There’s one final piece of terminology to cover before we move on: sample rates.
When converting an analog signal to digital format, the sample rate is how often the sound wave is sampled to make a digital signal.
Almost always, 44,100Hz is used because that is the same rate for CD audio.
Next up in the Audio Tutorial series I talk about converting audio files and recording audio files on the Mac.
