Audio Analyzer

Audio Analyzer is a real-time spectrum, spectrogram, oscilloscope and octave RTA analyzer. It gives you a visual representation of an acoustic signal. *For 96kHz analysis use an external microphone with such capabilities through a USB camera adapter or through the iPhone/iPad dock connector (internal mic or external mic connected via the earphone jack can only be used for 44.1kHz or 48kHz analysis) You can also import files recorded on an external device.
