频谱分析 IHASpectrogram & IHASpatialAnalyzer v1.1.0 PC版

What is a spectrogram? A spectrogram is a tool developed to analyze the frequency content of an audio signal. It shows you the strength of a frequency over the time. The strength itself is coded in colours. What is it good for? The application areas are manifold. Sound engineers and audio researcher use a spectrogram to find the pitch frequency of an instrument, to find annoying single tones, to show the effect of different dither and noise-shaping algorithms, or just to see, if a mix is well balanced in its frequency behaviour.
