They can put a man on the moon but you still need to tune your guitar one string at a time. What’s with that?  What is this, the middle-ages?

Polyphonic tuning, or sounding each string simultaneously so you can easily identify if a particular string – or strings – is out of tune would make life much easier than having to check each, one at a time.

It’s not that easy though.  Isolating each string amongst the harmonic overtones of the others isn’t easy to do.  Until now… Possibly.

This Danish software engineer (with the YouTube name DspInventor) demonstrates a prototype system to allow polyphonic tuning.  It’s all early days but it’s an impressive demo and it’s easy to imagine this sort of functionality being shoved into a rack or pedal unit to allow easy, stage tuning.

Lets hope it happens quickly.  All credit to GuitarNoize, where I read the story first.
