+#  How to extend Webpack config to load audio files
+
+Audio files should be processed by `file-loader`. This loader is already included in the default Webpack configuration, but it is not set up to handle audio files. You need to extend its default configuration in `nuxt.config.js`:
+
+```js
+export default {
+  build: {
+    extend(config, ctx) {
+      config.module.rules.push({
+        test: /\.(ogg|mp3|wav|mpe?g)$/i,
+        loader: 'file-loader',
+        options: {
+          name: '[path][name].[ext]',
+        },
+      })
+    },
+  }
+}
+```
+
+You can now import audio files like this `<audio :src="require('@/assets/water.mp3')" controls></audio>`.
+
+If you only want to write: `<audio src="@/assets/water.mp3" controls></audio>`, you need to tell `vue-loader` to automatically require your audio files when you reference them with the `src` attribute:
+
+```js
+export default {
+   build: {
+    loaders: {
+      vue: {
+        transformAssetUrls: {
+          audio: 'src',
+        },
+      },
+    },
+
+    extend(config, ctx) {
+      config.module.rules.push({
+        test: /\.(ogg|mp3|wav|mpe?g)$/i,
+        loader: 'file-loader',
+        options: {
+          name: '[path][name].[ext]',
+        },
+      })
+    },
+  },
+}
+```
