DEFINED RINGING TONE SEGMENTS IN AN AUDIO SOURCE

A method of using a normal music file, such as an MP3 file, stored in a mobile terminal to produce a ringing tone. The music file comprises a plurality of file segments, some of the segments having associated data identifying the segments such that when the mobile terminal receives a telephone call or message, one or more of the identified segments are used to produce the ringing tone. The associated data can be stored as header information of the music file or stored in a separate memory. The associated data can be provided by a data service from which the music file is purchased. Alternatively, the file segments to be used to produce the ringing tone are selected by the user and the associated data is also provided by the user using a software program.
