保存和访问录音 [英] Saving and accessing audio recordings

问题描述

好吧，这对Objective-C来说是一种新事物.我使用AVAudioRecorder设置了一个录音机.效果很好.但是....我不知道如何访问已保存的文件，哎呀，我什至不知道它们是否被保存了.该程序至少暂时将它们保存在NSDocumentsDirectory下，名称为"sounds.caf".我想知道是否将这些永久保存，否则如何保存.保存之后，我该如何访问它们.谢谢您的帮助.

Ok so im kind of new to objective-c. I set up an audio recorder using AVAudioRecorder. It works great. but.... i dont know how to access the saved files, heck i dont even know if they get saved. The program is saving them to NSDocumentsDirectory under the name "sounds.caf" at least temporarily. I want to know if these are being permanently saved, if not, then how can i make it so. And then how can i access them after they are saved. Thanks for the help.

作为旁注id，我想知道是否可以合并两个声音文件并将它们记录到一个新文件中.

Also as a side note id like to know if its possible to combine two sound files and record them together into a new file.

推荐答案

您可以使用以下代码保存音频文件.

You can use below code for saving your audio files.

#define DOCUMENTS_FOLDER [NSHomeDirectory() stringByAppendingPathComponent:@"Documents"]
#define DOCUMENTS_FOLDER1 [DOCUMENTS_FOLDER stringByAppendingPathComponent:@"Recordering"]
#define FILEPATH [DOCUMENTS_FOLDER stringByAppendingPathComponent:[self dateString]]


BOOL success = [self.myRecorder startRecording:FILEPATH];

if (!success){

   printf("Error starting recording\n");

   [self.myRecorder stopRecording];

   self.myRecorder = nil;

   isRecording = NO;

   return;

}
