Every day we offer FREE licensed iOS apps and games you’d have to buy otherwise.
This giveaway offer has expired. Audio Spectrum is now available on the regular basis.
Audio Spectrum is a real-time FFT spectrum analyzer. It gives you a visual representation of an acoustic signal. It can be used to measure the frequency response of audio equipment or to analyze different sounds (e.g. sounds of musical instruments).
