Can ACID Pro Remove Turntable Rumble?

The subject says it all. Is there a way in ACID Pro to remove turntable rumble from a vinyl recording?

That's a job for plugins. What you'll want to do is run an Equalizer on the track to cut the low-end frequencies, then possibly a Compressor to deal with any volume spikes caused by the rumble. You can try experimenting with the order in which the plugins act to optimize them.

Hello, Welcome

Audio Cleaning Lab

The star of the show is the LP click and crackle recovery, the effectiveness of which is definitely not a matter of opinion. It works well and without unduly affecting high-frequency detail. It’s been possible to do things somewhat like this for a while. Turntable clicks are reasonably detectable as sudden sharp rises in level and techniques for isolating and suppressing them have been around for a while. The filters offered in Cleaning Lab seem well configured with both click and crackle removal and some LP-specific rumble filtering which works particularly nicely on orchestral recordings with quiet passages.

That's awesome. Is Cleanup Lab a feature in Acid Pro? Google Search reveals nothing of use.

No, but you can buy it on Amazon for £12.99 Magix Audio Cleaning Lab. it will improve the reduction in turntable rumble. You could spend time experimenting with acid pro plugins, but Audio Cleaning Lab seems to offer a quicker process.

Thanks everyone for the input! :)

I'll give Magix Audio Cleaning Lab a try for sure. I always thought DAK's DePopper did the best work on clicks and pops, but we're talking about software here so there's always room for improvement. I'll report back....

Thanks for the update, good luck.

Does anyone have an idea as to what specific setting I should try for the rumble? Or, should I just go through all the options?

Magix Audio Cleaning Lab is exactly what the doctor ordered. I ran many tests and the results are outstanding! Thanks to everyone that replied, I am grateful to have that nuisance eliminated! :)

You can also get RX Elements for dirt cheap (usually) and there are VST Plug-Ins of its Cleanup Effects available in ACID Pro after installation...

Okay, this is strange. The rumble has returned. Here's what my process is for getting a vinyl record on to my hard drive. I start by recording the vinyl with Audio Recording Lab. I then use the different tools within the software to clean up the recording. I then run it through ACID Pro for the fine tuning and dB levels, etc. Now, all of a sudden I am at stage 1 again. The rumble is back. I have no idea what I did or didn't do. The level meter in Winamp doesn't pick up the rumble, but it shows in ACID Pro as well as Audacity. I can't hear the rumble, but I see it in those VU level meters dancing around until the music takes over. What the hell did I do? Is there some setting that I screwed up? Even with the max setting, it doesn't work.

Well, I adjusted what is visible on the VU meter in ACID Pro, and that seems to have done the trick. There is no sign of the mystery "rumble" or "hum" or whatever the hell it is. Sounds good in Winamp. Sounds good in MAGIX Audio Cleaning Lab internal player. So, while whatever it is may not be actually "removed", everything looks and sounds like it did before. If anyone has any insight, or a setting I should look into, please let me know.

Hi

. . . . I start by recording the vinyl with Audio Recording Lab. I then use the different tools within the software to clean up the recording. I then run it through ACID Pro for the fine tuning and dB levels, etc. . . .

Are you exporting the cleaned audio to a new file, eg WAV, from ACL, then importing this new exported file into Acid?

If not then how are you 'running it' through Acid ?

I do the cleanup in Cleaning Lab, then save the newly created WAV. I open the newly created WAV in ACID Pro. I do the fine tuning, like adjusting the dB levels, and cleaning the intro and outro of the song if needed. I then render the file as a FLAC file to be put into my music collection after I manually tag and all that stuff.
