Apparently all you need to do is knock on Michael’s door and he’ll take you in.

Sorry, I was in a hurry to leave home so I misspelled ’an’ as ’and’ -- the post should read: According to Wikipedia, an ’audio signal’ is an analog or digital representation of sound. https://en.wikipedia.org/wiki/Audio_signal Loudspeakers take an electrical audio signal as the input, create a vibration, and produce the sounds you hear. Microphones do the opposite. So there are three things, sound, vibration, and signal, and two forms of signal, analog and digital. Oscilloscopes take an electrical audio signal as the input and produce the moving visual image that you see. |
In the last hour I have put slivers of wood, up to 1/4" thick on the tops and bottoms of the springs. Much more girth and impact to the notes. Drums and cymbals are taking on more 3d shapes and the tone of the mid highs are rolling across the cymbals then come to the end of the cymbal and rolls into the air. So to recap the springs on their own didn't do it with the other materials in the components. Then springs with the added tone from the slivers moves things a lot closer to real instruments sounds. A couple more hours and I will go LTR Tuning Blocks, but the springs and wood is very listenable. I can move the position of each spring to get a different tonal transfer. Pretty fun couple of days going back through these procedures again. Makes it fun to have a stereo to play with and hear the interaction of the entire space. I added a thin slice of rubber on the bottom of the slivers under the spring and the sound went instantly dark and rubbery. Tried it on top, same thing. Not something I am hunting for so the rubber again sits on the sidelines. I also briefly put back in one of the players I added Geoff's NDM to and it was disaster. I can best describe this as a stage filled with black holes. I quickly put back in the non-treated CDP and in about 3 to 4 minutes the stage came back nice and full. I think the NDM can sit off to the side for a while as well, not really sure I'm going to go back that direction for a couple of reasons, meaning a couple other types of material that I like better on the tray. However the experiment with the NDM was not a complete wash. That's for another topic perhaps but after some further experimenting is done. Ok, some more listening and I'll be back. MG |
