Album Publishing, process signal flow

Postby Plec » Fri Aug 23, 2019 17:09

Just wanted to have something confirmed regarding the Album Publishing tool and when you use different processes within it.

If I'm generating files from a 24bit MTFF, which are going to 24b WAV, 16b WAV, MP3 and AAC with SRC, dithering and gain changes applied. I would hope the process looks as follows....

1. SRC
2. Gain change
3. Dither
4. Encoding to the different formats

Can anyone confirm that this is the order of operation? I'd imagine it probably is but... don't want to miss anything. :)

Gain change?

Yes, you have the option of Gain post SRC for every delivery format you choose. Even not using any SRC you can still apply gain and this is excellent for producing different sets of masters without having to produce new masters from the timeline. If you're doing a CD master you can just create a PMI from the MTFF and lower the ceiling by 0.2db. If you're creating a streaming master you can gain those down -1db for instance and produce WAV, MP3, MP4 from that etc..

In such case the order of operation would be very important, and since it's Pyramix I gather it is.. but there's nothing in the manual that actually describes the processing order.

Ah, well, the manual...

Thanks for that tip about Gain Change - I had missed it completely.

As for the processing order, I would assume that in any event, Dithering is going to be the penultimate process, just before the selected file-type generation.

That just leaves which is the ante-penultimate, and which the pre-ante-penultimate...

SRC before Gain Change? Or the other way around? Or maybe both at the same time as part of the same operation?

Seems like a question for Merging Support, rather than here in the forum.

Actually, it's very important info to have here in the forum...

I will check to be sure and for now, here's my semi-educated guess:

2. Gain change
1. SRC
3. Wordlength Reduction/Dither
4. Formatting (LPCM) and/or Encoding(Lossless/Lossy)

Some SRC algorithms create overload problems, so very high-level signals are best avoided. The Hepta SRC in Pyramix seems (more or less) unaffected, so may be OK or only require very small reductions (-0.1 to -0.5) due to it's internal structure.

Again, above is speculation, for now.
