Android doesn't allows changing Left-Right balance of device from normal apps like this. Developers cannot do anything into this. Only rooting like methods can work until Android gives developers access to changing balance of audio.
I made this utility app for mainly below reasons -
- While repairing my Mi Piston ear phone I needed to test which wire is left audio channel and which is right and which one is mic. Out of four wires in ear phone this app can help check these wires. It works as Earphone tester or speaker tester.
- To test both ears whether they perceive sounds equally. Sometimes in ear infections or other cases one ear hears much lower than the other. Even in cases of loud sound ears get disturbed. Use it as Ear tester or hearing tester.
- To check headphones, earphones for equal volume on both channels.
People who cannot hear equal from both ears and have noticeable difference are not able to find correct position of audio source. A person with weak right ear will guess position of sound from center as more left!. Take care of your ears.
Whether you are repairing 3.5mm jack, checking a new earphone, headphone or speakers or similar uses this small simple tool can be very useful. Some nature sounds are added because they are giving calm & peace to head :).
