There's some confusion at the end of TFA about latency.
What TFA refers to as latency is the time required to inject a MIDI event/message received by RtMIDI into the perl async object - basically inter-thread wakeup. You certainly expect that to be very, very fast - it's what context switching on any multitasking/multithreaded system relies. "Fractions of a millisecond" is in the right ballpark, though on some systems "Tens of microseconds" would be more appropriate as a description.
What "latency" normally means in the context of MIDI or audio is the delay between the user generating a MIDI event somehow and when the audio corresponding to that MIDI event (e.g. a note) is audible. This is typically measured in relatively small numbers of milliseconds (e.g. 1-30).
These are not really connected in any meaningful sense.
- montag 2y agoWhy “TFA” instead of just “the article”? I understand “RTFA”, berating commenters who didn’t “read the fucking article” with a cheeky acronym, but TFA by itself is kind of hostile for no reason. Unless you hated the article that much
- Tepix 2y agoIn my mind, RTFM is read the fucking manual, but TFA is the fine article. It seems to be confusing however, because it's been discussed here previously https://news.ycombinator.com/item?id=29888845 https://news.ycombinator.com/item?id=29888845
- raziel2p 2y agothat's... extremely silly. the confusing thing is why wouldn't you just write "the article"? what's the point of the abbreviation if you don't mean to convey the swear word?
- TylerE 2y agoTA already means something else. 3 characters is lieds than 11. Shrug.
- MonkeyClub 2y ago> TFA is the fine article Isn't it a reference to "the featured article"?
- JodieBenitez 2y agoI thought it was "Read The Fantastic Manual" ;)
