There appears to be general agreement among reviewers (including those at TAS) that everyone should know how their room influences frequency response. Yet I've never seen a good guide to doing basic measurements in a typical room. Anyone know of any good step-by-step guides based on reasonably inexpensive measurement equipment?
And, while we're at it, we should all be moving beyond the Radio Shack SPL meter, right? It seems that a pretty good measurement rig could be built on the iPhone -- there are several good audio analysis apps out there. Might be a worthwhile article for TAS to pursue -- how to measure frequency response using an iPhone! Faber Acoustical appears to have some helpful information regarding iPhone response curves for its Sound Meter product.
