Audio File Analyzer

(This app is developed in Japan. If it's displayed in "Japanese", please add "English" to "PREFERRED LANGUAGES" in [Settings]-[General]-[Language and Region].)

This app supports simultaneous display of the "audio waveform" and the FFT-based "amplitude spectrum" (frequency magnitude) for audio files on your device. (FFT: Fast Fourier Transform) You can check the frequency components around the current playback position while playing the file.

[Features]

• Simultaneous display of audio waveform and a real-time spectrum linked to the playback position
• Supports both portrait and landscape orientation
• Channel display switching (Mix / L / R)
• Displays the peak level of the spectrum and its frequency
• Supports zooming in the frequency direction of the spectrum

[Spectrum Display Settings]
