Pitch shift the audio in HTML5 videos on any webpage, e.g., YouTube
# Now fixed!! #
Pitch shifts audio from HTML5 Video sources on a page, without changing the playback rate (unless you want it to).
Potential use cases:
Fixing the voice of a too whiney youtuber.
A satanic version favourite movie clip.
Or a chipmunk remix of a legendary rap song.
Does NOT save any of your data to a remote server.
Does NOT load the pitch shifter on webpage until you enable it (won't needlessly slow your computer down).
If you get no audio from the video it may be that the video is an ad from a different site and the CORS policy prevents us from altering the sound. We're looking at ways of detecting this.
v1.5 8 Feb 2017
- Fixed bug no pitch-shifting bug on Chrome 56. Seems there was an API change/fix so thath AudioParam.setTargetAtTime(target, startTime, timeConstant) required startTime to use the currentTime from the Audio Context, not a relative time (we were using 0).
v1.4 15 Feb 2016
- Range of semitones is -24/+24, which gives the same range as the "smooth" option, and is the same range as v1.2
v1.3 12 Feb 2016
- Fix issue with pitch shifting in tones not semitones. Thanks for the bug report guys!
v1.2 27 Oct 2015
- Pitch shift by semi-tones, experimental feature. Change mode using select box between classic smooth and new semi-tones.
- Fix bug where playback rate was not persisted when a video changed.
