It's as close to a delta function as you can get with digital audio. But it isn't very narrow, is it? Your example demonstrates, that this delta function always means something different, depending on actual application. For the one narrow means 1nsec, for someone else 23µsec means narrow. True, it's all application-dependent. A friend does acoustic analysis of various venues. He used to record the impulse response of the rooms on a standard tape deck. He generated the impulse using a starter's pistol. Nowadays, we just play pink noise and do transfer functions. It's debateable whether pink noise at 106 dB SPL is more annoying than repeated gunshots :) -a |
