what does the terminal show if you run this:
linux/bash:

echo $?

windows/powershell:

echo $LASTEXITCODE

(right after the program ends)

(in the same terminal that it was running from)

if it returns non-zero and the value isn't one of the -1's you return in main, the code itself might give you a hint. if it crashed, those values will tend to correspond to error codes you can search for (sometimes, not always)

I can`t if I press any button console closes

how are you running it?

[terse tapir]

In VisualStudio 2022

oh, if you're already launching it from a debugger you probably just need to make sure all exceptions are enabled to pause the debugger when any are thrown

that will pause the code in place if/where it's crashing

if you type in "exceptions" in the search box at the top of VS2022, you should see an option to open the exception settings

or you can get to it from "Debug" -> "Windows" -> "Exception Settings". just make sure the win32 and c++ exceptions are both checked off. the other ones probably won't get thrown if your application is purely C/C++

the window should look like this, and you can just check off the ones you want the debugger to capture:

if you haven't been using the debugger to trace through the code as it's running, you should also toss a bunch of breakpoints in areas that you think might be causing the problem, then just stepping through things 1 line at a time until you're able to spot what the cause is (if it doesn't end up being a crash)

I can`t it always says about it have no acces to some dll files

[golden socket]

oh, you need to make sure any DLLs that are needed are either in your PATH or just in the same folder as the executable

it has to load those libraries on init of the program to work if your code depends on any additional shared libraries / DLLs

[terse tapir]

what if do not know what is dll filesand where i must search for it? Just it says it about fstream proceses and about portaudio ones

there is how it looks when i start debug run

oh, also it works only one standart 256 samples buffer and ends after this

maybe problem somewhere in my callback function?

[terse tapir]

the problem was a 30-fold discrepancy between the input buffer of sounds and the output buffer
