What are three stages that sound passes through when it is computerized?

The three stages are:

1. Digitize or input sound

2. Store the digital data

3. Reproduce or synthesize the sound

While the above is true, you may be looking for a different set of steps: 1. The analog audio passes through some type of pre-amp to amplify the signal enough to digitize. 2. The pre-amp passes the analog audio to an analog to digital (A/D) converter. 3. The A/D passes the now digital audio to an encoder that encodes the audio to the desired format and writes it to disk. Sometimes the encoder just writes the uncompressed stream to disk, or sometimes it is encoded live to a format like mp3. This all depends on the specific application. ---- The above answers are true, but here is my textbook's version of the answer: "Sound passes through three stages when it is computerized: # First, the sound is digitized-- that is, converted from analog to digital. # Second, the digital data is stored in a compressed data file. # Third and last, the sound is reproduced or synthesized (digital to analog or digital out)."
