After reading http://mp3.radified.com/mp3.htm I sent Rad an explanation of some things as I understand them. He liked it and posted it on his site (still unlinked, use the URL below). Can somebody with better understanding of psycho-acoustic terms and the vorbis model check it and comment on it? In particular I didn't know how vorbis handles quantization noise. If you reply with

I would like is someone could give me a few hints on how to distinguish whether a WAV file is uncompressed or it was created by decompressing mp3 file - I usually could take a look at the file through Sound Forge and look if there is a freq. cut-off (usually above 16kHz) or if there isn't one - then I can easily tell by listening if there are high-frequency artifacts (common for mp3). Is there

Hi I want to create a vector of colors that are as different from one another as possible. ?rainbow states "Conceptually, all of these functions actually use (parts of) a line cut out of the 3-dimensional color space...". This suggests to me that the resulting colors are all placed on this "line" and are equi-distant along it. The resulting color palette is a range of

So I have been going on over the documentation trying to figure out the exact layout of Pitch Linear Textures and find some missing values. First Question: What's the correct layout of pitch linear textures in memory? Is padding of the pitch added at start or at the end? Do they have some kind of header? Currently I see them as a normal texture matrix with just pitch at the end of each row

Hello, When used in SILK mode, is there a way to manually modify the pitch (F0) of the speech signal before resynthesizing during Opus decoding? In the below, we have modified the pitch lags of (4), e.g., with a constant scaling factor 0.5 to decrease the pitch of the voice by one octave. However, the result was perceptually the same as without modifying the pitch lags. +---------+

Everyone, With the update to Centos 7.5 it is apparent that we lost the Courier 10 Pitch fonts that were in "xorg-x11-fonts-Type1". Does anyone know how to get this back. Greg Ennis

This patch fixes two issues in nv40_miptree_layout. First, pt->width0 is used, which is the size of the whole texture, while width, which is the size of the mipmap level, should be used. Second, the current code does not 64-byte align the pitch of swizzled textures. However, on my NV40 this causes a pgraph error regarding the pitch register (and sometimes a system lockup too), which is fixed

Hi there, I was browsing the speex code when I stumbled across something I could not understand the reason, and thought maybe it was a bug? In LTP.C function pitch_search_3tap, after searching for the best pitch candidate, the function returns the last pitch candidate rather than the best pitch candidate, is this normal? kind regards, Sufian

Hi guys, Here's two patches I'm planning to apply to simplify the pitch quantisation. Can you test them and let me know how it works?

We all know that currently Vorbis is the only codec out there that doesn't add any silence to the decoded file, so when you decode your .ogg file the resulting .wav will be exactly the same length as the original one. This is very useful when encoding gapless songs (like live concerts...). But since Vorbis is a lossy codec, even though there is no silence added, sometimes you can still hear a

Hi, I've googled it and look in voip-info.org <http://voip-info.org> without any success. Hope someone can point me to the right direction. I saw a couple similar questions, but don't see any answers. Fedora Core 2 2 X100P(clone) PSTN Asterisk 1.07 Everything seems to be running fine, but on occasion, Asterisk answers the call with high pitch screech sound (like fax or modem

Hi! Why is Ogg Vorbis better than mp3? Which basic technologies has Ogg Vorbis, that f.ex. lame doesn't have? Ogg Vorbis has a different psycho model than mp3, but what is the names of these models and what is the differences? Which advantages have Ogg Vorbis, that cant be implemented in mp3/lame due to compability reasons? <p>Thanks in advance! <p><p>--- >8 ---- List

I won't bother quoting all of Moz's statements of how sound is interpreted by those blessed/cursed with tape recorders in their heads :) I will add that his whole explanation of perfect pitch perception easily offers an explanation as to why some individuals will only archive flac/pac/ape (Moz - do you?) and those of us that do not perceive that level of detail and are fine using ogg

I've just installed RC2 and I'm very excited about the quality. It's so much better than MP3. This is the first version I've used since I just found out about Ogg Vorbis. I did notice that very high frequencies seem to be missing but since not many people can hear much above 18 KHz it's not much of an issue. I suppose this resolves the hiss problem so prevalent in MP3.

I wonder what psycho-acoustic model is used in ogg vorbis. Did they create their own model (this requires big listening tests) ? Or is it something that was already there, like gpsycho ? <p>--- >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 'vorbis-dev-request@xiph.org'

Hi everyone, For those who like to play with experimental stuff, I've got something new to test. If you compile with --enable-vorbis-psy , Speex uses a variant of the Vorbis psycho-acoustic model to shape the coding noise. So far, I've obtained a slight increase in quality, but I'm interested in feedback from others. This still needs a lot of tuning and has received only a minimal
