Python PyAudio库适用于多种开发环境,包括Windows、macOS和Linux操作系统。以下是其相关介绍:

安装步骤

示例代码

以下是一个简单的Python脚本示例,展示了如何使用PyAudio库进行音频录制和播放:

录音示例

import pyaudio
import wave

CHUNK = 1024
FORMAT = pyaudio.paInt16
CHANNELS = 1
RATE = 44100
RECORD_SECONDS = 5
OUTPUT_FILENAME = "output.wav"

p = pyaudio.PyAudio()

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

print("开始录音...")

frames = []

for i in range(0, int(RATE / CHUNK * RECORD_SECONDS))):
    data = stream.read(CHUNK)
    frames.append(data)

print("录音结束!")

stream.stop_stream()
stream.close()
p.terminate()

wf = wave.open(OUTPUT_FILENAME, 'wb')
wf.setnchannels(CHANNELS)
wf.setsampwidth(p.get_sample_size(FORMAT))
wf.setframerate(RATE)
wf.writeframes(b''.join(frames))

wf.close()

播放示例

import pyaudio
import wave

CHUNK = 1024
FORMAT = pyaudio.paInt16
CHANNELS = 1
RATE = 44100
OUTPUT_FILENAME = "output.wav"

p = pyaudio.PyAudio()

stream = p.open(format=p.get_format_from_width(wf.getsampwidth()),
                    channels=wf.getnchannels(),
                    rate=wf.getframerate(),
                    output=True)

data = wf.readframes(CHUNK)

while data:
    stream.write(data)
    data = wf.readframes(CHUNK)

stream.stop_stream()
stream.close()
p.terminate()

通过上述步骤和示例代码,您可以在不同的开发环境中成功使用PyAudio库进行音频处理。
