Abstract: Exemplary embodiments or implementations are disclosed of methods, apparatus, and systems for a volume limiter circuit. A rectifier sub-circuit is configured to rectify at least a portion of an audio signal received from an audio source. A junction field effect transistor (JFET) has a channel connected in series between the audio source and a speaker. A feedback sub-circuit is configured to provide a gate signal at a gate of the JFET and to modulate a control signal in accordance with the audio signal crossing the JFET channel. The feedback sub-circuit is connected with the rectifier sub-circuit so as to extend a range of variable resistance of the JFET channel. The limiter circuit provides functionality that changes in response to varying audio voltages.
