While studying sound engineering & acoustics and being a passionate programmer, so far I've developed some desktop apps(Java/JNI/C/C++) and one applet (Java & SQL), mainly based on speech intelligibility tests and designed for hearing impairment diagnostics & hearing aids fitting/comparison.My other software was for doing some extensive signal processing (for example, spatial filtering & beamforming with multichannel recordings ~ for my bachelors degree in acoustics) and other custom manipulation on audio data (C#, Matlab), but ~sound~ is not my only point of interrest. I like to code tricky stuff, not only sound-focused, and I'm familiar with other areas & API's like Qt, Direct3D, DirectSound, OpenGL, OpenAL, winmm or nvidia CUDA, so far due to my home-alone, hobby-oriented, non-commercial experiences. Always wanted to develop games/scientific applications/utils, but I'm open for any offer that could make the world a better place ;)
