When I import a 44.1 kHz WAV file into a 48 kHz project, the file produces clicks throughout. Initially, I couldn’t identify the cause until I changed the sample rate of the file to match the project, which resolved the issue. The same audio file works fine when imported into Cubase and converted there.
Could you look into this issue please? I also believe there should be a warning window that warns the user about the mismatch and asks what actions to be taken, just like in Cubase.
yes and not. Actually VSTLive is way much practical with this. It does an on-the-fly sample rate conversion to the AudioInterfaceSampleRate. Last time the mixing desk knew only 96k and VL3 just went smoothly. Also a few of my audio tracks are 44.1kHz and VL 2,3 all playing them correctly. What version you use?
You can always choose not to show the warning window again.
I’m using 3.0.13.
but there is no reason for notifying, or. You shouldn’t know anything about if the computer can do the on-the-fly-samplerate-conversion, no?
In my case the warning would have been helpful because I was not aware of the sample rate mismatch at first. Had I known it would have been easier and faster to identify.
Here is the audio file for your reference. You can hear constant clicks in VSTL audio. I’ve also attached Cubase audio for comparison.
VSTL:
Cubase:
just asking: what is the audio format? WAV 44.1 or MP3 44.1?
and is the audio-interface is set to 48k?
What audio-interface, what driver?
Maybe with your details, developers can reproduce the phenomeon and look for possible fixes.
The audio is 44.1 kHz WAV. The audio interface is Axe-Fx III, USB version 1.17, and is set to 48 kHz.
Do you think, you can upload the orig 44.1k file here?
I can try it to you on my computer and also developers can try on their computers too.
could you please revise the link, it asks for this and that regarding icloud.
I’ve updated the link. Try this one now.
hmm, no a single crackle here with your file. Could you check if your CPU has enough “time” for processing?
The clicks happen only at the outro part where the guitar solo is for some reason. This is the same part that I posted here earlier. So did you check that part?
I tried 2048 buffer size and the project only had the audio file. So my CPU is not the issue.
oh, okay, let’s try 128 as sample-buffer (or 256 samples).
oh, unfortunately at the guitar OUTRO I can hear some slight pops. You’re right, that eliminates as switching audio-interface to 44.1kHz
The Axe-Fx III is at a fixed sample rate of 48 kHz and it can’t be changed. I solved the problem by converting the audio file to 48 kHz in WaveLab. But still this a bug that needs to be reported.
I’ve just tried another audio file for a different track that also has a different sample rate from the project. The same exact issue happened. The thing is, the clicks are audible only in quite parts as they get lost in loud parts. The track I tried this time is very dynamic, and the cracks were clearly audible throughout the whole track.
could you pls senbd us such an audio file (PM), that would be helpful, thanks.
Thanks for the files.
While we thought we’d heard something, it was more of the “crunchy attacks” of the guitar solo at the end (nice music btw).
We then played back the file and recorded via the main recording function (at 48 kHz) and imported this and the original into Cubase 15 (at 48k). There, Cubase applied sample rate conversion and then we applied phase-inversion to one channel. This exposes the differences. While there are small residuals (to be expected), those were almost beyond recognition. However there are some “micro-crackles” which result from the different approaches to samplerate conversion, we’ll check if we can improve there.
If that differs from your results and if you want to, you could do the same in VST Live, play back and record a part of the file which should expose the artifacts (make sure to have all faders at 0dB and no inserts etc), then send that file to us for eamining, thanks.
These crackles become more noticeable in other tracks where there are quiet parts. I’ve included another audio file in the last PM where you can hear the crackles clearly throughout the whole track. I’ve also tested other tracks with dynamic parts, and the crackles were very clear there as well. I can provide those tracks too if needed. These crackles would be amplified on a PA system, which would make the problem worse in a live setting.
Thank you!
