ios - Create a crossfader with AvAudioPlayer -


how can create crossfader between 2 sound track avaudioplayer?

i must use avaudiomix? but... how should use?

avaudioplayer not support using avaudiomix. try fade out playing directly setting playback volume getting timing right between 2 avaudioplayers difficult avaudioplayer known have high , unpredictable latency when starting play.

one way accomplish use avplayer , avplayeritem , avcomposition. can setup composition overlay 2 audio files desired amount , setup avaudiomix fade out first , fade in second. method let have precise control on when audio files play relative 1 another.
