### Building predicates

[`predicate(forAudioSampleRate:mediaSelectionOption:operatorType:)`](/documentation/AVFoundation/AVAssetVariantQualifier/predicate(forAudioSampleRate:mediaSelectionOption:operatorType:))

Creates a predicate for audio sample rate.

[`predicate(forAudioSampleRate:operatorType:)`](/documentation/AVFoundation/AVAssetVariantQualifier/predicate(forAudioSampleRate:operatorType:))

Creates a NSPredicate for audio sample rate which can be used with other NSPredicates to express variant preferences.

[`predicate(forBinauralAudio:)`](/documentation/AVFoundation/AVAssetVariantQualifier/predicate(forBinauralAudio:))

Creates a NSPredicate for binaural which can be used with other NSPredicates to express variant preferences.

[`predicate(forBinauralAudio:mediaSelectionOption:)`](/documentation/AVFoundation/AVAssetVariantQualifier/predicate(forBinauralAudio:mediaSelectionOption:))

Creates a predicate for binaural audio.

[`predicate(forChannelCount:mediaSelectionOption:operatorType:)`](/documentation/AVFoundation/AVAssetVariantQualifier/predicate(forChannelCount:mediaSelectionOption:operatorType:))

Creates a predicate with a channel count, media selection option, and operator type.

[`predicate(forChannelCount:operatorType:)`](/documentation/AVFoundation/AVAssetVariantQualifier/predicate(forChannelCount:operatorType:))

Creates a NSPredicate for audio channel count which can be used with other NSPredicates to express variant preferences.

[`predicate(forDownmixAudio:)`](/documentation/AVFoundation/AVAssetVariantQualifier/predicate(forDownmixAudio:))

Creates a NSPredicate for immersive audio which can be used with other NSPredicates to express variant preferences.

[`predicate(forDownmixAudio:mediaSelectionOption:)`](/documentation/AVFoundation/AVAssetVariantQualifier/predicate(forDownmixAudio:mediaSelectionOption:))

Creates a predicate for downmix audio.

[`predicate(forImmersiveAudio:)`](/documentation/AVFoundation/AVAssetVariantQualifier/predicate(forImmersiveAudio:))
