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.

[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

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?

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

Dear Ralph Thank you for your info. My file_read() function only get a specified number (nbBytes) of bytes from the .ogg file and store it in cbits, nothing else lb = file_read(&file, nbBytes, (void *)cbits); Unfortunately I have only 32K (first section) + 8 (second section) = 40 Kbyte of RAM to do all, including the file system management (I get the FS from the EFSL project). Speex

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 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 After much googling, am struggling to find either: a) a command-line utility that allows me to encode to non-vorbis ogg audio (*nix) b) example files of the above Am building a program part of which reads stream meta from uploaded audio files, and so have written a lightweight getid3-like set of classes that do this. Am handling ogg vorbis perfectly well already and would like to test it
