Abstract / Introduction
This is an android based mobile application that takes input of voice, sound from a nearby device and shows the spectrum of the audio. The sound is analyzed with Fast Fourier Transformation and the data is uniformly updated. The spectrum consists of the power in dB, shows frequency and wave form like sinusoidal. It takes less than one second to build the frequency response curve in the full audio range of 20-20000 Hz in 2.5 Hz resolution with the wideband audio signal generated by the same device. This app is useful to visualize your own voice or music or any other sound. It can also be used to test instruments or even tune them.
Development environments / IDEs for Android application Android SDK
