Notes by Lex Toumbourou

Bit depth in digital audio is the 2nd key factor, next to Sample Rate, that determines the quality of sound in a digital audio recording.

Bit depth refers to the number of bits used to describe the amplitude of these waves at each sample point: the higher the bit depth, the more detailed the amplitude information, resulting in a more dynamic and nuanced sound.

Common Bit Depths:

• 16-bit: Standard for CDs, offers a good dynamic range for most listening environments.
• 24-bit: Often used in professional recording studios, providing a greater dynamic range.
• 32-bit: Mostly used in audio processing and mixing for its high precision and headroom.
