When both a1 and c1 are perfectly mixed, the inverted and normal waves should totally cancel each other out, and there should be (in theory) complete silence. Yet, as soon as they are pitch shifted/slightly out of phase, then the tune(s) should jump in. Just wondering, it would be an interesting experiment. ___________________________________________
Unfortunately this only works under extremely controlled situations ie. perfectly noiseless mixing console with no pre-amp, truely matched needles, noiseless, distortionless amp with no pre or post digital amplification. More on the topic of toneshifting (actually a physics term coined long before darw_n). Toneshifting in the darw_nian sense, could be explained or perpetuated in two ways: 1. Take sense enhancing drugs This will enhance your senses such that any reverberations from the room you are in, along with the mindless chatter of hundreds of people will construct interesting new wave forms for your ears. 2. Be in a small group of people in a large auditory space, and stand at the extremities of the soundspace. Up close to the system you will find your ears drums lock up and sound transmits through you (you are in fact standing before waveforms of up to 3000 Hz can form, therefore you only hear a small portion of them (resonant form) and then any reverberation of that sound. Away from the system you will hear more tones as waveforms cycle fully before hitting you, but they also reverberate of other walls and such, enhancing your experience with all sorts of phantom sounds (ie. music reverberating off of pipes and stages etc.) I spent a long time thinking about the "mental projection" aspect of darw_n's theory, but this is nothing new. We have been mentally projecting on music since we were born. Point in case John Coltrane's "Blue Train": I have a friend who used to listen to this album in the morning when he woke up, and he said it was the best way to wake up, it refreshed and invigored him, while I listened to this album fully through a break-up, and it makes me sad to hear it all the time. As for Richie playing emotionless music, this isn't true at all, he's simply not playing soulful music ergo your friends comment 'Richie has no soul'. Listen to DEFX909 again, there are tonnes of get up and party tracks on there as well as a fair amount of moody music. ----- Original Message ----- From: "Kieran" <[EMAIL PROTECTED]> To: "Kent williams" <[EMAIL PROTECTED]> Cc: "313 list" <313@hyperreal.org> Sent: Monday, January 08, 2001 9:36 PM Subject: Re: [313] tone shifting > On Mon, 8 Jan 2001, Kent williams wrote: > > ] In the context of DJ-ing, tone-shifting is what happens when you mix > ] two records and new music emerges from the the interference between > ] the two tracks.
