If you think about this "aliasing" as in, what occurs in 3d graphics, then you can understand this. What these 3d fiters do is either remove infirmation with blur (FXAA) or use information that is not available in the image (MSAA and derivatives)
In audio recording, sampling at 88k would be like generating MSAA x2 image, so it can be displayed with higer fidelity, despite the outgut resolution being in lower 44k sampling rate.
- saltcured 3y agoAliasing can actually occur in the capture stage if the setup isn't right. Think of moire patterns in a video with highly textured subjects. It can happen whenever a signal is sampled. The mastering discussed higher up in the thread is going on ahead of time at the studio, not on your playback system. The whole mastering pipeline starts with some initial capture resolution from microphones/cameras. The studio processes these original raw captures into a combined form and prepares the distribution format, i.e. a planned audio/video stream resolution. The studio can use different resolutions during capture, processing, and final distribution. Generally speaking, the highest rates would be easiest to work with and avoid perceptible artifacts. But practical tradeoffs are made to save cost whether in processing, transfer, or storage.
