> These are all techniques that are in wide use in consumer microspeaker systems in tablets and phones, though sadly not common on laptops from most non-Apple brands. Dell / Realtek / MaxxAudio (not sure who to attribute it to) offers such an implementation with mixed results. Some people go to great lengths to remove it and replace with something that offers a flat response -- personally, I didn't mind the alterations it introduced and the speakers "feel" quieter without it installed.

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.

  These are very similar things to the features the MaxxAudio control panel offered (and now that I think of it, my ancient Windows 8 tablet had Dolby-badged software on it with a similar feature set): - Custom response curves for the built-in speaker as well as some brand speakers/headphones (responsible for the "what did you just plug in?" dialog that annoys many users) - User-adjustable EQ - Compression, limiter, AVL, "night mode", loudness: I'm lumping these together in one basket as I don't know what components were in use behind the scenes - Reverb: for cases where you want to listen to music that comes out of a PVC drain pipe of a concert hall's restroom - Possibly downmixing multi-channel audio for headphone users, but I'm not sure in this one either.

    It's similar but to a different degree. The goal is a neutral profile.
