關(guān)于錄音反正都是調(diào)用系統(tǒng)的東西女轿，沒啥好說的蓉媳，直接上流程
var recorder:AVAudioRecorder? //錄音器
var recorderSeetingsDic:[String : Any]! //錄音器設(shè)置參數(shù)數(shù)組
var volumeTimer:Timer! //定時(shí)器線程岭粤，循環(huán)監(jiān)測錄音的音量大小
var aacPath:String! //錄音存儲(chǔ)路徑
let docDir = NSSearchPathForDirectoriesInDomains(.documentDirectory,
.userDomainMask, true)[0]//獲取手機(jī)根目錄
var musicPlayer = AVAudioPlayer()//播放器
//初始化錄音器
let session:AVAudioSession = AVAudioSession.sharedInstance()
//設(shè)置錄音類型
try! session.setCategory(AVAudioSessionCategoryPlayAndRecord)
//初始化字典并添加設(shè)置參數(shù)
recorderSeetingsDic =
[
AVFormatIDKey: NSNumber(value: kAudioFormatMPEG4AAC),
AVNumberOfChannelsKey: 2, //錄音的聲道數(shù)，立體聲為雙聲道

AVEncoderBitRateKey : 320000,

判斷路徑文件夾是否存在

print(aacPath)

//準(zhǔn)備錄音
recorder!.prepareToRecord()
//開始錄音

//錄音器釋放

錄音的使用大致就是這樣实柠，只是還有小部分代碼沒有放上來姥宝，不過基本的流程就是這樣的，等我時(shí)間充裕點(diǎn)再把錄音單獨(dú)從項(xiàng)目里面拿出來其骄。
