My name is Alexander Petrov-Savchenko and this is my personal website dedicated to the software audio effects. Currently I'm employed as a software engineer in a large international company, but in my spare time I do my own research in the digital audio field. My interest in digital signal processing began back in my university days and was a natural extension of my hobbies - music, electric guitar, programming and my math backgroud. Prior to exploring the digital sound domain, I've been making custom guitar stompboxes, so faithful modeling of analogue equipment is one of my primary goals.
I've been researching different DSP techniques and their applications to musical effects for quite a while, but I have never publicly released any of my works. This changed when I've discovered that KVR Audio forum is holding a so-called developer challenge - an open competition of audio software developers with community-driven prize fund and voting system. I decided to enter the contest with the alogorithm I've been working on at the time, so the SoftAmp 3OD VST plug-in was born. I didn't win anything, but I've received an invaluable experience and a ton of very positive feedback. That was the turning point for me and now I'm set to release all the stuff I make. Everything on this site is available for free and the plan is to keep it like this.
A single triode stage circuit typical for guitar preamps is captured in this plugin. The model engine is based on a system of non-linear ODEs. Some smart calculation techniques are used to reduce the .....
SoftAmp GT is a virtual emulation of a well-known analog guitar amplifier simulator stomp-box. The prototype is a solid state circuit that uses op-amps to saturate the signal and moderate filtering .....
CharBooster is a composite overdrive effect tailored specifically to be used as booster in front of any virtual amplifier model. It essentially consists of a pre-emphasis filter section designed to .....
