We like the idea of abstract waves, possibly mixed with elements of "the matrix" type digital 0101 to portray our engineering and creative expertise. No busy layers or complex background though, as we need it to be clear and transparent, but these elements can be combined into the same graphic. Perhaps the idea of sound passing through a wall/object that decreases in amplitude after it passes through would work, or maybe just one primary flowing wave. Then again, maybe you have an idea that would work even better.
Use your imagination, as far as color, we prefer hues of blue. No orange or green.
We'd like a transparent background so as to integrate in letterheads etc.
No audio waveforms from audio editing program- too cliche
no speakers, subwoofers, electronics, headphones, equalizers, or shrubberies.
