Normalizing the audio

Report · Nov 22, 2017

I'm putting together my film's audio including the camera audio and lav mics and have read and watched a lot of tutorials of which many recommend for example normalizing the audio for all peaks to -3 db and then some say for tv the audio peak should be -12 db and some say - 24 db so go figure ?

2. Anyway, my common sense would tell me not to normalize the audio to for example - 3 db or some other fixed number because that would mean that a normal quiet dialogue speech would be peaking at the same loudness to the listener than somebody shouting which would not make sense, correct ? So if that's the case would the solution be to have to go over each audio clip manually and make sure for example normal talk dialogue would peak out consistently for example in the -10 db range and loud scenes to max out peak out in the - 3db range ?

3. I recorded the actors' audio with xlr mic lavs stereo not mono to a tascam audio recorder but for some reason on the Adobe Audition timeline it comes out only from one speaker which i can fix quite easily by the effect Fill left from right, or actually perhaps even better just right clicking and then clicking Audio Channels and putting a checkmark on both Left and Right checkbox vertically on top of each other. I guess that's acceptable as well ?

i ran three passes with the noise capture and that worked best for me. If the same background ac type of sound is prevalent in most of the audio clips, i assume i could save the noise capture setting as a favorite and run it on multiple audio clips by using batch process i assume? instead of trying to apply the effect to every clip individually

remember to calibrate your speaker/headphones first

you can use either Sonarworks/SPL for calibration or diy with for eq, play a pink noise and apply graphic eq to just one channel. make all sliders zero except one one at time and write down the number where the sound matches the same apparent volume as the other speaker. finally play all to set master gain against other pink channel because eq'ing changes volume. for volume, SPL meter playback c weight 75 SPL pink noise or set comfortable talking level with pink noise -23db in os.

I used the Essential Sound's auto-match feature for music which puts it at -25 Lufs automatically on both Default and on Balanced background music preset options, which sounds a bit louder than the similar beginning music I hear on any of the recent box box office movies I watched on Amazon for comparison. How come ? Secondly, I assume its not an issue to the distributor or the buyer as long as the audio levels are consistent throughout, correct ?

lufs is a highly variable measurement weighted by loudness, duration, and overall time. lookup how to get the same lufs value in mixing, gain, and compression. also, change your true peak in the algorithm's setup.
