Frequently Asked Questions
This depends on what is more important to you: quality or file size. WAVs require more storage space, but the audio quality is great. M4As are smaller while maintaining acceptable quality. Also, when making your selection, take into account the type and model of your device, because M4A and WAV are not very widely supported.
The main disadvantage of the WAV format is the file size. WAVs take up a lot of space, so if you have limited storage, maybe it will be better to convert audio files to a format that’s smaller in size. Also, some devices do not support WAV.
