的Python：什么是winsound.Beep的最近的Linux和OSX等价物？ [英] Python: what are the nearest Linux and OSX equivalents of winsound.Beep?

问题描述

如果一个人希望哔Windows上的扬声器，巨蟒显然2提供了一个有用的功能： winsound.Beep（）。关于此功能的妙处是，它需要的参数指定嘟嘟的精确频率和持续时间。这正是我想做的事情，但我不使用Windows。所以......

If one wishes to beep the speaker on Windows, Python 2 apparently provides a useful function: winsound.Beep(). The neat thing about this function is that it takes arguments specifying the exact frequency and duration of the beep. This is exactly what I want to do, except that I don't use Windows. So...

什么是 winsound.Beep（） Linux和OSX，带来尽可能少的依赖关系可能吗？

What are the nearest equivalents of winsound.Beep() for Linux and OSX, bringing in as few dependencies as possible?

请注意，我希望能够直接发出蜂鸣声扬声器，不播放声音文件。另外，我需要能够控制蜂鸣声的频率和持续时间，因此 curses.beep（）和打印'\\一个不会做。最后，我知道pygame的提供了大量的音功能，但考虑到我不需要任何的pygame的的其他功能，这似乎就像使用大锤牛刀（反正，我试图与依赖客场做尽可能）

Please note that I want to be able to beep the speaker directly, not to play a sound file. Also, I need to be able to control the frequency and duration of the beep, so curses.beep() and print '\a' won't do. Lastly, I am aware that PyGame provides extensive sound capabilities, but given that I don't require any of PyGame's other functionality, that would seem like using a sledgehammer to crack a nut (and anyway, I'm trying to do away with dependencies as far as possible).

它涉及直接写入到/ dev /音频。不知道怎么的便携式它或者如果它甚至还可以在所有 - 我不是在Linux机器ATM

It involves writing directly to /dev/audio. Not sure how portable it is or if it even works at all - i'm not on a linux machine atm.

def beep(frequency, amplitude, duration):
    sample = 8000
    half_period = int(sample/frequency/2)
    beep = chr(amplitude)*half_period+chr(0)*half_period
    beep *= int(duration*frequency)
    audio = file('/dev/audio', 'wb')
    audio.write(beep)
    audio.close()
