Global Variable

kAudioFilePropertyReserveDuration

The duration in seconds of the data expected to be written. Set this property before any data has been written to reserve space in the file header for a packet table and other information to appear before the audio data. Otherwise, the packet table might get written at the end of the file, preventing the file from being streamable.

Declaration

var kAudioFilePropertyReserveDuration: AudioFilePropertyID { get }
