Black Spectra

A real time spectrum analyzer with high graphical resolution adapted to music. BlackSpectra has been implemented to follow AES17-r2004 metering with a 31-band format to give an easy understanding as being human perceives sound. It provides a graphic control to the user to adapt the magnitude range. Also, it brings an attenuator to give reliable measurements at high sound pressure levels. Furthermore, it draws spectra captured by the Android microphone on logarithmic domain and linear domain, to give you the finest visualisation of frequency content. Ideal tool for sound engineers, professional musicians, music lovers and audiophiles. Time envelope has been added to smooth graphics and time parameters as attack, release and hold can be modified.
