在Pepper机械手上录制声音时出错

Question

I want my Pepper robot to record a piece of audio using startMicrophonesRecording() . In NAOqi v2.5 it takes four arguments (path, type, hertz and microphones). Trying to run

AD.startMicrophonesRecording("/data/home/nao/recordings/microphones/test.wav","wav",16000,(0,0,1,0))

I however get the error message

RuntimeError: Arguments types did not match for startMicrophonesRecording (resolved to '(ssi(iiii))'): 
Candidate: 
  startMicrophonesRecording::(s) (1)

It seems that startMicrophonesRecording() only wants one argument. I can see in past versions of the function that it used to only take the file path as an argument, so maybe Python is looking at a past version of NAOqi for the modules?

I have tried setting PYTHONPATH to C:\\Users\\<user>\\<path>\\pynaoqi-python2.7-2.5.5.5-win32-vs2013\\lib using this tutorial , but I still get the same error.

Any ideas as to what I can do?

Python 2.7 on Windows 10.

Answer 1

Did you try with one argument?

The NAOqi v2.5 Link you named, refers to ALAudioRecorder and C++. The "old Version" refers to Python ALAudioDevice . An NAOqi v2.5 Python API for ALAudioDevice is described here .

For me these python snippets works fine:

ALAudioDevice :

import naoqi
from naoqi import ALProxy
AD = ALProxy("ALAudioDevice", "pepper.local", 9559)
AD.startMicrophonesRecording("/data/home/nao/recordings/microphones/test.wav")
AD.stopMicrophonesRecording()

ALAudioRecorder :

import naoqi
from naoqi import ALProxy
AR = ALProxy("ALAudioRecorder", "pepper.local", 9559)
AR.startMicrophonesRecording("/data/home/nao/recordings/microphones/test.wav","wav",16000,[0,0,1,0])
AR.stopMicrophonesRecording()

Answer 2

Your syntax for selecting microphones looks wrong. Use brackets [] instead of parentheses ():

    rec = self.session().service("ALAudioRecorder")
    rec.startMicrophonesRecording(fname, 'wav', 16000, [0,0,1,0])
