Simply Record your tune into the app and it will graph the frequency / decibel level of the notes over time against your preferred Tuning system. There are also statistics available of decibel level over time as well as what notes have been played and their error in Cents.
You can now also view real time statistics of notes played on the main screen view the stats screen (swipe left) - RTTA (real time tuning analysis)
The speed of playback may be adjusted for a more careful analysis.
Tunes and graphs may be saved for later playback and analysis.
Audio files (mp3, wav, m4a, etc) can be imported for frequency and tuning analysis
Track wave files as well as track data (statistics and sampling points) may be shared from the Archive menu.
You can also pick from over a hundred different Tuning systems and even import your own Tuning System by editing TuningSystems.csv in the Apps data folder location.
