# TemporalTransformer

A transformer that takes an asynchronous input sequence of temporal features and produces an asynchronous output  sequence.

## Declaration

```swift
protocol TemporalTransformer<Input, Output>
```

## Overview

Overview A temporal transformer, unlike a regular transformer, can accumulate multiple inputs before producing an output. For example, an audio transformer can accumulate audio buffers until the desired length is reached before producing an output.
