What is 16 bit PCM?

The number of possible values that can be represented by an integer bit depth can be calculated by using 2ⁿ, where n is the bit depth. Thus, a 16-bit system has a resolution of 65,536 (2¹⁶) possible values. Integer PCM audio data is typically stored as signed numbers in two's complement format.

Is 16 bit audio signed or unsigned?

16-bit audio is, by convention, usually signed. Think about what PCM audio is: each measure is how far along its axis the speaker should physically rest at that moment in time. Therefore perfect silence is absolutely any repeating value — that represents the speaker not moving.

What is the value of the maximum amplitude of a sample in a 16 bit PCM file?

With common 16 bit samples, the range is from -32768 to 32767 for the largest possible excursion of a vibration that can be recorded without distortion, clipping or overflow.

What is a PCM microphone?

The PCM-100 is designed for premium vocal capturing with its wide frequency response, cardioid polar pattern and switchable low-frequency roll off for eliminating noise. The PCM-100 requires external 48VDC phantom power and features an LED that illuminates when the microphone is powered. More Details.
