Problems to Record Internal and External Audio on Android Phones: How to Fix it

The possibility of recording sound with our mobile phone can be very useful on many occasions. However, it is possible that our need is different, since we may want to record the internal or external audio of our terminal. In both cases, both the methods and the problems that may arise in the attempt are totally different.

Problems to Record Internal and External Audio

It is not the same to want to record the audio that is emitted by our smartphone natively, whether it comes from an app or from the sounds of the system, than to capture the external audio that that surrounds us. The first method is one of the most desired by those who make games online and want to have a quality record of everything that sounds on the mobile. In this case, it is a clean audio that does not affect those other sounds that occur in our environment.

The problem

The main problem with which users find themselves, is that Google eliminated the API for developers that allowed to create developments to capture the internal audio of our mobile. It is a measure that possibly serves as a retaining wall against pira-cy, but that limits many of the actions, and more in an operating system that was born with the open source DNA of the Linux Kernel . Therefore, it is not that your mobile does not work correctly, it is that you will not find at hand the option to capture this internal audio.

There’s a solution?

The most efficient alternative is to become an Android root user and download an application such as SCR Pro. However, these alternatives are usually paid and require that a less advanced user or who does not want to root their mobile phone can capture the internal audio . However, there is an alternative that does not require rooting and that can serve a large majority

First of all we will have to get a 3.5 mm jack to jack audio cable . The requirement in this case, in addition to the cable, will be that our mobile phone has this audio input (disappeared in almost all the high-end of 2020) and that our PC has an input line. Then we have to download a program to capture the internal audio, such as Audacity. Once connected mobile and PC via cable, we can capture the internal audio of our mobile without external interruptions.

Problems with external audio

In this case, all mobiles have their own tool to capture external audio. The same sound recorder will be able to capture everything that sounds around us. If we have problems recording external audio, there are several solutions that we can carry out to try to solve it.

Check the microphone

If, despite recording, we do not hear anything, it is possible that the microphone of our mobile phone is dirty or plugged. What we will have to do is clean the connectors, although it may also be convenient to remove the cover or casing that we have on, since it often makes it difficult to record the external audio correctly.

Deactivate Bluetooth

It is another cause of external audio not being recorded correctly. This is because if the pairing with any external device is active , the recording will not take place from the mobile’s microphone. In that case we must disable Bluetooth and try again.

Restart the mobile

The simplest solution and the scope is often the right one. A restart of our mobile could solve the problem . It is possible that the recording app that the microphone depends on has been corrupted or is causing a conflict with another application. When rebooting we can leave doubts and check if everything works again correctly.
