Piano Opus

A collection of some of my piano performances.

MP3 Files:

Recorded with Yamaha P125 and either Guvcview or Audacity. When Guvcview was used, I converted to mp3 with ffmpeg.

Metadata:

• Stream #0:0: Audio: mp3 (libmp3lame), 44100 Hz, stereo, fltp
• encoder : Lavc58.54.100 libmp3lame

Piano roll videos:

Recorded with Yamaha P125 Piano.

Rosegarden records MIDI; Guvcview records audio.

MIDI files are run through MIDIVisualizer to create visualization

Then audio and video, which are seperate at this point because MIDIVisualizer has no sound, are passed through ffmpeg which:

• Re-encodes both audio and video

• adds both audio and video to the same file

• exports into webm format, which is highly compressed

i.e.:

ffmpeg -i "Sunshine of Your Love.wav" -i "Sunshine of Your Love.mp4" "Sunshine of Your Love (w audio).webm"
