The TPA5050 accepts a single serial audio input, buffers the data for a selectable period of time, and outputs the delayed audio data on a single serial output. One device allows delay of up to 170 ms/ch (fs = 48 kHz) to synchronize the audio stream to the video stream in systems with complex video processing algorithms. If more delay is needed, the devices can be connected in series. https://elecena.pl/product/30557492/stereo-digital-audio-delay-processor-with-i2c-control-rsa-16-40-to-85 2026-08-02 https://elecena.pl/product/30557492/stereo-digital-audio-delay-processor-with-i2c-control-rsa-16-40-to-85 2026-11-06
