1. A non-transitory computer readable medium comprising instructions stored therein that configure a computer to:
present an application programming interface, API, wherein the API comprises a user-specified sound level parameter;
receive, via the API, one or more values for the user-specified sound level parameter that are associated with a digital audio asset; and
incorporate code into a simulated reality application that is being composed, wherein the code determines a loudness correction gain or contribution for the digital audio asset based on the one or more values of the user-specified sound level parameter by determining a difference between i) the one or more values of the user-specified sound level parameter and ii) a playback hardware device parameter that represents a known or predefined sound level producible by a playback hardware device in which the simulated reality application is running, wherein the loudness correction gain compensates for the difference, and the loudness correction gain is to then be applied to the digital audio asset during run time of the simulated reality application.
