synpdf

synpdf is a javascript program that renders a PDF (or JPEG) score file and plays a media file (audio or video). It displays a cursor in the score that is synchronized with the playback

All software is javascript running in the browser. No server involved. No preprocessing required. You can select your own score- and media file.

Features:

• Reads pdf or jpg score files. Recognizes and synchronizes systems, staves and measure bars.
• Plays mp3 or ogg audio. Plays mp4 or webm video.
• Can load and synchronize video's directly from YouTube.
• Score and media can be opened/saved locally or from Dropbox.
• Can preload score, media and synchronization data.
• Can import the same timing data into different score parts (orchestre direction)

  https://gertim-alberda.com/chorales/BachChorales/B340.html Same example (BWV 12/7), but synchronized to a youtube video.(The choir sings half a note higher than the score).
  Same example (BWV 12/7), but with ABC score and real time synthesis of audio. Voice cursors are only visible on Soprano and Tenor (cursors on the other voices are disabled by a URL parameter).

Mixer Demos:

• synpdf.html?demos/011/011.js Lead sheet with audio mixer
• synpdf.html?demos/011/011.js&hrzleft Same exampole, but horzontal mixers left
• synpdf.html?demos/011/loop.js Same mixer sheet with clean loop.
  The mixer uses the Web Audio API which has very precise timing.
• synpdf.html?demos/011/vid.js Same mixer sheet with a video that shows the piano track running with audsync.
  You can see audsync with the piano track here, where it automatically computes the synchronization data that is used in this example for synpdf
