  • Publication number: 20190221218
    Abstract: A schematic block diagram of an audio encoder for encoding a multichannel audio signal is shown. The audio encoder includes a linear prediction domain encoder, a frequency domain encoder, and a controller for switching between the linear prediction domain encoder and the frequency domain encoder. The controller is configured such that a portion of the multichannel signal is represented either by an encoded frame of the linear prediction domain encoder or by an encoded frame of the frequency domain encoder. The linear prediction domain encoder includes a downmixer for downmixing the multichannel signal to obtain a downmixed signal. The linear prediction domain encoder further includes a linear prediction domain core encoder for encoding the downmix signal and furthermore, the linear prediction domain encoder includes a first joint multichannel encoder for generating first multichannel information from the multichannel signal.

  • Publication number: 20190168955
    Abstract: A device dilutes an aerosol without distortion due to loss of particles, especially liquid particles, on wall surfaces. An inlet pipe feeds aerosol as inlet aerosol and an outlet pipe has an inlet opening arranged at a finite distance from an outlet end of the inlet pipe. An annular space surrounds an end area of the inlet pipe. A clean gas line opens, via an outlet opening, into the annular space. A process is provided including feeding the aerosol as inlet aerosol through the inlet pipe, with particle-free clean gas fed to an end area of the inlet pipe and mixed with the fed inlet aerosol into a diluted outlet aerosol. The diluted outlet aerosol is sent to a measuring device. The mass flow of the aerosol sent to the measuring device and that of the added clean gas are maintained at a fixed ratio.
