Ableton 3-Band Sidechain Compressor

In search for a multiband sidechain compressor solution for Ableton, I stumbled upon Jason Timothy's 29-band sidechain compressor. Jason's approach was good to some extent, but I noticed that the crossovers between EQ frequency bands are not "flat", ie. Ableton's EQ (Jason's EQ configuration of it, that is) emphasizes the frequencies that lie between the bands.

For an improvement, in my opinion, one has to use Linkwitz-Riley filters for perfect band separation: the frequency roll-off of those filters is perfect in the sense that the roll-off of a certain band, when summed up with the roll-off of adjacent band, doesn't emphasize nor attenuate the signal. (For a graphical explanation, please refer to this picture. "LR" stands for "Linkwitz-Riley".) Also, I believe that common multiband compressors use exactly this filter type, as do certain audio speakers, for audio crossover between the woofer, mid-range and tweeter.

By using Christian-W. Budde's Dual Linkwitz-Riley Filters VST I achieved just that: I separated the signal to Low, Mid and High bands and connected Compressors to each one, which in turn can be sidechained.

For example, this 3-Band Sidechain Compressor can be used for attenuating the bass line so that it doesn't clash with the kick drum too much.

Thanks to Jason Timothy for the initial idea!

Download it here. (Requires Ableton v8.1.1!)

Limiting apt-get download speed

create file /etc/apt/apt.conf.d/76download with content:

Acquire
{
Queue-mode "access";
http
{
Dl-Limit "25";
};
};

That limits apt-get to 25KB/s

Fellow geeks, help needed

I need s p a m, as much as possible, sent to [nohide]office@paste.rs[/nohide]
If you can include it on your weblogs and such in plaintext form, it would be great! If you are using reCAPTCHA, you have to use nohide BBtag. And no, it's not a real "office" mail, it's just used for spam filter testing.

Thanks!

And again: [nohide]office@paste.rs[/nohide]

this bug will soon celebrate it's 3rd birthday. it's marked as confirmed, high importance, and reported upstream (debian). are we going to do something about it, or are we just waiting for debian to resolve this?

(Emphasis added for extra lulz)

Veggie dry sausage-like cream cheese spread

By experimenting with a couple of ingredients, I have made a cream cheese spread that, at least to my senses, resembles the Serbian dry sausage taste a lot. Weird!

Recipe:

3 tbsp cream cheese ("A la kajmak" or similar)
3 tbsp yogurt
4 leaves of fresh basil
2 cloves of garlic
salt

Put the cream cheese and yogurt in a cup, cut basil and garlic into very small pieces and add them to the mixture. Stir well. Add salt to taste and spread over some nice wholemeal bread.

Enjoy!

XP Performance Edition: srpski keyboard layout HOWTO

Performance Edition Windows XP je uprošćena verzija XP-a koja ima poizbacivane gomile drajvera i nepotrebnih gluposti, ali nažalost izbačena je i podrška za srpski keyboard layout, ćirilični i latinični. Kako ispraviti? Lako.

1. Prekopirati sa regularnog XP-a (možda bi i w2k poslužio?) fajlove kbdycc.dll i kbdycl.dll iz C:\WINDOWS\system32 foldera
2. Uneti u registry:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layouts\0000081a]
"Layout Text"="Serbian (Latin)"
"Layout Display Name"="@%SystemRoot%\\system32\\input.dll,-5038"
"Layout File"="KBDYCL.DLL"

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layouts\00000c1a]
"Layout Text"="Serbian (Cyrillic)"
"Layout Display Name"="@%SystemRoot%\\system32\\input.dll,-5057"
"Layout File"="KBDYCC.DLL"

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Nls\Locale]
"0000081a"="2"
"00000c1a"="5"

Remove comments and empty lines sed one-liner

sed -e 's/#.*//' -e 's/[ ^I]*$//' -e '/^$/ d'

...so I don't have to think of it again.
