Tone Generator put to the test

I started with the free tone generator and realized that this app was awesome when it came to analyzing audio amplifiers. I used a Tektronix scope and found that this generator is cleaner and more accurate than the lab unit that I have at work. Since then, I have purchased all of the additional generators offered within the app, and let me just say that they all rival or exceed the pro commercial ones that my sound lab has purchased for equipment evaluations not to mention what each unit cost when originally purchased. This app is truly amazing. You will love using this app on all kinds of amplifiers, and speakers, as well as evaluating headsets.

Fabulously simple and functional

Love this app. The easy tog wheel for tones and sweeps is great. I do suggest and would love to see a bit more for pink noise generation. Correlated vs Uncorrelated for example and if it had 1/3 octave or possibly frequency limited pink noise generation it would be outstanding! Especially for Acoustics tuning in stereo domain with a DSP. I’ve also heard other pink noise generators or wav or flac files that seem to have more output at 0db so don’t know if the PN Generator is 0db at full tilt on the dial. So a suggestion to please consider.

Great app, very useful

I needed a waveform generator to help with frequency response testing, and this app does the job perfectly. After trying out the sine wave functionality, I purchased the rest of the features - I especially needed & like the noise generation (three types) and frequency sweep modes. For what this does, it beats using a bench top generator - on both price and portability. The additional features such as L/R channel select, semi-tone/cents/Hz increments, log/linear sweep, etc. make this even more useful.
