MATLAB audiorecorder和wavwrite

Question

在閱讀website of MathWorks時，我瞭解到他們不鼓勵使用wavrecord函數，因爲它很快就會被棄用，所以我決定改用audiorecorder。一切都很好，連播放功能也被打了錄製的音頻，但是當我使用wavwrite功能寫信給它不是聽起來很好wav文件，基本上我注意到，持續時間設置不正確。

我表示通過上述程序，請建議我如何使它正確。謝謝。

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

要創建recObj兩次，創建它的第二次，你使用默認設置，而不是您的自定義設置，創建它。刪除第二個電話audiorecorder，一切都應按預期工作。
