【iPhone神アプリ】Audio Analyzerの評価・評判、口コミ

Audio Analyzer is a real-time spectrum, spectrogram, oscilloscope and octave RTA analyzer. It gives you a visual representation of an acoustic signal. It can be used to analyze the sounds of musical instruments, to identify spoken words phonetically, to measure the frequency response of audio equipment, or to picture the calls of different animals. You can also check “The Singer’s Formant”, the most important measure for every opera singer.
