<h2 id="开篇"><a href="#开篇" class="headerlink" title="开篇"></a>开篇</h2><p>最近在学习<code>AV Foundation</code> 试图把学习内容记录下来 并参考一些博客文章<br>本期的内容是<code>AVAudioPlayer</code></p>

<p>音频文件的生成过程是将声音信息<strong>采样</strong>、<strong>量化</strong>和<strong>编码</strong>产生的数字信号的过程，<strong>人耳所能听到的声音，最低的频率是从20Hz起一直到最高频率20KHZ</strong>，因此音频文件格式的最大带宽是20KHZ。根据<a href="https://zh.wikipedia.org/wiki/%E5%A5%88%E5%A5%8E%E6%96%AF%E7%89%B9%E9%A2%91%E7%8E%87" target="_blank" rel="external">奈奎斯特</a>的理论，只有采样频率高于声音信号最高频率的两倍时，才能把数字信号表示的声音还原成为原来的声音，所以音频文件的采样率一般在<strong>40~50KHZ</strong>，比如最常见的CD音质采样率<strong>44.1KHZ</strong>。 (所以一般大家都觉得CD音质是最好的.) 对声音进行采样、量化过程被称为<a href="https://zh.wikipedia.org/wiki/%E8%84%88%E8%A1%9D%E7%B7%A8%E8%99%9F%E8%AA%BF%E8%AE%8A" target="_blank" rel="external">脉冲编码调制</a>（Pulse Code Modulation），简称PCM。PCM数据是最原始的音频数据完全无损，所以PCM数据虽然音质优秀但体积庞大，为了解决这个问题先后诞生了一系列的音频格式，这些音频格式运用不同的方法对音频数据进行压缩，其中有无损压缩（ALAC、APE、FLAC）和有损压缩（MP3、AAC、OGG、WMA）两种 来源:<a href="http://msching.github.io/blog/2014/07/07/audio-in-ios/" target="_blank" rel="external">iOS音频播放 (一)：概述</a> by <a href="http://msching.github.io/" target="_blank" rel="external">码农人生</a></p>
</blockquote>
<p>–</p>
<p>我觉得程寅大牛的处理音频说的很明白<br>大神列出一个经典的音频播放流程（以MP3为例）</p>
<ol>
<li>读取MP3文件</li>
<li>解析采样率、码率、时长等信息，分离MP3中的音频帧</li>
<li>对分离出来的音频帧解码得到PCM数据</li>
<li>对PCM数据进行音效处理（均衡器、混响器等，非必须）</li>
<li>把PCM数据解码成音频信号</li>
<li>把音频信号交给硬件播放</li>
<li>重复1-6步直到播放完成</li>
</ol>
<p>在iOS系统中apple对上述的流程进行了封装并提供了不同层次的接口<br><img src="https://developer.apple.com/library/content/documentation/MusicAudio/Conceptual/CoreAudioOverview/Art/core_audio_layers_2x.png" alt=""> </p>
<blockquote>
<p>这是CoreAudio的接口层次 </p>
</blockquote>
<p>下面对其中的中高层接口进行功能说明：</p>
<ul>
<li>Audio File Services：读写音频数据，可以完成播放流程中的第2步；</li>
<li>Audio File Stream Services：对音频进行解码，可以完成播放流程中的第2步；</li>
<li>Audio Converter services：音频数据转换，可以完成播放流程中的第3步；</li>
<li>Audio Processing Graph Services：音效处理模块，可以完成播放流程中的第4步；</li>
<li>Audio Unit Services：播放音频数据：可以完成播放流程中的第5步、第6步；</li>
<li>Extended Audio File Services：Audio File Services和Audio </li>
<li>Converter services的结合体；</li>
<li>AVAudioPlayer/AVPlayer(AVFoundation)：高级接口，可以完成整个音频播放的过程（包括本地文件和网络流播放，第4步除外）；</li>
<li>Audio Queue Services：高级接口，可以进行录音和播放，可以完成播放流程中的第3、5、6步；</li>
<li>OpenAL：用于游戏音频播放，暂不讨论</li>
</ul>
<p>可以看到apple提供的接口类型非常丰富，可以满足各种类别类需求： </p>
<ul>
<li><p>如果你只是想实现音频的播放，没有其他需求AVFoundation会很好的满足你的需求。它的接口使用简单、不用关心其中的细节；</p>
</li>
<li><p>如果你的app需要对音频进行流播放并且同时存储，那么AudioFileStreamer加AudioQueue能够帮到你，你可以先把音频数据下载到本地，一边下载一边用NSFileHandler等接口读取本地音频文件并交给AudioFileStreamer或者AudioFile解析分离音频帧，分离出来的音频帧可以送给AudioQueue进行解码和播放。如果是本地文件直接读取文件解析即可。（这两个都是比较直接的做法，这类需求也可以用AVFoundation+本地server的方式实现，AVAudioPlayer会把请求发送给本地server，由本地server转发出去，获取数据后在本地server中存储并转送给AVAudioPlayer。另一个比较trick的做法是先把音频下载到文件中，在下载到一定量的数据后把文件路径给AVAudioPlayer播放，当然这种做法在音频seek后就回有问题了。）</p>
</li>
<li>如果你正在开发一个专业的音乐播放软件，需要对音频施加音效（均衡器、混响器），那么除了数据的读取和解析以外还需要用到AudioConverter来把音频数据转换成PCM数据，再由AudioUnit+AUGraph来进行音效处理和播放（但目前多数带音效的app都是自己开发音效模块来坐PCM数据的处理，这部分功能自行开发在自定义性和扩展性上会比较强一些。PCM数据通过音效器处理完成后就可以使用AudioUnit播放了，当然AudioQueue也支持直接使对PCM数据进行播放。）。下图描述的就是使用AudioFile + AudioConverter + AudioUnit进行音频播放的流程</li>
</ul>

<h2 id="使用AVAudioPlayer之前对AudioSession简介"><a href="#使用AVAudioPlayer之前对AudioSession简介" class="headerlink" title="使用AVAudioPlayer之前对AudioSession简介"></a>使用<code>AVAudioPlayer</code>之前对AudioSession简介</h2><blockquote>
<p><code>AVAudioSession</code>负责管理音频会话 它是个单例 在应用程序和操作系统之间负责中间人的角色 <a href="http://msching.github.io/blog/2014/07/08/audio-in-ios-2/" target="_blank" rel="external">AudioSession参考</a> </p>
</blockquote>
<p><code>AVAudioSession</code>主要功能包括以下几点：</p>
<ul>
<li>app是如何使用的音频服务 播放 还是录制 之类的</li>
<li>控制协调app输入输出设备（比如 麦克风，耳机、手机外放比如蓝牙连接一个外置音响 或airplay）</li>
<li>协调你的app的音频播放和系统以及其他app行为（例如有电话时需要打断，电话结束时需要恢复，按下静音按钮时是否歌曲也要静音等）</li>

<p>这里说一下<code>[audioPlayer prepareToPlay]</code><br><strong>调用这个函数是为了取得需要的音频硬件并预加载<code>Audio Queue</code>的缓冲区.</strong> 当然也可以不调用这个方法直接调用 <code>[audioPlayer play]</code>，但当 <strong>调用<code>play</code>方法时也会隐性激活</strong>,调用<code>prepareToPlay</code>是为了减少 创建播放器时预设加载和听到声音输出之间的延时 </p>

<p>先说<code>handleInterruption</code>意外情况下中断比如我按住home键使用siri<br>我会收到意外打断的通知当 type == <code>AVAudioSessionInterruptionTypeBegan</code>时 我们停止音乐播放或者暂停.<br>当type != <code>AVAudioSessionInterruptionTypeBegan</code>的时候一定是<code>AVAudioSessionInterruptionTypeEnded</code>这个时候<code>notification.userInfo</code>里面包含一个<code>AVAudioSessionInterruptionOptions</code>值来表明音频会话是否已经重新激活以及是否可以再次播放</p>
<p><strong><em>注:这个地方遇到个坑</em></strong> 当意外中断时候有时音频会话会很不灵敏 后来发现这种情况下需要重新激活会话 如下代码:</p>
<figure class="highlight objc"><table><tr><td class="gutter"><pre><div class="line">1</div></pre></td><td class="code"><pre><div class="line">[[<span class="built_in">AVAudioSession</span> sharedInstance] setActive:<span class="literal">YES</span> withOptions:<span class="built_in">AVAudioSessionSetActiveOptionNotifyOthersOnDeactivation</span> error:&error];</div></pre></td></tr></table></figure>
<p>这里<code>AVAudioSessionSetActiveOptionNotifyOthersOnDeactivation</code>是为了通知其它应用会话被我激活了 很多播放器开发者很不讲究 每次从来不用这个方法导致每次别人播放完音频 自己都收不到音频重新播放的信息 建议大家以和为贵, 写良心代码.</p>
<p>因为我外接的小米蓝牙音响发现还是不好使 最后又补上了<code>AVAudioSessionCategoryOptionAllowBluetooth</code>这个 </p>
<p><strong>激活音频会话 允许外接音响</strong></p>
<figure class="highlight objc"><table><tr><td class="gutter"><pre><div class="line">1</div></pre></td><td class="code"><pre><div class="line">[[<span class="built_in">AVAudioSession</span> sharedInstance] setCategory:<span class="built_in">AVAudioSessionCategoryPlayback</span> withOptions:<span class="built_in">AVAudioSessionCategoryOptionAllowBluetooth</span> error:<span class="literal">nil</span>];</div></pre></td></tr></table></figure>
<p>就好使了</p>
<p>下面说一下耳机插拔或者USB麦克风断开 Apple有个什么<code>Human Interface Guidelines(HIG)</code>相关定义 意思是说当硬件耳机拔出时建议 暂停播放音乐或者麦克风断开时。就是处于静音状态。是为了保密播放内容不被外界听到,不管苹果啥规定 我们都得照办 否则就得被拒。</p>
<figure class="highlight objc"><table><tr><td class="gutter"><pre><div class="line">1</div><div class="line">2</div><div class="line">3</div><div class="line">4</div><div class="line">5</div><div class="line">6</div><div class="line">7</div><div class="line">8</div><div class="line">9</div><div class="line">10</div><div class="line">11</div><div class="line">12</div><div class="line">13</div><div class="line">14</div><div class="line">15</div><div class="line">16</div></pre></td><td class="code"><pre><div class="line">- (<span class="keyword">void</span>)hanldeRouteChange:(<span class="built_in">NSNotification</span> *)notification {</div><div class="line"><span class="built_in">NSDictionary</span> *info = notification.userInfo;</div><div class="line"><span class="built_in">AVAudioSessionRouteChangeReason</span> reason = [info[<span class="built_in">AVAudioSessionRouteChangeReasonKey</span>] unsignedIntegerValue];</div><div class="line"><span class="comment">//老设备不可用</span></div><div class="line"><span class="keyword">if</span> (reason == <span class="built_in">AVAudioSessionRouteChangeReasonOldDeviceUnavailable</span>) {</div><div class="line"><span class="built_in">AVAudioSessionRouteDescription</span> *previousRoute = info[<span class="built_in">AVAudioSessionRouteChangePreviousRouteKey</span>];</div><div class="line"><span class="built_in">AVAudioSessionPortDescription</span> *previousOutput = previousRoute.outputs[<span class="number">0</span>];</div><div class="line"><span class="built_in">NSString</span> *portType = previousOutput.portType;</div><div class="line"><span class="keyword">if</span> ([portType isEqualToString:<span class="built_in">AVAudioSessionPortHeadphones</span>]) {</div><div class="line">[<span class="keyword">self</span> stop];</div><div class="line"><span class="keyword">self</span>.playButton.selected = <span class="literal">NO</span>;</div><div class="line">}</div><div class="line"></div><div class="line">}</div><div class="line"></div><div class="line">}</div></pre></td></tr></table></figure>
<p>这需要用<code>AVAudioSessionRouteChangeReasonKey</code>取出线路切换的原因<code>AVAudioSessionRouteChangeReason</code> 原因有这么多</p>
<figure class="highlight objc"><table><tr><td class="gutter"><pre><div class="line">1</div><div class="line">2</div><div class="line">3</div><div class="line">4</div><div class="line">5</div><div class="line">6</div><div class="line">7</div><div class="line">8</div><div class="line">9</div><div class="line">10</div><div class="line">11</div></pre></td><td class="code"><pre><div class="line"><span class="keyword">typedef</span> <span class="built_in">NS_ENUM</span>(<span class="built_in">NSUInteger</span>, <span class="built_in">AVAudioSessionRouteChangeReason</span>)</div><div class="line">{</div><div class="line"><span class="built_in">AVAudioSessionRouteChangeReasonUnknown</span> = <span class="number">0</span>,</div><div class="line"><span class="built_in">AVAudioSessionRouteChangeReasonNewDeviceAvailable</span> = <span class="number">1</span>,</div><div class="line"><span class="built_in">AVAudioSessionRouteChangeReasonOldDeviceUnavailable</span> = <span class="number">2</span>,</div><div class="line"><span class="built_in">AVAudioSessionRouteChangeReasonCategoryChange</span> = <span class="number">3</span>,</div><div class="line"><span class="built_in">AVAudioSessionRouteChangeReasonOverride</span> = <span class="number">4</span>,</div><div class="line"><span class="built_in">AVAudioSessionRouteChangeReasonWakeFromSleep</span> = <span class="number">6</span>,</div><div class="line"><span class="built_in">AVAudioSessionRouteChangeReasonNoSuitableRouteForCategory</span> = <span class="number">7</span>,</div><div class="line"><span class="built_in">AVAudioSessionRouteChangeReasonRouteConfigurationChange</span> <span class="built_in">NS_ENUM_AVAILABLE_IOS</span>(<span class="number">7</span>_0) = <span class="number">8</span></div><div class="line">} <span class="built_in">NS_AVAILABLE_IOS</span>(<span class="number">6</span>_0);</div></pre></td></tr></table></figure>
<p>我们需要这个<code>AVAudioSessionRouteChangeReasonOldDeviceUnavailable</code> 判断是否是旧设备<br>通过<code>AVAudioSessionRouteChangePreviousRouteKey</code>拿出</p>
<p><code>AVAudioSessionRouteDescription</code>描述信息<br><code>previousRoute</code> 在通过<br><code>previousRoute.outputs[0]</code>拿出<code>AVAudioSessionPortDescription</code></p>
<p>拿出<code>NSString *portType = previousOutput.portType</code></p>
<p>如果<code>[portType isEqualToString:AVAudioSessionPortHeadphones]</code></p>
<p>如果是耳机<code>AVAudioSessionPortHeadphones</code>则暂停播放</p>
<p>以上就是中断和线路切换的一些代码逻辑</p>
<p>下面我介绍一些好玩的</p>
<p><img src="https://raw.githubusercontent.com/sunyazhou13/sunyazhou13.github.io-images/master/Learning%20AV%20Foundation2AVAudioPlayer/IMG_2090.PNG" alt=""></p>
<p>前面说的一些后台设置信息显示的内容就是上图所示 在锁屏的时候显示</p>
<p>但是大家一定很奇怪的是怎么实现接收 <strong>锁屏状态下 点击 上一曲 暂停/播放 下一曲等操作</strong></p>
<p>需要在AppDelegate里面写上</p>
<figure class="highlight objc"><table><tr><td class="gutter"><pre><div class="line">1</div><div class="line">2</div><div class="line">3</div><div class="line">4</div><div class="line">5</div><div class="line">6</div><div class="line">7</div><div class="line">8</div><div class="line">9</div><div class="line">10</div><div class="line">11</div><div class="line">12</div><div class="line">13</div><div class="line">14</div><div class="line">15</div><div class="line">16</div></pre></td><td class="code"><pre><div class="line">- (<span class="built_in">BOOL</span>)application:(<span class="built_in">UIApplication</span> *)application didFinishLaunchingWithOptions:(<span class="built_in">NSDictionary</span> *)launchOptions {</div><div class="line"></div><div class="line"><span class="built_in">AVAudioSession</span> *session = [<span class="built_in">AVAudioSession</span> sharedInstance];</div><div class="line"><span class="built_in">NSError</span> *error;</div><div class="line"><span class="keyword">if</span> (![session setCategory:<span class="built_in">AVAudioSessionCategoryPlayback</span> error:&error]) {</div><div class="line"><span class="built_in">NSLog</span>(<span class="string">@"Category Error: %@"</span>, [error localizedDescription]);</div><div class="line">}</div><div class="line"></div><div class="line"><span class="keyword">if</span> (![session setActive:<span class="literal">YES</span> error:&error]) {</div><div class="line"><span class="built_in">NSLog</span>(<span class="string">@"Activation Error: %@"</span>, [error localizedDescription]);</div><div class="line">}</div><div class="line"></div><div class="line">[[<span class="built_in">UIApplication</span> sharedApplication] beginReceivingRemoteControlEvents];</div><div class="line">[<span class="keyword">self</span> becomeFirstResponder];</div><div class="line"><span class="keyword">return</span> <span class="literal">YES</span>;</div><div class="line">}</div></pre></td></tr></table></figure>
<p>这<code>[[UIApplication sharedApplication] beginReceivingRemoteControlEvents];</code><br>行代码 以及调用自己为 <code>[self becomeFirstResponder];</code>第一响应者 这样写是为了应用响应音频播放 后台切换或者中断的时候更灵敏.</p>
<figure class="highlight objc"><table><tr><td class="gutter"><pre><div class="line">1</div><div class="line">2</div><div class="line">3</div></pre></td><td class="code"><pre><div class="line">- (<span class="built_in">BOOL</span>)canBecomeFirstResponder {</div><div class="line"><span class="keyword">return</span> <span class="literal">YES</span>;</div><div class="line">}</div></pre></td></tr></table></figure>
<p>然后 写上如下代码 处理<strong>锁屏状态下 点击 上一曲 暂停/播放 下一曲等操作</strong></p>
<figure class="highlight objc"><table><tr><td class="gutter"><pre><div class="line">1</div><div class="line">2</div><div class="line">3</div><div class="line">4</div><div class="line">5</div><div class="line">6</div><div class="line">7</div><div class="line">8</div><div class="line">9</div><div class="line">10</div><div class="line">11</div><div class="line">12</div><div class="line">13</div><div class="line">14</div><div class="line">15</div><div class="line">16</div><div class="line">17</div><div class="line">18</div><div class="line">19</div><div class="line">20</div><div class="line">21</div></pre></td><td class="code"><pre><div class="line">- (<span class="keyword">void</span>)remoteControlReceivedWithEvent:(<span class="built_in">UIEvent</span> *)event {</div><div class="line"><span class="keyword">if</span> (event.type == <span class="built_in">UIEventTypeRemoteControl</span>) {</div><div class="line"><span class="keyword">switch</span> (event.subtype) {</div><div class="line"><span class="keyword">case</span> <span class="built_in">UIEventSubtypeRemoteControlPlay</span>:</div><div class="line"><span class="built_in">NSLog</span>(<span class="string">@"暂停播放"</span>);</div><div class="line"><span class="keyword">break</span>;</div><div class="line"><span class="keyword">case</span> <span class="built_in">UIEventSubtypeRemoteControlPause</span>:</div><div class="line"></div><div class="line"><span class="built_in">NSLog</span>(<span class="string">@"继续播放"</span>);</div><div class="line"><span class="keyword">break</span>;</div><div class="line"><span class="keyword">case</span> <span class="built_in">UIEventSubtypeRemoteControlNextTrack</span>:</div><div class="line"><span class="built_in">NSLog</span>(<span class="string">@"下一曲"</span>);</div><div class="line"><span class="keyword">break</span>;</div><div class="line"><span class="keyword">case</span> <span class="built_in">UIEventSubtypeRemoteControlPreviousTrack</span>:</div><div class="line"><span class="built_in">NSLog</span>(<span class="string">@"上一曲"</span>);</div><div class="line"><span class="keyword">break</span>;</div><div class="line"><span class="keyword">default</span>:</div><div class="line"><span class="keyword">break</span>;</div><div class="line">}</div><div class="line">}</div><div class="line">}</div></pre></td></tr></table></figure>
<p>剩余逻辑大家自己填充吧我就不介绍了. </p>
<p>好了AVAudioPlayer就到这吧！有啥疑问大家可以评论留言都能看到或者指正我的错误。我会及时改正.</p>
