1. Play the sameple music or upload an audio file.
2. Press PLAY to begin the sequence.
3. Change settings in real-time. Notice how the sound degrades as you lower the sampling rate and sample size.

Observe: Sampling rate is the "shutter speed" of audio. Lowering the rate means the computer takes fewer snapshots per second. This causes Aliasing—high frequencies move too fast to be measured, making the audio sound muffled or underwater.
Observe: Sample size (Bit Depth) determines the precision of each volume measurement. A 2-bit sample has only 4 levels," forcing the computer to round volume levels inaccurately. This creates Quantization Error, heard as fuzzy static or background noise.
