I'm writing a script that quite specifically transcodes a large number of files. I query the files from JR, and then intend to normalize and transcode them to a specific format using ffmpeg (MCWS is not providing all the options for transcoding I need via mcws, but I don't think that's a task for JRiver anyway). Ideally I would like to employ R128 normalization, and avoid the double pass (Volume Analysis) too. JRiver has that data, so I thought I just use that.

As it turns out, ffmpeg requires 4 parameters:
Integrated Loudness (IL), which I assume is Volume Level (R128) in MC
Loudness Range (LRA), which I assume is Dynamic Range (R128) in MC
True Peak (TP), which I assume is Peak Level (R128) in MC
aaaaaand
Measured threshold, which I have no idea what it might be.

Does anyone know if my assumptions are correct, and if I can get measured threshold from MC audio analysis data?
