To people making fun - this is not about creating audio files, but rather about techniques to reduce latency and jitter when playing audio files. Similar to the crazy techniques that the VR folks like Carmack have proposed. Yes, indeed, audio files these days have WAY more information content them the human ear can distinguish, but if your playback has skips and assorted corruption that doesn't matter.

For example, one of the responses proposed pre-loading a large fully-rendered audio segment onto a DMA buffer to remove the CPU from the latency-sensitive pipeline entirely.
