Low THD
There are better generic sine wave generators. Use this one if you are trying to measure distortion. Out of the generators I have tried, this is the only one with a THD spec mentioned. In practice, it is a much cleaner source than my other software generators. I assume this is because the designer took the time to add filtering to the output. For audio measurements this crucial.Show lessjtnorthwest
Awful interface
I never write reviews, so I’ll make this short. Save your money. Remember all sales are final and you get no refunds for trying stuff out. I gave it two stars because well, it makes noise once you disengage the mute button. The interface is cumbersome and very 1980’s. Very few options, and there’s better options out there. Sorry.Show lesshonestly_thisiswhatithink
Fine control is frequency sweep
Please bring back the fine control of the frequency select dial. The rotor dial when in portrait mode helped select very fine specific frequency of sign tone.fastfader
extremely useful sound tech app
I plug a handset into my phone when I'm mixing a show. If I hear a frequency I don't like, or something that's about to feedback, I fire up Generator and match the pitch. This tells me precisely what frequency needs to be notched. With this update, it once again runs fine on my 3GS (iOS 6.13) and my iPad Touch 4 (iOS 6.15). Great use for obsolete devices.Show lessnottooloud
ios5 killed it
this used to be a near perfect app but does not work under ios5 and even locks the sound device so other apps and music cannot be played until a reboot has been performed please update this app as its one of my favouritesPsychic 17
tone generator
VERY low output. Just about unusable for the purposes that I had originally purchased it for. Can folks return apps when they just do not function as they they were advertised to be?soundguy1000
Well worth the money for casual use
I needed a signal generator for my daughter's science fair project, and this fit the bill perfectly. We were building a Rubens' Tube, and needed to generate tones at various frequencies to produce standing waves in the tube. I cannot speak for this app's accuracy as I didn't check, but it was very wasy to twiddle the dials to find the right frequencies, and then to enter them again directly from the keyboard when we were re-doing things for the video. The only complaint I might lodge would be that while in "fine" mode, if you're not looking at the screen, it's a little too easy for your finger to wander off the dial you're moving and make changes to other dials/switches, resulting in some unexpected behavior. I don't know what they could do about this without tactile feedback, but it's something to be aware of.Show lesstnstatc
Good but could be better
This frequency generator works well, for tones (sine and square) but white/pink noise seems tinny. At lower frequencies white noise should be full audio spectrum and it doesn't seem to be. It could do with L/R/Stereo channel switching buttons on main page. No info on how to change the modulator sweep speed and depth etc. if that's possible. Very easy to set frequency and very accurate. I love the rotary frequency sweep dial. A good audio test tool, at a cheap price, and with precise calibration.Show lessMisterShaun
Phase?!?!
There is no way to reverse phase!! Please please update. With that update this would be a 5 star app.Unhcampus

Nice tool, but lacks a sine sweep option. Maybe they can work that into an update.Pro Audio Guy
