What is the dynamic range of 24-bit audio?

The dynamic range of 24-bit audio is indeed 144 dB. This dynamic range is derived from the fact that each additional bit doubles the number of possible amplitude levels for audio signals. In 24-bit audio, there are 2^24 possible values, which results in a theoretical maximum dynamic range of about 144 dB.

This means that 24-bit audio can capture extremely quiet sounds as well as very loud sounds without distortion, making it suitable for high-fidelity recordings. The significant dynamic range is a crucial aspect of digital audio because it allows for more nuanced and detailed sound reproduction. The higher the bit depth, the more variations in volume can be accurately represented, thus allowing for a richer audio experience.
