The console outputs 48000 and only shows the spectrogram up to 24kHz. If it actually was a 48kHz file, stopping at 24kHz would make sense. It seems to use that range of 0-24kHz for every file and there doesn't seem to be any way to either change the spectrogram sample rate or make WaveSurfer treat. wavesurfer-spectrogram-with-frequency-labels">Example reference on github.com. 4. . 5. ​. 6. div id="waveform">. 7. ​. 8. . 9. ​. 10. button onclick="wavesurfer.playPause()">. 11.
