VS 25: Akaizer Tool

Hello. Transforming a sound into something totally new is pretty cool. Just like taking a bunch of sounds and transforming them into a new track. But when you have so many options at your disposal it’s easy to get lost and come up with something that’s a little too complex or abstract for a listener to relate. And if you have some OCD tendencies like I do, things get only worse.

So I am a sucker for simple and effective ideas. Something you can apply in a few logical steps and perhaps combine it with another simple trick and get something that works easy and nice. CDP’s Blur process is a great example for this. It yields decent results in a relatively short time with a single step process. When you add some extra spin on it, something fundamental like reversing the sound or filtering, you usually get something pretty dope.

I’ve recently discovered that Akaizer can work in a similar manner. It’s a standalone tool for doing old school Akai style timestretching and it can also run inside Renoise as an extension. (Yay!) It’s pretty good for creating usable sounds out of even very basic samples so I’ve picked it for this post’s main subject.

Download this post’s Renoise project file here.

Let’s get started. The sound I have is literally the first sample I found as I randomly browsed my sample folders.

Running the Akaizer tool is simple once you install it by drag & dropping into Renoise. Just right click the sample in waveform view and select “Process->Akaizer”. It has a few options: “Timefactor” is the amount of stretch, you can control the granularity by “Cycle length”, and “Transpose” transposes everything up or down. All these can greatly influence the output so feel free to play around. There’s also a classic algorithm which you can throw in as an extra flavour. In this case I just upped the timefactor to 1000% so it’s ten times longer than the original. Looks like this.

Next step is filtering. I’m using a lowpass filter here (with some resonance and drive) that closes quickly so it ends up as a plucked sound. There are a lot of options here depending on the filter and envelope types you choose.

And that’s it. A simple plucked synthlike sound you can use in at least a few different ways. As a quick example here’s a silly melody with some added effects and filter automation.

And that concludes this tutorial. I hope you find it useful, let me know what you think in the comments below!
