问题 Is it possible to play chords using pyaudio? 回答1: Of course! Just generate the result and pass it to the player. This article covers a method to do it.

问题 My son and I are trying to write a program that will allow a user to input a sequence of musical notes, and save them into a list to be played back. We've come up with the following: import math #import needed modules import pyaudio #sudo apt-get install python-pyaudio def playnote(char): octave = int(char[1]) if char[0] == 'c': frequency = 16.35*octave+1 elif char[0] =='C': frequency = 17.32*octave+1 elif char[0] =='d': frequency = 18.35*octave+1 elif char[0] == 'D': frequency = 19.45*octave

问题 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. This is the error I get when a special character is present: u=self.p.get_device_info_by_index(e) File "C:\Python27\lib\site-packages\pyaudio.py", line 977, in get_device_info_ by_index pa.get_device_info(device_index) File "C:\Python27\lib\site-packages\pyaudio.py", line 987, in _make_device_inf o_dictionary print device_info.name

问题 I'm trying to grab samples from a stream of audio and put them in a shared Queue. I have another process that pulls from this queue.

问题 The following code I tried to run it on Raspberry Pi 3 Model B which has a little big of capacity on it's memory, the problem that I'm facing with the code is that it runs sometimes: from os import environ, path import pyaudio from pocketsphinx.pocketsphinx import * from sphinxbase.sphinxbase import * MODELDIR = "../../../model" DATADIR = "../../../test/data" config = Decoder.default_config() config.set_string('-hmm', path.join(MODELDIR, 'en-us/en-us')) config.set_string('-lm', path.join

问题 I was following the instructions here and I'm having trouble getting the installation to work. Basically, the first part works fine.
