The following queries extract mean/standard deviation (RMS error)'s of the difference (in semitones) between measurements on the Original (audio-cd) recordings and identical measurements on Compressed/Decrompressed versions of these recordings for two microphones (see below). The differences are compared (the Microphone button) with the effect of a change in recording conditions, i.e., the difference between the measurements on recordings using a fixed HF condenser microphone (Sennheiser MKH 105) and those on the parallel recording using a head-mounted dynamic microphone (Shure SM10A).
