Project Info:
IntelliAmplifier allows a user wearing headphones to hear the sound around them at a much greater volume. This app can function as a hearing aid or simple audio amplifier.
It also incorporates an audio waveform display and a spectrum analyzer to show low vs. high frequency levels. The spectrum analyzer takes the audio input and runs it thru a Fast Fourier Transform (FFT) to graph the results in realtime.
IntelliAmplifier won the Wizard award in the 2014 Youth Apps Challenge.
