This app is designed to help musicians visualize sound wave generated by electronic synthesizers, acoustic instruments and any other sound sources. Features: - Supports both built-in microphone and direct line-in for capturing audio. - Supports "cycle locking". When plotting waveforms, the app actively tries to lock on to a particular point of the cycle. This results in a more stable plot instead of an unreliable blur. - Supports "free running mode". The free running mode can be enabled by the "Run" button. - Supports "freeze". By clicking the "Freeze" button you can freeze the current waveform. - Optimized for both phones and tablets.
