You forgot to add that the relative humidity goes up, a distinct 4kHz peak is audible, and that if there is a full moon, the treble sound-stage is compromised, and if the power generation station which feeds the recording studio is nuclear, the mid bass slows down, (except for the first Wednesday of every month of course!) and that if anyone in the recording studio is wearing a digital watch, there will be a high-frequency pulsating noise which only golden-ears can hear, and if the mixing desk sits on a carpeted floor, the bass will sound woolly, and if there is blue wallpaper in the studio, vocals will sound more forward, and if the singer is weather leather shoes, there will be less sibilance, and if the recording studio is more than 200 metres above sea level, the midrange will sound lifeless, and if any of the microphone jacks are chrome plated, there will be a high frequency ringing, and if there is an airport near the recording studio, there will be more jitter, and if there is a polypropylene capacitor anywhere in the circuit, even digital circuit, the dynamic range will be reduced by 0.7dB.... Did I miss anything?
