Document Summary

Audio can be converted or digitized through either audio sampling or audio synthesis: you can us the sine wave/function to represent or describe sound. Time: (something you cannot control) something that just flows and generates the sound. Phase/ time shift: has to do with where the sound starts (we usually don"t care about this because we cannot detect it, but it is important when dealing with where we want our sound to appear to be. In order to convert the sound you must take samples of the sound, the amount of samples you take depends on the sampling rate (vertical measurements) Sampling rates that are too fast will be very accurate, but the file will be extremely large. Sampling rates that are too small will be a very small file, but will not be very accurate. Higher bit depth replicates a more accurate sample.
