Yon lòt se echantiyon, ki se rediksyon an nan yon siyal kontinyèl nan yon siyal disrè. Yon gwo aplikasyon se konvèsyon onn son. Echantiyon Audio itilize siyal dijital ak batman-kòd batman pou repwodiksyon nan son. Li nesesè pran odyo ant 20 - XNX Hz pou moun tande. Pousantaj echantiyon ki pi wo pase sa yo ki ozalantou KNUMX kHz - XNXX kHz pa ka bay nenpòt ki plis enfòmasyon nan zòrèy moun nan. Sèvi ak filtè diferan ak DSP lojisyèl ak ADC a &amp; DAC a, echantiyon nan odyo ka repwodwi nan teknik sa a.

Another is sampling, which is the reduction of a continuous signal to a discrete signal. One major application is the conversion of a sound wave. Audio sampling uses digital signals and pulse-code modulation for the reproduction of sound. It is necessary to capture audio between 20 - 20,000 Hz for humans to hear. Sample rates higher than that of around 50 kHz - 60 kHz cannot provide any more information to the human ear. Using different filters with DSP software and ADC's &amp; DAC's, samples of audio can be reproduced through this technique.
