【検証】マルチの「デジタルくさい歪み」のノイズはどう消す？オーバーサンプリングの劇的効果を可視化してみた

The "unnatural background noise (aliasing noise)" often heard in high-gain digital sounds. This time, we'll thoroughly examine the effect of "oversampling," which dramatically reduces this noise, using a custom-made tool to verify it visually and aurally!
