audio capture into android from sound amp

Hi All,

i need to capture audio from an external amp into android.

I made a cable which connects mono out to mic, got a normal 4 pole to 4pole cable, chopped halfway then joined speaker from Source to mic on recorder side (Android phone)
its working fine but i have couple of issues and needed help to find a better stable solution

1: audio has noise, any way to cut it? (to be honest i can live with it, its not extremely critical, point 2 is more)
2: i have noticed weird behaviour, if i plug android side first then it uses the cable to record audio but if source side is plugged in first then android cable then it doesnt detect and uses builtin mic only.

is there any way or official cable i can use, this is quite annoying as this setup is not mostly used by tech people so they can plug cable in wrong sequence and app not to work.
thanks in advance.

It may not be the fault of your smartphone. However, some lower-end Android phones (even today) tend to have a lot noise and unfavorable measurements. I would recommend looking up the smartphone you have for audio quality. GSMArena is a great source. If not them, some other site should have some detailed measurements.

For unidirectional (only facing 1 direction) use a lavalier mic.
And omnidirectional is all directions...
Binaural recording is going to be expensive...

Audio Technica makes excellent microphones. If you’re just looking for basic clip on mics, those can be had for very little money.

Hi Mastering,

thanks for response. Im using samsung phone, noise i am playing around by adding transistors  so thats easy one to sort out.

on other side im not using MIC. i have output from another device, be it AMP or another device.
if i plug cable in to android first then amp , it works fine.
if amp is already plugged in then i plug cable into phone then it wont use external device.
seems like android is detecting somehow. but when i plug headset it detects it. i wanted to know what makes android detect an external device. is it some sort of msg?
