Maybe this is a dumb question, but I can get it
In an iMac (no line input) my audio input is an USB CODEC coming from a vinyl turntable.
It gives me very low level sound and there is no volume control for that input.
So I want to apply en effect (amplify, compressor, etc) to increase volume BEFORE the sound is recorded.
When recording, I can have gain in the output, but not in the recorded sound track itself.
Or, can I record the modified output in another bus or track?
(I need +15 db)
Regards.
