Unveiling the Secrets of Stereo Imaging and Time Alignment

It discusses how humans perceive stereo sound, emphasizing the role of time arrival differences and the Head Related Transfer Function (HRTF). Time Alignment basically means the sound from all of the speaker drivers arriving at the listener’s ears at the proper time to perceive the sound correctly.

Practical implications for audio setups are highlighted, stressing the need for time-alignment between channels for optimal spatial resolution. The article concludes by advising caution in using time delay features and emphasizes the significance of speaker placement for optimal audio reproduction.
