Ring Tones Text Transfer Language

from Wikipedia, the free encyclopedia

Ring Tone Text Transfer Language (RTTTL) or Nokring is a common format for monophonic ring tones for mobile phones .

Technical details

A ringtone in RTTTL / Nokring format must contain the following three parts in order to be recognized by ringtone programs: the name, the default settings and the notes.

For example, the RTTTL ringtone for "Haunted House" looks like this: HauntedHouse: d = 4, o = 5, b = 108: 2a4, 2e, 2d #, 2b4, 2a4, 2c, 2d, 2a # 4, 2e. , e, 1f4, 1a4, 1d #, 2e., d, 2c., b4, 1a4, 1p, 2a4, 2e, 2d #, 2b4, 2a4, 2c, 2d, 2a # 4, 2e., e, 1f4, 1a4, 1d #, 2e., D, 2c., B4, 1a4

The three parts are separated by a colon.

  • Part 1: Name of the ring tone (here: "HauntedHouse") several characters that represent the name of the ring tone.
  • Part 2: Standard specifications (here: d = 4, o = 5, b = 10), where "d =" is the standard note length. In this case, "4" means that every note without a length specification is a quarter note . "8" would mean an eighth note , etc. Furthermore, "o =" is the standard octave . There are four octaves in the Nokring / RTTTL format. "b =" stands for the playback speed in beats per minute.
  • Part 3: The notes. All notes are separated by commas and include:
  1. Optional the tone length (1, 2, 4, 8 ...). A point after the note length increases the length of the note by half.
  2. The note indication (c, d, e, f, g, a, b (= international tone name)) or pause (p). A diamond after the note increases it by a semitone (cross accidental), there are no b accidental characters in RTTTL .
  3. Optional the octave.
