AAC vs. MP3 tests @128 - Test #1 Options

[JohnV]

Hey Ivan, just started doing your AAC vs. MP3 @128 Test #1. For those who dont know, below is the test announcement. But, anyway, it seems that 16 samples to evaluate (12 different) is a bit too much even for me to evaluate "correctly"..
Are you really going to include this many samples in test #2 also and 30sec samples?
How many results you have got so far?
Just did the first part of the test, second one to go...

Hi All

Ok, WavRate is almost finished, only thing that needs to be done is multiple test analysis (but project file is already compatible with that).

What's new:

- Better look&feel  Small glitches corrected, like playback info
- Automatic randomization of the items prior to testing
- Slider selection of the range of playback
- Automatic encryption of the output files (security purposes)

You can download wavrate from:

http://www.psytel-research.co.yu/downloads/wavrate.exe

Ok, so first test iteration will be castanets test:

Codec info for the Test #1 could be found here:

http://www.psytel-research.co.yu/downlods/...s_codecinfo.zip

This zip file is enrypted - I will supply everyone with the password when listening test #1 is finished.


Please unpack those LPAC files into the same directory and open those .wrf files from the wavrate.  You can rank each codec with mark ranging from 1 (bad) to 5 (excellent) in 0.1 increments.

Please perform those tests carefully, and comment your results for each item as much as you can - tell me what do you think what's wrong with particular test item and why you think it deserves particular mark.

Please send saved results (File/Save...) to:  listening_tests@psytel-research.co.yu  - subject "Castanets Test"

Next test will incorporate larger sample (30 seconds)
