Dear members of the auditory list! My name is Marco Kobbenbring, and I am psychology student in Kiel, Germany. I have a problem with my experiment for the diploma, which is in the field of music perception. It includes the presentation of sequentially ordered short sine waves (ascending scale). I generated the sine waves with Winsound v4.23, and stored the sequences as .wav files. The problem is that when I play back the wave files, there appear short klicks with the onset of every tone of the file. They are very inconspicuous, however, under experimental conditions they become audible. I used fade in and out for every tone, so the transition from one tone to the other is smooth. Moreover, I created sound files on two different PCs with the same result, and also conversion of the files to CD player format didn't make a difference. However, the two PCs are possibly not equipped for professional sound experiments. I would be grateful for advice whether there must be something wrong with my equipment. Best wishes!
