Your Music Transcription Assistant. Visualize music and sound, almost as it might appear in a piano roll MIDI music editor. Picture the pitch frequencies of speech and singing. See musical notes (plus all their overtones) graphed to assist with music transcription. Find all those notes hidden inside harmonic content, or just rise and fall in pitch of all the sounds around you. The HotPaw Musical Piano Roll Spectrograph creates a scrolling pitch-centered 12th-octave spectrogram in real-time from mic input, or from iTunes music.

You can stop audio recording, and scroll back to review the past 4 minutes of spectrogram history.

Tap the gear/configuration icon to bring up several controls. The settings include 3 coloring modes: Black and White, Standard amplitude/Volume coloring, and the HotPaw magic inTuna pitch coloring mode (also used in the Sing-inTuna iOS app) that allows you to see if you are singing or playing in tune (green for close to in tune, blue for sharp, red for flat). There are also 3 filtering modes: full spectrum, only peak frequencies, and mostly lower frequencies. You can also adjust volume sensitivity and spectrograph contrast.

Tap the “Song” button to convert and visualize up to 4 minutes of music from songs from your iTunes library. Tap, scroll back and replay portions of interest.

Up to 7 octaves of frequency range (from 2 octaves below middle-C up to 5 octaves above) are viewable, or optionally zoom into 4.5 octaves (by turning the iPad, or in the configuration display on the iPhone). Music playback during spectrograph analysis is monophonic only. Not all iTunes file formats supported. PLEASE NOTE: For many musical sounds, you will see LOTS of overtones and harmonics, not just the fundamental note pitch frequency.
