BTW if someone want to organize the next public test it will be great. It's not necessary should be me though I still will be glad to conduct public multiformat test at 100 kbps (probably next year ).
I'd prefer to see a trusted HA member with at least 2-3 years of registration. It would be great if Steve Forte Rio, Garf, /mnt or AlexB conducted a test since they always help to organize them. Maybe Sebastian Mares would like to come back

How about 48kbps HE AAC ? Or low bitrate multiformat with few HE AAC encoders and Ogg Vorbis and possibly some other format included ?

Well, the last time we have tested LC-AAC encoders at 96 kbps to pick up most optimal of them to include it into the future multiformat test at the same bitrate (96 kbps). This public test (multiformat at 96 kbps) has the highest priority (unconditionally) for me and I'm willing to conduct it in future in case if there won't be another volunteer/organizator to do this test.

Obviously if someone will want to organize public test at different bitrate then it will be up to him/her or other members as well. Anyway some members (me too) will help in any scenario.

Can You say when your encoder will be ready?

It is ready and should be public within a week or two.

What about 64 kbps? Last FhG HE-AAC encoder doesn't have setting for 48 kbps but 64 kbps.

The last 64 kbps public test is already partially outdated due to new FhG HE-AAC and your new upcoming Dolby HE-AAC.

Volunteer to conduct it?

Dolby Pulse is finally out. I'm afraid I don't have experience nor skills to conduct a public listening test. I rather trust it to specialists.

Anyway, I will support if anyone else is interested conducting a new HE AAC test. I am interested to see how the new encoder included with my product really is performing against Nero, iTunes, and Fraunhofer.
