In signal processing, an audio converter or digital audio converter is a type of electronic hardware technology which converts an analog audio signal to a digital audio format, either on the input, or the output. They are common in numerous technologies —notably in computer sound cards, digital cellular phones, portable recording devices, and digital audio workstations (DAW).

  • In signal processing, an audio converter or digital audio converter is a type of electronic hardware technology which converts an analog audio signal to a digital audio format, either on the input, or the output. They are common in numerous technologies —notably in computer sound cards, digital cellular phones, portable recording devices, and digital audio workstations (DAW). Once converted to digital format, digital audio signals and file formats can be processed in any of a number of ways as allowed by software —including converting to audio CD or MP3 formats. Different types of converter units can operate at different resolutions which largely determines the resulting sound "quality. " Depending on their quality and cost, converters also differ in their handling of: electronic (radio) interference signal-to-noise ratio (SNR) electronic noise shielding and rejection digital noise floor handling, oversampling, (input and/or output) simultaneous playback and recording clock jitter "Resolution" generally refers to both bit and sample rates (though it may occasionally refer specifically to the sampling rate; being the more variable of the two. ) For example, an inexpensive brand consumer sound card for computer has a typical operating range of around CD quality — 44,100 samples per second,, with 65,536 allowable values for volume (16 bits, giving <math>2^{16}</math> values).
