Class AVAudioMixerNode

  • All Implemented Interfaces:
    AVAudio3DMixing, AVAudioMixing, AVAudioStereoMixing, NSObject
    public class AVAudioMixerNode
extends AVAudioNode
implements AVAudioMixing
    AVAudioMixerNode A node that mixes its inputs to a single output. Mixers may have any number of inputs. The mixer accepts input at any sample rate and efficiently combines sample rate conversions. It also accepts any channel count and will correctly upmix or downmix to the output channel count.

        Description copied from interface: AVAudioMixing
        Returns the AVAudioMixingDestination object corresponding to specified mixer node and its input bus When a source node is connected to multiple mixers downstream, setting AVAudioMixing properties directly on the source node will apply the change to all the mixers downstream. If you want to set/get properties on a specific mixer, use this method to get the corresponding AVAudioMixingDestination and set/get properties on it. Note: - Properties set on individual AVAudioMixingDestination instances will not reflect at the source node level. - AVAudioMixingDestination reference returned by this method could become invalid when there is any disconnection between the source and the mixer node. Hence this reference should not be retained and should be fetched every time you want to set/get properties on a specific mixer. If the source node is not connected to the specified mixer/input bus, this method returns nil. Calling this on an AVAudioMixingDestination instance returns self if the specified mixer/input bus matches its connection point, otherwise, it returns nil.
