Are you an audio amateur, hobbyist or professional? Do you try to avoid clipping in your recordings? To help you get your audio levels right in the January 2012 issue Elektor published a professional quality peak level meter featuring 2x 40 LEDs, controlled by a powerful digital signal processor (DSP). Being part of the 8-lesson course on Audio DSP all the theory behind the meter was explained, and the accompanying source code made available as a free download.
The DSP board has been available for a while, and now we are proud to announce that the Digital Peak Level Meter is available as an Elektor quality kit for you to build. Although the meter was designed as an extension module for the Audio DSP board, it can be used with any microcontroller capable of providing SPI compatible signals.
