Your pocket
musician’s ear.
Record a song or drop any audio file. Understand the harmony that’s there, shape the sound you want it to be.
One recording.
Six layers of analysis.
Tonality Detection
Identifies the key and scale of any piece. Major, minor, modal, the harmonic center everything else revolves around.
Chord Recognition
A neural network trained on 301 chord classes. Major, minor, diminished, augmented, extended, altered, it catches them all.
BPM & Time Signature
BeatNet-powered tempo and beat tracking. Detects time signatures too: 4/4, 3/4, 6/8, odd meters.
Genre Classification
PANNs CNN14 identifies the genre landscape of your track. Not just one label, a weighted breakdown across styles.
Instrument Detection
Pinpoints which instruments are in the mix: piano, guitar, bass, drums, strings, synth, and more.
Song Recognition
Don’t know the track? Shazam-style recognition powered by AudD API finds the title, artist, and album.
Same chords, four different conversations.
Harmonic Analysis
Roman numeral analysis, tonal center mapping, color-coded chord functions. Diatonic vs. borrowed vs. secondary dominant, all visible at a glance.
Tonal center: C minor · Borrowed chord from A♭ major
Improvisation Map
For each chord, get scale suggestions and note choices for soloing. Pentatonic shortcuts, approach notes, avoid notes, practical improv advice.
Over G7 → G Mixolydian ♭9 ♭13
Target: E♭ on the Cm, B natural on the G7
Creative Alternatives
Tritone substitutions, modal interchange, chord extensions. AI suggests reharmonization ideas to transform the same progression into something new.
Cm → Cmmaj7 (add color)
Creates chromatic bass movement: C → D♭ → E♭
Plain Language
No jargon. This mode explains what’s happening in the music as if you’re hearing it for the first time. Built for beginners and curious listeners.
One tap, one printable lead sheet.
Any session becomes a formatted PDF: measure grid, chord notation, tonal center, AI insights, and reharmonized alternatives. Share with a bandmate or put it on the music stand.

A tool.
Not a ghostwriter.
SoundBud is a listening aid, not a generator. The musician, the engineer, the storyteller, is still you. We just hand you a better pair of ears.
AI hints, you create
Every suggestion, chord label, scale idea, reharmonization, is a prompt for your ear. The decision is always yours.
Your signature, your sound
SoundBud never writes, performs, or generates music for you. It listens, analyzes, and explains. The recording that leaves your phone is yours.
No AI residue in exports
No generative audio, no synthesized fills, no algorithmic voices, no watermarks. What you record is what you export.
Built for the curious,
not the certified.
