Components
ESP32
At the heart of this project is the ESP32 a potent microcontroller renowned for its compact size, formidable performance, and wireless capabilities. This integral component acts as the "brains" of the system, decoding information from a remote control via its infrared receiver. Upon receiving the code, the ESP32 executes custom-written C++ instructions, transmitting them over a mesh network to govern the various functions of each wireless speaker in the system. This design ensures synchronized control, offering seamless interactions across the network. Moreover, the ESP32 comes equipped with a Bluetooth module, enabling it to receive audio wirelessly from devices like mobile phones. It processes the audio data, packetizes it, and dispatches it across the speaker network, guaranteeing each audio packet is acknowledged by the intended speaker and ensuring synchronized playback.
Adau1701
Acting as the digital audio processor, the ADAU1701 is pivotal in refining and managing the audio signals that course through the system. Its built-in SigmaDSP core empowers the ADAU1701 to undertake real-time audio processing. This feature allows me to modify and optimize the sound output, catering to my distinct preferences. Be it for equalization, dynamics processing, or even advanced audio effects, this chip performs with unparalleled finesse. Its integration signifies that my audio setup isn't merely focused on volume but is dedicated to delivering unmatched fidelity and crystal-clear sound. In essence, the ADAU1701 is the linchpin behind the sound quality, ingesting the audio signal fed by the ESP32 and processing it to ascertain the best possible auditory experience.
