[英]Finding the length of an audio recording in iPhone
I am recording the audio using avaudiorecorder. 我正在使用avaudiorecorder录制音频。 How do I find the length of the recording after saving the recording in a .caf file?
在.caf文件中保存录制文件后如何找到录制的长度?
You can use helpers in the CoreMedia framework. 您可以在CoreMedia框架中使用帮助程序。
AVURLAsset *asset = [[AVURLAsset alloc] initWithURL:avAudioRecorder.url options:nil];
CMTime time = asset.duration;
double durationInSeconds = CMTimeGetSeconds(time);
