iOS audio playing (both local and streaming) and recording made easy through a complete and block-driven Objective-C class. AFSoundManager uses AudioToolbox and AVFoundation frameworks to serve the audio.

##Installation

###CocoaPods

AFSoundManager is available on CocoaPods so you can get it by adding this line to your Podfile:

pod 'AFSoundManager'

###Manual

If you don't use CocoaPods, you will have to import these files into your project:

AFSoundManager.h
AFSoundPlayback.h
AFSoundPlayback.m
AFSoundItem.h
AFSoundItem.m
AFSoundQueue.h
AFSoundQueue.m
AFSoundRecord.h
AFSoundRecord.m
NSTimer+AFSoundManager.h
NSTimer+AFSoundManager.m

Also, you need to import AVFoundation, AudioToolbox and MediaPlayer frameworks.

##Roadmap

Since the v2.0 is a very first version, there's a lot of work remaining. This is a sneak peek of what's coming soon:

• Integration with Control Center and Locked Screen controls
• Improve data returning to give the developer more data about the current playing
• A brand new class to let AFSoundPlayback handle real time effects like delay, a customized EQ, etc.
• AFSoundManager-ready UI controls to integrate a fulfilled play control in your app at a glance, powered by AFSoundManager.

##Usage

###Playing a sound

AFSoundItem will take care of any sound item, and it will be handled by AFSoundPlayback. The AFSoundItem will contain the location and the metadata of each sound, song, chapter, etc.

AFSoundItem *item = [[AFSoundItem alloc] initWithLocalResource:@"demo.mp3" atPath:nil];
    
AFSoundPlayback *player = [[AFSoundPlayback alloc] initWithItem:item];
	
[player play];

[_queue listenFeedbackUpdatesWithBlock:^(AFSoundItem *item) {
        
    NSLog(@"Item duration: %ld - time elapsed: %ld", (long)item.duration, (long)item.timePlayed);
} andFinishedBlock:^(void) {
        
    NSLog(@"Track finished playing");
}];

###Playing a queue

So, an AFSoundItem object can be played individually, but it can also be part of a queue, managed by AFSoundQueue.

AFSoundItem *item1 = [[AFSoundItem alloc] initWithLocalResource:@"demo1.mp3" atPath:nil];
AFSoundItem *item2 = [[AFSoundItem alloc] initWithLocalResource:@"demo2.mp3" atPath:nil];
AFSoundItem *item3 = [[AFSoundItem alloc] initWithLocalResource:@"demo3.mp3" atPath:nil];

AFSoundQueue *queue = [[AFSoundQueue alloc] initWithItems:@[item1, item2, item3]];
[queue playCurrentItem];

[_queue listenFeedbackUpdatesWithBlock:^(AFSoundItem *item) {
        
    NSLog(@"Item duration: %ld - time elapsed: %ld", (long)item.duration, (long)item.timePlayed);
} andFinishedBlock:^(AFSoundItem *nextItem) {
        
    NSLog(@"Finished item, next one is %@", nextItem.title);
}];

The block will be executed each 1 second, returning a dictionary with info about the current item. Expect more info returned by the block in future releases, like the current item object (AFSoundItem), current queue index, etc.

###Current playing actions

####Standard

-(void)play;
-(void)pause;
-(void)restart;
-(void)playAtSecond:(NSInteger)second;

####Queue

-(void)playCurrentItem;
-(void)pause;
-(void)playNextItem;
-(void)playPreviousItem;
-(void)playItem:(AFSoundItem *)item;
-(void)playItemAtIndex:(NSInteger)index;

###Managing a queue

To manage a queue, you can both add items with -addItem: or addItem:atIndex: or remove items from the current queue with -removeItem: and -removeItemAtIndex:

###Fetching metadata

Since you'll be working with AFSoundItem to manage your tracks, you can obtain the metadata related like the title, album, artist and artwork.

[_queue listenFeedbackUpdatesWithBlock:^(AFSoundItem *item) {
        
    NSLog(@"Item duration: %ld - time elapsed: %ld", (long)item.duration, (long)item.timePlayed);
} andFinishedBlock:^(AFSoundItem *nextItem) {
        
    NSLog(@"Finished item, next one is %@, by %@ album from the album %@", nextItem.title, nextItem.artist, nextItem.album);
    
    [self updateArtwork:nextItem.artwork];
}];

###Recording a sound

As the previous version, AFSoundManager lets you record sound quickly thanks to AFSoundRecord:

AFSoundRecord *recorder = [[AFSoundRecord alloc] initWithFilePath:[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0]];

[recorder startRecording];
