在右音频记录 [英] Audio record in R

问题描述

我与R中一些音频和声音包的Windows（我的是Win7的X64）播放。还有，当我试图使用记录从麦克风录制的一个问题（）{}音频：

I am playing with some audio and sound packages in R for Windows (mine is Win7 x64). There is a problem when I tried to record from microphone using record() {audio} :

• 这可能只记录一次，然后无法记录更多一些，直到重新启动整个控制台


• 声音一旦被记录下来，它可以被保存，但不能播放（）


• 从上面记录的文件不能被读取的音频，但由于不完整的波形文件
调谐器


• 和下面的文件名不工作

• it could record only once then cannot record some more until restart the whole console
• once sound is recorded, it could be save but cannot play()
• file recorded from above cannot be read by audio, but tuneR due to 'incomplete wave file'

• and the following "filename" does not work

文件名= paste0（'ABCD'，'。WAV）
save.wave（X，文件名）

filename=paste0('abcd','.wav') save.wave(x,filename)

直到直接将命令类型类似，这使得难写一个脚本记录/功能

until type directly to the command like, this makes hard to write a record script/function

save.wave(x,'abc.wav')

我想，如果你遇到了同样的问题问在Win人使用的音频包和另一个操作系统。谢谢你。

I want to ask anyone used audio package in Win and another OS if you met the same problem. Thanks.

推荐答案

我刚写了记录功能。它的工作原理，但运行时间后，该程序已被关闭，然后打开R-又说：

I just wrote a function for record. It works but after a running time, the program has to be closed and then open R again:

audiorec=function(kk,f){  # kk: time length in seconds; f: filename
if(f %in% list.files()) 
{file.remove(f); print('The former file has been replaced');}
require(audio)
s11 <- rep(NA_real_, 16000*kk) # rate=16000
record(s11, 16000, 1)  # record in mono mode
wait(kk)
save.wave(s11,f)
}

的GUI仍是一个问题。我试着用Win7的其他电脑，但遇到了同样的错误。有一些错误，我还没有想通了。

Still a problem of GUI. I tried with some other computer using Win7 but met the same error. There is some bugs, I haven't figured it out.
