Digital audio recording was introduced in 1990s and has now become norm. There are several formats for recording digital audio including Digital Audio Tape (DAT) and hard disk recording. Digital playback devices include MP3 players, CDs and MiniDisks. Digital audio recording and playback offers a clean, noise free and long lasting medium.
Despite technological advances, some audio recording techniques have remained basically same since 1920s. Microphones are still used to capture sound produced by acoustic instruments and voices. Many instruments today, however, are synthesized, and recorded directly onto recording medium without use of microphones.
Computers can be used to automate some of processes in audio recording. Computers can emulate all functions of a recording console and can be programmed to fade in and out and add effects like reverb. Computers open up new possibilities in audio recording which for most part are unutilized in popular music.
