Oscillator

This app has been a great resource for me to calibrate some of our equipment. The only thing I would request is that field for the volume be editable as well so thats it is easy to set some known values. Otherwise thanks heaps!

Not professional, but very practical. The square wave isn't perfect but the description did say that. I was pleased to see that you can change the minimum and maximum frequency points. An update with pink noise instead of white noise would be much appreciated.

Very handy and economical sig gen. Incredible for the price.

This is better than the $95 signal generator I bought from Jaycar Electronics! Just the thing for checking out loudspeaker resonances and adjusting graphic equalisers for room acoustics.

Works well and it will makes life easier for checking sound systems and lines on a multicore for live sound guys or studio! It's preset for the first time use as 100Hz - 3Khz but it can be set to 20Hz - 20Khz so don't panic!

Please please PLEASE - give us the ability to jump around the frequency by tapping along the fader!? This is a new instrument waiting to happen! An addition of a resonance and cut off fafer would escalate this app into a must have for most music making people. (me thinks)

Very handy little app that I have used in my music tech lessons. Although like its been said before, 20Hz - 20kHz or something very close would make it a 5+ app at this price!

This is great. It does what it says on the label. The only issues I have are 1. it turns off whenever my iPhone goes to sleep. Please can you fix this? Maybe have an option to disable sleep whilst in use? 2. the oscillator only goes from 100Hz to 3kHz. It would be great if it could go lower and higher. 20Hz to 16kHz maybe. The first is a huge issue as I leave it on and walk away. Very nice app. Recommend it to anyone who uses powered speakers or DSP-laden amps like the LA8 from L-Acoustics

This is great , so useful for testing systems.

There's not much to this app but that's what I like about it. It's very slightly glitchy occasionally, just if you move sliders too fast or maybe when using multi touch on a couple of sliders at once, but who cares? Lots of the best music is rough and glitchy. Sounds great with a bassy EQ, rough overdrive (on the sine wave, mmmm), delay and reverb. Thereminesque when moving the frequency slider. If I'd made this, one minor (and hardly necessary) improvement I would make would be to add an option to snap the frequencies to those of the notes of the piano (and octaves lower), so you'd get a similar effect when moving the frequency slider but then when letting go it go, the slider would move to the nearest value, eg. from 445 to 440. The button to toggle this on and off could fit if the play key was made smaller, not adding any clutter! Anyway, buy this, even if its just to be a bad person and sit in class/at work/in a cafe driving people mad with irritating, barely hearable, high notes!
