HANMUS F10K

This product is designed for audio applications, featuring hardware floating-point processing capability, and supports master/slave I2S interfaces, multiple UART interfaces, and 4-channel ADC interfaces. To accommodate different customer requirements, it supports external AUDIO ADC/DAC chips, allowing customers to select audio codecs of varying quality based on end-use needs, and implements the 48kHz/24-bit high-quality audio sampling standard to enhance sound detail and fidelity. Equipped with master/slave I2S interfaces, the slave interface adaptively supports sampling frequencies ranging from 44.1kHz to 48kHz, facilitating seamless integration into customers' audio systems — such as digital speakers, digital mixing consoles, and karaoke jukeboxes. Any device with an I2S audio interface can interface directly with this product and leverage its professional effects algorithms. The product incorporates a 3-stage pitch-shifting algorithm that delivers a simple and easy-to-use live feedback suppression effect, making it ideal for building straightforward KTV systems for mass production. Using a multi-layer early reflection model combined with a discrete and varied comb filter structure, it simulates a full, multi-layered, richly textured virtual stereo reverb model. It also supports individualized adjustment of diffusion and density parameters to reproduce as natural a reverberation effect as possible. The product provides an independent ECHO structure for both left and right channels, each with its own independent pre-delay, to create as immersive a KTV surround experience as possible. Additionally, the product offers a 24dB/octave microphone high-pass filter and a 7-band input equalizer, enabling more professional compatibility with microphones of varying characteristics for an optimized microphone audio source.
