## Description

(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.
- Pitch meter display.
- Supports transcription (iOS 26 ~).

The Pro version offers Ad-Free Viewing and High-Resolution Analysis (FFT size: 16384).

[Spectrum Display Settings]
- Frequency Axis: Linear, Log
- FFT Size: 1024, 2048, 4096, 8192, 16384 (* 16384 is available in the Pro version)
- Window Function: Hann, Hamm, Blkman, None
- Octave Analysis: FFT, 1/12, 1/6, 1/3, 1, Calc Method: Max, Ave

[Transcription screen] (* Available on iOS 26 or later.)
