I've tried a couple times, but nothing happens. Tks. ......................... There are reasons to support 32-bit data. The emerging network standard is based on a 32-int pipe (AVB/Dante). Dante now has over 200 licensees. Higher dynamic range hardware and plug-in products are in the works. It won't be long before the 24-bit barrier is commonly exceeded in certain devices, though I agree with others here who point out that real-world <systemic> dynamic range will likely remain under 20 bits (room => mic => pre => ADC => DAW processing => delivery format => DAC => analog stage => amplifier => speakers/HP => room noise) I believe Reaper and Audition maintain lossless 32-int within a 64-float engine, with more DAW makers to come. And as some have noted, there's movement towards 32-bit audiophile delivery. FLAC should be the 32-bit delivery format of choice. > > On Sat, Sep 26, 2015 at 10:36 AM, Martijn van Beurden > <mva...@gmail.com> wrote: > > > * This is nuts. 24 bits has a dynamic range of ~140dB which is roughly > > the difference between a quiet whisper in a quiet room, to > the sound > > of a jet engine at 10 meters.
