Hi Psychopy community,
I am trying to record audio responses and calculate voice onset time. I have two plans here:
1 psychopy.sound.Microphone:
mic=Microphone(audioLatencyMode=1,streamBufferSecs=10)
mic_onset=mic.start(when=0,waitForStart=1)
core.wait(5)
mic.stop()
audioClip=mic.getRecording()
audioClip.save(filename)
My question is the mic_onset is the absolute time, how I can accurately calculate the verbal response time?
2 psychopy.voiceKey Recording audio responses and voice onset times
voicekey.pyo_init(rate=44100,buffersize=32)
voice_file_path=generate_filename()
onset_voicekey=voicekey.OnsetVoiceKey(sec=5, file_out=voice_file_path)
onset_voicekey.start()
core.wait(2)
rt=onset_voicekey.event_onset
I have tested the function, the audio file and response time are not accurately detected. Only a few files and response times are created. Is it related to my code or my device? Do I have to use a professional microphone as an input device?
Thank you very muck for your opinions.
