gusto ko lng po malaman ung mga settings na dapat i tweak sa pc ko para makapag record na ko using usb connection. i mean the levels, dB and the settings...
I can't give you settings on levels because I don't know enough about your recording chain.
What YOU should do is this...
Set things up so that you are monitoring your input signal. It does mean that you are hearing what you are physically recording. It will require that a) the GT10 has an audio 'return' from the computer so that you can hear the levels going into audacity, or... failing that, you can hear a realtime output from another soundcard.
I'm not familiar with the GT10 but I expect some routing difficulties trying to do a realtime monitor from the computer/software output. To do that, you will have to set audacity so that the GT10 is the input and output audio device. If you can monitor your playing while recording, without hearing ANY latency, then you can properly record. This is VASTLY different from hearing the GT10's direct output since you would want to determine if the signal is distorting before going into the computer, which is something you would want to avoid.
Supposing you have a proper monitoring setup, the rule of thumb is to get the loudest possible signal into your computer without distorting the input converters or ADC, as we like to call it. Try to do a run through of your recording and listen to the loudest portions. Distorting the input almost sounds like bad transistor distortion. If you do hear distortion, before the next take, reduce your input levels by a few dB, taking note of the loudest part of the song. Play that part while adjusting levels until the distortion goes away. Once that is done, record to your heart's content.
