Play Sound File : Deutsch's
This is a stereo sound file
If you are listening through stereo loudspeakers, make sure you have good stereo separation. Listen first with the left and right channels in balance. Then shift the balance all the way to the left. Then shift it all the way to the right. Then bring the channels back into balance again. Notice that when each channel is played separately, you hear a pattern that leaps around in pitch. Equalizing the balance causes your brain to reorganize the tones, so that you hear two smooth melodies instead.
This audio example is presented here in .WAV format.Play Deutsch's (0.0 MBytes) When listening to this sound file, it is best to use equipment with a flat frequency response, so as to avoid spectral distortion. Features that alter the signal in any way, such as spatialization features, should be turned off. Compression algorithms should be avoided, in particular for the stereo illusions. And make sure that the playback amplitude is not too high.
