Greetings!!!
There has been significant advancement since the last 64kbps test. The Nero HE-AAC and Aoyumi Vorbis encoders improved, Apple added HE-AAC capability, and we have a new low delay codec with high quality: CELT.
The following codecs are presented in this test:
Nero 1.5.4 HE-AAC
Apple QuickTime 7.6.9 HE-AAC
Ogg Vorbis AoTuV 6.02 Beta
CELT 0.11.2
Public Multiformat Listening Test @ ~64 kbps [March 2011]
Well, have fun! :rolleyes:
If you don't want download separate packages there is all-in-one package http://listening-tests.hydrogenaudio...nd_samples.zip
Note: Important workaround was made. It is not uncommon to see that some soundcards have isues with not 48 kHz sample rates. Aslo until moment CELT is optimized for 48 kHz while other codecs are well tested at 44.1 kHz. To avoid these limitations all decoded files (Vorbis and Nero, Apple HE-AAC) were resampled with very highly transparent resampler SOX VHQ while CELT files were directly encoded from the resampled source. The resampling hadn't impact on final results.
Even the single result is helpful.
