What is it?
Sprak is a noise/drone synth designed to make phat and gritty ehhrm, noise and drones. While we love the existing noise and drone apps available on the app store, none of them combined the two in that special way we had a craving for. So what did we crave?
* Phase realign
* Gritty sound
* Something you could take pleasure from exploring.
* Being able to get new and interesting sounds
* Distortion, two cup fulls!
* Being able to feedback the sound back into itself, ahh yeah, nice!
* Easy on the eye.
* Borrow aesthetics from DIY pedals and Circuit bent “stuff”.
That’s about it, we like to connect a headphone and sit in a comfy chair and just play with the knobs and zone out.
In one sentence: Phat-noisy drones in an iPhone app.
How do I use it?
It’s dead easy really, real easy, just turn the knobs and you’ll get new and exiting sounds. If you still want to know what the knobs and levers do, press the little ? up in the left corner and there will be an overlay of the parameters.
Did you try turning several knobs at the same time? Big knobs change things much, smaller less.
What is it really?
Ok, so I see that you are really interested in softsynts and synthesizer engines, so I’ll go through it with you. First of the oscillators are based on the cubic hermetic spline. Those splines are awesome because you can just set points out that they pass through, instead of just near. there are 64 parameters per oscillator to control, and that is done by the sound-knob (big ass top left knob) . How about that Huh!
Then the audio splits and adds to the feedback from last sample at the volume set by the slider. and it also adds with another oscillator per channel that is just like the first one, but on a slightly different Hz so you can get it to drone. We’ve found that the volume of the second oscillator per channel really needs to be tweakable to get awesome results. The distortion is an overdrive type distortion, but we’ve tweaked to make it behave in a usable way.
Oh and the lowpass that we put on everything when you press down on the speaker adjusts when you drag your finger away from the center. Try it!
