An Efficient Hrtf Model for 3-d Sound
نویسندگان
چکیده
A simple model is presented for synthesizing binaural sound from a monaural source. The model produces vertical as well as horizontal and externalization effects. The simplicity of the model permits efficient implementation, allowing for realtime multisource operation. Additionally, the parameters in the model can be adjusted to fit a particular individual's characteristics.

Review of Digital Filter Design and Implementation Methods for 3-D Sound
In this paper, we discuss methods for digital filter design with application to 3-D sound. A review of existing filter design methods for binaural and transaural processing is presented. New methods that take into account the nonuniform frequency resolution of the human ear are explored. Listening tests have been performed to determine the subjective preference of different designs. 0 INTRODUCT...
متن کاملHead-related transfer function interpolation in azimuth, elevation, and distance.
Although distance-dependent head-related transfer function (HRTF) databases provide interesting possibilities, e.g., for rendering virtual sounds in the near-field, there is a lack of algorithms and tools to make use of them. Here, a framework is proposed for interpolating HRTF measurements in 3-D (i.e., azimuth, elevation, and distance) using tetrahedral interpolation with barycentric weights....
متن کاملIndividualized Head-Related Transfer Functions: Efficient Modeling and Estimation from Small Sets of Spatial Samples
This dissertation develops and evaluates a novel way of modeling and estimating individualized head-related transfer functions (HRTFs) from a priori information and a limited number of acoustic measurements. Head-related transfer functions represent and describe the acoustic transformations caused by interactions of sound with a listener’s head, shoulders, and outer ears which give a sound its ...
متن کاملFast head-related transfer function measurement via reciprocity.
An efficient method for head-related transfer function (HRTF) measurement is presented. By applying the acoustical principle of reciprocity, one can swap the speaker and the microphone positions in the traditional (direct) HRTF measurement setup, that is, insert a microspeaker into the subject's ear and position several microphones around the subject, enabling simultaneous HRTF acquisition at a...
متن کامل3-d Sound Image Localization by Interaural Differences and the Median Plane Hrtf
A new 3-D localization method by simulating interaural differences and the HRTF in a sagittal plane is proposed. This method is based on the supposition that the spectral cues would be common in any sagittal plane. Localization tests were performed to examine the method. The results infer that a sound image of any directions can be localized using the HRTF in the median plane and interaural dif...
