Audio File Analyzer vs Audonia

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. Swipe left on a cell to copy its text. ================================================ [Note] This app can't add songs of the following formats. - Songs from Apple Music, iCloud, iTunes Match - Songs that are protected by digital copyright (DRM) ================================================

Ear-training exercises on intervals, chord qualities, cadences, and chord progressions. The cadences and progressions follow common-practice harmony and voice-leading, the style taught in university and conservatory theory courses: the leading tone rises to the tonic, sevenths resolve down, and parallel fifths and octaves are avoided. What you hear sounds like real music, not random notes. Practice the ear-training skills music schools teach and test, on your own, without a teacher at the piano. The exercises: • Intervals: Name the interval between two notes, ascending, descending, or harmonic. • Chord Qualities: Identify a chord's quality across voicings, played as a block or an arpeggio. • Cadences: Recognize Authentic, Plagal, Half, and Deceptive cadences. • Chord Progressions: Identify each chord in a functional progression, with optional inversions and the dominant seventh. Why Audonia: • Compare to hear the difference. After you answer, replay your pick against the correct one. • See what you heard. Every answer names what was played: the notes of an interval or chord, or the chords and their inversions in a cadence or progression. • Endless practice. Every exercise is generated fresh on your phone, so you never run out and never repeat a worksheet. • Works offline. Generation runs entirely on your device; no connection needed. • Light or dark mode. Follows your system preferences, or set it yourself in Settings. • Real piano. Sampled from an actual grand piano, not synthesized tones.
