RTTL meaning in Academic & Science ?

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 jintu 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

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.
