HotPaw Musical Piano Roll Spectrograph - Your Music Transcription Assistant
Visualize music and sound as it might appear in a piano-roll MIDI music editor. See the musical pitch of music, singing, and speech. Musical notes (plus all their overtones) can be graphed from songs in your music collection, or in real-time to assist in your understanding of live music. The HotPaw Musical Piano Roll Spectrograph can create a real-time scrolling 12th-octave pitch-centered spectrogram, either from microphone input, or from your iTunes music collection. You can stop audio recording, and scroll back to review the past 4 minutes of spectrogram history. You can even hear the major ssound frequencies in your music, not in slow motion, but actually stopped in time.
You can stop recording and scroll back to review the MIDI sound history. The ReSynth button will replay the MIDI tones contained at the current audio cursor location, stripped of percussion, consonants and most other attack transients, so you can just hear the pure musical pitch, chords and/or harmony at that point in time (with most of the stronger overtones included). Scroll back-and-forth to hear the MIDI tones at other points-in-time. Scroll forward slowly to hear a strange robotic vocoder-like resynthesis of the sound or music. Touch the on-screen keyboard in ReSynth mode to hear just the nearest frequency note in the music.
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. 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).
New: The Volume or Black and White display modes will show higher resolution spectrograms when Paused.
Tap the "Song" button to convert up to 4 minutes songs from your iTunes library for MIDI visualization. Tap the "Song" button again to switch back to microphone input.
Music playback during spectrograph analysis is monophonic only. Not all iTunes file formats supported. DRM protected iTunes files are not supported.
Warning: For most musical sounds, you will see LOTS of overtones and harmonics, not just the fundamental note pitch frequencies.
New in version 1.3.0:
The spectrogram is now displayed with 4X higher resolution when paused in the Volume and B&W coloring modes.
Keyboard synthesis was added to the ReSynth mode to isolate hearing 1 pitch in the MIDI spectrum.
The ability to paste audio into song player was added.
Also: Fixed some issues with the Volume setting, the AGC, and Song selection.
