Thanks Steve. I've merged this with GT3b2 and you can d/l a version of oggdropXPd compiled from this merged code at: http://homepage.ntlworld.com/jfe1205/OggVo...9GT3b2QKT32.zip. Please remember that this is experimental code only, at this time. The Vendor String is somewhat lengthy and includes the word 'EXPERIMENTAL'!!
Just to make sure I understand. This version has:Garfs GT3B2 tuningQuantumKnot's HF tuningIt does not have:QuantumKnot's low bitrate pre-echo tuningIs that correct?

More testing, or just more time to see if there are any bad reports from the field?
The oggdropXPdV1.7.9GT3b2QKT32 seems to produce different files from QuantumKnot's oggenchfr.exe. Does the difference of compiler settings cause this behaviour? And is this nothing worth worrying about?gt3b2qk32.pngThank you guys for your work anyway.
I'm not sure what compiler John used. I used VC.NET while he probably used VC6 with the Intel compiler. If that is the case, then it is not unusual for the files produced to be different. Or you could try ABXing the files.
I just encoded my entire collection for testing with the experimental build of OggDropXPd, and interestingly enough, it became smaller by about 3 percent. I saved about 300 megabytes on a 10 GB collection encoded with gt3b2. Interesting that your tunings would have a positive gain of lower average bitrates as well as hypothetically better sound.
Awesome. Less typing for moi. But just a minor point. Time to update the about box too
It comes as no surprise that all the codecs are easily ABXable, but it is surprising that both the SBR based codecs (AAC HE and PRO) perform badly. The encodes sound the worst from the lot. The AAC LC encode sounds better than HE for the tabla part, but when electronic music starts it looses out heavily.
Hi,I was testing QK HF tuning of Vorbis, and may I say that it is without a doubt absolutely super work Well done Quantum Knot !!!Okay, so I tested low bitrate performance with a music track that has a classical Indian instrument called the 'Tabla' in the beginning. I also tested other codecs at 64 kbps CBR and ~64 kbps VBR. The codecs were AAC HE and LC (Nero), and mp3PRO (Nero). For the vorbis encodes I used oggdropXPd encoder at q = 0.The bitrates of various encoded files are as follows:Ogg Vorbis==========V 1.0.1 67QKTune beta 3.2 63AAC==========AAC HE (VBR) 61AAC HE (CBR) 64AAC LC (CBR) 64mp3PRO==========VBR 51CBR 64It comes as no surprise that all the codecs are easily ABXable, but it is surprising that both the SBR based codecs (AAC HE and PRO) perform badly. The encodes sound the worst from the lot. The AAC LC encode sounds better than HE for the tabla part, but when electronic music starts it looses out heavily.On the other hand Vorbis 1.0.1 suffers from high freq noise but does reproduce the tabla better than SBR based codecs. QK Tune 3.2 does so much better than 1.0.1 and produces smaller files as well.The ranking based on my testing:Vorbis QK3.2 > Vorbis1.0.1 > AAC LC > AAC HE > mp3PROI want to upload this sample file. How do I go about that? I would appreciate it if some of you could do a little testing on this file and confirm the same.
hmmm....It beat HE-AAC? That is most unusual since Vorbis is very mediocre at such low bitrate while SBR is absolute magic!! Definitely need some verification here. You can upload the sound file in the uploads section, in the thread called 'Vorbis samples'.
What type of music should we be listening to to find problems here? Aphex Twin type stuff, some of which has the highest average bitrates, or for instance, The White Stripes album De Stijl, which has some of the lowest average bitrates in my collection, where losing bits might affect the sound more? In other words, should we be looking at the extremes here, or is there no particular pattern to look for?
Hello,I´ve merged Vorbis CVS and qkt32.tar.gz for a private linux-compile. I found a piece of "normal" music sounding strange. (However, vorbis 1.0.1 doesn´t seem better to me on this sample but I may have to check this again...)http://www.hydrogenaudio.org/forums/index....ndpost&p=188853Maik
