```

## Discussion

Discussion The default property value is multichannel, which tells the player to spatialize any decodable multichannel layout. Setting the value to monoStereoAndMultichannel tells the player to spatialize any decodable mono, stereo, or multichannel layout. When this property value is monoAndStereo the player attempts to spatialize content tagged with a stereo channel layout (two-channel content with no layout specified as well as mono). This property isn’t key-value observable. important: It’s incorrect to render binaural recordings with spatialization. Content tagged with a binaural channel layout ignores this property value.
