Harshness Begone

I've used Rode NT1 mics for three years. They work well for my acoustic guitar but have always resulted in harsh vocal tracks with female vocalists singing fairly loudly at 8" to 24" distance. I auditioned Rode NTV and CADE200 mics to compare. The CAD was no better than the NT1 and The NTV only slightly less harsh. The mics go into a DBX386 and then via s/pdif into a Roland VS1680 (MTP mode).

Over the last three years, my approach was to back the DBX386 input trim (drive) off until no flashing reds occur on the peak LED ("-3db" according to the DBX manual). Then, adjust the DBX output control so the DBX meter frequently illuminates the –4dB yellow meter light, but never high enough to illuminate the 0dB red meter light. I did this on the assumption that it would achieve maximum signal to noise ratio without overloading or distorting.

I then adjusted the VS1680 digital input fader so the 1680 meter ranged between –12dB and –4dB with regular peaks to -4dB and occasional peaks hitting –3dB or –2dB. I kept the levels below or at –4dB vs -1dB, not out of concern for overloading or distortion on the track, but to preserve headroom when later mixing multiple tracks down to master tracks.

This method has resulted in consistently harsh vocals. Initially, I suspected the Rode mics, then the analog inputs of the VS1680, later the DBX386 and finally (and increasingly irrationally) the VS1680 digital recording technology. I know quality recordings frequently have wonderful sounding loud vocals using similar technology. Several queries on the internet and locally made it clear to me that no one else was hearing the intolerable vocal harshness that threatened to torpedo most of my recorded song projects (which sounded fine in all other respects).

Well, in the last week, I finally achieved significant relief from the harshness. The strong-voiced female vocalist is positioned at 9” from the Rode NT1 with a pop screen. I set the DBX output control to the unity gain position. I then adjust the DBX input trim (drive) so the –8dB yellow meter light comes on occasionally. The –4dB yellow meter light never comes on. I set the VS1680 digital input slider to unity gain. The 1680 meter ranges from –16dB to –8 dB with occasional peaks hitting -6dB.The Rode NT1 still sounds a little too bright for my taste and lacks warmth, but the result is definitely usable and bearable.

I can certainly live with the NT1 for a while. It seems very accurate and detailed. But solving the major problem has now given me a taste for something as accurate and detailed but less bright and dry, and a little warmer.

To see if the NT1’s brightness could be reduced, I then recorded two NT1’s, one with the DBX386’s 20 dB pad on and the input trim “drive” cranked; the other without the 20 dB pad and the input turned down as described earlier. The clear winner was without the 20 dB pad. The pad did nothing to reduce the brightness but added a noticeable and unwanted reinforcement of the fundamental frequencies and some loss of detail.

I’m a happier camper now. But I would value any comments in case I have missed a better approach that would avoid the low meter levels that characterize my solution.

Yo Mike:

You certainly sound like a hard worker in the studio. I get in that mood once in a while.

I have two main mics for vocals. The AKG C3000 and the Yorkville Apex.

I don't know the exact formula but I've reduced "harshness" by fudging with the EQ. This depends on the voice quality of the singer, as well as any mic. I found the mid range can reduce some rough edges via plus or minus.

When I used my mic pre with my MD8, I used to tinker with the input and output dials. Less input and more output would usually take out those "blasts" of singer excitement.

Now I'm using the Yam 2816 and it has some great converters as well as reverb as well as other stuff to "tinker" with. Long story short, I don't use or haven't used my mic pre to do any vocals. The 2816 works fine without it as the mic inputs on each channel do a fine job and sometimes are hardly needed.

The pop filter works fine. I sometimes use a pop filter on the mic plus the circular hook on screen that one finds in most studios.

But, as I've noticed, some folks have good mic skills when they sing; others, have good voices but do not know exactly how to use the mic.

Finally, the less I have to tinker with a vocal, except for some reverb, the better the results, usually.

:D :D :cool: :cool:
 
Any further insight or speculation will be much appreciated.

Thanks.
