A new version of Audio Tuner has been released.
This version adds tunings for the Mandolin, and the Autoharp. Also, the user interface has been simplified. The incoming signal from the microphone is no longer displayed by default, as it is only useful for troubleshooting.
Any problems or requests, please let me know. If you play an instrument that isn’t listed, feel free to send me the details so I can add it to the tuner.
