JACK Latency tests [Linux-Sound]
https://wiki.linuxaudio.org/wiki/jack_latency_tests
jack_delay is an utility developed by Linux DSP guru Fons Adriaensen to measure the roundtrip latency of a closed loop audio chain. jack_delay works by emitting some rather annoying tones, capturing them again after a roundtrip through the whole chain and measuring the difference in phase so it can estimate with great accuracy how long has the whole process …

I believe you should at first ensure that you are running a Linux kernel which actually allows you to achieve low typical latency. There are several kernel compile-time configuration options which you might look into: CONFIG_HZ_1000; CONFIG_IRQ_FORCED_THREADING; CONFIG_PREEMPT; CONFIG_PREEMPT_RT_FULL …
Latency compensation and xrun reduction tips [Linux …
https://wiki.linuxaudio.org/wiki/latency
Compensating for loopback latency. Although latency mostly refers to buffer size which delays immediate feedback of input, there is additional latency due to the basic processing of your audio interface. There is no way to reduce this “loopback” latency, but its existence will affect the timing of recorded overdubs.
Raspberry Pi and realtime, low-latency audio [Linux-Sound]
https://wiki.linuxaudio.org/wiki/raspberrypi
By default USB soundcards (or actually the snd-usb-audio kernel module) gets index -2 so it will never end up as the default soundcard. If you want your USB audio interface to be the default soundcard look up the following line in /etc/modprobe.d/alsa-base.conf: options snd-usb-audio index=-2. And either comment it: #options snd-usb-audio index=-2

Audio Latency Consequences on applications: Music: critical issue Communications: larger latencies can be tolerated but still have to be limited (Android specifies continuous output latency < 45 ms, continuous input latency < 50 ms) Audio/Video playback: larger latencies can be tolerated as long as synchronization is maintained

What OS has the lowest audio latency? - Linux, macOS …
https://linustechtips.com/topic/1156826-what-os-has-the-lowest-audio-latency/
I've used it in the past for like, personal home audio recording and it's work really well. It's probably as close to competitive as Linux gets in this space without doing like, an Arch install with that low-latency kernel or something completely custom like mentioned before.
JACK user docs - Linux Audio
http://linux-audio.com/jack/
It allows for much lower latency performance internal to the soundcard/device.-R means realtime. This allows you to take full advantage of the low latency patches for the Linux kernel. You should enable this if you are doing master recordings or want to ensure the applications will receive the audio stream as quickly as possible.-P means Priority. This is superfluous to the -R flag but …
Noob’s Guide to Linux Audio: ALSA, OSS, and Pulse Audio ...
https://linuxhint.com/guide_linux_audio/
PulseAudio isn’t the only sound server for Linux. There’s also JACK, which is a recursive acronym for JACK Audio Connection Kit. Whereas PulseAudio was developed with the needs of general Linux users in mind, JACK is intended for DJs and audio professionals, providing real-time, low-latency connections for both audio and MIDI data.
