Can I convert video content when converting 3GP to MMF?

No, this tool only extracts and converts the audio portion; the video track in 3GP files is discarded.

Will the converted MMF file play on all modern smartphones?

No, MMF is a legacy format requiring SMAF-compatible decoders, which are uncommon on current devices.

Why is the audio quality lower after converting 3GP to MMF?

MMF is optimized for short, low-fidelity synthesized or sampled audio, so audio quality may be reduced compared to the original.

Be aware that video content is removed and audio quality may be lower after conversion.
Use this tool mainly for legacy device compatibility and archival purposes.

Limitations

Only audio from 3GP is converted; video tracks are discarded due to MMF being audio-only.
Converted audio may lose fidelity because MMF targets low-bitrate synthesized and sampled sounds.
MMF format supports short durations only; longer or high-quality audio is not suitable.
Playback requires specialized SMAF/MMF decoders, limiting use on modern platforms.
Certain 3GP codecs may not map cleanly to MMF's audio model, causing compatibility issues.
