[英]Python, Error audio Recording in 16000Hz using Pyaudio
I use Python 2.7.3, Mac OS 10.8.2 and Xcode 4.5.1 我使用Python 2.7.3,Mac OS 10.8.2和Xcode 4.5.1
I am trying to record sound using PyAudio following the instructions in http://people.csail.mit.edu/hubert/pyaudio/ 我试图按照http://people.csail.mit.edu/hubert/pyaudio/中的说明使用PyAudio录制声音
and using the program 并使用该程序
"""PyAudio example: Record a few seconds of audio and save to a WAVE file."""
import pyaudio
import wave
CHUNK = 1024
FORMAT = pyaudio.paInt16
CHANNELS = 2
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")
frames = []
for i in range(0, int(RATE / CHUNK * RECORD_SECONDS)):
data = stream.read(CHUNK)
frames.append(data)
print("* done recording")
stream.stop_stream()
stream.close()
p.terminate()
wf = wave.open(WAVE_OUTPUT_FILENAME, 'wb')
wf.setnchannels(CHANNELS)
wf.setsampwidth(p.get_sample_size(FORMAT))
wf.setframerate(RATE)
wf.writeframes(b''.join(frames))
wf.close()
It works well with RATE = 44100
. 它适用于RATE = 44100
。 But I want to record with RATE = 16000
and CHANNELS = 1
但我想记录RATE = 16000
和CHANNELS = 1
Changing the values give me an error as 更改值会给我一个错误
How will I be able to record with RATE = 16000
? 如何以RATE = 16000
录制?
I experienced the same problem. 我遇到了同样的问题。 The issue was fixed in portaudio, but brew installed an old version for me. 问题已在portaudio中修复,但brew为我安装了旧版本。 I upgraded with 我升级了
brew install portaudio --HEAD
and then was able to run your code with CHANNELS=1 and RATE=16000 然后能够以CHANNELS = 1和RATE = 16000运行您的代码
