Pitch shifter - HTML5 Video audio FX插件简介

Pitch shifter - HTML5 Video audio FX插件描述

# Now fixed!! #

Pitch shifts audio from HTML5 Video sources on a page, without changing the playback rate (unless you want it to).

Potential use s:

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 (wont needlessly slow your computer down).

Troubleshooting


If you get no audio from the video it may be that the video is an ad from a different site  the CORS policy prevents us from altering the sound. Were looking at ways of detecting this.



v1.5 8 Feb 2017
 Fixed bug no pitchshifting 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).

Change log:
v1.4 15 Feb 2016
 Range of semitones is 24/+24, which gives the same range as the "smooth" option,  is the same range as v1.2

v1.3 12 Feb 2016
 Fix issue with pitch shifting in tones not semitones. Thanks f the bug rept guys!

v1.2 27 Oct 2015
 Pitch shift by semitones, experimental feature. Change mode using select box  classic smooth  new semitones.
 Fix bug where playback rate was not persisted when a video changed.
