Tbh, if you're editing, remixing, etc, 32-bit float at higher sample rates obviously make sense. But not for a final delivery, and not for your playback devices

Tbh, if you're editing, remixing, etc, 32-bit float at higher sample rates obviously make sense. But not for a final delivery, and not for your playback devices. Even when I edit 192kHz 32-bit float audio (e.g. for a slow-motion video sequence where I need to slow the audio to match) my playback setup still only supports 16-bit 48kHz (and I don't need more).
