Enhanced AAC+, how to compare quality between original file and decode Options

[happysaisai]

Hello,I'm doing with Enhanced aac+ codec, i met a problem ,is there someone knows which tool can be used to calculate the quality between original .wav file and the decoder output .wav file ?
I tried PEAQ, but the ODG value seems very low even though i did not add any error to the stream file.3gp.
Because the decoder output file is delayed, and the length between two files is different, so i shift the decoder output file and made the two files have same length, but still doesn't work, does someone know how to modify PEAQ or the two files?
Thanks.

If you are only comparing one lossy encoding against the original lossless source then you should use ABX instead of ABC/HR, though the later can be used like ABX but you have to conduct multiple trials in order to get any statistical significance.

thanks, but I can't download the ABX from the link ,do you have other way to download ?
