Audio

Classes and Methods

cogpy.Audio()

Collection of useful methods for the production of audio stimuli.

file( path )

Plays the .wav file at the specified path.

noise( duration=0.5 )

Generates a sample of white noise of the specified duration (in seconds).

speech( text )

Uses Steel TTS text-to-speech wrappers to generate speech from the given text.

Can use either Microsoft Speech API 5.x, NS Speech Synthesizer, eSpeak, or FreeTTS for speech generation.

system( type="bell" )

Plays the system sound of the underlying OS specified by type.

Currently the only system sound supported is "bell" or "warning".

tone( type="sine", frequency=1700, duration=0.5 )

Generates a tone sound and plays it to the computer's audio player.

type can be any of: "sine", "saw", "tri", or "square".

frequency is specified in Hz.

duration is specified in seconds.

Example Usage

import cogpy

class Test(cogpy.Experiment):
    audio = cogpy.Audio()

    def start(self):
        audio.tone("saw",900)
        yield 1
        audio.speech("Hello world!")
        yield 1
        audio.file("~/music.wav")

exp = Test()
exp.run()
