Working Principle

The ZL38052LDF1 audio processor consists of an ARM9 processor and various embedded audio DSPs and audio algorithms. The processor is a single-chip solution that combines a baseband processor with advanced audio functions. The processor is designed for advanced audio applications, delivering high audio performance in a small package. The advanced audio algorithms embedded in the processor include noise reduction, echo cancellation, and acoustic echo control.

The processor provides two audio I/O interfaces, a digital audio interface and an analog line-level audio input. The digital audio interface supports 24-bit resolution and a sample rate of up to 48kHz. The analog line-level audio input provides analog stereo signal consisting of left and right channels. The signal is converted to digital signal with a microphone pre-amplifier for processing. The processor can process signals from multiple microphones and provide noise reduction, echo cancellation and acoustic echo control.

The processor can be used to control audio processing functions including dynamic range compression, equalization, dynamic range expansion, tone control, bass and treble adjustment, as well as limiting and noise gate control. The processor also provides various algorithms for audio mixing, reverberation, delay and reverb. The processor can be used to process multiple audio tracks and control audio playback from multiple sources.
