A sound field is defined by several QSpatialAudioSoundSource - objects that define a sound at a specified location in 3D space. You can also - add stereo overlays using QSpatialAudioStereoSource. - - You can use QSpatialAudioListener to define the position of the person listening - to the sound field relative to the sound sources. Sound sources will be less audible - if the listener is further away from source. They will also get mapped to the corresponding - loudspeakers depending on the direction between listener and source. - - QSpatialAudioEngine offers two output modes. The first mode renders the sound field to a set of - speakers, either a stereo speaker pair or a surround configuration. The second mode provides - an immersive 3D sound experience when using headphones. - - Perception of sound localization is driven mainly by two factors. The first factor is timing - differences of the sound waves between left and right ear. The second factor comes from various - ways how sounds coming from different direcations create different types of reflections from our - ears and heads. See https://en.wikipedia.org/wiki/Sound_localization for more details. - - The spatial audio engine emulates those timing differences and reflections through - Head related transfer functions (HRTF, see - https://en.wikipedia.org/wiki/Head-related_transfer_function). The functions used emulates those - effects for an average persons ears and head. It provides a good and immersive 3D sound localization - experience for most persons when using headphones. - - The engine is rather versatile allowing you to define amd emulate room properties and reverb settings emulating - different types of rooms. - - Sound sources can also be occluded dampening the sound coming from those sources. - -*/ - -/*! - Constructs a spatial audio engine with \a parent. - - The engine will operate with a sample rate given by \a sampleRate. Sound content that is - not provided at that sample rate will automatically get resampled to \a sampleRate when - being processed by the engine.
