MATLAB 录音机和 wavwrite [关闭]

Question

在阅读website of MathWorks 时，我了解到他们不鼓励使用wavrecord 函数，因为它很快就会被弃用，所以我决定改用audiorecorder。一切都很好，甚至播放功能也在播放录制的音频，但是当我使用wavwrite 函数写入 wav 文件时听起来不太好，基本上我注意到持续时间设置不正确。

我正在展示程序，请建议我如何使它正确。谢谢。

fs = 44100
bits = 16
recObj = audiorecorder(fs, bits, 1);
%# get(recObj)

%# Collect a sample of your speech with a microphone, and plot the signal data:
%# Record your voice for 5 seconds.
recObj = audiorecorder;
disp('Start speaking.')
recordblocking(recObj, 5);
disp('End of Recording.');

%# Play back the recording.
play(recObj);

%# Store data in double-precision array.
myRecording = getaudiodata(recObj);
%disp(size(myRecording));

%# Plot the waveform.
plot(myRecording);

wavwrite(myRecording, fs, bits,'sample01_6k');
%#wavplay(myRecording,fs);

Answer 1

您创建了两次recObj，第二次创建它时，您使用默认设置而不是自定义设置创建它。删除对audiorecorder 的第二次调用，一切都应该按预期工作。
