| Sound Samples |
|||||
The following sound samples are high quality monaural recordings sampled at 16 bit, 44Khz rates and are in the form of wav files. Monaural samples have been used to minimize the file sizes. This does not degrade the experience as the sources are essentially monaural in nature. The sounds are not calibrated for level but are intended as representative of the character of the sounds.
Many of these samples contain significant low frequency content, ie., below 200 hz. The typical computer sound system is not capable of reproducing these low frequency sounds. It is recommended that one use a high quality headset (one that covers the ears to keep other sound out), such as the Beyerdynamics Model DT 990 Pro, or a high quality home theater type sound system in a very quiet environment.
