Thread-topic: [CRTech] NexGen Record Capture

Mark Allard is correct - if they are recording the file in realtime - playing out of the AMR, and recording on NexGen's DRR (Digital Reel-to-Reel, if you didn't know!), there will be no normalization applied to the recorded file.  If the audio is cold, then it's cold in the system.  If the audio overmodulates the input of the audio card going into nexgen, then you're going to be clipping all over the place.

Mark's solution is the best way I know of, to solve this problem in real-time recording.  You either need to set the input of the DRR cold enough that it won't clip, or you need audio processing between the output of the AMR and the input to the NexGen DRR.

Instead of recording in realtime, if they transfer the files digitally using the Amb-OS UI, and then use RCS' AFC or AFC Launcher to process incoming audio files, AFC and AFC Launcher will both run the files through a normalization routine before loading it into the NexGen library.

Jim, I’m making an assumption that said file is playing out of the AMR and recorded via the DRR in realtime, yes?

Could it not just be the input gain of the audio card recording into DRR? I would think if that weren't set to 0,  it wouldn't match whatever the file on the AmbOs receiver.

We’re working with a station which uses NexGen to record capture one of our programs off the AMR-100.


However, one of several files consistently sounds over-modulated.  We know the files are all the same level as we have fetched the file(s) off their receiver and they’re all at our standard -6dBFS.


My question is this . . . do you know if NexGen allows you to set gain boost or trim based on each record capture event?  This seems the only logical explanation for the problem.  If we’re right and you’re familiar with the software, could you point us to where the setting lives?


Or, is there something we’re missing??
