Bit Depth

Bit depth, in the context of audio recording and digital audio processing, refers to the number of bits used to represent the amplitude of an audio signal at a particular point in time. It is a critical parameter that determines the resolution and dynamic range of the digital audio representation.

Common bit depths for audio recording include 16-bit, 24-bit, and even 32-bit. 16-bit is the most commonly used in podcast audio recordings.

Here’s a brief explanation of each:

  1. 16-bit: This provides a reasonably good level of audio quality and dynamic range for many applications, including podcast audio.
  2. 24-bit: This is commonly used in professional audio recording and production because it offers a wider dynamic range and allows for a more accurate capture of subtle nuances in the sound.
  3. 32-bit: This high bit depth is often used in specialized audio applications and some digital audio workstations (DAWs), enabling extremely accurate and detailed audio processing.
