Decibelion 소개
You play ... we display!
Say good-bye to guess-work at what note you're playing on your instrument and whether or not that fingering is in-tune or not. The Decibelion app is a special musical instrument tuner app that uses the device's microphone to show you the note on the music staff that it detects, and it shows you if you're in-tune or out of tune!
On the "music mic" screen, a green fully-filled-in note means you're in-tune. A red note with only its bottom-half filled in means you're out-of-tune flat. A blue note with only its top-half filled in means you're out-of-tune sharp.
The music staff supports switching between the treble, bass, alto, and tenor clefs, and it supports displaying the note an octave higher or lower (8va notation). The key signature can be cycled through all the major and minor key signatures that are available in music theory without resorting to double sharps or flats.
The triangles above and below the music staff allow for cycling through these options, and clicking on the key signature toggles between the major/minor key.
In addition to the music staff which in portrait orientation bends down and connects to the keyboard at the bottom of the screen, the music mic also indicates the scientific note name (G3, F#4, A5, etc.). The keyboard at the bottom displays the piano key to which this note maps. The middle C and the A-440 piano keys are marked with a small circle dot for reference.
There are no ads; who likes ads, anyway? But the "music mic" screen does have a 30 minutes per day "daily demo" time limit which can be unlocked for unlimited daily use by making a one-time in-app purchase.
The Decibelion app also has a regular "tuner" screen that can be used as a violin or guitar tuner. The tuner screen shows the detected pitch (in Hz), the scientific note name, and a tuner dial of how many cents sharp or flat.
Finally, there is a "math mic" screen that shows the mathematical spectrum plots of the microphone audio. This screen can be used by audio engineers or by students or teachers who are learning about audio spectra and harmonics in music.
So, whether you'd like to see mathematical plots of sounds, or you're looking for a new guitar tuner, or you're learning to play a musical instrument, Decibelion might be an option for you!
And if you end up not liking it, that's okay too - the app is free to use for up to the daily demo time limit, and you can try it for as many days as you'd like. If there's something wrong with it, please use the in-app link to the user feedback form to let me know. The feedback form is anonymous. And if you never pay for the app but the 30 minutes per day still helps you learn, great!
Either way, I hope you enjoy the app, and thank you for your time and consideration!
