Run clang-format (the repo's .clang-format: LLVM base, 120 cols, tabs, Allman functions) over every source file so the tree is formatter-clean. Whitespace only -- no behavior change; full x64 + x86 suites pass. Also set SortIncludes: false in .clang-format. Windows include order is load-bearing (windows.h must precede tlhelp32.h / mmreg.h / xinput.h / dinput.h; winsock2.h must precede windows.h), and the default alphabetical sort reorders tlhelp32.h ahead of windows.h -- a build break. Leaving order alone keeps the manual, correct grouping.

// coop_tone: a minimal WASAPI render process that plays a continuous sine wave on the
|
|
// default output endpoint, at a configurable audio format. Used as a known audio source
|
|
// for the audio-mirror tests (a real process actively rendering audio to capture from).
|
|
//
|
|
// coop_tone [seconds] [frequencyHz] [rate] [channels] [bits] [float|pcm]
|
|
//
|
|
// Each trailing arg is optional; an omitted format field uses the device mix format.
|
|
// Default: ~3 s, 440 Hz, device format. Prints "TONE_RENDERING" once audio is flowing so
|
|
// a parent can synchronize before it starts capturing.
