Tremolo Effect - Digital Audio Processing with STM32 #3 - Phil’s Lab #51

Mixed-signal hardware design course: Real-time digital processing (DSP) of audio data using an STM32 microcontroller in C on custom audio-processing hardware. Third video in series, covering the tremolo effect. Essentially, amplitude modulation of the audio waveform using a low-frequency oscillator (LFO). In this video, we’ll be using a triangular waveform modulator. Including live guitar demo.
