Is there a a way to use TM7 / TM9 for measuring Cinema levels, i.e. Leq(m)? If it is the case, does that give you a start to stop numerical reading?
It is possible in TM9 to select Loudness Type = SPL and weighting filter between linear, CCIR Leq (M), Leq (A), C, or ITU BS 1770 (k). The SPL meter is only real time and does not show a reading from start to stop.
