Neumann KU 100 microphone used to record binaural sound. Binaural recording is a method of recording sound that uses two microphones, arranged with the intent to create a 3D stereo sound sensation for the listener of actually being in the room with the performers or instruments.
QSound is essentially a filtering algorithm. It manipulates timing, amplitude, and frequency response to produce a binaural image.Systems like QSound rely on the fact that a sound arriving from one side of the listener will reach one ear before the other and that when it reaches the furthest ear, it is lower in amplitude and spectrally altered due to obstruction by the head.
3-D audio (processing) is the spatial domain convolution of sound waves using head-related transfer functions. It is the phenomenon of transforming sound waves (using head-related transfer function or HRTF filters and cross talk cancellation techniques) to mimic natural sounds waves, which emanate from a point in a 3-D space.
Engineers make a technical distinction between "binaural" and "stereophonic" recording. Of these, binaural recording is analogous to stereoscopic photography. In binaural recording, a pair of microphones is put inside a model of a human head that includes external ears and ear canals; each microphone is where the eardrum would be. The recording ...
Sound localization technology is used in some audio and acoustics fields, such as hearing aids, surveillance [1] and navigation.Existing real-time passive sound localization systems are mainly based on the time-difference-of-arrival approach, limiting sound localization to two-dimensional space, and are not practical in noisy conditions.
Isochronic tones are regular beats of a single tone that are used alongside monaural beats and binaural beats in the process called brainwave entrainment. At its simplest level, an isochronic tone is a tone that is being turned on and off rapidly. They create sharp, distinctive pulses of sound.
Binaural fusion or binaural integration is a cognitive process that involves the combination of different auditory information presented binaurally, or to each ear.In humans, this process is essential in understanding speech in noisy and reverberent environments.
In particular, it has proved an effective way to present spatial audio in Virtual Reality applications (e.g. YouTube 360 Video), as the B-Format scene can be rotated to match the user's head orientation, and then be decoded as binaural stereo.
