The flanging of regular doubles comes from frequency dependent phase cancellation. You can phase cancel pure sine waves by offsetting one signal exactly one cycle. But a complex signal -- like a Jeff Mills track -- is continuously changing, and slight offsets mean some frequencies cancel, and some frequencies reinforce, so you get a comb filter effect. What's REALLY interesting to a record geek like me is taking two different records that are similar enough to phase cancel. Chic's 'GoodTimes' and Sugarhill Gang's 'Rapper's Delight' are like this -- RD recreated the Good Times loop so precisely that when you line it up it flanges with the original.

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.

It's a real phenomenon -- if you combine two signals ] they can interfere with each other -- technically 'phase cancellation' ] such that new tones become audible. This question is a little diverged from this topic, but when talking about phase varience and "interference", I have the following question: Has anyone ever produced any double vinyls of the same track with a1 being a particular track and c1 being the same track, but with the inverted phase wave? 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. Kieran.

I once saw this list called "you know your a raver when..." and it then listed 101 reasons you could tell your a raver. Well, some people might be offended to be called ravers, I for one dont generally call myself one, but for some of these reasons you could easily replace raver with "techno freak" or something along those lines. Anyway, amongst others, there was one that said "you know you're a raver/techno freak when you find yourself nodding your head to the tribal sounds of a washing machine". Maybe this isn't toneshifting as discussed on the list, but its definately a case of a bored mind projecting music onto something which isn't necessarily musical, and I find it to be quite true. Sort of like working in factory's, many times have I considered taking my MD recorder to work with me to try and capture the seemingly musical hum and machine noise that is the background noise of a busy factory.

Taking the toneshifting phenonmenon to its logical extreme, if you sent enough emails to Johanna Thompson would they eventually begin to generate autorepsonses? Sorry. I had to do it. Just had to.
