ADC and DAC conversion, sampling, Nyquist theorem, aliasing, bit depth, quantisation, and the complete signal chain.
Guided lessons coming soon
Explore how analogue sound is converted to digital data. Adjust sample rate and bit depth to see how they affect the quality of the digital representation.
Reconstruct the complete audio signal chain from acoustic sound through digital processing and back. Drag components into the correct order to build the path from microphone to speakers.
Visualise how analogue-to-digital conversion works — see sampling, quantisation, and bit depth in action. Explore the relationship between sample rate, bit depth, and audio quality through interactive simulations.
Revision quizzes and flashcards coming soon
