Digital Audio Glossary

ADC - This stands for Analogue to Digital Converter/Conversion. This is a device and a process that converts recorded analogue data into digital data which enables it to be used and altered on a computer using a music software such as Logic, Reason ect. Converting analogue to digital data makes the recorded data clearer.
Alias Frequency - These frequencies are always apparent when one converts analogue to digital. They are also known as sidebands. However, through manipulating the sample rate in accordance to the frequency of the audio one wants to record, these sideband frequencies will not be heard.
Binary - This is the number system that computers use to read digital data. It is also known as base 2.
Bit Depth - This determines the dynamic range of recordings. Ultimately describes the number of 'bits' recorded for each sample. The higher the bit depth, the more frequencies one will be able to hear in the recording (high and low frequencies).
Clipping - This occurs when an amplifier/speaker tries to output a voltage too high. This causes distortion of the data being transmitted.
DAC - This stands for Digital to Analogue Converter/Conversion. This is the reverse process of ADC and can be done through the use of the same device.
dBFS - This is the measurement of Digital data. 0dBFS, is the maximum volume.
Dither - This is an intentionally recorded noise (atmospheric,white noise) which enables recorded sounds of a lower frequency to be heard.
Digital audio interface - This translates binary information into audio so that one can hear it. Most computers have this built in and the better it is - the better the sound quality as its sample rate is higher and captures more information.
Digital effects processor - These were designed to be used by DJ's to change the sound of the songs they were playing. However, recently Effects processors are now used in studios on pre-recorded sounds. Effects that a Digital effects processor may have vary, depending on the manufacturer. However, the most common are reverb, delay, flange, filtering and limiting.
Digital mixing console - An electronic device for changing the dynamics of recorded sounds. These are most commonly used in recording studios.
Sample rate - This is used to convert analogue into digital data using the base 2 number system. The sample rate takes samples of data in order re produce the audio waves in another form (digital/analogue).It is measured in Hz/KHz.
