Hi, I'd like to compare recording quality of
portable recorders.
I only care about the line-in input of these portable recorders.
I'm thinking:
* play audio through a good DAC and feed the line-in of each recorder
* copy audio files off the SD cards from the recorders
Sorry, I guess I don't understand ...
* level match the inputs. Probably based on "sox
FILE -n stats"
output change input levels on each recorder to match levels.
* play audio again through the DAC and feed the line-ins
... why you want to do this?
Forget what I've written. You seemingly want to test a copy of a copy,
while doing some processing. IMO that won't give a valid result.
