Which audio bit depth is commonly used in Pro Tools sessions?

In Pro Tools sessions, 24-bit audio bit depth is the standard commonly used. This level of bit depth provides a significant advantage in terms of audio quality, allowing for a dynamic range that can capture more subtle nuances in sound. With a 24-bit depth, recordings offer greater fidelity, enabling a more extensive range of volumes—effectively capturing sounds from very quiet to very loud without introducing distortion. This makes it ideal for professional music production and audio post-production, where the preservation of audio integrity is crucial.

While 16-bit audio is used in consumer-grade formats and some specific applications, it does not provide the same level of detail and dynamic range as 24-bit. Higher options like 32-bit and 64-bit are typically used for specialized applications, such as internal processing in digital audio workstations or for specific plugins, but are not the common choice for standard session recording. Therefore, 24-bit remains the industry standard for high-quality audio capture in Pro Tools.
