Audio Signal Measurement

Yeah, I know. This article really doesn't fit in anywhere but it's a good article on audio measurement specifications for those of you who are technically inclined. Interesting in how the author points out near the end that "While it’s necessary to use a very good signal source to measure distortion caused by a system component, audio quality is judged by how it sounds, not solely by the fidelity of the DAC output, for example. With this reality in mind, it’s sobering to compare the near-perfection of even low-cost 24-b DVDs and the ±3-dB specification of the best professional speaker systems. Until we improve the transducer that converts electrical signals to sound-level pressure variations, the performance of all audio systems, both analog and digital, will be compromised." Makes you go hmmmmmmmm.......
