### LOAD FILES

keyboard = VideoFileClip("./P1030015.MOV", audio=False)

# 2 microphones: computer audio output, and ambient noise 
audio_ambient = AudioFileClip("./SR018MS.WAV")
audio_music = AudioFileClip("./SR018XY.WAV")

SIZE = W,H = keyboard.size

### ASSEMBLE AUDIO

a_start, a_end = 14.5, (2,0)

audios = audio_ambient_p, audio_music_p = [
    c.subclip(a_start, a_end)
     .audio_fadein(.2)
     .audio_fadeout(.2)
    for c in audio_ambient, audio_music]

audio = CompositeAudioClip(audios)

### MY PERFORMANCE

keyboard_p = (keyboard.subclip(11.6)
              .set_audio(audio)
