pushkarsingh019 / Single_Channel.py
Last active December 24, 2024 01:58
The function create_single_channel_sound converts a monaural (single-channel) sound into a binaural (two-channel) sound. It places the original sound in either the left or right channel, as specified by the user, and fills the other channel with silence. This is useful for isolating a sound to a specific channel in a stereo format.

This functions take a monoaural sound and returns a single channel sound
Inputs
- sound : the monoaural sound object. The it should be a slab monoaural sound object.

ITD CUES SOUND
def get_angled_sound(angle, sound, externalise, frequency):
"""
This function takes in azimuth angle and monoaural sound and returns sound with the specified angle.
Angle : azimuth angle. Where 0 is the center. So one posituve integer.
Sound : the sound on which you want to get the angled sound.
externalise : Boolean. If the function should externalise sound or not.
frequency : Frequency of the sound to calculate ITD.
head_size : Optional. In case you want calculate ITD specific to head sizes.

Why do humans form categories and concepts?

Reasons for Forming Categories and Concepts

  1. Stimulus Generalization: Humans have a natural tendency to generalize and extend learned behavioral responses to a whole class of stimuli. This allows us to categorize things based on similarities and form concepts to recognize the same experiences again.

  2. Efficiency: Categorizing things into concepts reduces the amount of information that needs to be retained about a whole group of things. Concepts serve as behavioral equivalence classes, allowing us to store general information more efficiently than individual representations.

  3. Natural Groupings: The world of objects and things may have regularities, both physical and functional, that naturally lend themselves to categorization. Humans learn about these regularities and form categories based on existing natural boundaries. This idea dates back to ancient Greek philosopher Plato, who suggested that we "cut nature at its joints" whe
