Default Dithering Question

I've been doing some research on dithering and I'm still not clear.

I have Pro Tools 12.4 and I recently finished a song I wish to bounce to .wav. My last plugin on the mixbus was ozone and dithering is turned off. When I go to bounce to wav in Pro Tools it gives me the option to select 16 bit. I selected it and all seems fine, but I always hear how you are supposed to dither with a plugin. Maybe that is old news and the bounce in Pro Tools 12.4 takes care of it?

In other words, when I bounce to .wav, is selecting 16 bit in the Pro Tools bounce to disk options enough? If not, what do I need to do and why? The bounced 16 bit .wav file sounds fine.

Thanks!

While using Bounce to Disk, use a dither plug-in any time you are reducing bit depth... read more in PT 12.4 Reference Guide, page 1036

Interesting. I will definitely have to enable dithering in Ozone and bounce down again and see if I can hear a difference.

This whole dithering thing sure is confusing. Maybe I will search some youtube videos for an explanation.

Thanks!

What's happening with the final WAV file? You should keep everything 24-bit until the last possible moment. In my case my CD authoring app, soundBlade, does the dithering and 16-bit conversion for me when writing the PMCD master or DDP fileset.

If you're converting to MP3 or AAC, most good conversion programs can also add dithering and bit conversion at that point.

For MP3, I just always choose to bounce to mp3 within Pro Tools. Never done anything else in regards to mp3. Is it not good to use Pro Tools to make the mp3?

I was wanting to give my friend/client a .wav copy and I've always been told that needs to be 16 bit. Which is why I was asking about dithering. What they will do with the .wav file, I have no idea. I just wanted to give them a .wav to use where they can instead of a mp3. They might print to CD and from what I know, I believe that needs to be 16 bit.

Thanks!

I typically track & bounce @ 24/48 wav. If an MP3 is needed, I use iTunes to quickly convert the 24/48 wav bounce to MP3 @ 320kbps - i.e. no need to re-bounce as MP3. To burn a CD (rarely anymore) I simply pull the 24/48 wav bounce into Sony CD Architect and use Sony Dither (or similar) to convert to 16/44.1 during the burn process - i.e. no need to re-bounce as 16/44.1.

WAVs don't need to be 16-bit... keep it at 24 and if they want to print to CD, then they'll need to dither. Most burning software has selectable dithering built-in.

However in response to EGS:

iTunes doesn't do any dithering when creating an MP3. You should just let it handle 16-bit files, in my opinion.

There are a few great programs to do encoding, which I'd recommend over iTunes. One of them is dBpoweramp:

https://www.dbpoweramp.com/

It's a GREAT app and has lots of encode/decode options, also allowing you to add DSP ahead of the encode to do things like sample rate changes, 24 to 16 bit conversion, etc. Well worth it's price.

I also tend to encode mixes to a lossless format, like Apple's ALAC or FLAC (Windows and 'hip' Mac users). The file sizes are HALF or less than WAV and there is no loss to the original quality!!

What exactly happens when iTunes converts a 24/48 wav to MP3 at 320kbps? Any definitive tech info on how iTunes handles this task? Thanks!!!
