can i convert a wav file to a digital signal without using DAQ?

[Mr_ask]

i tried the coversion of a sine wave to digital signal, ofcourse it doesnt work on converting wav file to a digital signal. i am also new in labview. i tried to explore it but there are many functions that i can't use.

so my these are my questions.

1) is a .wav file is an analog signal?

2) can i convert it without using any DAQ device?

tnx guys! i'll post the programs that uses quantization of a simple sine wave. i tried it to .wav file but it didnt work.

.WAV is a digital "signal". It uses Pulse Code Modulation to encode analog signal. You don't need a DAQ device to "convert" it to analog. Any computer with a sound card, and media player can "convert" a .wav file to the analog audio signal it represents
