标签: pyaudio

我正在运行Ubuntu 11.04,Python 2.7.1并想安装Pyaudio.所以我跑了,

$ sudo easy_install pyaudio

在终端和进程退出时出现以下错误消息,

我不确定是要在askubuntu.com上发布这个,还是在stackoveflow中发布,但无论如何它都在stackoverflow中.另外我google了一下这个问题,通过安装python-dev找到了解决了一些问题.我已经安装了python-dev.可能出了什么问题？

UPDATE

以下是安装libportaudio-dev后出现的新错误,

Searching for pyaudio …

我正在使用mac osx 10.10正如PyAudio主页所说,我使用了安装PyAudio

brew install portaudio 
pip install pyaudio

portaudio的安装似乎很成功,我可以在/ usr/local/include和/ usr/local/lib中找到头文件和库,但是当我尝试安装pyaudio时,它会给我一个错误

src/_portaudiomodule.c:29:10: fatal error: 'portaudio.h' file not found
#include "portaudio.h"
         ^
1 error generated.
error: command 'cc' failed with exit status 1

实际上它在/ usr/local/include中为什么找不到该文件？类似问题的一些答案对我不起作用(比如使用virtualenv,或者手动编译),我想找到一种简单的方法来解决这个问题.

我如何使用pyaudio检测来自现场麦克风的突然敲击声？

我正在使用PyAudio来录制麦克风的输入.

由于音频录制对我来说很好,我应该尝试简单地抑制其错误消息吗？还是有办法解决它们？

我正试图在python中进行实时绘图声音.我需要从麦克风上取下块.

使用PyAudio,尝试使用

import pyaudio
import wave
import sys

chunk = 1024
FORMAT = pyaudio.paInt16
CHANNELS = 1
RATE = 44100
RECORD_SECONDS = 5
WAVE_OUTPUT_FILENAME = "output.wav"

p = pyaudio.PyAudio()

stream = p.open(format = FORMAT,
                channels = CHANNELS,
                rate = RATE,
                input = True,
                frames_per_buffer = chunk)

print "* recording"
all = []
for i in range(0, RATE / chunk * RECORD_SECONDS):
    data = stream.read(chunk)
    all.append(data)
print "* done recording"

stream.close()
p.terminate()

之后,我得到了以下错误:

我在Ubuntu 10.10 x64中的Enthought Python Distribution(Python 2.6.6)下使用PyAudio.

>>> import pyaudio
>>> pa = pyaudio.PyAudio()
>>> pa.get_default_input_device_info()

Traceback (most recent call last):
  File "<pyshell#24>", line 1, in <module>
    pa.get_default_input_device_info()

    device_index = pa.get_default_input_device()
IOError: No Default Input Device Available

如果我尝试打开输入流,这是我得到的相同错误.存在相应的错误"IOError:No Default Output Device Available"

我第一次尝试:

pip install pyaudio

但有人告诉我

-bash: pip: command not found

然后我尝试了:

pip3 install pyaudio

然后我得到了:

src/_portaudiomodule.c:29:10: fatal error: 'portaudio.h' file not found

#include "portaudio.h"

         ^

1 error generated.

但我安装了portaudio

brew install portaudio

警告:已安装portaudio-19.20140130

那我该怎么办？非常感谢,这是我第一次使用pyaudio,所以.......

:)

当我尝试在 python-3.10.1 virtualenv（使用 python-3.9.0 venv 创建并升级）中使用 PyAudio-0.2.11 播放波形文件时，我收到了一个异常，没有播放任何内容，其他的一切正常。

Exception in thread WavPlayer:rsrc/sound.wav:

SystemError: PY_SSIZE_T_CLEAN macro must be defined for '#' formats

我不知道'#' format代表什么，我确信我的代码与 C API 无关，但它在 python-3.9.x 下运行良好，这是 PyAudio 库本身的问题吗？我该如何解决这个问题？

尝试按照这里的说明安装pyaudio :

我正在尝试用pip安装pyaudio:

pip install pyaudio

在virtualenv但我收到一个错误:
