Studio One provides truly high-resolution audio, recording at sample rates up to 384 kHz with 32-bit floating point resolution. Studio One Professional can operate its mixer with 64-bit floating-point, double-precision processing. Studio One's audio engine automatically switches to 32-bit mode on the fly for 32-bit plug-ins, and runs in 64-bit mode for 64-bit plug-ins.
最好是用64 但必须是64系统64插件才有用
