Why won’t my Android play M4A?

M4A is an audio file format developed by Apple that is commonly used for audio books, podcasts, and music. M4A files provide high-quality audio in a compressed format, allowing for smaller file sizes that take up less storage space while maintaining good sound quality.

Many Android users have M4A audio files they would like to play on their devices, such as audio books downloaded from Audible or music purchased from iTunes. However, Android does not natively support the M4A format. This often prevents Android users from being able to listen to M4A files they already have on their phones or tablets.

In this article, we will look at why M4A files do not play on Android, options for converting the files to a compatible format like MP3, and apps you can install to allow your Android device to play M4A files.

M4A Format Overview

M4A is an audio file format developed by Apple as part of their QuickTime framework. It was first introduced in 2001 as the default audio format for iTunes and the iPod. The name “M4A” stands for MPEG-4 Audio, indicating its use of MPEG-4 codecs for audio compression 1.

M4A files can contain different types of audio content compressed using lossy codecs like AAC or ALAC. They are capable of storing high quality audio comparable to CDs while taking up less file space. This makes the M4A format suitable for storing music libraries and podcast episodes.

Unlike MP3 files, M4A files can also include metadata like song title, artist, album, artwork, and more. This additional data is stored in the file header making M4A files ideal for digital music players. However, M4A does have limited compatibility compared to the more universal MP3 format.

M4A Compatibility Issues on Android

One of the main reasons M4A files may not play on Android devices is compatibility issues. The M4A audio format uses Advanced Audio Coding (AAC), while the native Android media player only supports MP3 natively by default, not AAC (source).

AAC was designed to be the successor to the MP3 format and is capable of achieving better sound quality at smaller file sizes. However, MP3 gained wider adoption earlier on and is still the most common format. As a result, Android’s native media apps don’t support AAC or M4A files out of the box.

This incompatibility with the default media apps is why you’ll need to download a third-party app to play M4A files on your Android device. While it’s a solvable issue, the lack of default support for such a common format like AAC/M4A in Android remains a headache for many users trying to play their audio files.

Installing Apps to Play M4A Files

There are several apps available for Android that support playing M4A files that you can easily download:

One popular app with M4A support is VLC media player (https://www.videolan.org/vlc/download-android.html). VLC is a free and open source cross-platform multimedia player that can handle most audio and video formats.

Another good option is Poweramp (https://play.google.com/store/apps/details?id=com.maxmpz.audioplayer), a feature-rich music player for Android that includes M4A playback support. The full version requires a small one-time fee.

For a free option, check out Rocket Player (https://play.google.com/store/apps/details?id=com.jrtstudio.AnotherMusicPlayer), which provides M4A playback and enhanced audio quality options.

Converting M4A to MP3

One of the easiest ways to get M4A files playing on your Android device is to convert them to the more compatible MP3 format. There are many apps and online services that can quickly and easily convert your M4A files to MP3:

CloudConvert [1] is a popular free online audio converter that supports batch converting M4A to MP3. You just need to upload your M4A files, select MP3 as the output, and download the converted files.

If you want to convert files directly on your Android device, Apps like MediaConverter [2] or M4A to MP3 Converter [3] allow quick M4A to MP3 conversion locally on your phone or tablet.

For desktop conversion, free software like Freemake Audio Converter, Switch Audio Converter, or Xilisoft Audio Converter can batch convert M4A playlists or albums to MP3 format on Windows or Mac.

The resulting MP3 files will be playable on any Android device. Just transfer the converted files over and you’ll be able to listen to them seamlessly in your default music player app.

Transferring Converted Files to Android

Once you have converted your M4A files to MP3, you will need to transfer them to your Android device in order to play them. There are a few different methods you can use to move your converted audio files onto your Android phone or tablet:

Using a USB cable – Connect your Android device to your computer using a USB cable. Your device should show up as a drive on your computer. Open the drive, and drag the converted MP3 files into the music folder. USB transfer is fast, simple and works on any Android device.

Using cloud storage – Upload the MP3 files to a cloud storage service like Google Drive, Dropbox or OneDrive. Install the app for the cloud service on your Android device, then download the files. This allows you to transfer files wirelessly.

Using a file manager app – Install a file manager app like ES File Explorer on both your computer and Android device. Use the app to wirelessly transfer files between devices on the same WiFi network. This doesn’t require any cables.

Using Bluetooth – Turn on Bluetooth on both devices and pair them. Then use Bluetooth file transfer to send the MP3 files from your computer to your Android device wirelessly.

So in summary, USB, cloud storage services, file manager apps, and Bluetooth can all be used to transfer audio files like MP3s to your Android phone or tablet. Choose the method that is most convenient for you.

Playing M4A Files on iPhone/iOS

M4A files are natively supported on iOS devices like iPhone and iPad. This is because the M4A format was originally developed by Apple as part of their QuickTime software. M4A files contain AAC audio which is also natively supported across Apple devices and software.

Most M4A files should play without issue directly in the iOS Music app. You can sync M4A files to your iOS device using iTunes. Additionally, M4A files purchased from the iTunes Music Store will play directly on iOS.

However, there are some caveats. Some less common M4A files use ALAC encoding rather than standard AAC. These may not play properly on iOS devices unless converted to AAC first. Additionally, some downloaded or user created M4A files may be encoded in non-standard ways that cause compatibility issues.

Overall, the M4A format has excellent support and compatibility on iOS, especially when using files created properly through Apple software and services. But occasionally M4A files from other sources run into playback issues that may require conversion before they will work on your iPhone or iPad.


Considerations for Online Audio

Streaming M4A audio files can present some challenges on Android devices. M4A is not natively supported, so streaming apps may have difficulty decoding the format (1). This can lead to issues like choppy playback, out-of-sync audio, or failure to play the files entirely.

Some users report success using apps like VLC media player or KMPlayer to stream M4A files, as they contain their own decoding libraries (2). However, results seem to vary across devices and Android versions. Downloading the files rather than streaming may provide better reliability.

If streaming is important, consider converting your M4A files to MP3 format instead. MP3 has wider compatibility across apps and platforms (3). There are many free online converters available to re-encode M4A to MP3 while preserving reasonable audio quality.

If you’re trying to play M4A files on an Android device and running into issues, there are a few potential solutions covered here.

First, you can try installing a third-party media player app from the Play Store that supports M4A playback, such as VLC Media Player or JetAudio. These apps may have the codecs needed to properly play M4A files.

Alternatively, you can convert your M4A files to the more widely compatible MP3 format using a free online converter or desktop software. Once converted, the MP3 versions should play fine when transferred to your Android device.

For iPhone/iOS users, the native Music app supports M4A playback so no additional apps or conversion is needed. You can simply sync the M4A files directly to your iOS device.

Lastly, consider uploading your files to a streaming service if you need access across devices. This avoids format compatibility issues, but requires an internet connection.

In summary, while the M4A format may have limited playback on Android, there are ways to get around this either through media apps, conversion, or online streaming.
