# AVAudioTimePitchAlgorithm

An algorithm used to set the audio pitch as the rate changes.

```
struct AVAudioTimePitchAlgorithm
```

## Topics

### Type properties

[`lowQualityZeroLatency`](/documentation/AVFoundation/AVAudioTimePitchAlgorithm/lowQualityZeroLatency)

A low-quality and very low computationally intensive pitch algorithm.

[`spectral`](/documentation/AVFoundation/AVAudioTimePitchAlgorithm/spectral)

A highest-quality time pitch algorithm that’s suitable for music.

[`timeDomain`](/documentation/AVFoundation/AVAudioTimePitchAlgorithm/timeDomain)

A modest quality time pitch algorithm that’s suitable for voice.

[`varispeed`](/documentation/AVFoundation/AVAudioTimePitchAlgorithm/varispeed)

A high-quality time pitch algorithm that doesn’t perform pitch correction.

### Initializers

[`init(rawValue:)`](/documentation/AVFoundation/AVAudioTimePitchAlgorithm/init(rawValue:))

Creates a new time pitch algorithm with a string.
