* Add Tap Tempo Feature (#6375) Resolves #5181 * Update formatting, use namespaces, etc. * Use Qt Designer .ui file to handle the UI Thanks to irrenhaus for the idea Also added a few buttons I will add functionality for * Play metronome sound when tapped * Improve stabilization speed by comparing differences in length between intervals To improve the speed at which the BPM counter stabilizes at a certain number, we now compare the differences in length between the last two taps and the most recent two taps and reset the counter if the threshold is passed. I made it so that a difference of 500 ms resets the counter. * Remove duplicate m_ui An artifact from my battle with Git and merge conflicts.. * Format TapTempoUi header file * Add lmms namespace in UI file * Remove taptempo.ui XML file Not needed * Add LMMS_EXPORT to SamplePlayHandle * Use std::chrono::duration<double, std::milli> for intervals Co-authored-by: irrenhaus3 <irrenhaus3@gmail.com> * Use alias for steady_clock Co-authored-by: irrenhaus3 <irrenhaus3@gmail.com> * Speed up convergence by accounting for recent intervals This uses a combination of keeping track of a more accurate BPM, while also using a BPM difference threshold to move towards the true BPM more quickly. After three taps, a "recent interval" is calculated, which is similar to the latest interval, but less fluctuating since it accounts for three taps instead of one. This allows for comparing between the BPM on the display with the recent BPM more closely. We then compare the difference in magnitude of both BPM's with the threshold. If the threshold is passed, the counter gets reset. * Remove semicolon from "QOBJECT;" in plugins/TapTempo/TapTempo.h Co-authored-by: Hyunjin Song <tteu.ingog@gmail.com> * Add newline between using alias and constructor * Cleanup header files * Add // namespace lmms::gui comment * Rename header guards in plugins/TapTempo/TapTempo.h Co-authored-by: Dalton Messmer <33463986+messmerd@users.noreply.github.com> * Rename header guards in plugins/TapTempo/TapTempo.h Co-authored-by: Dalton Messmer <33463986+messmerd@users.noreply.github.com> * Rename header guards in plugins/TapTempo/TapTempoUi.h Will merge this file with ``TapTempoView`` soon.
