Does NAM calibration level depend on the playback dBFS level of the training file?
I've searched multiple Youtube videos and forum threads but am still confused.
Basically I have an interface with a max 14.5dBu output level, which I plan to capture some pedals with. No re-amp box, but my understanding (after doing thorough research) is that re-amping is not necessary at all and is simply a viral internet myth (anyway not the point of this post). So my current signal path looks like:
DAW TTSv10 training file -> interface out -> OD pedal -> interface in -> recording in DAW
I'm thinking to lower the training file volume to provide some headroom post-pedal. My question is, if I lower the output level of the training file by say, 4.5dBFS (the audio file peaks at roughly 0dBFS. so after attenuation the peaks are around -4.5dbFS in my DAW) does that make my correct calibration metadata 10dBu instead of 14.5dBu? That makes the most sense to me in my head, but please explain to me if I'm wrong. Thanks.
