The captured multi-microphone audio signals are corrupted by acoustic background noise as well as by echoic signals that significantly degrade the intelligibility of the desired signal, and restrict the performance of subsequent audio processing systems.
This reference design demonstrates dual microphones for audio input via stereo ADC, low-power DSP performing noise reduction, acoustic echo cancellation, and other audio quality enhancement algorithms.
This design also features TI’s Smart Amp technology for high-quality and high-SPL audio output from a micro-speaker.
