Audio feedback (also known as acoustic feedback, simply as feedback) is a positive feedback situation that may occur when an acoustic path exists between an audio input (for example, a microphone or guitar pickup) and an audio output (for example, a loudspeaker ). In this example, a signal received by the microphone is amplified and passed out of the loudspeaker. The sound from the loudspeaker ...
Signal separation. Source separation, blind signal separation ( BSS) or blind source separation, is the separation of a set of source signals from a set of mixed signals, without the aid of information (or with very little information) about the source signals or the mixing process. It is most commonly applied in digital signal processing and ...
Social media can help to improve an individual's sense of connectedness with others and be an effective communication (or marketing) tool for corporations, entrepreneurs, non-profit organizations, advocacy groups, political parties, and governments. Social movements use social media for communicating and organizing.
Digital image processing. Digital image processing is the use of a digital computer to process digital images through an algorithm. [1] [2] As a subcategory or field of digital signal processing, digital image processing has many advantages over analog image processing. It allows a much wider range of algorithms to be applied to the input data ...
The study, therefore, claims that Broca's area is the "motor center for speech", which assembles and decodes speech sounds in the same way it interprets body language and gestures.
Auditory illusion. Auditory illusions are false perceptions of a real sound or outside stimulus. [1] These false perceptions are the equivalent of an optical illusion: the listener hears either sounds which are not present in the stimulus, or sounds that should not be possible given the circumstance on how they were created. [2]
A spectrogram is a visual representation of the spectrum of frequencies of a signal as it varies with time. When applied to an audio signal, spectrograms are sometimes called sonographs, voiceprints, or voicegrams. When the data are represented in a 3D plot they may be called waterfall displays .
The audio-lingual method or Army Method is a method used in teaching foreign languages. It is based on behaviorist theory, which postulates that certain traits of living things, and in this case humans, could be trained through a system of reinforcement. The correct use of a trait would receive positive feedback while incorrect use of that ...
