For what it's worth, the article says: ----- Our DSP profiles aim to provide a balanced sound, with the features that people expect from high-quality laptop/small-speaker audio. In particular, we aim for: • A balanced (neutral) tone at moderate listening volumes, with a mostly flat frequency response from a typical listening position • Reasonably high peak volume with acceptable sound degradation (compression, limiting, etc.) • "Fake bass" processing to make audible frequencies that cannot be physically reproduced by the speakers, extending the perceived frequency response of the system. • Equal-loudness volume compensation, so that the sound does not become noticeably tinny as the system master volume is lowered. [...] Our goal is explicitly not to clone the full/exact macOS audio experience. We consider the macOS speaker DSP processing to be too tryhard. ----- So I suspect Asahi's implementation will be far more conservative than the systems you're referencing. It's also worth noting Marcan is a musician.
