Before going into the details of the procedure on how to record phone internal audioI think it may be of interest to you to know what I’m talking about and why this could be useful for you.
Well, when we talk about the phone’s internal audio, we mean all those sounds that are played directly by the smartphone’s operating system or by the applications it is running. A striking example is the soundtrack of a video game, to which various sound effects introduced by the developers can then be added.
In short, recording the phone’s internal audio can be very useful for making other people hear what the phone is playing. If you are a youtuber (or want to become one), also recording the internal audio of your smartphone could be essential to produce quality content.
How to record android phone internal audio
Android it is the world’s most popular mobile operating system. If you have a smartphone equipped with the latter and you want to learn how to record the internal audio of the phone, read on: you will find explained how to achieve your goal right below.
Some Android smartphone manufacturers, for example Huawei, have implemented in their devices a native feature capable of both recording the screen and the internal audio of the smartphone. For other devices, however, it is necessary to resort to third-party applications.
In any case, unfortunately it is not possible to record only the internal audio of the phone: in case you only want the latter, you will necessarily have to extract it from the video that will be captured.
In case you have a smartphone that has a native functionality to record the screen, usually just pull down the notification curtain and press on the icon Record screen. Let’s take a concrete example: if you have a Huawei device, you need to swipe from top to bottom, near the top edge of the display, in order to open the Android Notification Center. At this point, swipe again from top to bottom on the Notification Center, to display other quick launch icons on the screen.
Once this is done, tap on the icon Record screen. When the countdown is over, the recording will start. Alternatively, you can start recording by holding down the keys Volume Up + Power Off for a few seconds.
To stop recording, just press on instead Stop, which you find above. The recorded video will be placed in the multimedia gallery of the smartphone, under the entry Screen recordings. This feature records the phone’s internal audio on its own, so you don’t have to do anything about it. If some step is not clear to you, you can consult my tutorial on how to record the screen of Huawei smartphones, where you can find other useful information in this regard.
If your smartphone does not have a native functionality to record the screen, I recommend using the app Record Screen Recorder, which is free and is compatible with most animated terminals from Android 4.4 or later. It doesn’t require root to work, unless you’re using Android 4.4.
That said, to download and install Rec, open the Play Store, search “rec screen recorder” and select theapp icon (a white video camera on a red background) from the search results. After that, just tap on the item Install and wait for the system to complete the installation operation.
The application, as mentioned, can be used for free, but to remove the advertising banners and unlock some extra features (such as the ability to use predefined presets for recording) you have to pay 2.79 euros via in-app purchases.
Once you launch the Rec Screen Recorder application, you need to set various preferences related to recording, using the menus Dimension (i.e. resolution), Bit rate and Duration. After that, tick the box Audio and type the file name final video.
At this point, tap on the item Registerthen up Allow (to allow the app all the necessary authorizations) and su Start now: Recording will start after a 10 second countdown.
To stop recording, you need to call up the Android Notification Center (by swiping down from the top of the screen) and select the item Tap to stop recording from the latter. Alternatively, you can go back to the main screen of Rec Screen Recorder and tap on Stop.
All recordings are saved in MP4 in the folder /rec/ of the smartphone. Of course, the movies are also accessible from the app Gallery and from any file manager. If some details are not clear to you, I invite you to consult my guide on how to record the screen on Android.
Once the screen video is recorded, if your intent is to get just the audio track, you will have to proceed with the extraction of the same. To do this, I advise you to use the online service Convert.Filesalso available directly from smartphones using a common browser, for example Chrome.
To take advantage of Convert.Files, you simply have to connect to the official website of the service, press on the item Browse and select the video you want to extract the audio from. After that, select the correct Input format (Input format, e.g. MP4) and the Output format (Output Format, e.g. MP3).
Finally, tap on the item Convert and the portal will convert the video into an audio file, containing only the smartphone’s internal audio. Once the conversion is finished, the portal will download the audio file in question to your smartphone.
In case you just can’t extract audio this way, you might want to consider copy the recorded video file to your computer and to use third-party programs, such as Pazeera Free Audio Extractor (Windows) or Movavi Video Converter (Windows/macOS). For all the details of the case, I advise you to consult my tutorials on how to transfer files from Android to PC and how to extract audio from a video.
How to record internal audio on iPhone
In case you own a iPhones with iOS 11 or a later version of the Apple operating system, you can record the screen of your “iPhone” using a native function integrated into the smartphone.
To use it, you just have to call the Control Center by swiping down from the top right corner of the screen (if you have iPhone X or later) or from bottom to top (if you have a iPhone 8 or earlier) and tap the button with the symbol REC. Once this is done, the recording will start after a short countdown.
In case you don’t see the record button in the iOS Control Center, you can add it by going to the iPhone home screen, tapping the icon Settingsthen up Control Center and then up Customize controls. At this point, just tap on the icon + that you find in correspondence with the item Screen recording And that’s it.
To stop recording your screen, just press on red dot located in the upper left (iPhone X and later) or on red bar present above (iPhone 8 and earlier) and tap on the item Stop. I remind you that screen recording is also stopped when the iPhone screen freezes.
You can find the iPhone screen recordings in the app Photo of iOS, more precisely in the section Video. Recordings are saved by default in MP4 format and already have the smartphone’s internal audio.
in case you only want to get the phone’s internal audio from the video you just recorded, I invite you to follow the instructions I provided at the end of the chapter on how to record the phone’s internal audio on Android (the procedure is the same).
If, on the other hand, you want to transfer the video to a computer to work it better, I invite you to take a look at my tutorial on how to transfer videos from iPhone to PC.
