Spectrum analyzer (com.cyberlabo.android.mpaper) on Google Play
It is a Spectrum analyzer of the voice grade. The sound picked up from the mic of the terminal is analyzed with the frequency.It has a basic function though it is a simple type. I hope it works on your device.The performance depends for the terminal hard and strongly.I tested on zenithink ZT-180 and worked fine.Touch parameter then can change.If menu is out of display,please flip it.
