C++ (Cpp) createIfNeeded Examples

Example #1

File: bandpass.cpp Project: AchimTuran/yse-soundengine

void YSE::DSP::MODULES::bandPassFilter::process(MULTICHANNELBUFFER & buffer) {
  createIfNeeded();
  (*bp).set(parmFrequency, parmQ);

  for (UInt i = 0; i < buffer.size(); i++) {
    buffer[i] = (*bp)(buffer[i]);
  }
}

Example #2

File: playlistmodel.cpp Project: deedos/shotcut

void PlaylistModel::insert(Mlt::Producer* producer, int row)

    createIfNeeded();
    beginInsertRows(QModelIndex(), row, row);
    m_playlist->insert(*producer, row, producer->get_in(), producer->get_out());
    endInsertRows();
    emit modified();
}

Example #3

File: playlistmodel.cpp Project: deedos/shotcut

void PlaylistModel::insertBlank(int frames, int row)
{
    createIfNeeded();
    beginInsertRows(QModelIndex(), row, row);
    m_playlist->insert_blank(row, frames - 1);
    endInsertRows();
    emit modified();
}

Example #4

File: playlistmodel.cpp Project: deedos/shotcut

void PlaylistModel::appendBlank(int frames)
{
    createIfNeeded();
    int count = m_playlist->count();
    beginInsertRows(QModelIndex(), count, count);
    m_playlist->blank(frames - 1);
    endInsertRows();
    emit modified();
}

Example #5

File: playlistmodel.cpp Project: deedos/shotcut

void PlaylistModel::append(Mlt::Producer* producer)
{
    createIfNeeded();
    int count = m_playlist->count();
    beginInsertRows(QModelIndex(), count, count);
    m_playlist->append(*producer, producer->get_in(), producer->get_out());
    endInsertRows();
    emit modified();
}

Example #6

File: highpass.cpp Project: Ajj2/yse-soundengine

void YSE::DSP::MODULES::highPassFilter::process(MULTICHANNELBUFFER & buffer) {
  createIfNeeded();

  if (buffer[0].getLength() != result->getLength()) {
    result->resize(buffer[0].getLength());
  }

  (*hp).setFrequency(parmFrequency);
  (*result) = (*hp)(buffer[0]);
  
  calculateImpact(buffer[0], (*result));
}

  Int delayCount = 1; // the original signal

  // add delays to signal
  if (gain0 > 0) {
