A digital signal is created up of 2 levels only-0 and 1. This signal is transmitted in the form of bits with each bit either nil or 1.To convert an analog signal to a digital format analog-to-digital converters are used ;to convert a digital signal to analog form digital-to-analog converters are used. The digital music is silent, distortion free to a large extent and reconstructing it to its original analog form is a straightforward process. Digital music has become popular because of its advantages in recording, distribution and production.

The analogue music is first converted to a digital form and then sampled at a particular bit resolution. The higher the sampling rate and bit resolution the more accurate is the digital music got. This music is then the subject of digital signal processing methods where various filtrations occur. In this step different effects can be added to the music signal. After the completion of this step, music is held in various devices such as CD, DVD, USB Flash Drive, Hard Disk ; etc .Also info compressing methodologies are applied to reduce the size of the music files. Some of the usually applied systems are Vorbis or MP3.The ultimate step is conversion of this digital media into analog form. The digital music is down sampled at a selected sampling rate and bit resolution to obtain the first music.

assorted sound effects can be applied to the digital sort of music. A typically used custom for this purpose is MIDI ( Musical Instrument Digital Interface ) .A MIDI controller is a device which is utilized for the control over various musical instruments, programming effect modules and automating mixers. It could also capture live musical performances into electronic form and then transfer it to a synthesizer .Synthesizers are devices which create electric signals by mixing signals of different frequencies. There are various kinds of MIDI controllers-keyboard controllers, guitar controllers, wind controllers, percussion controllers and foot pedals. Stage lighting has gained momentum over the last few decades. Dazzling light effects may also be made by the employment of little MIDI controllers.
