When music is recorded, the diaphragm of the microphone moves in the same way that a listener’s eardrum would, but that movement is recorded electronically rather than converted into nerve responses. The idea is that, later, the information on that recording can be stored and copied, then ‘played back’, amplified, and ultimately to set the air in your listening room into the same motion that existed at the recording venue. If all goes well, your eardrums will move in about the same way as a listener’s at that original performance. In fact, this, in a nutshell, is the whole objective of high end audio. It is the job of every link in the audio chain, from the mike, to the recording device, to the storage medium, to your player, to your preamp, and amplifier, and of course to your speakers, to preserve and reproduce the original musical signal. But...and you knew this was coming....most speakers on the market today make no attempt, no attempt what-so-ever to preserve the precious timing information in the signal that you, and those who recorded it, have spent so much time, effort and expense to deliver to those rear terminals. They are ‘time in-coherent’. |
