Semiparametric double-index Klein Vella 2009 estimator question.
Dear List's Members, I'm trying to implement "1. Roger Klein and Francis Vella, ?A semiparametric model for binary response and continuous outcomes under index heteroscedasticity,? Journal of Applied Econometrics 24, no. 5 (2009): 735-762. " estimator. I have a technical doubt about the choice of the optimizer for the likelihood function maximization. That of pg. 743, th...

Change 48 khz sample rate limit
...with the following command: $ oggenc --resample 192000 input.wav Of course, if your original material is already at 192 khz, there should be no need for resampling. BTW, a 192 khz signal may be audio, but certainly not human audio. Is that one of those songs for cats or dogs? -- Lucas Clemente Vella lvella at gmail.com

Opus hiding lower volume instrument
...e this is some kind of bug, because the piano is discernible from both Vorbis and MP3 encodes at similar bitrates (around 140 kb/s, which should be transparent for my not-so-good hearing in any encoding). What is best way for me to send the files so you can check for yourselves? -- Lucas Clemente Vella lvella at gmail.com -------------- next part -------------- An HTML attachment was scrubbed...

Multichannel Vorbis encode
...emap table that maps the channel order from SMPTE order to Vorbis order. What is this SMPTE order? Vorbis specification was updated to include channel order for 6.1 and 7.1 audio, but I can't update the patch to include them because I don't know what is this SMPTE order. -- Lucas Clemente Vella lvella at gmail.com

recommended opus bitrate / opusenc setting for general?
Hey. I just wondered,... which is the recommended bitrate and further settings of opusenc (like complexity and framesize) for general music (e.g. including classical music) to achieve more or less transparency? Talking about CD level audio (16bit; 44,1 kHz; Stereo) The only source I could find regarding that was: http://wiki.hydrogenaud.io/index.php?title=Opus#Music_encoding_quality But that

[PATCH 0/1] opusenc support for WavPack input

Change 48 khz sample rate limit
Hi!, I wondering if It's possible to change 48khz sample rate limit?, I'm Planing to encode with OGG codec a audio signal but I need that OGG Encoder works with 192khz of sample rate. It's Possible? Any Suggestions?

heckit with a probit
Hi I have data for voting behaviour on two (related) binary votes. I want to examine the second vote, running separate regressions for groups who voted different ways on the first vote. As the votes are not independent, I guess that there is an issue with selection bias. So, I think I would like to fit a heckit style model but with a binary dependent variable - so, in effect, two successive

How to get the actual bitrate?
Dear all: I'm a developer in china, and i really want to know how to calculate a ogg audio file's bitrate and then i can get the duration by file size. thanks very much for your answer. Best wishes. Aaron Jie. -------------- next part -------------- An HTML attachment was scrubbed...

opus vs vorbis
did another test of many. NeroAAC q=1 @400kbps and Vorbis q=10 @412kbps shared 2nd place. OPUS @330 kbps - 3rd place. LAME MP3 q=0 @320 kbps - 1st place. ---JPEG file attached--- Please disable speech synthezation in OPUS for 96 kbps and up. I don't want my music sound like from a phone speaker! Or what is the problem? Modern codec at high bitrates should produce nearly bit-exact sound, not
