The granular synthesis program also divides the sound into small segments or grains, but doesn't divide it by frequency.Įach plug‑in has a 'bands' control that governs this ratio. The number of frequency bands and the number of samples in each block are linked, so there is a constant trade‑off between frequency response and transient (time) response. The phase vocoder works by sampling the incoming signal and dividing it into blocks each block is, in turn, divided into different frequency bands. This is a collection of plug‑ins that use the Soundhack phase vocoder and granular synthesis algorithms to stretch time, shift pitch and distort phase. PvocativeĮrbe's new collection is the Pvoc Kit. The Soundhack plug‑ins are available for Mac, in VST, AU and RTAS versions, and as VST plug‑ins for Windows. So far, there have been three bundles, all containing plug‑ins based around similar themes: the Delay Trio, for example, contains a delay, a pitch delay and the enigmatically titled Bubbler. Since 2000, Erbe has also been spinning off the technology behind Soundhack in various plug‑ins. The original Soundhack program has collected many fans, from Trent Reznor to Ry Cooder, and its collection of filters and spectral manipulation techniques has been used on films such as The Matrix and The City Of Lost Children. Tom Erbe's Soundhack processors have been around since 1991, and are described on the company's web site as "Essential tools for adventurous musicians and sound designers”. these are the kind of things that just take a good day of getting your hands dirty (after spending a good week reading about the process and not getting it day after day, and feeling like a moron!).Soundhack's powerful algorithms can provide high‑quality pitch‑shifting - or sonic mayhem! pitch shifting, audio editing, formant shifting, etc. I can't afford a Pacarana, so until then, I process my cross-modulations offline in max.ĭo it by hand. Not because they're idiots or anything - it's just not very straightforward unless you understand the basic concepts behind it (Fourier Transform). Other than KSP scripting your own instruments from scratch, this is as close to Voodoo and black magic you can get in Kontakt - it would take a good few pages to walk you through the process, and most people just don't understand what their doing. you can use an AET filter, analyze a source sound, and apply the phase characteristics to another sound. lol fancy phrase for short term Fourier transform). It has a processing filter in it called an "AET Morph". The last option, which just sprang to mind, is Kontakt. If you're unfamiliar with DSP, and you don't have the cash laying around for a Kyma Pacarana, then chances are you'll have to do this by hand, with a LOT of resampling. Spectral convolution would work if you played with it enough, but the reality is you're looking at a lot of resampling, using a convolution reverb on the source sound - with the other sound loaded into a good convolution reverb program. That's what happens when you spend 3k+ on a box with like 16 multicore CPUs in it dedicated to audio though. Essentially the same thing - but it's in real-time, and incredibly high-detail. If you've got a few grand to spend, get a Pacarana from Symbolic sounds - and you'll have access to what they refer to as "Tau Morphing". then it's just a matter of loading the two samples together and using a UI object (like a slider) to morph them together. You don't need to necessarily know the hard math behind it, but understand what it does, and how to properly utilize windowing and bins in the context of MSP to get the sound you're after. you can either create a patch in max 6/7 using the pfft~ object, which can get a little tricky, seeing as you'll need to learn about the Fourier Transform. If that's indeed the case then there are a few ways to go about doing this. The "morph" you're describing is known as (both) spectral cross-modulation, and spectral convolution.įrom what i've read in your question, I gather you're interested in essentially crossfading the two sounds together, but in the frequency domain not the time domain?
