Junk Amp
World of VibrationFIELD NOTES / app
Amplify taps, plucks, scrapes, and knocks. Watch the live waveform, compare input strength, and shape the sound with gain, drive, filter, space, and presets.

Plug the piezo into a microphone/headset input or USB audio adapter. Allow microphone access, pick the correct input, and raise sensitivity or gain slowly.
