Summary
M4A (MPEG 4 Audio) is primarily used for audio files, particularly those in music. It uses lossy compression, which reduces file size but can also reduce audio quality. M4A files are often used when the quality of the audio is important and the file size needs to be minimized, such as in music streaming.
MP4 (MPEG 4 Part 14), on the other hand, is designed to hold audio, video, and subtitles in a single file. It is commonly used for video streaming and other multimedia applications. MP4 files can use either lossy or lossless compression, allowing for a balance between file size and quality. MP4 is fully supported on all devices, making it a reliable choice for multimedia files.
In essence, use M4A when dealing with audio-only files where you need to balance quality and file size. Use MP4 when you need to include audio, video, and possibly even subtitles in a single file, especially for multimedia content that will be streamed online.
