Dithering?

Yeah, what is it? I recently got WaveLab and I am in the process of learning it. I noticed there is a small 'Dithering' window in the bottom right corner. I read the 'Help' file and I understand the jist of it, I just don't know how to use it I guess. I would normally just record in 32 bits in Cool Edit 2 and then downsample to 16 bits. Does Cool Edit apply dithering automatically? How should I work out the dithering in wavelab? Thanks guys! Hey, maybe an entry for 'dithering' could be added in the Glossary since I did not find it there. Or maybe it's just something I should know ;-)

Jun 19, 2003 10:15 pm Ahh... Just record in 16-bit 44.1 and you won't have to worry about it (That's my philosophy, at least). Saves a bunch of disk space too. Hahaha. Well, whatever floats your boat :-)
Jun 20, 2003 01:09 am I'm running v3, so it you're on v4, it might not be the same, but in v3 the dithering function is part of the Master Section.
Dithering will change the bit rate of a wav file. Sometimes you might want to do this.
the Master Section is the 32bit processing section where VST and DX effects are applied. There's a master fader and some other options available. Generally you want to leave the dithering off, unless you're playing back say a 24bit recording and want to dither down to say 16bit for instance. Also used for permanently dithering to another sample rate when you apply the effects permanently. It's called "Apply" in v3, but I know they changed the name in v4, I just forget what they called it.

I would pesonally reccomend that you record at 44.1Khz, 16bit - then you will not have to worry about dithering or downsampling. The main reason I say this is because the algorythms present in Cool Edit pro will more that likley do nasty things to the audio.
If you really want to be able to record at higher resolutions, and then dither back down, I would reccomend the Waves' IDR plugin.
jues.
Jun 20, 2003 08:07 am I don't know the exact numbers off the top of my head but the bit rate is a function of relitive amplitude or volume. If you record at 32 bit then you have some astronomical number of amplitude slots for each sample. Each amplitude slot has a very small amplitude bandwidth. This is an exageration but lets say one sample has a volume of 40dB. It will be recorded in a slot that ranges from 39 to 41 dB. Now when you mix down for a CD you are limited to 16 bit. That sample will now be recorded in a slot that ranges from 38 to 42 dB. Obvoiusly the resolution of that sample in 16 bit is going to be less accurate. Dithering is a process that minimizes the effect of transfering a recording from a more accurate set of samples to less accurate samples.
