Voice grade spectrum analyzer full screen for android.
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.
You can adjust menu bar position.(dragging)
In some low performance device cause buffer over run.(speed may down),If so,Please stop background job,or try paid version without add.
No add version is available.
The application depends on terminal hard strongly.I tested on zenithink ZT-180 and worked fine.I hope it works on your device.
