Pro Tools 11 supports recording at bit depths up to 32-bit floating point, which allows for extremely high dynamic range and precise levels of detail in audio recordings. This is a substantial improvement from earlier versions of Pro Tools, which typically supported 24-bit or lower bit depths. The ability to record at such high bit depths is particularly important for professional audio work, where even small variations in sound quality can be noticeable and significant. Additionally, Pro Tools 11 supports a wide range of other features and tools for audio editing and production, making it a popular choice among musicians, sound engineers, and other professionals.
