In order to do this, uncomment the line with the key word SamplingRate and put in a value of 22050. A solution is to reduce the amount data to be processed by changing the sampling rate in the file scope.ini or reduce the number of bits per sample. In this case the program will react slowly. The CPU load on a slow computer (less than 1GHz) can go up to 100%, especially in the frequency analysis mode. If such jumps are observed, the input signal should be attenuated Program reacts very slowly With some sound cards, however, this leads to an overflow and instead of a large positive value, a large negative value is sent, which leads to a complete distortion of the signal. In this case the maximum possible value should actually be recorded by the soundcard. Strange jumps in the signalĪ large signal can exceed the maximal allowed input voltage. Check the audio mixer and enable the appropriate device. AUDIBLE ASKS TO INSTALL AUDIBLE MANAGER AGAIN GENERATORIn order that the generator signal is audible on the speaker, the appropriate equipment has to activated. AUDIBLE ASKS TO INSTALL AUDIBLE MANAGER AGAIN DRIVERIn this case you might need a special driver like Virtual Audio Cable. Some soundcards do not allow to select an internal source as a recording device. If the signal generator is used and a channel is switched on, the input device selected in the audio mixer has to be the Stereo Mixer (somtimes called Wave Device). No signal on the oscilloscopeĬheck for the correct selection of the input device in the control panel. You might have to kill the LabView process from the task manager. Here only terminating and re-starting the program helps! AUDIBLE ASKS TO INSTALL AUDIBLE MANAGER AGAIN WINDOWSUnfortunately it sometimes happens that communication with Windows breaks down. The oscilloscope shows no signal and the display is frozen If your device dows not show up, you need to change the data format in scope.ini to match the format of the device. Only devices which support the selected data format (sampling rate and bits per sample) are actually listed. My sound card does not show up in the device list In Windows Vista/7 enable the Stereo Mix or Wave Device (not available for all soundcard cards) in order to avoid the above problems. If no input device is enabled, the program will complain about it and terminate immediately. In this case you have to check, that at least one input device is enabled in the sound settings (green check mark). This is the default behaviour under Windows Vista/Win7. Some soundcards recognize if speakers or a microphone is installed. No soundcard is found - special problem with Windows Vista/7Ĭheck in the hardware manager, that Windows actually has a soundcard correctly installed. Contact the author in order to obtain a resale license. AUDIBLE ASKS TO INSTALL AUDIBLE MANAGER AGAIN LICENSENo license is required, but if you like to support the further development of the program you might consider obtaining a private donation license.Īny commercial application requires a corresponding license.ĭistribution and sale of the program is prohibited. AUDIBLE ASKS TO INSTALL AUDIBLE MANAGER AGAIN SOFTWAREThe use of the software and of the documentation is granted free of charge for private and non-commercial use in educational institutions. In order to get the program running, uninstall the Run-Time engine (Control panel › Add/Remove Program › National Instruments ) prior to a re-install of this software. The error message, that the installed LabView Run-Time engine (version 7.1) is incompatible with the required one (version 7.1.1), is caused by a previously installed LabView Run-Time engine. An error message is shown when starting the program Delete the folder in order to reset to the files in the installation directory of the scope. Only changes in this file and directory are actually recognized by the program. The file can be found in the directory C:\Users\ \Appdata\Roaming\scope. Since version 1.42 the configuration is stored in the file settings.ini (used to be scope.ini). Try to uninstall the previous version of the Scope and the LabView Run-Time engine (entry in the list of programs under National Instruments). The program will not install on older versions of Windows! The Soundcard Scope requires one of the following Windows operating systems: 2000, XP, Vista, 7, 8 or 10.
