DESCRIPTION
Digital effects, noise reduction, speech clarity and Ambient Noise Cancellation (ANC) algorithms are all supported, suitable for a wide variety of mobile and handheld devices. Acoustic Echo Cancellation (AEC) algorithms are also supported. The WM5100 digital core provides extensive capability for programmable signal processing algorithms. Equalisation and application-specific filters can be implemented, including digital effects to improve audibility and stereo imaging in small size loudspeakers. Highly flexible digital mixing, including multi-channel sample rate conversion between asynchronous clocking domains, provides usecase flexibility across a broad range of system architectures. Three independent digital audio interfaces are provided, each supporting a wide range of standard audio sample rates. The integrated headphone drivers provide 3 stereo groundreferenced outputs. These can also be configured in mono differential (BTL) configuration. Noise levels as low as 3.2μVRMS provide hi-fi quality output.
