Currently Nyquist plug-ins do not have read/write access to label tracks :( otherwise the plug-in would be done already.
I guess that this is my vote for giving Nyquist access to label tracks.
As well as mine.

Re: Audible.com QC standards

Thanks, Voodoobones, for your perspective. Don't judge the gift by the paper it is wrapped in, however. I know that it gets sometimes pretty technical when Steve and I exchange our opinions. Nevertheless, it is part of the abstraction and simplification process. Our goal is always the ease of use fo...

Re: Has anyone found a demodulator for CD4 (Quadraphonic) Vi

At least the "sum and difference" part is easy ;) (it's about the only part that is) Yeah, but only if the direct signal (with about 40 ms delay) and the demodulated signal can be properly synchronized. The low-pass and band-pass filters, along with the equalization and compander section ...

Re: Has anyone found a demodulator for CD4 (Quadraphonic) Vi

Hi Tim, Steve was so kind to introduce us presently. I'll try to support you in the plug-in development. Firstly, I must familiarize myself with the cd4 stuff. Unfortunately is none of your provided material accessible for screen readers. Hence, I must do some OCR with them. It's certainly a interes...

Re: Getting a full and rich voice

You can try this following equalization. Copy the text, open the effect menu and choose "Nyquist Prompt". Paste the text into the textfield and press ok. Is that better? (eq-band (eq-band (eq-band s 200 12 4) 4000 3 1) 650 -8 0.6) I'd say you've a beautiful voice if the low end is properly...

Re: Audible.com QC standards

Thank you Steve, this clarifies a lot. I'd prefer a integrated long term compressor for this blocks, in addition to the labels, but that's only a subjective point of view. You'll include the RMS/Peak values in the label text, don't you? The following pauses seem to be fixed for a Audible audio book:...

Re: Audible.com QC standards

Audible prefers Audio that is RMS-normalized at -20 dB. The peaks should "hover" around -3 dB. As you say, Steve, there may well be peaks that go up to 0 dB. Exacting people can then use a peak-limiter to strictly go for the -3 dB. As I've said before, the mp3 conversion alters the overall...

Re: Audible.com QC standards

Intrestingly enough, the exported mp3 (constant, 128 kbps, librivox standard) shows a peak of -2.5 dB after import--instead of -2 dB. Hence, mp3 conversion does not necessarily decrease the head room (i.e. increase the peak). The offset seems to be nearly constant: 0 dB > -0.5 dB -3 dB > -3.5 dB -20...
