Simple tone generator APK 1.20

5 stars: excellent tone generator, very useful for setting up sound system/stereo. sub generator useful for finding best sub position in room. can also use it to find room nodes and to position tube traps/diffusors/damping panels. Could also be helpful in setting crossover frequencies between main speakers and sub.
4 stars: VERY useful for the diy electronics people, like myself. A handy tool to have, and I recommend it to anyone who is into electronics, especially if dealing with alot of audio equipment.
5 stars: All frequency test tones very Nice. Only thing it doesn't show is db volume on screen. Plug headphone on set any tone turn volume up until you hear it change to a distort sound then turn down until you get the right tone. Some devices may vary I assume as a volume level output range control.
4 stars: It does exactly what it says, generate any range of audio tones. You can use it for tuning any instrument or for figuring out the frequency of any sound, from industry to nature. Also handy to teach novices about sound and frequencies.
5 stars: It is just what i deeded to test 1 sub, four doors with 6.5\
5 stars: It works, I just wish that if you touched and held the frequency +/- buttons that it would go up and down continuously instead of 1 hertz at a time. The slider is too coarse.
4 stars: Tones appear to be accurate but I have no way to test them. I am trying to match the tones of my tinnitus but with this type of control it is very difficul
