[linux-audio-user] programm for tuning

[kern at kontaktkode.ch]

Hi folks

Is there already an application that makes piano tuning easier? That 
would be done by:
-analysing the waveform coming in through the mic
-comparing with an ideal one (ideally depending on choosen 
temperature - that's why a laptop (besides the cost) would be optimal for 
this task)
-giving a gui-sign to adjust to this (as the LEDs of an analog tuner).

Are there other problems to encounter I forgot now?

Thank you for your suggestions.

David
