32bit in Reaper question
Twenty8:
I use a MixPre 6ii. I record 32bit float/48kHz. I bring the polywav file into Reaper. I explode the polywav to multi-track... and away we go on processing.
My question is:
Do I need to apply dither to my renders? I am rendering to 24bit/48kHz wav to later make flac in TLH. Do I just need to apply dither if I make an additional 16bit/44.1kHz copy?
jadedphan:
i always dither, rather than just let the software save or convert while saving ....
Twenty8:
I don't think I ever noticed that after I explode the polywav in Reaper, the tracks are still 32 bit. How I did not know this was native behavior is an oversight, even after 6 months of taping shows with it.
My thinking was dithering was always for rendering kHz rate and not about bit rate so I have only dithered when moving from 48kHz to 44.1kHz when making a "lite" copy for some of my friends' bands.
aaronji:
It is my understanding that, when reducing bit depth, best practice is to dither to reduce distortion due to quantization error. I don't know whether it is strictly necessary, but it is easy to do, so why not?

The terms typically used for these two different processes are -
dither - changing bit rate
sample rate conversion - changing sample rate
Here's a good non technical article from Izotope on what these processes are and when they should be used - https://www.izotope.com/en/learn/what-is-dithering-in-audio.html
