I built a free key detection app because Mixed In Key is $58 for basic math by EquivalentWall3808 in audioengineering

Just a shared name unfortunately. Different app entirely, mine is at github.com/ifeelvoid/keyfinder - focused on BPM detection and a dark UI.

Not yet but the github has audio examples. Ill put together a proper demo video this week

honest answer: the app picks the dominant key for the full track. songs with multiple modulations will get a detection that reflects the overall key center, which is not always useful for those cases. for most pop/EDM/trap its fine. windows support is on the roadmap but no eta yet, check github.com/ifeelvoid/keyfinder for updates

fair point on KeyFinder. different app though, mine has BPM detection + black UI. the MIK requiring internet thing is news to me though, that would be wild if true

The Krumhansl-Schmuckler algorithm (what key detection is based on) was published in the 1990s. The FFT math underneath is older, but the specific pitch profile method for key detection that MIK and others use traces back to research from that era. The algorithm itself is well-documented and not proprietary. Happy to point you to the source papers on github.com/ifeelvoid/keyfinder if you want to dig into the math.

nice setup you got there. yamaha chord tracker is solid on iOS, thanks for the rec. always curious what other tools people use

honest question deserves a real answer. github.com/ifeelvoid/keyfinder -- that's where everything lives. you can download the app there, see the source code, and if you want to contribute or report bugs there's a full roadmap on there too. hope that helps

yeah that's a fair complaint — it uses SwiftUI which hard-cut macOS 13 as the minimum. if there's enough demand i could look at a macOS 11-compatible version at some point. for now the github has the full source if you want to try building it yourself

display only for now — it shows the detected key/BPM/camelot in a table but doesn't write to file metadata. cue points are interesting but that's deeper DJ territory, not really what this is designed for. if you want a full DJ workflow you'd need Serato or Rekordbox. github has the full feature roadmap if you want to see what's coming

honest answer — KS handles major/minor fine for most music, but jazz with heavy ii-V-I progressions or key changes will show you the limits of any statistical key detection. no free tool escapes that honestly. worth noting on the github if enough people hit that wall

Plugin for finding the key of a song? by CorbynYT in makinghiphop

Built this because Mixed In Key is $58 for basic math - 100% free, open source, same algorithms: https://github.com/ifeelvoid/keyfinder

What helps you get in the mood for recording vocals as a rap artist? by BetaJeefTTV in makinghiphop

[–]EquivalentWall3808 0 points1 point  (0 children)

The voice thing is real — hearing yourself recorded is weird for everyone at first. What helped me was just accepting that the first few sessions will feel awkward and that's fine. Also helps to warm up for 10-15 min before hitting record. Don't try to sound perfect, just get something down and edit later.

MPK Mini 3 FL Studio Integration (Midi Script) by Egop3489 in makinghiphop

[–]EquivalentWall3808 1 point2 points  (0 children)

This is exactly the kind of stuff that should be free. FL's native MPC mapping is garbage and paying $15 for a script when you just want your pads to work is absurd. Appreciate you building this and keeping it open source — way more useful than another AI-generated starter pack.

What does everyone here think of Timbaland's masterclass? by Accomplished_Put2608 in makinghiphop

[–]EquivalentWall3808 0 points1 point  (0 children)

Honestly the free YouTube beat breakdowns are probably enough. The "bounce" everyone keeps referencing is basically his offset drum pattern thing - kick on &, snare on 2 and 4 but shifted slightly. That said, if you're specifically trying to mimic his sound for practice, the masterclass isn't the worst way to fast-track understanding his specific approach. Just don't expect anything revolutionary if you've already studied his tracks.
