Matlab 音频播放器数组

发布于 2024-11-07 10:25:26 字数 557 浏览 1 评论 0原文

我正在labview 中创建一个matlab 脚本。在该脚本中，我尝试创建音频播放器对象的数组。但是，我遇到了错误，并且找不到解决方法。

这是脚本：

nrOfSounds = 11;
if (exist('p') == 0)
    [snd, freq, bps] = wavread('sounds/1.wav');
    p = audioplayer(snd, freq);
    for t=2:nrOfSounds
        [snd,freq,bps] = wavread(strcat('sounds/',num2str(t),'.wav'));
        s = audioplayer(snd,freq);
        p(end+1) = s;
    end
end

这就是错误：

Audioplayer objects cannot be concatenated.

似乎我无法创建音频播放器对象的数组，但我无法真正找到解决此问题的方法，因为我对 matlab 没有真正的经验。谁能帮我解决这个问题吗？

I am creating a matlab script inside labview. Inside that script I try to create an array of audioplayer objects. However, I got an error, and I can't find a way around it.

This is the script:

nrOfSounds = 11;
if (exist('p') == 0)
    [snd, freq, bps] = wavread('sounds/1.wav');
    p = audioplayer(snd, freq);
    for t=2:nrOfSounds
        [snd,freq,bps] = wavread(strcat('sounds/',num2str(t),'.wav'));
        s = audioplayer(snd,freq);
        p(end+1) = s;
    end
end

And this is the error:

Audioplayer objects cannot be concatenated.

It seems that I can't create an array of audioplayer objects, but I can't really find a way around this since I'm not really experienced with matlab. Can anyone help me with this?

您必须使用单元格，而不是数组。

nrOfSounds = 11;
if (exist('p') == 0)
    [snd, freq, bps] = wavread('sounds/1.wav');
    p{1} = audioplayer(snd, freq);
    for t=2:nrOfSounds
        [snd,freq,bps] = wavread(strcat('sounds/',num2str(t),'.wav'));
        s = audioplayer(snd,freq);
        p{end+1} = s;
    end
end

You have to use cells, not arrays.

nrOfSounds = 11;
if (exist('p') == 0)
    [snd, freq, bps] = wavread('sounds/1.wav');
    p{1} = audioplayer(snd, freq);
    for t=2:nrOfSounds
        [snd,freq,bps] = wavread(strcat('sounds/',num2str(t),'.wav'));
        s = audioplayer(snd,freq);
        p{end+1} = s;
    end
end
