tried the same with stereo to usb cable …same problem…
As per my understanding from the page u shared, just as a experiment if i connect aux cable from keyboard output to laptop mic input , recording will be distorted. how to change this mic input from mono to stereo (incase if it is find that mic input is mono)…
On many computers the “mic” input only has hardware for mono. If that is the case on your computer then there is no way to make it stereo and you will need to use a different audio device (a different sound card or USB audio interface). For connecting the AUX of a keyboard, you should use an interface that has “line level” or “instrument level” inputs. “Mic level” inputs are too sensitive and will give bad sound.
No. If your mic input is “stereo compatible” (that is, you see stereo choices in its properties in Windows Sound), then the input will realise when a stereo plug is connected and not apply unwanted amplification. But it will still be of lower quality than a proper stereo line-in.
Using “Listen to this device” does not improve the quality of a stereo compatible input, it just sends the signal to your chosen playback device. You can achieve exactly the same result (listening to the input) by choosing Transport > Software Playthrough in Audacity.
If you don’t care about the quality then you can use the input anyway if it is stereo, but you say that it’s distorting. To try to fix the distortion on a stereo compatible input, try turning the input level down in Audacity (see here, by the mic symbol):
If your input is mono mic only and thus not suitable for connection from a keyboard, “Listen to this device” will not make mono into stereo. It will just put the same distorted signal into left and right of your stereo playback device.
