- Remarks
-
The max TP level for linear audio in production is -1dBTP (see EBU R 128 and EBU Tech 3343).
Where bitrate compression is used, -3 dBTP may apply (see EBU Tech 3344).
Note that (Q)PPM and true peak are different measurements.
With the introduction of loudness measurement (see 0010B), PPM measurements are being replaced with Loudness and TP measurements.
The (Q)PPM test item is 0085B.
