Visual waveform jitter on track load & start 5.3.2

Hi again,

I’ve noticed a subtle issue in djay that I wanted to bring to your attention. When I load and immediately start a track, the waveform appears visually unstable or slightly jittery for the first couple of seconds. After that, it stabilizes and plays normally.

At this point, I’m not aware of any impact on the sound — at least I haven’t heard anything unusual. But of course, it’s possible there is also a minor audio effect that’s not immediately noticeable. It might be helpful to test this using a steady signal, like a pure tone or beep, to be certain.

Unfortunately, this behavior isn’t very visible in this video I recorded due to framerate limitations, but I’ve attached a recording to help illustrate the issue. In the video, I point out when the problem is happening and when it stops.

Initially, I suspected it might be related to iCloud being enabled (as that setting recently changed on my side), so I tested with iCloud turned off — but the issue still occurs. Based on that, my current conclusion is that this may be related to the latest version (5.3.2.) of djay, as I hadn’t noticed this behavior in earlier versions.

Please let me know if I can provide any additional information.

Thanks for the video and info @DJ_Big_Blender. I’ll share with the team to see what they think.

Hi @DJ_Big_Blender, sorry for the delayed reply. Our engineering team has reviewed your video. It looks like the waveform drawing is slightly jittery until the track is fully analyzed. This is likely a CPU based performance issue due to your older Intel based hardware. We will keep a close eye on this topic to see if other users report similar observations and if so, what hardware they are using.
