Spectrograph app for iPhone and iPad

The Spectrograph displays and records real time spectrograms (visual representations of the spectral density over time) by processing the audio signal from the microphone input (or any external microphone connected to the input jack) or any digital audio input via the dock connector (if suitable external hardware is connected). It offers a 2D view and an amazing 360 degrees fullscreen 3D view.

Use the Spectrograph for studying music, animal sounds, voices and speech or just have fun with the beautiful visualization of environmental sounds! Make use of the ability to store and load spectrograms and even reprocess them with different settings for discovering new details in your recordings!
