Okay, by request, I've put up the Pasadena Pulse Audio V2 Beta 2 settings up on my blog.

@blackmzungo You can now get them at that link.

@DirkVoorhoeve Checking.

Thanks for the brilliant work on audio guys, it's now included in all testing of Sedna matrix 'Orion' setting. Hopefully we'll have a release over the next day or so...

@rajamalik Those are indeed the settings he means and thanks for the compliment.

@thepalalias ya ya setting ;) he he,.. oops

@thepalalias yep i understood,.. no problem u r my best friend,.. i dont mind,.. i just concluded that orion v4b does well with the v2beta audio setting even at 448kbps...i thought it would be useful to share the info that it is good and tested,..

@thepalalias

I really suggest to move all this good work to our wiki section. So, people could edit this.

@thepalalias please do use and edit my summary and use it in the initial post or on the wiki! Formatting can be done with Markdown I think.

Thanks @thepalalias for all your efforts. This info is of great help to me as I'm keen to get good audio off the GH2 and had to do a bit of testing myself to get somewhat (but not always) acceptable results.

I regularly use two mics with the GH2, a Rode NTG-2 shotgun and Audio-Technica AT822 stereo mic. Both of these can be powered by an AA battery.

I have a Sound Devices Mic Pre for my phantom power needs, but I found out when I ran the 'line out' from the preamp into the GH2 the levels were terribly over driven, even at '1'. Using battery powered mics with lower output signals however seems to work fine.

This is a simple test using your 'Pasadena Pulse Audio V2 Beta 2' settings (in conjunction with 'cluster'), with my 2 different mics. Each setting runs for 10 seconds. The main thing I noticed was the sensitivity in levels between '4' and '3' was quite big compared to 3 > 2 > 1. The general ambience was not so loud however so this may not be an issue. Otherwise its much improved over the stock settings to my ears.

@MirrorMan Yes, the sensitivity difference between Mic Levels 3 and 4 is significantly larger than the other differences because level 4 is designed to get you maximum level when sounds are so quiet that you have no use for a wide dynamic range but do need a lot of level.

The estimated level differences between mic levels are outlined on the blog for that setting at www.PasadenaPulse.net and may have been included in this thread as well.

The increments have to be a compromise because there are only 4 mic levels across at least 38dB of gain difference.

@thepalalias yes, I thought in cases like this, having 5 or 6 levels would be more practical, but oh well...

Now that I more or less understand the Decimal sensitivity scale I'd like to make some slight adjustments for my own use and test them. Will get back to you on this. I also have other mics I'd like to test. If we get this up on the wiki, it would be good to have a list of good mics and settings for the GH2.

I also realized that if someone wants to combine your audio settings with other video settings, they can click the preset, load your audio values and then click a second present and load those values. I noticed it keeps the first preset values for the audio settings. All you have to do is check the boxes in the audio section and turn them on.

Not sure if @Vitaliy_Kiselev planned the preset system that way but it works. (I'm sure he did, he can do it all, right?!)

@thepalalias & @MirrorMan

I believe they do. You load Pasadena Pulse Audio and then you "Alt+Click" to load your merger. The settings that are checked on Pasadena won't be imported from the merger. I do that a lot with my 24h Timebuster settings.
