What is Generator? Description of Generator 2617 chars

A high-quality audio Signal Generator for the iPhone.

Now you can have a professional grade signal generator for your iPhone. Create sine waves, square waves, white noise, and pink noise.

Don't let the well-worn look of this classic audio must-have fool you, Generator is accurate, reliable, precise, and clean.

** NEW! Now supports remote control over WiFi from our AudioTools app. Connect an iOS device running Generator to your audio system, link to AudioTools on another device, and control Generator from AudioTools as you are free to move around. Requires that both devices be on the same LAN.

In sine and square wave mode, you can select between 20Hz and 20kHz using a controller that has three resolutions: octave, 1/3 octave, and fine. Frequency selection is controlled by smooth-gliding interlocking control wheels. Just spin to change frequency, by octaves, 1/3 octaves, or select fine mode to sweep through any value.

*** NEW: Tap the frequency screen to pop up a keyboard so that you can enter any exact frequency.

*** NEW: Tap the Wobble button to create a warble-tone signal for acoustics work. Doubles as an emergency siren!

When you are generating pink noise and white noise, you can select full band (20Hz-20kHz), or octave band limited noise for acoustical testing.

All waveforms are laboratory accurate, and use ANSI / IEC spec filters where appropriate.

The frequency sweeps smoothly, with no glitches. The mute is soft, to prevent loud impulses when mute or turning on a lower-frequency signal.

This signal can be sent to both channels (stereo), just the right or left channel, or the right channel output phase can be inverted for pseudo-balanced mode. This mode can be used with our iPhone Balanced Cable Adapter to get a balanced signal from your iPhone. See our web site for more information.

On an iPhone 3G, we have measured distortion at .006% THD at 1000Hz at full volume (+6.5dBu balanced). See our web site for more level details.

Note that digital square waves suffer from aliasing problems, and sound very strange above about 1500Hz.

Future versions will have options to select different skins.

Check out out other great professional-grade audio and acoustics apps: SPL, the iPhone professional-grade sound level meter, SPL Graph, for recording SPL over time, RTA, a 1/3 octave real time analyzer, FFT, for detailed audio analysis, ETC, the iPhone energy-time curve and decay app, RT60, for automated octave-band decay measurement, and Speaker Pop, the speaker polarity tester.

Generator Pros

✓ Pretty cool appI recomend it I use it to test speakers and bother other people with high pitched tones lol.RathatVersion: 0

✓ Well worth the money for casual useI 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..TnstatcVersion: 0

Generator Cons

✗ Phase?!?!There is no way to reverse phase!! Please please update. With that update this would be a 5 star app..UnhcampusVersion: 0

✗ Good but could be betterThis 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..MisterShaunVersion: 0
