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)

• synpdf.html?demos/beet26.js Sonata 26, demonstrates bar line recognition in bad quality pdf.
• synpdf.html?demos/bwv99.js Chorale BWV 12/7, with audio (mp3) and score (pdf) (subtle tempo changes and breath pauses as with a real choir). Manually synchronized with synpdf.
  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&mute=2&tvol=60,0,60,40,40&tpan=100,0,100,0 Same example, but presetting volumes, panning and mute with URL parameters
• synpdf.html?demos/011/011.js&hrzleft Same example, 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
