A surround sound processing technology that can extract center, left, right, bass and stereo surround channels from a stereo source. Pro Logic IIx can additionally extract two rear surrounds from either stereo or 5.1 sources, and Pro Logic IIz further extracts front stereo height channels.

Multiple modes may be offered by the system: Movie mode, Music mode and Game mode.

PLII works fundamentally as a matrix decoder with servos that accentuate the directionality of the current determined dominant signal by negative feedback in the other channels. The surround channels are fed by signals of inverted phase while the height channels contain uncorrelated, ambient signals.

Although PLII works from basically any stereo source, stereo programmes can be specifically encoded for surround decoding by PLII with matrix encoding. These programmes may be branded with the "Dolby Stereo" or "Dolby Surround" logo.

DO NOT believe Eazy-X's definition. It sucks so bad.

"This song is encoded by Dolby Pro Logic II!"
"No, Pro Logic II is a decoder only."

murderhobo

In a tabletop game, a murderhobo is a player who murders NPCs indiscriminately. This is normally derogatory, referring to a player who totally ignores quests, dialog, backstory, trade, world building etc.

The term is most common with Dungeons and Dragons, but it can be applied to most RPGs where the player is allowed to kill most quest-giving NPCs and NPC traders. E.g. Elder Scrolls, Fallout, Divinity original sin.

Whale

In sales terms, a whale is a prospect that is significantly larger than an organization’s average customer.

Whales are large and extremely difficult to close. Due to their immense size, they are highly sought-after.

A whale is typically identified at first by a whale hunter on the sales team, but often requires cross-discipline participation in order to close; this includes assistance from operations, engineering, creative, client success, and business development teams.

"Shit...the sales director chewed me out on the sales call this morning. He's totally pissed that I have nothing in my pipeline. I've been focused on this one whale for so long that I haven't had time to prospect for normal-sized deals."

city chicken

A food native to Pittsburgh/Western Pennsylvania in which cubes of pork and/or veal are put on a short, wooden skewer, breaded, then baked and/or fried.

I've heard that city chicken originated during the Great Depression, when folks didn't have enough money to buy full cuts of meat, so they assembled meat scraps on a wooden skewer, creating a make-shift drumstick. Hence the name.

Are yinz havin' city chicken for dinner?
