Description

Signal Generator is an app that produces audio test tones. The basic app produces sine waves, and it can be extended and customized (via in-app purchases) to produce white noise, pink noise, frequency sweeps, and (on iPhone 4 and better) square waves, sawtooth waves, and triangle waves.

• Free Tone Generator. The app includes a free sine wave generator that generates signals from 20 Hz to 20 kHz, with a 48 kHz sample rate, 16-bit samples, and 96 dB of dynamic range. Frequency control via logarithmic knob or keyboard input.

• Pro Tone Generator. (Optional in-app purchase). Extends the frequency range down to 1 Hz, and adds stereo control and buttons to increment the frequency in steps. Anti-aliased square waves, sawtooth waves, and triangle waves are generated with aliasing kept to -54 dB or less.

• Noise Generator. (Optional in-app purchase). Produces white noise, pink noise, and brown noise. Pink noise falls off at 3 dB per octave (±1 dB). Brown noise falls off at 6 dB per octave. Option for stereo uncorrelated noise, or mono correlated noise.

• Frequency Sweeps. (Optional in-app purchase). Adjustable start and stop frequencies. Linear or logarithmic sine wave frequency sweeps. Single shot sweeps, repeating upward sweeps, and upward/downward sweeps.

This app can be used to:

• Test Speakers and Headphones
• Balance your Home Theater System
• Tune Your Car Audio System
• Mask Environmental Noise
• Burn In Headphones
• Tune Musical Instruments

Very Clear and User Friendly

I've been looking for a simple and user friendly signal generator app. Downloaded multiple apps and tested each one of them. This one is by far the most user friendly and very intuitive to use. Plus IMHO the interface looks very good indeed. Job well done!

Security Risk - Steals data

Be aware that this app steals what is on your clipboard when you open it, so potentially could compromise private information. Thanks to the new iOS update, when I open the app, I am told it has ‘pasted from’ my previous app. What is it doing with this harvested information stolen from users?

It does exactly what it says

Try it with an Apple TV or similar WiFI bluetooth to inject audio in any system. I bought all the options even though I did not need them - also adverts partly covered over the sone square triangle buttons.
