Audio Spectrum Viewer

Audio Spectrum Viewer is an easy to use app which will show the frequency content of your live audio environment in an easy to understand waterfall / spectrogram. This tool can be used to analyze the performance of speakers and sound systems, and to create audio fingerprint images of environmental sounds such as bird songs and other animal sounds. Audio Spectrum Viewer is a powerful tool with user-selectable gain, sample rate and other parameters to optimize for a particular setting. Spectrograms can be saved to the camera roll with a timestamped and customizable caption and the audio clips can be saved for later playback. Audio can be captured in the background so you can simultaneously take photos of birds while analyzing their sounds.
