Hello.

There have been some delays, but here are the so awaited results of the latest 64kbps group blind listening test.

http://audio.ciara.us/test/64test/results.html

And the final plot:
Each vertical line segment represents the 95% confidence interval (using ANOVA analysis) for each codec.


Note: Lame MP3 is 128kbps "high anchor" in this test, FhG MP3 is the "low anchor"

Zoomed version without the anchors:


Codec specifications:
  • Ahead/Nero 6.0.0.15 HE AAC VBR profile Streaming :: Medium, high quality
  • Ogg Vorbis post-1.0 CVS -q 0
  • MP3pro (from Adobe Audition 1.0) VBR quality 40, Current Codec, allow M/S and IS, allow narrowing, no CRC
  • Real Audio Gecko (from Real Producer 9.0.1 64kbps
  • Windows Media Audio v9 VBR quality 50
  • QuickTime 6.3 AAC LC 64kbps, Best Quality
  • Lame MP3 encoder 3.90.3 --alt-preset 128 --scale 1. (high anchor)
  • FhG MP3 encoder (from Adobe Audition 1.0) 64kbps CBR, Current codec, allow M/S, no I/S, allow narrowing, no CRC. (low anchor)
Thanks to everyone that participated and helped!

Best regards;

Roberto.

That pisses me off. A lot.

Sure, it was "Hydrogenaudio" that stayed up till 5:30 AM sorting results, it was "Hydrogenaudio" that took shit on every issue that surfaced, it was "Hydrogenaudio" that screened 500+ results ditching the ones ranking the reference...

I'm not an asshole, but I think credit should be given where credit is due. Credits weren't given to ff123's test either, but at least it wasn't misrepresented as being conduced by HA.

sigh...

OK, rant off.

Don't be sad, Roberto. Who needs Slashdot appreciation, anyway? We all love you here at HA.org, we all know you're da man. biggrin.gif
