Audio Bit Depth

Bit depth is the number of bits of information in each sample, and it directly corresponds to the resolution of each sample.

Examples of bit depth include Compact Disc Digital Audio, which uses 16 bits per sample, and DVD-Audio and Blu-ray Disc which can support up to 24 bits per sample.

For us podcast producers in terms of uncompressed audio like .WAV and .AIFF files:

• 24 bit files are MUCH higher resolution than 16 bit files.
• 24 bit captures more dynamic range than 16 bit.
• 24 bit files are larger than 16 bit files.
