soundtouchjs + wavesurfer have delay or desync.

[tenkus47]

i have been trying to use soundtouch js with wavesurfer in prodigy app to fix the audio pitch problem when we change the playbackrate. the thing is that it works good and now the only problem is when i click play button and if i have set the playback rate to slower , the wave start moving first and after some minisec the audio start . that causes to end audio before its done playing and the next time i click on play the remaining sound shows up.

is there a way i can sync them together.i have seen many post related to this issue but didnt really got a good answer.

• somehow if we can slowdown the speed of wave without affecting the audio rate but it doesnt seems to be a good solution.

this link gives a example of using wavesurfer with soundtouch but this shows the exact problem i am facing ,example . they tried a sound that have empty sound on starting and end ,so it looks fine but my audio file directly start and end with actual sound so it is a big problem.

If your goal is just to change the speed (or speed and pitch) of the audio, you don't need soundtouch, just set the desired playback rate.
See this example: https://wavesurfer-js.org/examples/#speed.js
