Airyware Tuner is a chromatic strobe tuner designed and optimized especially for windows phones. Powered by 64-bit NeatTimbreâ„¢ DSP engine it provides a robust pitch tracking through wide 9 octave tuning range from 15 Hz to 8000 Hz (~C0â€¦B8). The ability to reliably detect low frequencies (< 90 Hz) on smartphones allows precise tuning of such instruments as bass guitar or contrabass. Other interesting features include the reduction of background noise, support of external (headset) microphone and dual display of both stroboscopic and linear gauge as well as wave-stabilized oscilloscope view. Nice looking visual elements and smooth 30 frames per second animation provide a pleasant user experience.
Other features are common to other tuners and include the calibration of reference pitch, audition of target notes, user feedback and feature request forms, etc. This app is currently most expensive ($4.99) tuner available on the Marketplace, but it works excellent. Check it out yourself.
