I have listened to the audio. It sound very good. There are missing bass cartainly because of the 100Hz high pass filter mentionned in poita's link.

I make a quick sync with the GOUT. Here it is :

I compared the waveform between the GOUT track (up) and the 16mm track (down). Here it is between 6:32 and 7:20

The 16mm looks more compressed but less limited. Strange.

Thank you very much poita, I hope I will have the entire scan soon.
