A working toolkit — BPM and key detection, delay/reverb timing, harmonic mixing reference, and a few things worth bookmarking.
Upload a track and it actually analyzes the audio in your browser — real detection, not a guess. Nothing gets uploaded anywhere; it all runs locally.
Enter the song's BPM to get delay times for every common note division, plus suggested reverb pre-delay and decay.
