Sound¶

We represent sounds as a list of SoundSample objects.

Example Usage¶

# Create a Sound object called 'sound' with 256 samples.
sound = Sound(256)

# Find its length. This will be 256.
length = sound.getLength()

# Load a sound from a file.
otherSound = Sound('media/always.wav')

# Play it.
otherSound.play()

# Open it in the interactive sound explorer.
otherSound.explore()

# Get its samples.
samples = otherSound.getSamples()

# Print the first sample's value.
samp = samples[0]
print(samp.getValue())

Initialization¶

To initialize a silent sound with a given number n of samples:

Sound.Sound(self, n)¶

Parameters:	n (int) – number of samples long the sound will be.

To initialize from a file:

Sound.Sound(self, filename)

Parameters:	filename (string) – the filename of the sound file.

# Loads the sound 'always.wav' that lives in the 'media' folder.
s = Sound('media/always.wav')

Methods¶

Play the sound.

Sound.play(self)¶

sound.play()

See a visual representation of the sound in the interactive sound explorer.

Sound.explore(self)¶

sound.explore()

Write your sound to a wav file.

Sound.write(self, filename)¶

Parameters:	filename (string) – filename for the written file.

sound.write('mysound.wav')

Getters¶

Return the length of a sound.

Sound.getLength(self)¶

length = sound.getLength()

Return the list of samples.

Sound.getSamples(self)¶

samples = sound.getSamples()

Return the sample at index.

Sound.getSample(self, index)¶

Parameters:	index (int) – the index of the desired sample.

aSample = sound.getSample(0)

samples = sound.getSamples()
anotherSample = samples[0]

# This will print True.
print(aSample.getValue() == anotherSample.getValue())
