Please adjust the audio levels higher on your videos. I regularly have to turn the volume way up just hear it

[@davidmoss9471]

I cast my videos to my TV and the volume was absolutely fine. Great detailed walk through thank you

[@secretsquirrel9722]

Great info and explanation of the pico's capabilities.
1, It would have been nice to know the actual final cause of the fault.
2, might have also been worth doing a crankcase pressure capture to ensure it was just a top end problem without any contribution from the bottom? So many of these modern engines have failed rings at much lower mileage than expected.
Thank you for sharing. I'm relatively new to this and only have a 4223. Is there an easy way to overlay captures using a common trigger point?

Definitely watching this video later.of late, your audio has been really low. We definitely like and appreciate all the information

[@patrickl6866]

The volume is so low on this video I can barely hear it. I turned on cc so I could understand what was being said

Hi Steve, great piece of information, kindly let us know how you overlay the Microsoft Waveform Overlays on Pico

[@DrivelineMaster]

I found this informative however I have a few questions and agree with Patrickl6866 about the volume. In fact I have found several Pico training videos where I have to turn all my volumes for my speakers up to the maximum just to barely hear the narration. This is not the first time I have commented on the volume. Please ask the author of the video to adjust the volume gain before publishing. Now for my questions. You mentioned the Microsoft Pressure waveform overlay and the pressure overlay software. I'm very interested in this and how it is done. Additionally around time stamp 18:00 you talk about sweat or sweep volume. I couldn't make it out and the closed captions spelled out Sweat Volume. Can you clarify and explain what this is? I hope someone is monitoring comments and can reply.

Swept volume. That is the volume change in the cylinder as the piston moves up or down. At least that is my interpretation.

[@DrivelineMaster]

Thank you.

[@marcosmateo8439]

When watching the video make sure you’re in a setting that is dead silent. The audio is terrible.

[@johnhnetkovsky8917]

would have been a much better video if I could HEAR it

[@weldingjunkie]
