What is the main reason to convert OGG files to MMF?

Converting OGG to MMF is useful for creating very small, compatible ringtones and alerts for legacy mobile devices that require SMAF/MMF playback.

Will converting audio from OGG to MMF affect its quality?

Yes, the MMF format is optimized for low-fidelity, short audio clips, so expect a noticeable reduction in audio quality compared to the original OGG.

Can MMF files be played on modern smartphones?

Generally, MMF files require SMAF-compatible decoders and are mostly supported on older feature phones; modern smartphones often do not support MMF playback natively.

What Is This Tool?

This tool converts audio files from the OGG format to the MMF format. OGG is a versatile, open container supporting various audio codecs, while MMF is a specialized format for creating small, device-compatible ringtones and alerts for legacy mobile phones using Yamaha's SMAF technology.

How to Use This Tool?

Upload your OGG audio file containing Vorbis, Opus, or FLAC streams.
Choose MMF as the output audio format for conversion.
Start the conversion process to generate a compact ringtone or alert file.
Download the resulting MMF file for use on compatible legacy devices.

Key Features

Converts from open OGG audio files to MMF format used in mobile ringtones.
Supports repackaging audio for low-memory, low-CPU mobile devices.
Optimizes audio into small sized files compatible with SMAF players.
Preserves compatibility with legacy feature phones requiring MMF playback.
Enables migration and archiving of legacy mobile ringtone collections.

Examples

Convert a Vorbis-encoded OGG clip into an MMF ringtone for a feature phone.
Transcode a spoken alert in Opus-encoded OGG into an MMF file with embedded samples.
Archive legacy handset ringtones by converting modern OGG audio to MMF format.

Common Use Cases

Creating very small ringtones and notification tones for older mobile phones.
Preparing compact audio for low-memory devices with SMAF/MMF support.
Migrating music or voice recordings stored in OGG into legacy-compatible MMF files.
Archiving and compatibility testing of legacy mobile ringtone collections.

Tips & Best Practices

Use short audio clips as MMF files are best suited for brief, low-fidelity sounds.
Expect reduced audio quality due to format optimization for low bitrate and synthesized playback.
Verify device compatibility to ensure that the target device supports SMAF/MMF decoding.
Keep original OGG files to maintain high-quality backups before conversion.

Limitations

Audio fidelity is limited; MMF files support only short, low-quality synthesized or low-bitrate sampled sounds.
Conversion may result in quality loss as full-waveform audio is mapped to limited instruments and samples.
MMF format requires compatible SMAF decoders; modern devices may not natively support playback.
Only suitable for small ringtones and alerts, not for full-length music or high-resolution audio.
