1. A method comprising:
configuring an audio time and level difference renderer (TLDR) based on one or more received input parameters using a filter parameter model that includes a set of configured binaural dynamic filters, wherein the binaural dynamic filters in the set are coupled via multiple channels for receiving input audio signals that are spilt from a single channel; and
applying the configured audio TLDR to an audio signal to generate spatialized audio content for each channel of the multiple channels,
wherein the generated spatialized audio content is presented via multiple channels to a user.
