PyAudio ErrNo Input Overflowed -9981

问题 I was getting the same error as the user in Python, Error audio Recording in 16000Hz using Pyaudio The error was the same (except for the line numbers) as in the below graphic: As I was writing this, I found the solution to my problem in this link. The solution was to up the bitrate to 48000. But I had already "been approved" at 44100 if p.is_format_supported(44100.0, # Sample rate input_device=devinfo["index"], input_channels=devinfo['maxInputChannels'], input_format=pyaudio.paInt16): print

I'm currently facing a hard problem. I need to use Pyaudio on a french windows environnement and the name of the audio devices contains é or è by default.

Building PortAudio and PyAudio on Mac running Snow Leopard (arch issues)

由 孤街浪徒 提交于 2019-12-06 05:43:46
问题 I'd like to tell you what I've tried and then I'd really welcome any comments you can provide on how I can get PortAudio and PyAudio setup correctly! I've tried installing the stable and svn releases of PortAudio from their website for my Core 2 Duo MacBook Pro running Snow Leopard. The stable release has a sizeof error that can be fixed(?), but the daily svn release installs fine with ./configure && make && make install (so this is what I'm using). The tests are compiled properly and I can

Prevent ALSA underruns with PyAudio

由 风流意气都作罢 提交于 2019-12-05 21:47:42
I wrote a little program which records voice from the microphone and sends it over network and plays it there. I'm using PyAudio for this task. It works almost fine but on both computers i get errors from ALSA that an underrun occurred. I googled a lot about it and now I know what an underrun even is. But I still don't know how to fix the problem. Most of the time the sound is just fine. But it sounds a little bit strange if underruns occur. Is there anything I should take care of in my code? It feels like I'm doing an simple error and I miss it. My system: python: python3.3, OS: Linux Mint

I upgraded my Mac to macOS Sierra and I had to start a new account. Right now I am trying to establish my environment. I ran into a problem installing pyaudio. The procedure I used is first use homebrew and install port audio. brew install portaudio It installs with no errors. I proceed to install pyaudio using pip pip install pyaudio I receive the following error message. cc -fno-strict-aliasing -fno-common -dynamic -arch x86_64 -arch i386 -g -Os -pipe -fno-common -fno-strict-aliasing -fwrapv -DENABLE_DTRACE -DMACOSX -DNDEBUG -Wall -Wstrict-prototypes -Wshorten-64-to-32 -DNDEBUG -g -fwrapv

Having trouble installing PyAudio for Python3 on Mint

由 我们两清 提交于 2019-12-05 06:27:08
I was following the instructions here and I'm having trouble getting the installation to work. Basically, the first part works fine. I downloaded portaudio, followed the instructions, and it all seemed to work. However, when I tried python3 setup.py install , I got an error. The error came from the /src/_portaudiomodule.c file, and it said that "The file Python.h could not be found". I don't really understand what's going on because there was no Python.h file when I extracted the PyAudio archive. I don't know where the Python.h file was supposed to come from. I'm kind of a noob to unix systems
