ADAU1701 DSP Easy Start Board (P2P ADAU1401)
ADAU1701/1401 is a complete single-chip audio system with built-in control interfaces for 28 / 56-bit audio DSP, ADC, DAC, and similar microcontrollers. Signal processing technologies including equalization, crossover, bass enhancement, multi-band dynamic processing, delay compensation, speaker compensation, and stereo image widening can be used to make up for the practical limitations of speakers, amplifiers, and listening environments, thereby significantly improving the sound quality experience. This signal processing technology is comparable to that used in high-end studio equipment. Most processing is done in full 56-bit double-precision mode, resulting in excellent low-level signal performance. The ADAU1401 is a fully programmable DSP. With [...]
