The invention provides an
audio signal rendering method, a renderer and a vehicle-mounted audio
system. The
audio signal rendering method comprises the following steps: acquiring a sound
bed signal to be rendered; based on a first
system corresponding to the sound
bed signal to be rendered and a target listening position, determining a conversion relation of the sound
bed signal to be rendered, the conversion relation being used for describing a mapping relation between each
loudspeaker sound channel signal of the first
system and each
loudspeaker sound channel signal of a second system; and converting the sound bed signal to be rendered based on the conversion relation to obtain a sound bed signal corresponding to each
loudspeaker sound channel in the second system. Aiming at the rendering scene of the sound bed signal, the invention provides the rendering method based on audio sound channel conversion, which is suitable for sound bed signal rendering between an audio providing system and an audio playback system under various sound channel layouts, improves the accuracy of sound bed signal rendering, and improves the effect of sound bed rendering.
