AKSystemSound

Simplifies playing caf audio files using AudioServicesPlaySystemSound. Audio files can also be scheduled to be played with a specified interval.

Features of this fork

The main feature is that the project is translated to ARC.

Methods are added

• Returns YES if any sound that was passed to this class is playing now.

[AKSystemSound isAnySoundPlaying];

• Stop playing on deallocation of corresponding object (unscheduled if was):

[AKSystemSound freeSoundWithName:@"ping"];

Usage

AKSystemSound uses the AudioServices API to play short alert sounds. These audio files have to be in the CAF-format.

• convert files to CAF using afconvert

afconvert -f caff -d LEI16 [input] out.caf

• play once

[[AKSystemSound soundWithName:@"ping"] play];

• schedule repeated playback

soundID = [[AKSystemSound soundWithName:@"ping"] scheduleRepeatWithInterval:5];

• schedule playback in delta time

soundID = [[AKSystemSound soundWithName:@"ping"] schedulePlayInInterval:5];

• schedule playback at specified date

soundID = [[AKSystemSound soundWithName:@"ping"] schedulePlayAtDate:date];

• unschedule

[AKSystemSound unscheduleSoundID:soundID];
soundID = AKSystemSoundInvalidID;

Notifications

• AKSystemSoundsWillPlay-/AKSystemSoundsDidPlayNotification Sent before and after a set of sounds are played. Good to have if you have any other audio playback (AudioQueue etc) and need to temporarily lower the output volume from that.

• AKSystemSoundWillPlay-/AKSystemSoundDidPlayNotification Sent before and after each sound is played.
