New Public Multiformat Listening Test (Jan 2014), Discussion

[IgorC]

Kamedo2 is working on it now.

MPEG sequence, short. I don't know the title, and the name section is just for the convenience.

OK. Now about a number of samples. It should be a high number. 40-50. Most of us here on the same page.

Wow. That sounds very tedious. How much time will be allotted?

The test will be open during more time. It's always possible to prolong it.
And it's not obligatory to submit all results.

Well, now I'll start gathering selected samples and preparing them for encoding.

I propose to normalize all samples to -3 dBFS  before encoding. Also this should help to prevent insufficient loudness during the test, if some samples will be too quiet.

Random pick from SQM selection - glockenspiel

[darkbyte]

I can't find my sample. But even if it's left out that's already a huge amount of samples

[IgorC]

darkbyte
Oh, I don't see it neither. Probably we have forgotten to include your sample. Sorry about that.
Anyway some picked samples aren't online anymore. We should probably perform some additional random selection to replace these missing samples and include your sample this time.

[IgorC]

Picked samples.

3 samples aren't available anymore. So additional random selection will be done. darkbyte's sample should be included in a list of possible samples.

Personally I like the set of samples. The samples are heterogeneous.

[kamedo2]

Which 3 samples? I haven't seen the 164 huge set of samples nor the Chris's samples, but all the other picked samples are here, ordered and saved in my harddisk.
