So now THIS is the proper way to BTD???

[fingerz88d]

I found this little diddy on the DUC recently and wondered if any of ya'll operate this way:

"Here are the two scenarios. First with out sample rate conversion the second with."

1. (Dither to 16-bit on master fader) -> (Bounce to 16-bit)

2. (Dither to 16-bit on master fader) -> (SRC 48 to 44.1) -> (Bounce to 16-bit)

In the first case the dither is the last operation is the signal chain, so all is well, but in the second case the SRC is the last signal processing element in the signal chain (the results of which will be truncated by the bounce to 16-bit).

To get around this problem I recommend:

(SRC 48 to 44.1) -> (Bounce to 24-bit) -> (import back into PT) -> (Dither to 16-bit on master fader) -> (Bounce to 16-bit)

I know this is a pain, and we'd like to improve the workflow at some point, but I think this is currently the best option.

So...anyone doing it this way? Is this something that's been common knowledge and I just missed it somehow?

Your thoughts?

My thoughts?

Why record at 48? I don't hear any appreciable difference between 48 and 44.1, certainly after bouncing to 16 bit. I just stay 24 bit 44.1 KHz throughout the session and apply dither on the final bounce, most often in T-RackS...

I generally try to record at 48k and then use the Waves L2 to do both (SRC and dither to 16-bit) simultaneously. I never considered that there would be a difference.

I'll have to give it a try to see if I hear a difference.

Anyone else?

hello, i record in 24 bit/44.1 khz, so i bounce in the same. i later set this to 16 bit for the cd writing only.
i use the batch converter of spark for this. i master with 24 bit files. (not in protools)
for my work i use wavelab 4 (i'm a freelance mastering engineer) and the dithering is very good in that program.
greetings, tantejo.

Don't get the DUC started on the whole 44.1/48 thing again...

Education and lots of it!

Most people don't understand that dither is necessary unless you are willing to accept edgy digital distortion that you can never get rid of.

Yes my friend, we're all aware of the neccessity of dither use...my question, however, deals with not being able, as far as I've gathered from the Digi tech specialist, to do a SRC and bit depth reduction (24/48k to 16/44:1) in a single pass for optimum BTD results. If you read my initial post, he states that a 2 bounce procedure would be required for the desired best product.

Anyone do an A/B yet?
