similar to: Vorbis for low bitrate speech (10-20kbps)

I am writing a long-run sound recording application using OggVorbis. The user can adjust sound quality parameter to make balance between storage space and sound quality. The input sound is 22050Hz, mono. To maximize the recording capability on a given storage volume, we want the result bitrate as low as possible. I use -q0 parameter and it produces a 32.0kbps stream. It is too high (our

I've decided to support this tag in WinVorbis. I've also added an option to allow or disallow alpha

This will be the last announcement of WinVorbis releases on this list. Visit the website to keep up to date. WinVorbis is now UTF-8 compliant! For some reason VorbisComment doesn't support UTF-8 characters in tag names, only in tag data. Added a case conversion routine which uppercases the first letter of every word and lowercases the rest. It is implemented in the templates by using

I'm rebroadcasting a realplayer stream and there are two problems. The icecast2 sounds tinny and its delayed something like 3secs. Any advice to perhaps use speex as it's talk radio? Can I cut the delay? Here is my ices2 config: http://static.natalian.org/2006-06-21/ices-alsa.xml Here is details of the feed, so you can take a listen:

WinVC has been renamed to WinVorbis as it is no longer just a comment editor. WinOgg is apparently taken! It now supports encoding from WAV files via OggEnc.exe. Unfortunately there is no progress indication per file. See the Options form for encoding options. I have added my own super-fast routine for reading comments & file info. It is limited to single stream ogg files only. See the

I'm trying to encode audio tracks as ogg vorbis at very low bandwidths for peer to peer broadcasting. I.e. need to have two streams uploading from modem users, which means the bitrate needs to be around 18-22 kbps. It's not easy to get good quality at this bitrate. The recipe I'm using at the moment is: oggenc Mon-Sep-20-04-0\:3\:27.wav -b 20 -M 22 --resample 17000 --downmix -o

What is DRM? Why do we remove DRM from WMA WMV ? Have you download music and video from Windows Media Player, iTunes, Rhapsody, Napster, bearshare, Spiral Frog, BBC iPlayer downloads? These popular WMA music and WMV movie download programs among the music fans always come with a disgusting word - 'DRM'. DRM (Digital Rights Management) - The anti consumer copy protection that prevents

Shawn sent me a copy of the non-Direct Sound version of this output plugin, and I'm hosting it on my web site's rare software page: http://members.lycos.co.uk/bhafool1/rarities/ I've found it adds far more smoothness and clarity to various low sample-rate audio files, including an 80-minute speech I mentioned previously, due to my soundcard's approach to D-to-A conversion

dear vorbis developers, it would be very useful, if oggenc would support constant low-bandwith bitrates for testing. something from 20kbps to 44kbps, so anyone could test streaming over modem and isdn. audio quality doesn't matter. mörk --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list, send a message to

Hello All, Just a short note to add my vote for a HUGE round of applause to the CentOS team for their untiring efforts in getting releases out the door. I've just upgraded several servers to 5.6 and it all "just works". None of the team's work is easy to accomplish, especially when less-than-useful complaints keep popping up from thoughtless users who don't appreciate

hi folks, in my (unlucky) first test of ogg vs other encoders, i found a case where wma and mp3pro sound much better than ogg at 64k. can anyone suggest a setting that i haven't tried yet that can rival the wma and mp3pro samples at 64k? it's the "gravel effect" that is troublesome. the part in question is the first 15 seconds of this wave file:

Hi All, I have two questions. I have an icecast2 server installed, and I need to set up a Linux-based computer that sends a church's programs to the icecast server. (Both worship and teaching.) What application do you suggest? It would be really pleasing if I wouldn't need X11 to use the software, and it would display (with charactergraphics) the current signal level. The signal

I am trying to use the speex echo canceler and preprocessor with sipXtapi to develop a sip user agent. the sipXmedialib call flow graph uses 10ms frames and I am not sure what the implications are if I try to change this. The documentation seemed to indicate that a 20ms frame was recomended, but it didn't go into the consquences of using other frame sizes. We are going to use headsets

Is stereo vs. mono, and 22khz vs. 11khz even a fair comparison? 22khz vs. 11khz: 22khz, by definition, gives the 22khz stream much more frequency range and *opportunity* to sound clearer.

Just to let everyone know I'm now broadcasting an IceCast2 Ogg Vorbis stream of my LPFM station courtesy of MediaCast1 (http://www.mediacast1.com) for 10 hours a day Monday to Friday 20:00 - 08:00 GMT.
