Digital recordings are often done at a depth of 16 bits, which breaks up the dynamic range between the loudest and quietest portions of a signal into 65,536 steps. We use the finer resolution of 24 bits, which divides the signals’ loudest-to-softest dynamic range into 16,777,216 steps, allowing for far more accurate rendering of the quieter parts of the audio.

changes as faithfully as possible. The higher the sampling rate, the better. Our consoles use a sampling rate of 46,000 times per second. To capture any given frequency, a digital signal’s sampling rate must be roughly twice that frequency. The sampling rate of 46 kHz is more than adequate for capturing all signals in the audible range—the human ear can not hear the sounds whose frequency is higher than 20 kHz. |
