like feedback on, what's new and different from other drafts as far as the speex work goes?

[Woops, forgot to reply to the list ; just sent the following to Ralph] Thankyou guys. > All Speex files (.spx) are encoded in Ogg, so speexenc is all you need for that. > The standard "flac" utility will encode into Ogg with the --ogg switch. D'oh! Have been RTFM'ing an awful lot lately, but I completely missed that flac has an --ogg switch > You may also wish to

Hi folks, we've tried contacting Jean-Marc Valin but email address bounces. We published yesterday an advisory about libfishsound, you can find it at the following URL: http://www.ocert.org/advisories/ocert-2008-2.html The issues seems to affect Speex (since the code is the same) versions <= 1.1.12. While the 1.2beta branch is not vulnerable we advise that you fix with a security release

Hi, I'm porting speex as a DSP task to run using the DSP gateway project. I have some results, but I still need some improments, because I'm still getting some error messages in the mail box system... If someone wants to help... it would be useful. 2006/1/16, Ralph Giles <giles@xiph.org>: > On Mon, Jan 16, 2006 at 04:43:56PM +0100, Christophe Augier wrote: > > >

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

Hi all, This should please all those who want to know more about Speex or Vorbis. Monty and I have just finished writing this paper: "Improved Noise Weighting in CELP Coding of Speech - Applying the Vorbis Psychoacoustic Model To Speex" which you can get at: http://people.xiph.org/~jm/papers/aes120_speex_vorbis.pdf It's probably the best description of the Speex encoder to data and

Using speexenc applicantion (provided in the Speex site) when I try to encode a wav file less than 12,5KHZ in wideband mode it warns that I should do it in narrowband but the time it takes to encode and the final encoded file size are bigger if I use narrowband. The sound quality after decoding seems to be the same. What is the advantage of using narrowband? Thanks. Miguel Gomes

Hi Please acknowledge this message as I am not sure if your organizations still exist. On trying to integrate your 3 formats into an app I find that the position of the start of each format ID differs. Both "vorbis" and "fLaC" start at char 29 (the 30th char in the file) and "speex " starts at char 28 (the 29th char in the file). Speex appears to correlate with

Hi All, The following patch is for the http://easytag.sourceforge.net/ software to add speex support. Since easytag uses vcedit.c & vcedit.h that are directly copied from http://svn.xiph.org/trunk/vorbis-tools/vorbiscomment/ the diff's that I made to add speex support, i thought that the diff I made would very much apply to the vorbiscomment developers. I was personally thing that
