DAWs today typically use 44.1 kHz or higher sample rates. Early digital gear used much lower sample rates to conserve memory for stored audio. A Speak & Spell from the 1979, for instance, used an 8 kHz sample rate. Sample rate reduction (also called down-sampling) intentionally reduces the sample rate to degrade the quality of the audio.
