如何将录制的.wav文件保存到Python中的特定目录

Question

我在互联网上找到了一个Python程序，可以使用麦克风直接进行语音录制。但是，当程序完成运行时，程序创建的结果.WAV文件存储在创建Python程序的目录中。那么，如何将录制的文件保存在特定目录中？

import pyaudio
import wave

form_1 = pyaudio.paInt16
chans = 1 # 1 channel
samp_rate = 48000
chunk = 1024
record_secs = 2
dev_index = 2 
wav_output_filename = 'test1.wav' # name of .wav file

audio = pyaudio.PyAudio() # create pyaudio instantiation

# create pyaudio stream
stream = audio.open(format = form_1,rate = samp_rate,channels = chans, \
                    input_device_index = dev_index,input = True, \
                    frames_per_buffer=chunk)
print("recording")
frames = []

# loop through stream and append audio chunks to frame array
for ii in range(0,int((samp_rate/chunk)*record_secs)):
    data = stream.read(chunk)
    frames.append(data)

print("finished recording")

# stop the stream, close it, and terminate the pyaudio instantiation
stream.stop_stream()
stream.close()
audio.terminate()

# save the audio frames as .wav file
wavefile = wave.open(wav_output_filename,'wb')
wavefile.setnchannels(chans)
wavefile.setsampwidth(audio.get_sample_size(form_1))
wavefile.setframerate(samp_rate)
wavefile.writeframes(b''.join(frames))
wavefile.close()

在第10行：

wav_output_filename = '/path/to/specific/directory/test1.wav'
