I am receiving error messages every time I play a sound with PyAudio and am having trouble supressing them. ALSA lib pcm_dmix.c:1018:(snd_pcm_dmix_open) unable to open slave ALSA lib pcm.c:2217:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.rear ALSA lib pcm.c:2217:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.center_lfe ALSA lib pcm.c:2217:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.side bt_audio_service_open: connect() failed: Connection refused (111) bt_audio_service_open: connect() failed: Connection refused (111) bt_audio_service_open: connect() failed: Connection refused (111) bt_audio

Please do not report this question as a duplicate, because none of the already available Solution working for me, I tested them all So, I am trying to run a PyAudio sample Recording program in my RaspberryPi model B board, This is the error I am getting, Traceback (most recent call last): File "/home/pi/pyaudio/test/testing.py", line 23, in <module> data = stream.read(chunk) File "/usr/local/lib/python2.7/dist-packages/pyaudio.py", line 605, in read return pa.read_stream(self._stream, num_frames) IOError: [Errno Input overflowed] -9981 There are certain solutions already available that solved

I'd like to install pyaudio on osx lion but i'm unable to do it. Everytime i try with the pkg, it doesn't install anything. When i try to install it with pip i have the following error (among a lot of other lines) : lipo: can't open input file: /var/folders/11/gfpzwjdd6dj7hbz7dpbvx9y40000gn/T//ccYnQM1k.out (No such file or directory) error: command '/usr/bin/llvm-gcc' failed with exit status 1 If anyone can help me, thank you. Matthew Henry I had to manually install it to get anything working. You'll need the source distributions for both pyaudio and portaudio. Firstly I installed portaudio

How do you remove "popping" and "clicking" sounds in audio constructed by concatenating sound tonal sound clips together? I have this PyAudio code for generating a series of tones: import time import math import pyaudio class Beeper(object): def __init__(self, **kwargs): self.bitrate = kwargs.pop('bitrate', 16000) self.channels = kwargs.pop('channels', 1) self._p = pyaudio.PyAudio() self.stream = self._p.open( format = self._p.get_format_from_width(1), channels = self.channels, rate = self.bitrate, output = True, ) self._queue = [] def __enter__(self): return self def __exit__(self, exc_type,

I am writing a program in Python on RaspberryPi, But I am getting an error ImportError No module named pyaudio After that I tried git clone http://people.csail.mit.edu/hubert/git/pyaudio.git but again get another fatal: destination path 'pyaudio' already exists and is not an empty directory. Can you please guide me that how do I install PyAudio in RaspberryPi Remove the directory PyAudio which already presen in /home/pi and then try these steps sudo apt-get install git sudo git clone http://people.csail.mit.edu/hubert/git/pyaudio.git sudo apt-get install libportaudio0 libportaudio2

I'm doing a project on Signal Processing in python. So far I've had a little succes with the nonblocking mode, but it gave a considerable amount of delay and clipping to the output. I want to implement a simple real-time audio filter using Pyaudio and Scipy.Signal, but in the callback function provided in the pyaudio example when I want to read the in_data I can't process it. Tried converting it in various ways but with no success. Here's a code I want to achieve(read data from mic, filter, and output ASAP): import pyaudio import time import numpy as np import scipy.signal as signal WIDTH = 2
