Does anyone know of any good techniques for making pure tones from samples of records and the likes? I'm trying to chop up bits of jazz and classical into tones that loop seamlessly for as long as I want. The problem is I can't seem to get it seamless at all. I'd really appreciate any help with this....

i just occasionally mess around with this stuff, but what program do you use? i know with ableton you can easily do this by controlling the loop points of the sample, so it plays round the loop points when you hold a key down. It lets you blend the start and end of the loop quite seamlessly with a little fiddling around. You can do all sorts of things with the sampler in Live. You can pretty much tweak the samples like how you design sounds on a synth.

what do you mean by pure tone?

if it's just a case of making a sound loop seamlessly then you need to find the zero points where the amplitude is at 0.

was just looking for an image to show you and found this article

I've had a messed around with this a little bit, the longer the snippet of audio you'll want to use obv the much harder it will get to matchup. You can do things like getting it to reverse when it gets to the end as opposed to looping from start to finish. From what I can tell the trick is to keep looking for cycling points at different zooms and making sure you are cutting it at the end point of the cycle and not in the middle, untill you are all the way down to the null point where it crosses the 0 amp line.

Or try messing with some granular synthesis, this is a great piece of software http://xenakios.wordpress.com/2011/11/07/hourglass-0-8-5-release/, worth checking some YT videos to get an idea of what it can do

Yeah thanks guys. By pure tone I mean one that can play without you noticing any loop. I've only really been using sound forge for it.

I guess one of the problems is that you very rarely get a single note playing on a record, so it's difficult to pull out bits that you can have playing without some kind of noticable artifacts. Also samples with loads of notes are just a bit less easy to work with.

I'm trying to make sort of droney tracks where notes will slowly build up and overlap into different chords etc. I don't want to use synths but have a natural kind of sound. Don't want to swamp the tracks in reverb either... I guess it's quite specific what I'm asking, thanks for the thoughts. I should really try and mess about with proper samplers for this, rather than sound forge which is more of an editing tool.

Cheers.

There is definitely a way to do this in Kontakt. It lets you find the zero crossings automatically for the loops and also let's you set the amount by which the end and the start of the loop overlap. The shorter is the cycle of the sample that you sample the "purer" the tone you will get, but that's essential granular sampling, where you're taking really tiny portions of the sample and looping them. Take a look at some of those granular synths that come with Reaktor, I think those will let you do drone type stuff quite easily, also doing all sorts of movements across the sample, that's what they are made for basically.
