Ended Carver C-9 Sonic Hologram Generator
Sold by Lolly & Pop's Custom Estate Sales
$125.00
For the audiophile that has everything! The C-9 is a stand alone unit that some have called his finest implementation of the technology. I've wanted to tinker with Sonic Holography in my own system ever since it was demonstrated to me by a friend, Mark "Basspig" Weiss in his incredible sound system.
The problem it attempts to solve is called acoustical crosstalk. What's that? For example the sound from your LEFT speaker is heard by your LEFT ear. Inevitably some of this sound is also heard by your RIGHT ear slightly delayed, otherwise known as acoustical crosstalk. This can cause some anomalies in our perception of the sound. Headphone aficionados don't experience this crosstalk at all as you can imagine, which is one of the reasons people love the sound of headphones.
So what does this thing do? The problem the C-9 solves is called acoustical crosstalk. The sound from your LEFT speaker is heard by your LEFT ear. Inevitably some of this sound is also heard by your RIGHT ear slightly delayed, otherwise known as acoustical crosstalk. This can cause some anomalies in our perception of the sound. Headphone aficionados don't experience this crosstalk at all as you can imagine, which is one of the reasons people love the sound of headphones.
It's basic function is to take a 2-channel audio recording and attempt to eliminate acoustical crosstalk between the speakers and your ears. The Sonic Hologram Generator does this by sending an inverted copy of the audio signal to the opposing speaker with amplitude and delay such that it actively cancels the crosstalk at your ear. This can create a similar effect to using headphones, only instead of the sound appearing only inside your head as headphones do, the sound can appear in front of you anywhere in a 180 degree hemisphere. When implemented correctly, it sounds incredible. For a very detailed explanation you can read about it in the patent here. Simplified in the diagram below the Lr and Rl paths get nulled out by producing an inverted signal from the opposing speaker mixed in with the wanted direct sound paths Ll and Rr.
