Warning
Recorded audio was lost at the labeled locations. Possible causes: Other applications are competing with Audacity for processor time You are saving directly to a slow external storage device.
I’ve quit other applications with no success. Audacity is saving to Desktop computer.
And if you are recording at a high sample rate, try lowering it to 44.1kHz or 48kHz.
Some people get results by temporarily turning-off their virus protection or Wi-Fi.
Your operating system is ALWAYS multitasking and interrupting, even if you are only running one application. That’s why there are buffers that allow the audio to flow smoothly in-and-out.
And… the other application,/process/driver doesn’t have to be hogging a lot of total CPU time… It only has to hog it for a few milliseconds too long and you get buffer overflow (recording) or buffer underflow (playback) and a glitch in your audio.
The only downside to a bigger buffer is (usually) more latency (delay), which makes it difficult to perform when monitoring yourself through headphones with a delay. (100ms is long enough to notice and be a problem.)
Otherwise there is (usually) no downside to a bigger buffer. (Sometimes there are unexpected-unexplained results and a bigger buffer makes things worse.)
(Latency compensation is only used to automatically sync a recording with a backing track and you need to compensate for the recording and playback latencies.)
