Is it possible to process audio based on LUFS scale? #469

Open donnyv opened 2 years ago

I would like to take an audio file, process the audio to a certain LUFS scale and then save it to another format with that new volume. Is that possible with CSCore?

I don't know what you mean by certain LUFS scale because LUFS stands for (Loudness Units referenced to Full Scale) but if you want do process a audio file with LUFS specified in EBU R 128 than you only need to apply two filters.

Pre-filter (high pass) cutOffFrequency = 37.5 Hz Q = 0.5

RLB (high shelf) crossOverFrequency = 1500 Hz gain = 4.0 dB

This is possible with CSCore.
