Elevated Speakers Image Correction Using 3-D Audio Processing
A real-time postprocessing technique is proposed to enhance the sound images for playback over elevated loudspeakers for both two loudspeaker and multiple loudspeaker configurations. This is achieved by filter design using either one-third-octave filtering or regularization to prevent sharp peaks in the frequency response. The algorithm was implemented on a TMS320C6201 EVM DSP board, and subjective testing was carried out.:
