Don't think so, ears appear to be able to hear distinct notes/sounds with up
to 10ms interval (above it it becomes a tone). For phase earse are much nore
sensitive (also used for locating sound in stereo field).

But why are you refering to 1ms timing resolution. My (intel pentium) kernel
uses a 100 Hz system timer, and I end up with (for userland apps) about 20ms
timing accuracy.
