I have to follow this directives on a Sony XDCAM 4222 50Mbit 25fps PAL timeline with 8 x 24bit 48kHz audio channels .
Alignment Level (AL) shall be –18dBFS with respect to maximum audio coding level (PPM4 on a BBC PPM – IEC type IIa). The Permitted Maximum Level (PML - as defined in ITU-R BS.645-2) must comply ITU-R BR.1384.1 and ITU-R BS.1726. Peaks should not exceed a level -10dB below the digital full-scale level (0 dBFS) when monitored by a “quasi-peak programme meter” as specified in IEC 60268-10.
Loudness control on all audio formats The method to measure the loudness of an audio program is settled by the recommendations, ITU-1770, ITU 1771 and ITU-Document 6/175-E.
Program Loudness Level represents the ordinary level of the program resulting from the measurement of the entire contents analyzed whole (from start to the end, and all audio channels making up the soundtrack). The Program Loudness must conform to R128-EBU
“Short-term” LKFS values shall not be higher than –21 LKFS for the whole program. “Long-term” Loudness must be –24 LKFS ± 0,5. In both cases the gate must be active at a threshold at -8 relative to the target “Long Term” value (- 24 – 8 = -32 LKFS). Short-term and long-term LKFS shall be measured for each audio program accompanying the picture (ie: Dubbed stereo, original language stereo, M&E stereo tracks, etc.).
It is possible create and Adjustment Layer with Premiere CS6 or CC and easily make sure to fix the audio of all 8 channels to respect the limits?
Wich effect I have to use ? With wich settings ? It must be done for each audio tracks or I can use an Adjustment Layer or an Effect directly to the Master output ?
