Contents .DMG to unpack the full (55GB) library + bonus patch that fixes Sabian AAX Hihat samples in ambient mics problems. Differences between the BFD2 boxed version and the download version? The data in the download version has been reduced to 20-bit audio, whereas the boxed version contains 24-bit audio. The download version is only supported on Windows 7 and Mac OSX 10.5.8 or later, and is only compatible with Intel processors on Mac. How large is the download version? The download size is approx 14GB – this is uncompressed during installation resulting in a maximum installed size of approx 52GB. Why has the data been reduced to 20-bit for the download version? 20-bit audio offers a dynamic range of around 120dB. This is greater than the dynamic range of most professional-grade preamps/A-D converters, so there is no perceptible loss of audio quality. Any noise introduced due to the bit-reduction process is well below the analogue noise floor inherent in the recordings, and leads to much smaller downloads.
