20Hz to 20kHz (Human Audio Spectrum)

Sinusoidal wave going trough entire human audio spectrum, starting at 20Hz and ending at 20kHz. Note that the frequency increases exponentially, the idea was to increase the frequency by constant fraction of currently played frequency rather than by a constant value (which would result in clearly noticeable fast change at lower frequencies and nearly no change at higher frequencies). Enjoy. Note: This wave has the same volume level measured by acoustic pressure all the time, however human sound perce
