The deCoda Black Friday deal puts zplane's song deconstruction tool at $38.86, 33% off, with the offer ending Nov 6, 2026.
You import an audio file and deCoda reports the key, the tempo and the chords. It also marks the song sections, such as verse and chorus.
It is a standalone application, not a VST, AU or AAX plugin. It runs next to your DAW rather than inside it.
Beyond the analysis, the maker built it as a practice and transcription tool. You can drop the tempo to hear fast passages more clearly, or shift the key to one that suits your voice or instrument.
The Focus EQ lets you highlight one instrument in the stereo mix. Inverted Focus removes that instrument so you can play along with the backing track.
The maker says the tempo and pitch changes run on zplane's elastique Pro time-stretching algorithm. deCoda also detects the tuning frequency of a song and matches it to your preferred tuning automatically.
Because deCoda knows the beat, tempo and structure, you navigate in parts, bars or beats instead of samples or seconds. A keyboard hit or a touch-screen swipe does it.
Sections loop automatically, and you can expand a loop just as quickly.
The chord, key, tempo and structure detection uses AI. The maker describes the results as educated guesses meant as a starting point for your edits.
deCoda reads wav, aiff, mp3, wma, flac and ogg files. It runs natively on Apple M1 processors.
On Mac it supports macOS 10.15 Catalina through macOS 12 Monterey, on Intel and Apple Silicon, 64-bit only. On Windows it supports Windows 10 and Windows 11, 64-bit only.
Both platforms need a 2 GHz CPU and a screen resolution of at least 1366 x 768.
zplane says its technology is built into many leading DAWs and is behind countless chart-topping records. deCoda runs on the same technology.
Yes. The deCoda Black Friday deal takes 33% off, bringing it to $38.86, and it ends Nov 6, 2026. deCoda is zplane's song deconstruction tool for finding key, tempo, chords and structure in any audio file you import.
No. The maker states that deCoda is a standalone application, not a VST, AU or AAX instrument. You run it on its own and bring results into your DAW by exporting MIDI or the slowed audio loop.
You can export the notes you trace on the piano roll as a MIDI file, or send them straight to notation software. You can also export the slowed version of a loop for any playback device, or a whole project as one shareable file.
It opens wav, aiff, mp3, wma, flac and ogg files. It runs on macOS 10.15 Catalina to macOS 12 Monterey, Intel or M1, and on Windows 10 and 11. All versions are 64-bit only and need a 2 GHz CPU.
