A Brief Introduction to MMF File

Q: "Is there any way to convert a lot of ringtones in .mmf format all at once to MP3 or WAV for example? I know there are a lot of online converters, but they either can convert only 1 file at once or won't recognize this file type. Any suggestions?"

A: Well, MMF is an audio format container that stores Yamaha SMAF data for ringtones using on some old hand-held portable devices, such as mobile phones and PDAs. In a nutshell, MMF is an old audio format commonly used for ringtones, and is incompatible with most modern media players and audio editors on all platforms. That's the reason why many people rummage around the Internet for an MMF player and an MMF file converter. Here, this post will give you a satisfactory answer.
