这个例子对我来说似乎很清楚。您只需将示例另存为playwav.py调用即可：
python playwav.py my_fav_wav.wav
带有一些额外注释的wave示例：
import pyaudioimport waveimport sys# length of data to read.chunk = 1024# validation. If a wave file hasn't been specified, exit.if len(sys.argv) < 2: print "Plays a wave file.nn" + "Usage: %s filename.wav" % sys.argv[0] sys.exit(-1)'''************************************************************************ This is the start of the "minimum needed to read a wave"************************************************************************'''# open the file for reading.wf = wave.open(sys.argv[1], 'rb')# create an audio objectp = pyaudio.PyAudio()# open stream based on the wave object which has been input.stream = p.open(format = p.get_format_from_width(wf.getsampwidth()), channels = wf.getnchannels(), rate = wf.getframerate(), output = True)# read data (based on the chunk size)data = wf.readframes(chunk)# play stream (looping from beginning of file to the end)while data != '': # writing to the stream is what *actually* plays the sound. stream.write(data) data = wf.readframes(chunk)# cleanup stuff.stream.close() p.terminate()
