## Questions
Have a question about integrating wavesurfer.js on your website? Feel free to ask in our [Discussions forum](https://github.com/wavesurfer-js/wavesurfer.js/discussions/categories/q-a).
However, please keep in mind that this forum is dedicated to wavesurfer-specific questions. If you're new to JavaScript and need help with the general basics like importing NPM modules, please consider asking ChatGPT or StackOverflow first.
### FAQ
<details>
<summary>Does wavesurfer support large files?</summary>
Since wavesurfer decodes audio entirely in the browser using Web Audio, large clips may fail to decode due to memory constraints. We recommend using pre-decoded peaks for large files (see <a href="https://wavesurfer.xyz/examples/?predecoded.js">this example</a>). You can use a tool like <a href="https://github.com/bbc/audiowaveform">bbc/audiowaveform</a> to generate peaks.
</details>
<details>
<summary>What about streaming audio?</summary>
Streaming audio is supported only with <a href="https://wavesurfer.xyz/examples/?predecoded.js">pre-decoded peaks and duration</a>.
</details>
<details>
<summary>There is a mismatch between my audio and the waveform. How do I fix it?</summary>
If you're using a VBR (variable bit rate) audio file, there might be a mismatch between the audio and the waveform. This can be fixed by converting your file to CBR (constant bit rate).
<p>Alternatively, you can use the <a href="https://wavesurfer.xyz/examples/?webaudio-shim.js">Web Audio shim</a> which is more accurate.</p>
