# resampleTo16Khz()<AvailableFrom v="4.0.518" />

Decodes an audio `Blob`, mixes it to mono, and resamples it to the 16kHz waveform expected by [`transcribe()`](/docs/whisper-webgpu/transcribe).

```ts twoslash title="resample.ts"
import {resampleTo16Khz} from '@remotion/whisper-webgpu';

const file = new File([], 'audio.wav');
const waveform = await resampleTo16Khz({
  file,
  onProgress: (progress) => console.log(progress),
});

console.log(waveform);
```

## Options
