Adding native Voicemeeter intergration - #29

src/UI/mainwindow.cpp:161

• The UI allows selecting update intervals as low as 20ms, but the implementation refreshes ChatMix by synchronously spawning HeadsetControl (waitForFinished()), which is unlikely to be safe/necessary at that frequency. Consider raising the minimum to match the runtime clamp.

    voicemeeterIntervalSpinBox = new QSpinBox(connectionGroup);
    voicemeeterIntervalSpinBox->setRange(20, 1000);
    voicemeeterIntervalSpinBox->setSuffix(tr(" ms"));
    voicemeeterIntervalSpinBox->setValue(settings.voicemeeterUpdateIntervalMs);

src/Utils/voicemeetercontroller.h:8

• QStringList is used in the class interface (dllCandidates() return type) but the header doesn't include <QStringList>, which can cause a compile error depending on include order.

#include "settings.h"

#include <QLibrary>
#include <QString>

src/Utils/voicemeetercontroller.cpp:113

• This qDebug() runs for every mapping on every timer tick, which can spam logs and impact performance at low update intervals. Consider gating it behind QT_DEBUG (or a logging category).

        const long result = m_setParameterFloat(parameter.data(), gain);
        qDebug() << "Voicemeeter ChatMix" << chatmix << parameter << gain << "result" << result;

src/DataTypes/settings.h:69

• Defaulting to a 50ms update interval causes frequent synchronous HeadsetControl process executions (via API.updateChatMix()), which can lead to high CPU usage and UI stutter. A higher default is safer for most systems.

    bool voicemeeterInvert = false;
    int voicemeeterUpdateIntervalMs = 50;
    int voicemeeterDeadband = 0;
    QString voicemeeterActiveProfile = "Game / Chat";

src/UI/mainwindow.cpp:121

• updateVoicemeeterChatMix() calls API.updateChatMix(), which blocks on QProcess::waitForFinished(). Allowing a 20ms timer interval can create near-continuous blocking work on the UI thread. Consider clamping the minimum interval higher (or making the chatmix refresh async).

This issue also appears on line 158 of the same file.

    voicemeeterController.configure(settings);
    timerVoicemeeter->stop();
    if (settings.voicemeeterEnabled)
        timerVoicemeeter->start(qBound(20, settings.voicemeeterUpdateIntervalMs, 1000));
}

src/Utils/voicemeetercontroller.cpp:47

• If a candidate DLL exists but fails to load (e.g., missing dependencies / wrong architecture), the current error message says the DLL "was not found", which is misleading. Track whether a file was found and include QLibrary::errorString() when load fails.

    if (m_loggedIn) return true;
    for (const QString &candidate : dllCandidates()) {
        if (!QFileInfo::exists(candidate)) continue;
        m_library.setFileName(candidate);
        if (m_library.load()) break;
    }
    if (!m_library.isLoaded()) {
        m_lastError = "VoicemeeterRemote64.dll was not found. Install Voicemeeter or copy the DLL beside the application.";
        return false;
    }
