摘要： A method for automatically controlling loudness of an audio signal to be replayed within a vehicle is provided. The method comprises an automatic loudness measurer measuring a loudness of an incoming audio signal that comprises a sequence of digital audio blocks. Furthermore, a noise level indication signal is received which indicates a noise level within the vehicle and a processor calculates a gain factor based on the measured loudness of the incoming audio signal and the noise level indication signal. If the measured loudness is equal to or above a predefined first target loudness (TLamS), the gain factor is zero. Otherwise, if the noise level indication signal indicates a noise level equal to or above a predefined intermediate noise level, the gain factor is a difference between the measured loudness and a current target loudness, limited to a maximum gain, wherein the maximum gain is a defined absolute maximum gain, and the current target loudness is linearly interpolated, according to the noise level indication signal, between a predefined second target loudness (TLaiS) for the noise level being equal to said intermediate noise level and the predefined first target loudness (TLamS) for the noise level being equal to a predefined maximum noise level. Otherwise, if the noise level indication signal indicates a noise level below the intermediate noise level, the gain is linearly interpolated, according to the noise level, between the gain as defined for the intermediate noise level and zero. Furthermore, the gain factor is applied to the audio signal to be replayed.

摘要： Techniques are described herein that are capable of adaptively modulating audio content based on background noise. For instance, a loudness difference between a loudness of the audio content and a loudness of the background noise is determined. The loudness of the audio content is compared to an upper loudness threshold. A modulation is selected from multiple modulations based on the loudness difference and/or the comparison. Subsequent outputted audio content is modulated using the selected modulation.

摘要： Some implementations involve receiving a content stream that includes audio data, determining a content type corresponding to the content stream and determining, based at least in part on the content type, a noise compensation method. Some examples involve performing the noise compensation method on the audio data to produce noise-compensated audio data, rendering the noise-compensated audio data for reproduction via a set of audio reproduction transducers of the audio environment, to produce rendered audio signals, and providing the rendered audio signals to at least some audio reproduction transducers of the audio environment.

摘要： The present disclosure provides systems and methods for progressively transitioning the playback volume based on a background noise level. The device (800) may have a predetermined quantity of volume levels between a minimum volume and a maximum volume. The volume levels may be spaced by predetermined increments, such that there is a predefined difference between adjacent volume levels. A digital gain (102) may be used to adjust the volume level and an analog gain (106) may allow for the playback volume to be adjusted to an amount between adjacent volume levels. The playback volume may progressively transition within the predefined volume levels by an amount less than the predetermined difference between adjacent volume levels. This smaller amount may be the analog gain (106).
