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 HE-AAC
Apple HE-AAC
Ogg Vorbis **2011** (AoTuV 6.02b)
CELT **2011**
**[Public listening test](http://listening-tests.hydrogenaudio.org/igorc/Public%20Multiformat%20Listening%20Test%20@%2064kbps.htm)**
Even the single result is helpful

The test is extended until 10th of April. We still need more results for samples 11 and 14-30 (14,15....29,30) and results for other samples are welcome as well.
