Idea of the day
It is pretty easy these days to slow down or speed up sound without shifting the frequency — appropriate routines are easily available and there are even players out there which let you arbitrarily do that in real time. Now…
- Get a GPS unit and set up a script to request current motion speed.
- Record a BPM value for every song in your playlist.
- Figure out some value which determines what kind of song speed is appropriate for which car motion speed.
- Adjust the speed of the currently playing song to match, based on the song BPM and the current speed of the car given by GPS.
I’m gonna actually try something like this, it’ll be fun.
