Stereo to 5.1 Channel Converter in Max/MSP
This is a max patch for stereo to 5.1 channel convert. Three difference upmixng algorithms (PSD, LMS & ADP) are used, and users can select one of them and compare them. EQ preset is provided so that users can optimize the sound. More details about the algorithms are described as below. The Passive surround Decoder (PSD) The Passive Surround Decoder (PSD) is an early passive version of the Dolby Surround Decoder. The center channel is obtained by adding the original stereo cha

HRTF measurement
What is HRTF? The complex shape of the outer ears leads to many filtering properties that are key to sound localization. Additionally, the head and torso shapes may also lead to spatial cues. These filtering effects are characterized by the head-related transfer function, typically abbreviated HRTF. Often, a generalized one-size-fits-all HRTF is used, as many characteristics of the transfer function are commonly shared amongst all humans. However, individualized HRTFS are mor

Design and Implementation of an Interactive Mixing Environment for VR
The ultimate goal of immersive audio is to completely erase the distinction between simulation and reality by challenging and leveraging knowledge in the fields of acoustics, the physics of sound, and human anatomy. This project was to investigate these ideals by gaining a detailed understanding of current theories and practices in immersive audio and employing that knowledge to create an interactive music experience and tool. The first step in this project was to create a vi
