AVAssetReaderAudioMixOutput

AVAssetReaderAudioMixOutput is a concrete subclass of AVAssetReaderOutput that defines an interface for reading audio samples that result from mixing the audio from one or more AVAssetTracks of an AVAssetReader's AVAsset.

Clients can read the audio data mixed from one or more asset tracks by adding an instance of AVAssetReaderAudioMixOutput to an AVAssetReader using the -[AVAssetReader addOutput:] method.

                                                                                                NSDictionary<java.lang.String,?> audioSettings)

assetReaderAudioMixOutputWithAudioTracks:audioSettings:

Returns an instance of AVAssetReaderAudioMixOutput for reading mixed audio from the specified audio tracks, with optional audio settings.

Each track must be one of the tracks owned by the target AVAssetReader's asset and must be of media type AVMediaTypeAudio.

For non-nil values of audioSettings, the audio settings dictionary must contain values for keys in AVAudioSettings.h (linear PCM only). Initialization will fail if the audio settings cannot be used with the specified tracks. AVSampleRateConverterAudioQualityKey is not supported.

A value of nil for audioSettings configures the output to return samples in a convenient uncompressed format, with sample rate and other properties determined according to the properties of the specified audio tracks as well as other considerations that may vary according to device capabilities, operating system version, and other factors. Therefore if you wish to perform any processing on the output, you must examine the CMAudioFormatDescription of the CMSampleBuffers that are provided in order to ensure that your processing is appropriately configured for the output format.

Parameters:

tracks - An NSArray of AVAssetTrack objects from which the created object should read sample buffers to be mixed.

audioSettings - An NSDictionary of audio settings to be used for audio output.

Returns:

An instance of AVAssetReaderAudioMixOutput.

audioMix

public AVAudioMix audioMix()

[@property] audioMix

The audio mix used by the receiver.

The value of this property is an AVAudioMix that can be used to specify how the volume of audio samples read from each source track will change over the timeline of the source asset.

This property cannot be set after reading has started.

audioSettings

public NSDictionary<java.lang.String,?> audioSettings()

[@property] audioSettings

The audio settings used by the receiver.

The value of this property is an NSDictionary that contains values for keys from AVAudioSettings.h (linear PCM only). A value of nil indicates that the receiver will return audio samples in a convenient uncompressed format, with sample rate and other properties determined according to the properties of the receiver's audio tracks.

audioTimePitchAlgorithm

public java.lang.String audioTimePitchAlgorithm()

[@property] audioTimePitchAlgorithm

Indicates the processing algorithm used to manage audio pitch for scaled audio edits.

Constants for various time pitch algorithms, e.g. AVAudioTimePitchAlgorithmSpectral, are defined in AVAudioProcessingSettings.h. An NSInvalidArgumentException will be raised if this property is set to a value other than the constants defined in that file.

The default value is AVAudioTimePitchAlgorithmSpectral.

audioTracks

public NSArray<? extends AVAssetTrack> audioTracks()

[@property] audioTracks

The tracks from which the receiver reads mixed audio.

The value of this property is an NSArray of AVAssetTracks owned by the target AVAssetReader's asset.

init

public AVAssetReaderAudioMixOutput init()

Overrides:

init in class AVAssetReaderOutput

initWithAudioTracksAudioSettings

public AVAssetReaderAudioMixOutput initWithAudioTracksAudioSettings(NSArray<? extends AVAssetTrack> audioTracks,
                                                                    NSDictionary<java.lang.String,?> audioSettings)

initWithAudioTracks:audioSettings:

Creates an instance of AVAssetReaderAudioMixOutput for reading mixed audio from the specified audio tracks, with optional audio settings.

Each track must be one of the tracks owned by the target AVAssetReader's asset and must be of media type AVMediaTypeAudio.

For non-nil values of audioSettings, the audio settings dictionary must contain values for keys in AVAudioSettings.h (linear PCM only). Initialization will fail if the audio settings cannot be used with the specified tracks. AVSampleRateConverterAudioQualityKey is not supported.

A value of nil for audioSettings configures the output to return samples in a convenient uncompressed format, with sample rate and other properties determined according to the properties of the specified audio tracks as well as other considerations that may vary according to device capabilities, operating system version, and other factors. Therefore if you wish to perform any processing on the output, you must examine the CMAudioFormatDescription of the CMSampleBuffers that are provided in order to ensure that your processing is appropriately configured for the output format.

Parameters:

tracks - An NSArray of AVAssetTrack objects from which the created object should read sample buffers to be mixed.

audioSettings - An NSDictionary of audio settings to be used for audio output.

Returns:

An instance of AVAssetReaderAudioMixOutput.

setAudioMix

public void setAudioMix(AVAudioMix value)

[@property] audioMix

The audio mix used by the receiver.

The value of this property is an AVAudioMix that can be used to specify how the volume of audio samples read from each source track will change over the timeline of the source asset.

This property cannot be set after reading has started.

setAudioTimePitchAlgorithm

public void setAudioTimePitchAlgorithm(java.lang.String value)

[@property] audioTimePitchAlgorithm

Indicates the processing algorithm used to manage audio pitch for scaled audio edits.

Constants for various time pitch algorithms, e.g. AVAudioTimePitchAlgorithmSpectral, are defined in AVAudioProcessingSettings.h. An NSInvalidArgumentException will be raised if this property is set to a value other than the constants defined in that file.

The default value is AVAudioTimePitchAlgorithmSpectral.
