On my old laptop Spectrum Lab ran smoothly down the screen. On my new laptop it stops about every second and then catches up. I'm using the same config.ini on both machines. What am I doing wrong? New machine runs a lot faster on everything else.

It seems like the issue you are facing with Spectrum Lab on your new laptop is related to the hardware or configuration settings of your new machine. Since it runs smoothly on your old laptop, it is possible that there may be some compatibility issues or settings that need to be adjusted on your new laptop. You might want to check if there are any specific requirements or recommendations provided by the Spectrum Lab software for optimal performance on different machines. Additionally, you may also consider reaching out to the Spectrum Lab support team for further assistance in resolving the jerky behavior issue.

Dear Reader,


My DELL Vostro15/3000 laptop (from 2015, W 10) has only a headphone- and a VGA15-connector (besides USB's) to put digital data in to reach SpecLab via the soundcard.
Pinout checking suggests me that VGA-pin 11 (E-DDC) and -pin 5 or 10 (Ground ) could work ... or is USB-data-connection a better option ?


Thanks for your answer in advance !


Best regards,


Onno Lotgering.

I don't think that's possible to convert a mono MP3 to stereo MP3 in Spectrum Lab. I've searched or this application and found out that it can only analyze the frequency and spectrum, but nothing on the conversion part.


You can use other application for this operation. For example, install Audacity, load the track, then go to Edit > Duplicate. From the arrow next to Audio Track, select Left Track, and for the next one select Right Track, then go back to first layer, click the arrow again and choose Make Stereo Track. Save the file and you now have a Stereo track.


Note: You might need LAME MP3 in order to save as MP3. Download: http://lame.buanzo.org/
