Companion page for Audibility of Loudspeaker Group-Delay Characteristics

The sound files in this web folder are related to the following 
conference article:

J. Liski, A. Makivirta, and V. Valimaki, "Audibility of Loudspeaker Group-Delay 
Characteristics," in Proc. 144th AES Convention, Milan, Italy, May 2018.

The sound files are examples of the signals used in the listening test described in the 
article. In addition, a sound file containing a pink impulse is included.

The listening-test files contain the specific impulse response both forward and backward 
after each other. The start of the file name specifies the signal as described in the 
article, and the end of the name specifies whether the impulse responses are the original 
ones or the ones convolved with the pink impulse.

For the signals that were not convolved with the pink noise, "1Wa" and "2Wd" were most of 
the time perceived as the same when comparing the original and the time-reversed versions 
of the impulse responses. For the signals "2Wa" and "3Wb" the differences were more 
difficult to judge and the results were almost random. Finally, the signals "2Wg" and 
"3Wa" were most of the time perceived as different when comparing the original and the 
time-reversed versions.
