To change general application settings, applicable to all windows, you can use the Application settings dialog available from the menu option "File/Application settings dialog…":


Check online for a new software version after each start: If this option is selected, SIGVIEW will search online for a new version each time it is started. You can turn the option off if it is slowing down the start-up process or you are not interested in new versions.


Use first text row from CSV/ASCII file as window title if possible: If SIGVIEW determines that the first column of the CSV/ASCII file is suitable, it will use it to generate title text for each channel window. If you do not want this, you can turn this option off.

Always use first CSV/ASCII column as sampling rate if possible (don't ask): If SIGVIEW determines that the first column of the CSV/ASCII file is suitable to calculate a sampling rate of the signal, it will ask the user if they want to use it. Turn this option on if you want to omit the question and use this information automatically without asking.

Presume decimal comma instead of decimal dot when pasting CSV/ASCII data from clipboard: If using the option to paste CSV/ASCII data from clipboard, SIGVIEW presumes decimal dot format by default (e.g. 183.44). If your data displays a decimal comma (e.g. 183,44), turn this option on.

Save display settings into a custom chunk in WAV file: Use this setting to specify if SIGVIEW should store its custom parameter into a custom chunk in a standard WAV file. Should be turned off only if you have an older program which has problems opening WAV files saved from SIGVIEW. See File Formats for details.

Use WAV file creation date/time as signal time: This option determines if SIGVIEW will use WAV file creation time as signal time (only for WAV files which do not contain SIGVIEW custom data chunk)


Color scheme: Choose color scheme for displaying all windows. White and Black schemes are currently available.

Spectrogram frequency axis direction: Choose the direction of the frequency axis (Y-axis) in spectrogram windows.

Font size for all displays: You can the general font size factor for all windows. This affects, for example axis labels, instrument values, status bar etc. You will have to restart SIGVIEW in order to apply new font settings.

Display signal cursor simultaneously in all related windows: If you turn this option on, a Signal ruler (mouse cursor) will be displayed in all other signals related to the active window (its children, parents, synchronized windows) on the same position, if they use the same units and value range on their X-axes.

Use Log X/Y-Axis display as default for all spectral windows: By using these two options, you can determine if Log X/Y axis will be used for all new spectrum windows. Axis properties can, of course, be changed later for each window separately by using its context menu.

Show color map by default in all 3D graphics: Turn this option on if you want to see a color map on all new 3D/Spectrogram windows. You can also turn color map displaying on or off for each window by using its context menu.

High DPI-resolution settings (restart needed): By using these two buttons, you can set how should SIGVIEW appear on screens with High-DPI settings (high resolution in relation to screen size). After clicking on a button to make your selection, you will have to restart SIGVIEW to apply the setting. "No adjustments" means that SIGVIEW will appear on screen in its native resolution. This will result in a crisp display, but icons and text may be too small. "Adjust automatically" will adapt SIGVIEW appearance to the current resolution. It will solve the problem with icon or text sizes, but may result in a blurry UI elements.

Signal playback

Play signals as fast as possible instead of simulating real-time speed: If you would like to process signal as fast as possible when using the signal playback function, turn this option or the corresponding toolbar button (graphic) on. Otherwise, SIGVIEW will replay the signal by using real-time speed. This option works globally, i.e. will be applied to all signals after you change it in the main menu.

Adjust volume automatically for audio playback: If you try to play the signal and there is no sound, maybe the signal amplitude is simply not high enough. SIGVIEW expects signal amplitude values in a 16-bit range, i.e. -32767…32767. If you would like SIGVIEW to automatically adjust signal volume before playing, you can turn this option on.

Audio playback in loop: If you would like SIGVIEW to start playing a signal from the beginning when one of playback options reaches the end of the signal, turn this option on. Alternatively, you can also use the corresponding toolbar button (graphic).

Use this Audio device for playback: You can select the audio device to be used for audio playback. The "Default" setting will use the default audio output device in your operating system.
