A 3d Ambisonic Based Binaural Sound Reproduction System
نویسندگان
چکیده
A computationally efficient 3D real time rendering engine for binaural sound reproduction via headphones is presented. Binaural sound reproduction requires to filter the virtual sound source signals with head related transfer functions (HRTFs). To improve humans localization capabilities head tracking as well as room simulation have to be incorporated. This yields the problem of high-quality, time-varying interpolation between different HRTFs. To overcome this problem a virtual ambisonic approach is used that results in a bank of time-invariant HRTF filter.

متن کاملObjective Localisation Measures in Ambisonic Surround- sound
When designing sound spatialisation systems, localisation accuracy is of great importance, i.e. how well the reproduction of the sound source corresponds to the original recording particularly with respect to source positioning. Ambisonic surround-sound is one such spatialisation system. In this work the two major psychoacoustic mechanisms Interaural Time Difference (ITD) and Interaural Level D...
متن کاملLocalisation of Elevated Sources in Higher-Order Ambisonics
Increasing the order of ambisonic reproduction allows 3D sound fields to be reconstructed with improved resolution and enhanced localisation, at the expense of higher channel counts, increased broadcast bandwidth, and increased storage requirements. Due to the resolution of human hearing it is possible that lowerorder reproduction is sufficient for elevated sources in comparison to sources loca...
متن کاملMultichannel Sound Event Detection Using 3D Convolutional Neural Networks for Learning Inter-channel Features
In this paper, we propose a stacked convolutional and recurrent neural network (CRNN) with a 3D convolutional neural network (CNN) in the first layer for the multichannel sound event detection (SED) task. The 3D CNN enables the network to simultaneously learn the interand intra-channel features from the input multichannel audio. In order to evaluate the proposed method, multichannel audio datas...
