iOS-音视频(八) : Speex格式实现语音聊天功能

Posted on by SailorGa

前言:语音技术近来可是出遍了风头，从iphone5s的siri，到微信的语音聊天等等，极大地方便了人们的社交生活，也体现了当今移动科技发展的迅猛。当然，作为一位移动开发的从业人员怎能落伍呢！今天我们就来简单的实现一下语音聊天的功能。

 

这次Demo使用的是Speex对录制的声音进行语音压缩，并且进行ogg的封装。由于本人水平有限，尝试了几次对ogg库的编译都不成功，于是终于在Code4App上找到了一个Demo,把它的speex和封装好的ogg拿了过来!

 

 

 

 

源码如下:

#import <UIKit/UIKit.h>

#import “RecorderManager.h”

#import “PlayerManager.h”

 

@interface MainViewController : UIViewController<UITableViewDataSource, UITableViewDelegate, RecordingDelegate, PlayingDelegate, UIGestureRecognizerDelegate>

 

– (IBAction)talk:(id)sender;

 

@property (strong, nonatomic) IBOutlet UITableView *vTableView;

 

@property (strong, nonatomic) IBOutlet UIButton *speekBtb;

 

@property (assign) BOOL isSpeak;

 

@property (strong, nonatomic) NSMutableArray *voiceArray;

 

@property (strong, nonatomic) NSString *fileName;

 

@property (assign) BOOL isPlaying;

 

@end

 

#import <UIKit/UIKit.h>

#import “RecorderManager.h”

#import “PlayerManager.h”

 

@interface MainViewController : UIViewController<UITableViewDataSource, UITableViewDelegate, RecordingDelegate, PlayingDelegate, UIGestureRecognizerDelegate>

 

– (IBAction)talk:(id)sender;

 

@property (strong, nonatomic) IBOutlet UITableView *vTableView;

 

@property (strong, nonatomic) IBOutlet UIButton *speekBtb;

 

@property (assign) BOOL isSpeak;

 

@property (strong, nonatomic) NSMutableArray *voiceArray;

 

@property (strong, nonatomic) NSString *fileName;

 

@property (assign) BOOL isPlaying;

 

@end

 

实现：

#import “MainViewController.h”

 

@interface MainViewController()

 

@end

 

@implementation MainViewController

@synthesize isSpeak = _isSpeak;

@synthesize voiceArray = _voiceArray;

@synthesize fileName = _fileName;

@synthesize isPlaying = _isPlaying;

    guesture.delegate = self;

    guesture.minimumPressDuration = 0.01f;

    

    录音按钮添加手势操作

好了一个简单的语音聊天程序就好了，是不是很简单，其中最重要的就是 RecorderManager以及PlayerManager两个类了，一个负责录音，一个负责播放，这两个类我准备放到下一篇博客中讲解一下，大家不妨通过去下载我的Demo自己动手试一试，下载地址：(有积分的可以下载下,不过有的是老demo会报错)

注意点：

1.在将Demo程序中的Classes以及Libs文件加入到工程中去的时候，请将echo_diagnostic.m文件以及以test开头的文件删掉，否则工程会报错。

2.在工程中将Preprocessor Macros选项中的内容删除。
