How to use audio Url in wavesurfer

[peterjones2023]

When I use the audio URL(https://samplelib.com/lib/preview/mp3/sample-3s.mp3), I will get a CORS error. So I converted url audio to buffer and used this code to use and it works but in V7 I don't know how to do that because some methods are removed.
code:
var audioContext = new AudioContext();
audioContext.decodeAudioData(buffer.buffer, function (audioBuffer) {
wavesurfer.loadDecodedBuffer(audioBuffer);
});

Thank you.

You can load a blob like this: https://wavesurfer-js.org/docs/classes/wavesurfer.default#loadBlob

do we have any example of this?

[katspaugh]

wavesurfer.loadBlob(new Blob([buffer]))

thanks if works :)

Just curious, how did you manage to fetch a buffer without CORS errors?

when I use the audio URL in Wavesurfer in JS it will throw a CORS error. So I used C# for converting audio into buffer.
