Directional audio coding - perception-based reproduction of spatial sound
نویسندگان
چکیده
Directional Audio Coding (DirAC) is a perceptually motivated technique for spatial audio processing. DirAC analyzes in short time windows the sound spectrum together with direction and diffuseness in frequency bands of human hearing, and uses this information in synthesis. It has applications in capturing, coding and resynthesis of spatial sound, in teleconferencing, in directional filtering, and in virtual auditory environments.

Perceptual Spatial - Audio Coding
A novel technique for the perceptual coding of spatial audio is presented. This coding technique allows individualized 3D audio presentation and exploits the dichotomous roles of the lowfrequency interaural timing and level difference cues versus the high-frequency spectral cues in human sound localization. The high-frequency spectral cues are modified to match the acoustics of the listener’s o...
متن کاملApplications of Directional Audio Coding in Audio
Directional Audio Coding (DirAC) is a method for spatial sound representation, applicable to different sound reproduction systems. In the analysis part, the diffuseness and direction of arrival of sound is estimated in a single location depending on time and frequency. In the synthesis part, microphone signals are first divided into non-diffuse and diffuse parts, and are then reproduced using d...

متن کاملBroadband analysis and synthesis for Directional Audio Coding using A-format input signals
Directional Audio Coding (DirAC) is a parametric non-linear technique for spatial sound recording and reproduction, with flexibility in terms of loudspeaker reproduction setups. In the general 3-dimensional case, DirAC utilizes as input B-format signals, traditionally derived from the signals of a regular tetrahedral first-order microphone array, termed A-format. For high-quality rendering, the...
متن کاملRendering of virtual sound sources with arbitrary directivity in higher order Ambisonics
Higher order Ambisonics (HOA) is a spatial audio reproduction technique aiming at physically synthesizing a desired sound field. It is based on the expansion of sound fields into orthogonal basis functions (spatial harmonics). In this paper we present an approach to the two-dimensional reproduction of virtual sound sources at arbitrary positions having arbitrary radiation directivities. The app...
