The reason for moving the implementation out from CSoundGenerator into its own class is, because CSoundGenerator was a very complex and obscure class. It mixed many tasks in one place. CSelcalPlayer is designed to play SELCALs only. The following design changes have been made, compared to CSoundGenerator: * Use pull mode instead of push mode. QBuffer is used as the QIODevice and is a wrapper around QByteArray. Therefore it is not necessary to implement our own QIODevice. * Internally it uses a CThreadedSelcalPlayer to relieve the load of the main thread. CThreadedSelcalPlayer inherits CContinuousWorker, no low level QThread implementation was necessary. * Push mode was not implemented. * It is important that the QAudioOutput is allocated in the worker thread. QAudioOutput allocates internal objects, which cannot be moved to the worker thread. * Data caching. The generated seclal audio data is cached. refs #736
