# trailingFrames

The number of trailing frames of input audio data required by the converter to perform high-quality conversion. Trailing frames follow, in time, the expected final input frame. Your application should be prepared to provide this number of additional input frames except when using the `kConverterPrimeMethod_None` value for the `kAudioConverterPrimeMethod` property. If no additional frames are available in the input stream (because, for example, the desired end frame is at the end of an audio file), then the audio converter synthesizes a sufficient number of silent (`0`-valued) trailing frames.

```
var trailingFrames: UInt32
