Ring Tone Text Transfer Language (RTTTL) was developed by Nokia to be used to transfer ringtones to cellphone by Nokia. The RTTTL format is a string divided into three sections: name, default value, and data. The ''name'' section consists of a string describing the name of the ringtone. It can be no longer than 10 characters, and cannot contain a colon ":" character. (However, since the Smart Messaging specification allows names up to 15 characters in length, some applications processing RTTTL also do so.) The ''default value'' section is a set of values separated by commas, where each value contains a key and a value separated by an ''='' character, which describes certain defaults which should be adhered to during the execution of the ringtone. Possible names are * d - duration * o - octave * b - beat, tempo The ''data'' section consists of a set of character strings separated by commas, where each string contains a ''duration'', ''pitch'', ''octave'' and optional ''dotting'' (which increases the duration of the note by one half). The format of RTTTL notation is similar to the Music Macro Language found in BASIC implementations present on many early microcomputers. ==Technical specification== To be recognized by ringtone programs, an RTTTL/Nokring format ringtone must contain three specific elements: name, settings, and notes. For example, here is the RTTTL ringtone for Haunted House: HauntHouse: 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, 1a4The three parts are separated by a colon. * Part 1: name of the ringtone (here: "HauntHouse"), a string of characters represents the name of the ringtone * Part 2: settings (here: d=4,o=5,b=108), where "d=" is the default duration of a note. In this case, the "4" means that each note with no duration specifier (see below) is by default considered a quarter note. "8" would mean an eighth note, and so on. Accordingly, "o=" is the default octave. There are four octaves in the Nokring/RTTTL format. And "b=" is the tempo, in "beats per minute". * Part 3: the notes. Each note is separated by a comma and includes, in sequence: a duration specifier, a standard music note, either a, b, c, d, e, f or g, and an octave specifier. If no duration or octave specifier are present, the default applies. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Ring Tone Transfer Language」の詳細全文を読む スポンサード リンク
