Acoustiwall, at its most basic level, is a graphical audio spectrum analyzer and equalizer. It shall be implemented as a wall fixture, which one might also employ as a decorative piece within a residence, studio, etc.
Both the spectrum analysis and artistic appeal of this product will be exemplified by the six 16x32 LED arrays that constitute the centerpiece of the project. Each column of the LED arrays will be controlled by its corresponding frequency band, which will be analyzed in real time by the microcontroller. Each band will feature an adjustable output as well, implemented with a passive filter network and potentiometers to the control the feedback to an op-amp. In this sense, the unit will also function as an equalizer and feature a corresponding preamp output.
