&gt; The fact of the matter is that sound (along with everything else we know of in the Universe) travels at a finite speed. In regular conditions, a sound wave propagates at around 340 meters (or 1100 feet) through the air in a single second. This means that even for plain old physical instruments, there exists an audio delay between the moment the instrument is played and the instant the sound reaches the musician&#x27;s ear.<p>You heard it here first folks, in a few years Apple is going to come out with the revolutionary &quot;Cochlea sound&quot;, which has such a small delay your ears are unable to perceive that there is any delay at all (while listening from 10-12 inches from your ears of course)!<p>It will be magical and delight us, and something we never realised we needed until we were told we did. It will become the new standard and a household name, and we&#x27;ll all have to catch ourselves when we say it and try to use some obnoxious generic term instead (LoALPS perhaps: Low Audio Latency Per Sound).
