Audio Signal Generator

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.

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.

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.

My need is to be able to find pitches that are feeding back in live stage monitors. For that purpose this is a great tool! Since that's all I need, I'll probably be using this for a long time. It gives you the precise frequency that you're listening to numerically which works great with the modern digital mixing consoles. I can basically tell the engineer exactly what frequency to go to cut using this tool.

Outputs a clean sine wave with practically infinitely variable frequency from 20 Hz to 20 KHz. Easy to use and hit specific frequencies since the dial is split into 5 sections. I used this today to find a rattle in my car. I have a small sub and was getting a rattle at certain frequencies. I was able to find the frequency within a minute, and subsequently the rattle as well.
