    Just an idea in between: A steam engine can be simulated when using a simple noise generator with LFSR-noise generator and modulation it's volume with a LFO and an overlay of an EQ emphesizing the...

    I am in the process to emulate engine sounds by modelling the mechanics of the metal and the environment. This most probably will nothing a small micro processor can synthesize in real time, but i...

    Let's say noise cancellation but before the noise occurs. The problem is the tricky behaviour of the engines and gear boxes with their reflection of torque impulses and transformation of the...

    FFT is not the best approach. It lacks precision in the lower frequency range. I am using a DFT with optimized frequencies, but it works in an FPGA with tight frequency distance settings, so it...

    Interesting approach. According to my experiments it is all about the way you control the sm. I already had been involved in a project to silently drive a motor. Acoustic counter waves have been used...
