Aspect Pro is a spectrogram builder and analyzer.

Aspect Pro helps you analyze your local audio files by building their spectrogram.

The spectrogram will show differences in the frequency range when lossless encoding an audio signal and when lossy encoding.

For lossy encoded files (MP3, OGG),you can see the effect of the encoding bitrate on the presence of high frequencies in the audio signal.
