示例1: finalise

void AnalyserBeats::finalise(TrackPointer tio) {
    if (m_pVamp == NULL) {
        return;
    }

    // Call End() here, because the number of total samples may have been
    // estimated incorrectly.
    bool success = m_pVamp->End();
    qDebug() << "Beat Calculation" << (success ? "complete" : "failed");

    QVector<double> beats = m_pVamp->GetInitFramesVector();
    delete m_pVamp;
    m_pVamp = NULL;

    if (beats.isEmpty()) {
        qDebug() << "Could not detect beat positions from Vamp.";
        return;
    }

    QHash<QString, QString> extraVersionInfo = getExtraVersionInfo(
        m_pluginId, m_bPreferencesFastAnalysis);
    BeatsPointer pBeats = BeatFactory::makePreferredBeats(
        tio, beats, extraVersionInfo,
        m_bPreferencesFixedTempo, m_bPreferencesOffsetCorrection,
        m_iSampleRate, m_iTotalSamples,
        m_iMinBpm, m_iMaxBpm);

    BeatsPointer pCurrentBeats = tio->getBeats();

    // If the track has no beats object then set our newly generated one
    // regardless of beat lock.
    if (!pCurrentBeats) {
        tio->setBeats(pBeats);
        return;
    }

    // If the track received the beat lock while we were analyzing it then we
    // abort setting it.
    if (tio->hasBpmLock()) {
        qDebug() << "Track was BPM-locked as we were analysing it. Aborting analysis.";
        return;

    // If the user prefers to replace old beatgrids with newly generated ones or
    // the old beatgrid has 0-bpm then we replace it.
    bool zeroCurrentBpm = pCurrentBeats->getBpm() == 0.0f;
    if (m_bPreferencesReanalyzeOldBpm || zeroCurrentBpm) {

        }
        tio->setBeats(pBeats);
        return;
    }

    // If we got here then the user doesn't want to replace the beatgrid but
    // since the first beat is zero we'll apply the offset we just detected.
    double currentFirstBeat = pCurrentBeats->findNextBeat(0);
    double newFirstBeat = pBeats->findNextBeat(0);
    if (currentFirstBeat == 0.0 && newFirstBeat > 0) {
        pCurrentBeats->translate(newFirstBeat);
    }
