What is the 3G2 file format?

3G2 is a mobile multimedia container optimized for low-bitrate video and audio recording on mobile networks and devices, commonly used for short mobile videos.

Why convert 3G2 audio to MMF format?

Converting 3G2 audio to MMF lets you create small, device-compatible ringtone files suitable for legacy phones with SMAF-compatible audio playback.

Can I use MMF files on modern smartphones?

MMF is a proprietary, legacy audio format primarily for older feature phones and requires specific decoders, so it is generally not supported on modern devices.

Tips & Best Practices

Use short audio clips optimized for low-fidelity MMF playback to maintain quality
Verify your legacy device supports SMAF/MMF playback before converting
Choose simple melodies or alert sounds as MMF format has limited audio fidelity and duration
Test the converted MMF file on compatible decoders or device emulators to ensure playback

Limitations

Audio quality is constrained due to 3G2's lossy codecs and MMF's low-fidelity design
Advanced audio features in 3G2 may not convert properly due to MMF's limited sequenced and sampled audio support
Converted MMF files require specific SMAF/MMF-compatible decoders and are not widely supported on modern platforms
