Helos Bonos Posted May 4, 2020 Share Posted May 4, 2020 I think this might be related to my latency issue. Or my audio drop out issue. Or maybe everything is related. I don't know if it's even Cakewalk, my computer, or my MOTU audio interface. When I record audio (my horrible singing) there is a crunchy glitch that shows up in pretty much the same spots on my timeline. I've always thought it was just the crunchiness that comes with recording at too low of a buffer size (64) trying to avoid latency. But it seems to be embedded in the audio clip. It's at the same spot even if I move the clip up or down the timeline. And the noise is there with or without effects. I tried bouncing a short selection to mp3 to no avail. Once I got an error message, the second try, I it bounced to a silent mp3 file. So I ended up recording it from my Voice recording app built in to Windows 10 in m4a format. I'm attaching it here.

MediaGary Posted May 4, 2020 Share Posted May 4, 2020 Okay, I'll make a try at understanding the root of the problem: A good place to start is to run LatencyMon [www.resplendence.com] to check that your machine happy with its combination of video card, network (wired/wireless) and other driver interactions.

bitflipper Posted May 4, 2020 Share Posted May 4, 2020 This doesn't sound like any noise I've heard that's caused by the interface or buffer settings. It sounds more like an intermittent analog connection, e.g. a broken mic cable, or a mic that's had an internal mounting point broken. I've had that happen twice: once after tipping over a mic stand holding a ribbon mic, and after dropping an SM-58 onto concrete (yes, you can hammer nails with those things, but they're not indestructible if you set your mind to it). Does this noise go away if you increase buffer sizes? Note that MOTU interfaces do support zero-latency monitoring, meaning you don't need to set your buffers to extremely small values while tracking vocals. My interface stays at 2048 samples all the time, whether I'm tracking or mixing. Link to comment Share on other sites More sharing options...
Helos Bonos Posted May 4, 2020 Author Share Posted May 4, 2020 @MediaGary Someone else also suggested that Latency Monitor program on another post of mine for a different (related?) problem. I forgot I actually have it on my PC. I'll run it and see if I can get some clues. @bitflipper This seems to be a new problem. I havne't touched the mic or any cables. Actually, I have maxed out the buffer size to 1024 and still hear it in places. I don't think this is a coincidence but I notice the noise at transitions of my song. Chorus to verse to example. Right around the transition. Here's anothing thing I noticed by accident: I opened up my preferences to check on my buffer size, didn't change anything (buffer at 64), hit Ok. Now the latency is gone (5.6ms at least). But after a few seconds, it creeps back. So I'm still getting latency even at a 64 buffer. And here is another problem that I'm sure is related but I was going to do a separate post on it. And this is not a CbB issue. I've had this problem for a long time even with Reaper: The audio will go silent (during playback or recording) and there will be a high pitch "peep" sound around 10k for a second or two, then resume playing or recording. This has been plaguing me for a very long time and I've not been able to figure it but I'm sure all my latency, audio dropouts and this glitch noise are all interrelated. There has to be one culprit causing all of this. I need to get it figured out soon as I'll be tracking a client when this quarantine thing cools down.

bitflipper Posted May 4, 2020 Share Posted May 4, 2020 If you're running on a laptop, make sure to disable your wi-fi adapter. Latency mon is a must. Be sure to let it run for a while so that it's gathering statistics while you get the noise. Link to comment Share on other sites More sharing options...
Jon White Posted May 4, 2020 Share Posted May 4, 2020 Somewhat lightheartedly I mused that it sounds like a "trial mode" reminder on a plugin or something. Link to comment Share on other sites More sharing options...

Robert Bone Posted May 5, 2020 Share Posted May 5, 2020 Some plugins do generate a bit of noise, when they are in some demo mode or unauthorized - some Windows Updates can cause some plugins to decide they are not running on an authorized system, even though that very same system WAS fine - it depends on how those plugins determine they are on a new machine or not, and those methods for coming up with a secret formula that they rely on, can interpret the computer has changed, when really it was just some Windows Updates that were applied. I have had this happen to me in the past. Bob Bone Link to comment Share on other sites More sharing options...
John Vere Posted May 5, 2020 Share Posted May 5, 2020 Latency should not matter as Dave has said, My system I keep at a medium buffer always and I have zero latency because I'm monitoring at the interface and not at the back end. All systems will have latency and the best of them get things pretty low but this is only needed for using things like guitar sims. 99% of modern set ups will never screw up at a medium buffer, Too high or too low they might. The best way to trouble shoot problems is to strip things down to bare bones. Record your vocals to a project with just a 2 track audio backing track. Nothing else added. If the glitch is still there then it's not a software issue. Then to test hardware you have to swap out each component until you find what is broken. This might require you to use another audio interface you borrow. Link to comment Share on other sites More sharing options...
Helos Bonos Posted May 5, 2020 Author Share Posted May 5, 2020 @MediaGary @bitflipper Thank you guys for reminding me about LatencyMon. I ran it and I'm sure it will point me to the direction to solve all my problems. Problem is, I'm not that great with computer stuff so I don't quite understand everything in the results. I'll paste the text here and hopefully you can decipher it for me. FYI, I was not doing music during this monitor. Not sure how big a difference that makes. If you want I can do it again while recording. But I think this shows that I have an existing problem recording or not since the interrupt and DPC routine meters are maxed out to the red. But maybe it's from running for almost 2 hours? Anyway, thanks. _________________________________________________________________________________________________________ CONCLUSION _________________________________________________________________________________________________________ Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. At least one detected problem appears to be network related. In case you are using a WLAN adapter, try disabling it to get better results. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.

I am no expert by any stretch, but just for experimenting I would disable the network card to see if it does any difference. I would also disable the HDMI audio driver. 1 Link to comment Share on other sites More sharing options...

Disable variable speed settings like Intel Speed Step and AMD Cool N Quiet in the BIOS setup for more accurate results. First I'd make sure your power settings are set to "High Performance". I normally edit this plan and make sure nothing is set to go to sleep, e.g. USB, drives, screen etc, and make sure the CPU is set to 100% all the time.

msmcleod Posted May 7, 2020 Share Posted May 7, 2020 You should also make sure your running the correct drivers for your motherboard. For example, the network card / ATAPI drivers are showing high usage - this could be down to your PC using the Microsoft generic drivers rather than the Intel ones. You can download the drivers for your motherboard here (note there's no Win 10 drivers, but Win 8.1 drivers should work ok)https://support.hp.com/gb-en/drivers/selfservice/hp-compaq-elite-8300-small-form-factor-pc/5232852 Link to comment Share on other sites More sharing options...

However, I did disable "Turbo Mode" in BIOS. I tried recording new vocals and the glitch noise keep appearing in the same spots. Crazy thing is when I listen back, the crackle varies in intensity. Sometimes you can barely hear it, sometimes, it's a big drop out. But when I bounce the clip, a crackle gets baked in. I think there is something wrong with this project not so much CbB. Here is a screenshot of my performance. Link to comment Share on other sites More sharing options...
