[Mp4-tech] public AAC at 128kbps listening test open

[bond]

Hi!
Since there has been a lot of development in the AAC codec market in the last months, Roberto Amorim kindly set up a listening test, open for everyone to join, aiming at finding out what encoder performs best AAC encoding at an average bitrate of 128kbps.
The used method of comparing codec quality is by performing so-called "Double Blind Listening Tests". In this sort of test, the participant compares various encoded samples against each other and against an uncompressed reference sample. The blind part means that the participant doesn't know which sample was encoded by which encoder. That guarantees there'll be no psychological bias towards his/her favorite codec, or against the codec he/she dislikes.
The AAC at 128kbps listening test is now open. Everyone is invited to participate!
Instructions on how to participate are available at this page:
http://www.rjamorim.com/test/aac128v2/presentation.html
The test will run until February 28th, and may be extended if proven necessary.
Results of already conducted listening tests can be found here:

enjoy
