playback - How to vary PortAudio latency? - Stack Overflow
https://stackoverflow.com/questions/70644964/how-to-vary-portaudio-latency
The real-time latency of the playback and/or recording, in a portaudio-based app, is defined by the value framesPerBuffer that is received in the callback function renderaudio (). But you don't modify the value of this variable within this renderaudio () callback function. Instead, you have the option to set the number of frames per buffer ...
Portaudio: Bindings for the Portaudio portable sound library
https://docs.racket-lang.org/portaudio/index.html
My observations suggest that this API is limited; it can open only a small number of simultaneous streams, and the latency for playing sounds is extremely high. The WASAPI API (if that’s not redundant) has its own issues; in particular, it seems to be necessary to manually set the playback device to the right sample rate (often 44100Hz) before starting DrRacket.
PortAudio: Blocking Read/Write Functions

PortAudio 2.0. Main Page ... Note that we use the default high latency values to help avoid underruns since we are usually reading and writing audio data from a relatively low priority thread, and there is usually extra buffering required to make blocking I/O work.

PortAudio: Sample rate is 48000 Hz, device output latency is 4.33 ms. PortAudio: Allowed additional buffering latency is 10.00 ms/480 frames.
PortAudio - an Open-Source Cross-Platform Audio API
PortAudio is a free, cross-platform, open-source, audio I/O library. It lets you write simple audio programs in 'C' or C++ that will compile and run on many platforms including Windows, Macintosh OS X, and Unix (OSS/ALSA). It is intended to promote the exchange of audio software between developers on different platforms.
