similar to: masking data graphs

There's a new module in CVS called 'masktest'. I spent the last few weeks writing this program. It can measure masking based on input from people. We need it to obtain better masking curves than we have right now (from Ehmer...). It's not finished yet, but you can get a feeling of what it's supposed to do. It will measure the masking between tone and tone, noise /tone,

(It is a first pass at the issue, so it may not be the final diff that'll end up getting committed. It'd be good to know if it actually fixes the issue for you - sadly, I don't have a big endian system to play with.) Thanks, Jeff.

Hi there ! I checked Vorbis' performace for mono files at approx. 64-80 kbps (it does a good job) and I'm wondering why the current OggEnc still uses Point-Stereo (>10kHz) for -q4 and -q5 I know, we're usually unable to percieve those phase correlations above 10 kHz, But a Dolby Prologic Decoder isn't. I think a future version of OggEnc which is able to use a user-selectable

Hi! Can someone say to me, how the following values are assigned? I assume that it concerns different frequencies, but which?

Well, in the world of audio compression it's never boring... :-) Full press release from Dolby: http://www.aac-audio.com/press/aac.pr.0104.AACencoder.html My comments: Looks like Dolby will start licensing AAC encoder that targets consumers and the products they use like CD rippers, jukebox players, etc. Also, it looks like that this encoder will be Low Complexity AAC ("The AAC Consumer

Dear R developers: The following R program produces a pdf file that does not survive ghostscript distillation correctly. The undistilled version is at http://welch.econ.brown.edu/temp/try.PDF while the distilled version is at http://welch.econ.brown.edu/temp/try.pdf . When previewed, the points are wrong in the distilled .pdf version, but only in one of the two points invokations (huh?) . The

Marvin, fair enough. Via's licensing terms appear to apply to encoders and decoders only, and not to transports, such as Icecast ("An AAC patent license is needed by manufacturers or developers of end-user encoder and/or decoder products"), so using Icecast to transport an AAC-encoded stream is not a violation of the AAC is not mentioned in the Icecast documentation (that I can

There are registry entries that are needed to add some other drivers. Extracting them into a function will help adding SUSE VMDP support. --- v2v/windows_virtio.ml | 311 ++++++++++++++++++++++++++++---------------------- 1 file changed, 176 insertions(+), 135 deletions(-) diff --git a/v2v/windows_virtio.ml b/v2v/windows_virtio.ml index 14ffc51..8a0b529 100644 --- a/v2v/windows_virtio.ml +++

You only have to read the header once for a stream, and libogg2 provides a convient bitpacker which can

Hi folks, I've been dickering around again, wasting the time away.... and today Brian Zisk (chief Vorbis Evangelist among other things) said, "Hey! We need to demo to the world on the 4th of April!" Hooo boy. Time to suck it up and bang it out. The Vorbis libs are not a problem. I'm in process of checking in my new psychoacoustics (they're real pretty!) based on

Hello All, I'm having problems accessing getting a directory listing from samba(3.0.23d) with win xp clients. I can mount a share from win xp, create a directory, create a file, edit the file, etc. But listing the directory contents is fickle. If its a very small directory things appear to work fine. But a directory with around 30 files seems to hang and eventually returns "File Not

I must say this is a very confusing issue. I generate AAC+ on an open source system which downloaded some code during installation from the 3GPP source. It appears the encoding software is being freely distributed, and hardware which decodes the stream pays a licence fee at point of manufacture. We have such hardware. In a number of locations. One brand has AAC+ only, not AAC. I note VLC

Im having trouble with a sports site im creating for a client of mine. The part is where the Team Captians for each team in the league go into the admin section to submit a match report for each match. The form looks like this: TEAM 1 BATTING: (these are all drop down menus that pull the player names from the database) There are 10 of these rows that look like this, 1 row for each player.

I would very much like a lowpass option because for FM radio broadcasting I don't want to encode frequencies above 15khz. I'm waiting for this option before switching to ogg from mp3(lame).
