Document Summary

Sound is used to: easily capture attention of users, facilitate easy learning or marketing, set the mood, communicate over the web via internet. Purchasing: purchase a cd (watch for copyright infringements when using sound on your webpage, download sound from companies or itunes. Digital-to-analog (dac) converter for playing audio: quality of sound depends on: Sample rate: number of times per second that the waveform is measured. Measured in hz (1000 hz = 1khz) Must have 2 or more samples per wave (nyquist limit) More samples per wave means better sound and bigger audio file. Sample rates: 8 khz: telephone voice quality, 11. 025 khz: am quality, 22 khz: fm quality, 44. 1 khz: cd. Sample size (bit depth): each measurement taken that is represented by a value. Higher sample size means better sound and bigger audio files. Mono signal: one channel / stream of data reproduced equally on both speakers.
