A method for rendering audio data, the method comprising: receiving the audio data including: audio objects comprising audio object signals and associated metadata, wherein the associated metadata includes positional metadata for the audio object signals; and sound field representation data in the form of Higher Order Ambisonic audio data; and receiving playback environment data comprising information as to whether at least one speaker capable of reproducing low-frequency audio signals exists within a speaker playback environment, wherein, if said information indicates that at least one speaker capable of reproducing low-frequency audio signals exists within the playback environment: extracting low-frequency audio signals (925a, 925b, 1042) from the audio data, comprising: applying an object bass extraction process involving low-pass filters to the audio object signals; and applying an HOA bass extraction process involving low-pass filters to a first portion of the HOA audio data; applying a high-pass filter to at least some of the audio object signals to produce a first high-pass filtered audio signal; applying a high-pass filter to a second portion of the HOA audio data to produce a second high-pass filtered audio signal; rendering, after extracting the low-frequency audio signals, the first and second high-pass filtered audio signals into at least one speaker feed signal, based, at least in part, on the playback environment data and the associated metadata, each speaker feed signal corresponding to at least one of the speakers of the playback environment; and performing a bass management process on the extracted low-frequency audio signals, and wherein the bass management process involves routing the low-frequency audio signals to one or more speakers of the at least one speaker capable of reproducing low-frequency audio signals. receiving the audio data including: audio objects comprising audio object signals and associated metadata, wherein the associated metadata includes positional metadata for the audio object signals;
