Listening to the music via headphones using portable media players has become common lately. If the sound is not properly postprocessed by headphone designated algorithm, it is likely to be localized inside the head, making the stereo image unnaturally lateralized between the ears and generally narrow. Common headphone sound enhancing systems can be classified to three categories: simplified spatial processing algorithms, HRTF-based binaural processing algorithms and virtual source positioning… 
Sound image externalization for headphone based real-time 3D audio
This work considers several important factors related to sound propagation, which include image-source model based early reflections with distance decay, wall absorption and air absorption, late reverberation and other dynamic factors like head movement.
Binaural impulse response rendering for immersive audio
This thesis is concerned with the efficient reproduction of immersive and realistic 3D virtual auditory environments. This necessitates the correct virtual reproduction of the soundfield incident at
Signal Processing Framework for Virtual Headphone Listening Tests in a Noisy Environment
A signal processing framework is introduced to enable parallel evaluation of headphones in a virtual listening test. It is otherwise impractical to conduct a blind comparison of several headphones.
Assessment of sound spatialisation algorithms for sonic rendering with headphones
This article first surveys traditional spatialisation approaches intended for loudspeakers, and then reviews them with regard to their adaptability to headphones.
A System-On-Chip Platform for HRTF-Based Realtime Spatial Audio Rendering
A system-on-chip platform for realtime rendering of spatial audio signals is presented and head related transfer functions (HRTF) were sampled in steps of 30◦ for azimuth and elevation.
Fifty Years of Artificial Reverberation
An improved parametric model for a spring reverberation unit is presented, which is currently mainly used for simplified geometries or to generate reverberation impulse responses for use with a convolution method.

The linear prediction residual cepstrum is used to compute the spectral notches with a high degree of accuracy in this work and experiments on reconstruction of the HRIR indicates that the method performs better than other methods.

'Out-of-head' acoustic field enhancement for stereo headphones by embedded DSP
A novel algorithm for enhancing a given 3D acoustic field to the extent of 'out-of-head' has been developed in dedicated fashion for stereo headphones, and thus constructs a variety of listening environments even for headphones without causing listening fatigue.
Spatial sound generation and perception by amplitude panning techniques
The vector base amplitude panning (VBAP) method, which is a reformulation of the existing pair-wise panning method to position virtual sources in arbitrary 2-D or 3-D loudspeaker setups, is introduced.
Spatial sound generation using HRTF created by the use of recursive filters
Generating spatial sound and playing it through headphones is a demanding task, since two important factors, ILD - inter-aural level difference and ITD - inter-aural time difference, need to be taken
A Balanced Stereo Widening Network for Headphones
In order to ensure that only a minimum of spectral colouration is added to the original sound only frequencies below 2kHz are processed, and it makes the stereo widening algorithm well suited for applications to high-quality digital source material.

An out-of-head sound localization system that uses adaptive inverse filtering without any measuring preprocesses is proposed and it is clarified that the proposed method is more effective, in terms of convergence, if the initial value is the average of many listeners' impulse responses.
The methods and results presented in this thesis are applicable to digital audio signal processing in general, and especially to implementation of virtual acoustic environments in multimedia and virtual reality systems.
Embedded implementation of acoustic field enhancement for stereo headphones
Embedded implementation of acoustic field enhancement has been devised dedicatedly for stereo headphones and successfully performs the acoustic signal processing in order to widen an acoustic field generated through stereo headphones with low computational costs.
Localization of Sound from Single and Paired Sources
Three experiments on the localization of air‐borne sound are described. They were conducted in an anechoic room and employed an acoustical “pointer” as the subject's method of indicating the
3-D sound systems: a computationally efficient binaural processor
A low complexity sound processing algorithm based on head-related transfer functions and artificial reverberation is described, which synthesises the binaural recording technique, which allows the reproduction of a complete auditory experience, evoking the sensation of listening to a sound source located at a point in the surrounding space.
Localization of sound in rooms, II: The effects of a single reflecting surface.
It is found that onset cues are of some importance to localization even in free field, and listeners appear to have certain expectations about the reliability and plausibility of various directional cues and perceptually weight the cues accordingly.
