Inventors include Bharitkar, Sunil; and Hirvonen, Toni.
The application for the patent was published on June 26, 2026, under issue no. 26/2026.
Abstract: In one embodiment, a method for encoding audio includes accessing a window of the audio that includes audio signals. The method further includes determining, for each of the audio signals, a power of an audio signal relative to a reference audio signal; determining, for each of the audio signals and based on the determined relative power of the audio signal, a gain to apply to the audio signal relative to the reference audio signal, where the gain depends on frequency and on directionality relative to a listener; and encoding the audio so that bandwidth is allocated based on directionality relative to the listener by allocating an amount of bandwidth to each of the audio signals based on the frequency-dependent and directionality-dependent determined gain.
