How to Convert WAV to M4A Quickly and Easily

by Christine Smith • 2024-01-11 10:27:33 • Proven solutions

The need for converting WAV to M4A arises when you have too many files to be stored and limited space. WAV, being a lossless format, occupies a lot of disk space, and converting them to M4A makes them smaller in size. Additionally, when you majorly play your audio files on Apple devices, M4A is the apt format. More in detail about the formats and easy ways to convert WAV to M4A are discussed below.

Part 1. M4A VS. WAV: What is a .m4a file

Both M4A and WAV are popularly used formats with major compatibility with Apple and Windows devices, respectively.

M4A format: The format is majorly found when you download a song from an iTunes store on your Apple devices. M4A is a MPEG-4 audio file that is encoded using the AAC or ALAC codec. Being a lossy format, M4A is compressed in nature, which results in smaller file sizes. The format is apt when you are looking for light-weight audio files to be played on your Apple and other devices.

WAV format: Developed by IBM and Microsoft, WAV is a lossless audio format that is uncompressed in nature and known for offering and retaining excellent sound quality. All the file information like the number of tracks, bit depth, mono, sample rate, and others are stored by the format. WAV files are large in size and thus occupy a lot of space on your disk.

When you are finding it difficult to manage storage space of your WAV files, converting it to a smaller sized file like M4A makes sense. M4A is capable of retaining decent quality while considerably reducing the file size and thus works as a great alternative when you have several files to be stored or shared.
