Greetings!

I am planning to conduce a multi-format 64 kbps listening test under Roberto's supervision. The exact date for the beginning of the test is not set, since I am waiting for Apple to release their HE-AAC encoder sometime in April (according to the rumours).

So far, here is what I was thinking about. Feedback and suggestions are welcome.

Codecs:
  • Nero HE-AAC
  • Apple HE-AAC
  • Ogg Vorbis
  • Windows Media Audio
  • LAME 128 kbps as high anchor
  • Fraunhofer 64 kbps as low anchor
  • mp3PRO maybe
Nero and Apple HE-AAC will be included for sure.
What I don't really know is which Vorbis version to use - either AoTuV3 or 1.1. Same applies to WMA - either Standard due to compatibility or Professional for quality. Last but not least, should mp3PRO be tested again as reference (since there aren't any changes from version used in Roberto's last test)?

As you can see, there will be 6 or 7 (depending on mp3PRO) codecs.

Samples:
  • DaFunk
  • EnolaGay
  • experienca
  • gone
  • Illinois
  • mybloodrusts
  • NewYorkCity
  • riteofspring
  • Scars
I am planning to use 18 samples - 9 from Roberto's old listening test and 9 additional ones. What do you guys suggest?

The results will be calculated in the same way Roberto's results were calculated.

So, what are you thoughts? biggrin.gif

Regards,
Sebastian

Edit: Spelling and typo in the number of samples planned to use.

I'm not sure if abchr-java can force the following options, but I'm sure schnofler can modify his code:

1) the rating scale description should be changed to the "excellent" to "poor" labels; I already know this option exists, but it should be forced from the configuration file

2) the start time should be forced to X sec into the clip without allowing the listener to hear anything before that time, also specified from the configuration file.
