摘要： In a method and system for audio level detection and control, an amplitude of an audio signal may be compared to a threshold and an attenuation applied to the audio signal may be adjusted based on the comparison. In instances that the amplitude of the audio signal is greater than or equal to the threshold the adjustment may comprise increasing a first attenuation factor until the amplitude of the audio signal is less than the threshold. The first attenuation factor may be subsequently decreased until the amplitude of the audio signal is greater than or equal to the threshold or until the first attenuation factor is equal to zero. The attenuation of the audio signal may be controlled via a digital gain circuit within the hardware audio CODEC, wherein an overall attenuation factor of the digital gain circuit is a sum of the first attenuation factor and a second attenuation factor.

摘要： Aspects of a method and system for digital gain control in an audio CODEC are provided. In this regard, in a hardware audio CODEC, a plurality of gain values in decibel format may be generated and may be summed to generate an overall gain value in decibels. Gain values may be ramped over a plurality of audio samples. The overall gain value in decibels may then be utilized to scale one or more audio signals. A first portion of the overall gain value in decibels may be converted to a scalar and a remaining portion of the overall gain value in decibels may be converted to a shift count. Accordingly, the scaling may comprise multiplying one or more audio signals by the scalar to generate one or more scaled audio signals and shifting the scaled audio signals by a number of bits equal to the shift count.

摘要： A central audio hub, comprising an audio switch, a bus matrix, and an audio buffer, is triggered to read audio samples of an audio stream from the audio buffer. The central audio hub routes the audio samples via the bus matrix to one or more surrounding audio modules such as an audio codec and an audio interface communicatively coupled to the central audio hub. The audio stream may be directly from an external application processor or from an external DDR. With the audio stream from the DDR, a DMA controller may fetch the audio samples from the DDR in response to a request received from the audio buffer, and store the fetched audio samples into the audio buffer for routing. The audio switch may be triggered at a determined sampling rate to read the audio samples from the audio buffer utilizing a determined sample format, and to route the audio samples to the surrounding audio modules.
