Question: Hi, a question about dither...so lets say Reaper calculates 64 Bit float internally. If you render a 24 Bit wav file in your final export - is dithering needed or is this automatically applied inside Reaper? Or are things (Bit depth of audio and bit depth of Reaper calculation) not related at all?

    Technically you do need a dither when rendering to 24-bit, and you can apply this in the render dialog.

    In reality though, given the state of noise in converters, etc, for 24-bit, dither is pretty pointless. Having some noise around -140dB is just never going to be an issue.

    In summary: dither is more important as the low end of the dynamic range becomes more audible. For 8-bit audio, dither makes a HUGE difference. For 16 bit, it makes a small difference. For 24 bit, it makes a VERY VERY small difference.
