A method, comprising: generating, by a processor of an audio system, an audio signal having a volume parameter pausing, by the processor, the audio signal generation at a first time determining, by the processor, whether the volume parameter is set to a first volume level outside of a selected subrange of a full scale volume range at the first time and setting, by the processor, the volume parameter to a second volume level at a second time, wherein the second volume level is different than the first volume level and is based on one or more acoustic factors existing at the second time in response to the first volume level being outside of the selected subrange at the first time and in response to the second time being more than a selected interval after the first time.ġ0. The audio system of claim 1, wherein the second volume level is the same as the first volume level in response to the second time being less than the selected interval after the first time regardless of whether the first volume level is outside of the selected subrange, and wherein the second volume level is different than the first volume level in response to the first volume level being a mute level regardless of whether the second time is more than the selected interval after the first time.ĩ. The audio system of claim 1, wherein the one or more acoustic factors include a time of day.Ĩ. The audio system of claim 5, wherein the one or more acoustic factors include a number of people in the surrounding environment.ħ. The audio system of claim 1, wherein the one or more acoustic factors include an audio decay time of a surrounding environment.Ħ. The audio system of claim 1, wherein the second volume level is based on a time difference between the second time and the selected interval after the first time.ĥ. The audio system of claim 1, wherein the second volume level is within the selected subrange regardless of a time difference between the second time and the first time.Ĥ. The audio system of claim 1, wherein the processor is configured to: pause the audio signal generation at the first time in response to receiving a pause command and resume the audio signal generation at the second time in response to receiving a play command.ģ. An audio system, comprising: a speaker and a processor configured to generate an audio signal having a volume parameter, wherein the processor is configured to: determine whether the volume parameter is set to a first volume level outside of a selected subrange of a full scale volume range when the audio signal generation is paused at a first time, set the volume parameter to a second volume level when the audio signal generation is resumed at a second time, wherein the second volume level is different than the first volume level and is based on one or more acoustic factors existing at the second time in response to the first volume level being outside of the selected subrange at the first time and in response to the second time being more than a selected interval after the first time, and send the audio signal to the speaker for conversion into sound.Ģ. Advances in mediation analysis: A survey and synthesis of new developments. Journal of personality and social psychology, 51(6), 1173. The moderator–mediator variable distinction in social psychological research: Conceptual, strategic, and statistical considerations. However, if they are, for the "required" (or better say "desirable") relationships between IVs and mediator/moderator - see the appropriate methodological literature.ģ. If controls are not part of your mediation/moderation test, then you shouldn't worry much about them. Typically, controls come from literature (or sometimes from common sense. All assumptions of your estimator pertain to your controls in the model (e.g., there should be no multicollinearity between IVs, etc.)Ģ. Let me clarify - two dependent variables - means you have two separate (univariate) models or are you talking about a multivariate model? Now, answering your questions:ġ. Make sure you build on the appropriate literature.
Testing for mediated moderation is quite complex, as it requires both strong theoretical grounds and robust empirical support.
