Hi everyone, Recently I made an attempt at merging the tunings of GT3b1 into the official Xiph.org 1.0.1 libvorbis code. While 99% of the GT3b1 tunings are independent of 1.0.1, there is one particular value (_psy_noiseguards) which affects the whole quality range. I've chosen to use the 1.0.1 values since they changed since 1.0. Therefore, files encoded in GT3b1 mode (q 5 and above) are slightly larger than normal GT3b1 files. I would appreciate it if some people could test the quality of this encoder and make sure that not only are there no breaks in quality, but that this encoder behaves (quality-wise) the same as both 1.0.1 and GT3b1 in their respective quality ranges. Also, try encoding at lower sampling rates. At q -1 to 4, oggenc will use the Xiph.org 1.0.1 tunings At q 5 to 10, oggenc will use the Sjeng.org GT3b1 tunings, which has better pre-echo and transient handling. (Between 4 and 5, there will be a mix between the two) The thread at hydrogenaudio.org, where I announced this is at http://www.hydrogenaudio.org/show.php/showtopic/17824 Windows and Linux binaries are available at Rarewares (http://rarewares.hydrogenaudio.org), with special thanks to John for verifying, compiling, and uploading. :) Please note that this is experimental and the quality of the files is uncertain. The vendor tag has the word EXPERIMENTAL so that files are tagged appropriately. :) <p>Best regards, Steve. -- -------------------------------------------------- Stephen So, BEng(Hons) PhD Student, Signal Processing Laboratory, School of Microelectronic Engineering, Faculty of Engineering and Information Technology, Griffith University, Nathan Campus, Brisbane, QLD, Australia, 4111.
