MXL 900 condenser mic and Acid Pro 6 - recording playback offbeat

Posted on

Member Since: Feb 22, 2010

I have just finally upgraded my recording set up. I bought the MXL 900 condenser mic and I am using it with Acid Pro 6.

The problem that I am encountering is this: when I record my vocals to a beat my words do not register at the same time in the software as when I am saying them, so when I end record the vocals are not lined up with the beat. Not only that but it sounds like they are playing back faster, or at least at a different pace. Do I have to configure any specific setting in Acid to use this mic properly? Does it have anything to do with the fact that the mic records on a 24 bit / 96 KHz sample rate?

Your help and advice will be much appreciated.

Sounds like the buffers are set too high, hard to tell without a list of gear you are using. Is your soundcard a built in/consumer or do you have an interface. Either way, definitely sounds like buffers/latency.

Also, on 24/96... unless you are recording for BluRay (88.1) I would leave it at 24/44.1 for export to CD (16/44.1), might as well record for what your target as the only thing you will do is downsample later.

My soundcard is the original one that came with the computer, I think its SigmaTel.

What can I do to fix this buffer/latency issue, will I need to purchase a new sound card? If so do you have any recommendations?

You need an interface (dedicated soundcard) for recording music ideally. You can get by though as some do it everyday.

I think first I would try downloading the ASIO4ALL driver, to my knowledge it let's your Sigma Tel be treated as an ASIO card and can help reduce latency.

There is an area in windows volume mixer that lets you adjust buffers as well but I'm not sure if it's the same for all.

Other than that, try recording in a project at 24/44.1, there is no need to go higher and it really will stress a soundcard/system once you get a few tracks rolling.

Thanks a lot for the help man. I am downloading the ASIO driver right now.

I also would upgrade to Acid pro 7. I had 6 for a while, and even though it is a solid DAWS, Sony really kicked it up a few notches with Acid Pro 7. I just got the latest update 7e for it, and have had ZERO issues with it. Fantastic cheaper DAWS.

Well, if he's using an MXL990 without an interface, then he must be using the USB version of that mic because a stock sound card wouldn't provide the phantom power the MXL 990 would need to function properly.

So would ASIO4ALL have any impact on a USB mic's performance? I'm not so sure it would.

Make sure that you have the virtual preamp software installed, just in case that provides any sort of performance improvement. At least it gives you one more gain stage (volume fader) to use:

That same page has a manual that has some helpful info in it as well.

Well if that's the case, then it should treat it as it's own interface if using ASIO. Sooo... if using the sigmatel with Acid and able to capture vocal takes Acid must be running in WDM mode.

Other option, he may have a cheap phantom power adapter in line somewhere.

On ASIO4ALL, I don't know if it would impact performance really but I assume it would work as the driver. Although if he has the USB version then it's a moot point as it would already support ASIO on it's own.

What exactly are you using?
