delay ([see my article on delay here](https://github.com/JDSherbert/Audio-Delay)) between two identical signals to create a perception of localization or spaciousness in sound. It's a psychoacoustic phenomenon where the human ear perceives the direction of a sound source based on the first arriving wavefront, and the delayed sound is fused with the original, creating a perception of a single sound source.\n\nIn the Haas effect, you have two identical signals, typically a direct signal (the original sound) and a delayed signal. The delayed signal is introduced with a very short delay, usually in the range of 1 to 40 milliseconds. This delay is short enough that the ear perceives the two signals as a single sound source. By panning the original and delayed signals differently in the stereo field, you can create a sense of spatiality or width in the sound. For example, if the original signal is panned center and the delayed signal is panned slightly to one side, it can create a sense of the sound coming from that direction.\n\nThe Haas effect is often used in audio production for widening the stereo image without creating a noticeable echo. It's particularly useful for creating a sense of spaciousness in vocals, guitars, and other mono sources.\n\nHere's a really good article from iZotope explaining the Haas effect further, with examples:\nhttps://www.izotope.com/en/learn/5-ways-to-adjust-phase-after-recording.htmlI\n\n![image](https://github.com/JDSherbert/Audio-Haas-Effect/assets/43964243/afbaf0b1-29b9-411b-8ce3-6400b7bdde89)\n\n\n-----------------------------------------------------------------------\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjdsherbert%2Faudio-haas-effect","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fjdsherbert%2Faudio-haas-effect","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjdsherbert%2Faudio-haas-effect/lists"}
