Tasks when performing or inserting a new measurement from file

determines if a message box should pop up asking the user if the previous measurement is to be saved when performing or inserting a new measurement.

determines if the unplotted measurements should be kept in memory or not. If you are to perform several hundred measurements, you should be aware of that it might fill up the memory if they are not removed. Measurements are deleted by using File->Delete Unplotted Measurements, alternatively Delete unplotted measurements from memory will delete all measurements as long as they are not set as active or plotted. This prevents the memory to run full. It is useful if a repeated measurement is to be done and each measurement is never supposed to be stored. E.g. when calibrating a sound system, repeated measurements are needed but the results are not to be kept in memory. To sum up, this option deletes the previous unplotted measurements from memory after a new measurement has been performed and plotted.

determines if plotting is to be performed when a measurement is performed or inserted.

determines if the data in the active plot is to be saved after a measurement is performed or inserted. The filename of the text file depends on if the measurement has a file name or not. If the measurement does not have a filename, it is saved under the default folder given in Measurement->Defaults for Saving. The filename is “PlotMeasFromMem<Measurement number>.txt”. If the measurement has a filename, it is saved using the measurement filename but with the extension .txt.

This is useful for batch-processing, e.g. if you want to compute the smoothed magnitude frequency response of several measurement files and send the data to a text files. This is done automatically by using File->Insert, then mark the measurements files you want to process and insert them.

determines if room acoustics parameters are to be displayed and/or saved after a measurement is performed or inserted. The setting telling if it is displayed or saved to file or both is found in the bottom of the Room Acoustics->Calculation Options… dialog box.

The Send to Text file option is useful for calculating the room acoustics parameters of several files and saving the results in one operation. First check this option, then make sure Send to Text-file is checked in Room Acoustics->Calculation Options…. In File->Insert, select all the files that you want to process. If the measurement has a filename, it is saved using the measurement filename(s) but with the extension .txt. The filename of the text file depends on if the measurement has a file name or not. If the measurement does not have a filename, it is saved under the default folder given in Measurement->Defaults for Saving. The filename is “RoomAcMeasFromMem<Measurement number>.txt”.

If this is turned off both channels in a 2-channel measurement are plotted in each plot. If you for example, view the impulse response in the upper plot and the magnitude frequency response in the lower plot, you normally want to do it this way.

If the option is turned on and a 2-channel measurement is performed, channel 1 is plotted in the upper plot and channel 2 is plotted in the lower plot (if the window has two plots). This option is useful if you wish to view two plots having the same plot type. This is done in the room acoustics measurement setup file RoomAcMeasurement. Here the time-data plot type is displayed in both plots. When a two-channel measurement is performed, channel 1 is plotted in the upper plot and channel 2 is plotted in the lower plot. It makes it easy to compute room acoustics parameters that need two impulse responses, a primary and a secondary. The primary impulse response is taken from the upper plot, while the secondary is taken from the lower plot.

This also applies if two measurements are inserted using File->Insert. See the FAQ for more information.
