Harmonize

HARMONIZE

1. Elevator Pitch

• Create audio recordings through IOS device or browser
• Choose desired recording and create a complementing harmony
• Can be used as digital instrument

2. Developer Notes

• Compatible with web only
• Uses expo-av to take recordings/play on the RecordingPage
• Uses Web Audio API in order to process and play harmonized audio from the CreateHarm page
• Pitch of layered tracks are increased by manipulation of cent value
  • 100 cents = 1 semitone/half step, 200 cents = 1 whole tone/whole step
  • Space Harmony: various stems overlayed with slight latency to create spacey sound
  • Delayed Harmony: original recording stem increased on layering stems such that a third, fifth, and the seventh of the original recording is added

3. Limitations

• Currently supports recording in browser
• Records audio on IOS device
  • file path of sound can be found but not accessed at the moment
• Does not change the pitch without changing the tempo
  • Web Audio API does not allow direct Granular synthesis of recording stems
