Bitcrusher: Breaking the Rules of Digital Sound
Bitcrusher History: From Mistake to Style. The bitcrusher was not always an "effect". Originally, it was a technological limitation. In the 80s, when the first video games used 8-bit audio, the low resolution of the sound was not an effect you applied whenever you wanted, but a consequence of the lack of processing power.
Prediction of vibration radiation noise from shell of straw …
In order to predict the radiation noise of the vibrating shell of the straw crusher in the design phase, the computational fluid dynamics–discrete element coupling method is initially used to simulate the airflow–straw coupled flow field in the straw crusher, and the pulsating pressure generated by the coupled flow field is applied to the inner surface of the shell of the …
