Music Spectrum: Simple Audio Visualizer

Music Spectrum is a very simple music player that lets you see your music while you listen to it, with a live view of its spectrum (frequencies) and its waveform.

Unlike other music visualisers and players, this app puts its focus on the accuracy of the audio content itself - making sure what you see will closely match what you hear in every millisecond.

Features:
- Visualisation of sound from the microphone or from songs in the local iPod library only
- Spectrum (zoomable) , waveform, VU meter and bass-responsive particle system

It also supports iOS 5.1.1 and up.
