But to begin with, let’s approach these phenomena with a sound much simpler than a hand clap — a sinusoidal (or sine) wave. If we depict it as a waveform (like in the above graphic), we’ll see a signal that passes smoothly from peak to trough and back again with beautiful, equal curves on either end.
USB microphones are the most convenient way to record a podcast. Simply connect them to the USB port on your computer and press record — no additional gear required. Yet while USB microphones offer an easy, plug-and-play solution for podcasting, they don’t provide the versatility required to pull off larger productions. For that, you’ll need an XLR microphone.
