The signal path may include an analog signal path portion having an audio input for receiving an analog signal, an audio output for providing an output signal, and a selectable analog gain, and configured to generate the output signal based on the analog signal and in conformity with the selectable analog gain and a digital path portion having a selectable digital gain and configured to receive a digital input signal and convert the digital input signal into the analog signal in conformity with the selectable digital gain. The control circuit may be configured to determine a spectral content of a signal indicative of the output signal and change the selectable digital gain and the selectable analog gain based on the spectral content."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Enhancing dynamic range based on spectral content of signal","description":"In accordance with embodiments of the present disclosure, an apparatus for providing an output signal to an audio transducer may include a signal path and a control circuit.
