There is probably a General MIDI DLS on your OSX system already: /System/Library/Components/ponent/Contents/Resources/gs_instruments.dls. ![]() Some data formats (such as AC3) cannot be converted to a linear PCM. That is, a converter exists to convert data from the particular file format to any of the listed data formats. Each audio file type lists the data formats supported for that type. I’ve tried the MuseCore SoundFont and it sounds ok. This appendix describes the audio data and file formats supported in Core Audio in OS X v10.5. So do a web search for a GM SoundFont2 file. I’m not interested in copyright infringement, so I have not included either a DLS or SF2 file. The player also has a pre-roll prepareToPlay() function. You need to load a soundbank from a Soundfont or DLS file. Loading the player is similar to loading the AVAudioPlayer. You use AVMIDIPlayer to play standard MIDI files. Go to Table of Contents Playing a MIDI file You should do this in the code above right before you call play() on the player. Since we are playing an audio file, we should tell the session that is our intention by requesting that its category be AVAudioSessionCategoryPlayback, and then make the session active.

Open the Share Sheet and scroll to the end of the apps panel. Play and reduce the volume of other sounds Try AVAudioSession.sharedInstance().setCategory( The category can also be configured to play alongside any other sounds currently playing: // Play alongside other sounds try AVAudioSession.sharedInstance().setCategory( ![]() Your audio will be played by itself muting other audio, and your audio ignores the Silent switch and will continue even if the screen locks. Your audio will be played with other audio, if any other audio is playing, and your audio will be silenced by locking the screen and Silent switch.
