Signal Lab app for iPhone and iPad

Generates sound from waveforms - Sine wave, Square wave, Triangle wave, and Sawtooths and visualize them in an oscilloscope. You can change waveforms and adjust frequency and amplitudes and see/hear the changes in real time.

Use it for:
- Generate tone for audio tuning
- Science class demonstration
- Visual demonstration of waveforms for a given frequency and amplitude
- Produce tone sample (up to 10 seconds)

Features:
- Intuitive slider control, with textfield for precise value entry
- Modes allow you to run the signal continuously or for a specific duration (up to 10 seconds)
- Export file (CAF format) of generated tone up to 10 seconds
- Large oscilloscope that beautifully displays the waveforms and respond to changes in real time
