Controlling Pitch

Use the toneFrequency prop to control the pitch of audio during server-side rendering. It is supported by <Audio>, <Video>, <Html5Audio>, <Html5Video>, and <OffthreadVideo>.

toneFrequency is not supported during preview or client-side rendering.

Values between 0.01 and 2 are accepted, where 1 represents the original pitch. Values less than 1 will decrease the pitch, while values greater than 1 will increase it.

A toneFrequency of 0.5 would lower the pitch by half, and a toneFrequency of 1.5 would increase the pitch by 50%.

    <AbsoluteFill>
      <div>Hello World!</div>
      <Html5Audio src={staticFile('audio.mp3')} toneFrequency={0.8} />
    </AbsoluteFill>
  );
