Title: Output format questions
Post by: dtc on August 29, 2015, 06:44:22 am

"Added the sample rates 705600 and 768000 to the Output Format dialog."

Does this mean that MC now uses these sample rates as its internal conversion format, or are they just upsamples from 352K and 386K?

Does JRMC21 support anything higher than DSD128 via DoP?

It uses those rates if you select them.

Matt - it is my understanding that many conversions within MC go through 352K or386K internally before getting to their final value.  Is that not correct? I guess that has not changed.

No, I don't think so.  We run at a rate internally and the resampler runs first to get things to that rate.  No other conversions are done.

Thanks.

Is support of 4xDSD in DoP Format planned?


" When trying to determine the DoP sample rate needed to support a given DSD sampling rate, simply divide by 16:

(44100 * 256) / 16 = 705600
(48000 * 256) / 16 = 768000

The iDSD Micro supports the PCM rates of 705600 Hz and 768000 Hz. The whole reason for this is not the anticipation of 705600 or 768000 Hz PCM material forthcoming, but DoP. "

We'll give it a try.

Next build:
NEW: Added the output format "Encode as 4xDSD in DoP format" for 4x DoP delivery.
