This app displays the "Audio Waveform" together with the FFT-based "Amplitude Spectrum" (frequency magnitude) or the "Spectrogram" (changes in frequency components over time) 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] - Add audio files from "Files" or songs from "Music" to a playlist within this app. - Simultaneous display of audio waveform and a spectrum / spectrogram 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 / spectrogram. - Pitch meter display. - Supports transcription in a specified language. (iOS 26 ~) The Pro version offers Ad-Free Viewing and High-Resolution Analysis (FFT size: 16384). [Spectrum / Spectrogram 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 - (Spectrum) Octave Analysis: FFT, 1/24, 1/12, 1/6, 1/3, 1, Calc Method: Max, Ave - (Spectrogram) Display Duration: 5–30 seconds, Display Range: -60 to -150 dB [Transcription screen] (* Available on iOS 26 or later.) Transcribes speech in the selected audio file. The results are divided into recognized speech segments and displayed in cells with their start times. Tap a cell to move to that position.

Verdict
The clearest difference is ads: Audio Spectrum Analyzer dB RTA at none against Audio File Analyzer's shown. Audio Spectrum Analyzer dB RTA also leads on ratings volume (3K vs 2) and iOS requirement (15 vs 18.0). Audio File Analyzer's advantage is update cadence (every 10 days vs every 5 months). On price, rating, in-app purchases and monetization model there is nothing between them.
