A close-up of a time-coded vinyl record
Vinyl emulation allows a user to physically manipulate the playback of digital audio files on a computer using the turntables as an interface, thus preserving the hands-on control and feel of DJing with
vinyl. This has the added advantage of using turntables to play back audio recordings not available in
phonograph
A phonograph, in its later forms also called a gramophone (as a trademark since 1887, as a generic name in the UK since 1910) or since the 1940s called a record player, or more recently a turntable, is a device for the mechanical and analogu ...
form. This method allows
DJs to
scratch,
beatmatch, and perform other
turntablism that would be impossible with a conventional keyboard-and-mouse computer interface or less tactile control devices.
A ''digital vinyl system'' (DVS) may include a special time-coded vinyl record or be purely software.
Characteristics
Vinyl
emulation normally uses special
vinyl records which are played on conventional
turntables. The vinyl is a recording of analog audio signals often referred to as
timecode. The turntables' audio output - the timecode recording - is routed into an
analog-to-digital converter, or ADC. This ADC may be a
multi-channel soundcard or a dedicated external
USB or
FireWire
IEEE 1394 is an interface standard for a serial bus for high-speed communications and isochronous real-time data transfer. It was developed in the late 1980s and early 1990s by Apple in cooperation with a number of companies, primarily Sony an ...
audio interface box,
DJ controller device or compatible mixer (usually distributed with the software). The ADC sends digital time code information to the software, which then translates the signal into corresponding changes in the playback speed, direction and position of a digital audio file. The audio file will react as if were pressed directly onto the record. The manipulated audio output of the program is then sent back through the
DAC or the computer's sound card, and can be routed into an audio mixer where it can be mixed like any other analog audio signal.
The result is digital audio playback that sounds like music manipulated by an analog vinyl recording. However, there is always a short delay between the needle's reading of the time code and the software's playback of the audio. The delay time is treated as a
figure of merit for vinyl emulation products. A shorter delay allows the DJ to have better response and control of the music and is usually not noticeable by the user or listener.

Software packages
Final Scratch was the first vinyl emulation software sold publicly. Since its release in 2001, many similar software and hardware packages have been developed and marketed.

Some vinyl emulation software products are marketed with specific
time coded vinyl, while others are software-only products.
