Android App "Absolute FFT" can execute frequency analysis wherever you want. Analyze every sound around your daily life. Now you are a person with Absolute Sense of Notes! ★FFT Analysis App for Android FFT; Fast Fourier Transform is a method to identify frequencies in any sounds or vibrations. FFT is used for vibration or noise analysis in engineering fields. In this post, I'll introduce Android App "Absolute FFT", which identify frequencies in sound files. ★★★ Download at Google Play ★★★ ★Find Frequencies in Sounds It's easy to use the App. Touch "Open" and select the audio file you have. After that, the wave form and FFT result will be shown in the screen. This example shows the result of analyzing a sound file, which contains 300, 400 and 600 Hz waves. This App's special feature is that the results can be shown in not only frequency, but also in "notes names (do-re-mi)". The graph below is the sound of harmonica, which shows
