Some phones and ringtone tools store melodies as RTX ringtone text, while music players and editing software commonly expect MP3. Converting the melody lets you play or share it as an audio recording.

What the RTX format is

In the Audio category, RTX usually contains a ringtone encoded in RTTTL (Ring Tone Text Transfer Language), not recorded sound. It is a text sequence describing notes, durations, octave and tempo, commonly associated with older Nokia ringtones and ringtone-making tools. An RTX file therefore has to be rendered into sound before it can become an MP3.

What the MP3 format is

MP3 is a compressed audio format supported by phones, computers, media players and many editing applications. It is useful for sharing and playback, but it stores rendered sound rather than the editable note instructions in an RTX ringtone.

How to convert RTX to MP3

Online on 101convert.com

  1. Upload the RTX file on the converter page. Multiple files can be added for batch conversion; each file must be within the size limit shown on the page.
  2. Select MP3 as the output format and set the bitrate before converting.
  3. Start the conversion, then download the resulting MP3 file or files.

Offline with desktop software

RTX is ringtone notation, so audio encoders such as FFmpeg cannot convert it directly. First use an offline RTTTL-to-MIDI converter to open the RTX file and save it as MIDI. Then open the MIDI in MuseScore (Windows, macOS or Linux), select a playback instrument, and use File → Export to render audio. If your MuseScore version does not offer MP3 export, export WAV and encode it with FFmpeg: ffmpeg -i ringtone.wav -codec:a libmp3lame -b:a 192k ringtone.mp3.

Quality and compatibility

The RTX file does not contain a recording or a specified instrument sound; the MIDI renderer supplies the instrument, so the MP3 may sound different from the ringtone on its original phone. MP3 export is lossy, and increasing bitrate cannot restore audio detail that was never present in the RTX notation.
