Hi Everyone! Has anyone has ever used a reflection filter screen when recording vocals? I rented an Aston halo to see if it will work for me but I'm having a hard time getting used to the way my voice is sounding. I don't have a space I can soundproof so I wanted to try using a reflection screen. Does anyone have any experience with one of these filters? Any advice greatly appreciated! :) Thanks! :)

I agree they aren't great. The idea is it absorbs sound going past the mic so that less sound reflects around the room. It's so thin and small it isn't going to absorb very much. It honestly doesn't cost too much to put up some decent acoustic wall treatments if you have a little time and a few tools to do it yourself. I use Owens-Corning 703 insulation framed with some 1/2" plywood and then covered in some sheer fabric with a 2" spacing away from the wall. You can even use bookcases with books placed un-evenly as a diffuser, couches, and other things to just break up the flat surfaces of the walls. You don't have to soundproof the room to cut down on excessive room reflections coloring your recording. You can also build a vocal booth, ranging from simple - like with PVC piping and thick curtains or cushions - to more complex using more legit acoustic panels. A pillow fort would probably work. The thinner material only absorbs very high frequencies and the same is true of the "egg crate" style wavy foam, which isn't very useful unless you're only recording egg shakers.

+1 Good tips here! I didn't see that you'd already mentioned bookshelves; they're great diffusers :)

My bluegrass vocalist buddy swears by cheapie garment racks with u-haul packing blankets zip tied to them. Easy to position around you and easy to push into the corner when you're done with them.

That's a good idea

I've thought about getting a "collar of shame" for dogs & then going around the outside of that with some upholstery foam, .. where Janine, .. it looks like your Aston halo has a ribbed foam inside surface, versus a reflective smooth plastic surface, of my theory's .. but, they're the experts, .. and should have a better thing going, which you have now, .. than what I'm thinking of .. hmm .. ? If I would follow through on this notion .. I definitely would play around with the mic's position, inside the cone.

Wow!! You guys are so AWESOME!! Thank you so much for all the ideas & advice. Especially all the non-permanent solutions as I don't really have a space I can built something permanent. So many fantastic suggestions THANK YOU! xxxx I really wanted to like this filter as I can see with a simple frequency analyzer that it's taking out a lot of the low end but I think it's changing some of the other frequencies maybe too. It could also be my ears as when I first started singing with headphones I had to leave one ear off to keep from going flat. That changed over time but I'm not sure if I'll get used to this sound. Any of your excellent ideas sound like things to try. Thank you all so much again! :D

A while back my daughter got me a box of acoustic foam tiles. There were 8, each of 12 inch square. I didn't know what to do with them as there were not enough to do a wall so I came up with this idea. Two sheets of board, 4 ft x 1 ft, hinged to fold flat. Stores away like that and can be got out when needed. Stuck four tiles on each. When opened out it gives a nice 90 degree angle (or wider) to place a mic stand in. I use this sitting down but the idea could easily be adapted to be higher with the tiles just on the upper portion. Here: https://www.dropbox.com/s/1a19hp94lbx1wzx/vocal%20booth.jpg?dl=0

Thanks so much James :) I will definitely check out your design.

I picked up a great tip I got at AES for placement of these tiles that I'll pass along to you folks. This is more for tamping down reflections in your room for listening/mixing purposes.The trick is to use a hand held mirror(you need two people to do this right) that you move along the wall. If you can see a speaker from your seated position, place a tile there. The theory is that sound from the speaker will reflect off that surface and then come to you slightly delayed from the original sound. This shifted phase relationship will alter the sound. This is why your voice probably sounded strange to you since you cut out all those reflections altering the sound, but this is best for recording any source so the initial sound wave does not get affected by the reflected wave. The price of these curved reflection screens have come down a bunch, so shop around for what fits the budget. Good luck!

Hi Jeff, Nice to see you around again! That's a pretty neat trick! :)

Yes it is, and it makes sense too, which is nice because some audio concepts only make sense topeople with lots of letters behind their name! :-) And I'm not back, just dropped in to see what's going on here these days. Feeling better lately, so I might try some recording soon. Just grabbed a sub-woofer for mixing purposes, so I'm looking forward to adding that to the mix(pun intended).

Hi Janine, From the looks of it the Aston Halo would be a good solution - but it is pricy. There are some great alternatives, some of which have been mentioned here, if you want to have a better price/performance ratio. Maybe you're not comfortable with the way your voice sounds because it's too dry? In this case you could add some room to your vocals in your DAW. There are things you can do in your room to improve the acoustics without 'ruining' it with sound absorption: - Thick long curtains - Bookshelves with books - Paintings with the backside filled with insulation (easy to do) These things will dampen the room reverb effect. A variation on what Chris mentioned is to use a clothes hanger with clothes on it :)

Thanks for your suggestions! :) I did try to look at the frequency differences between Halo/no Halo and then add that back in but it was really weird and VERY LOUD lol :) I think I will work bookshelves & curtains. Thankyou :)

Thank you once again everyone for your advice! I put together a little tent with moving blankets and we will so how that goes. Tomorrow I take it for a test drive. I LOVE this site and all you generous & brilliant people. Thanks so much again! :D

I don't like how the Aston Halo makes my voice sound either. I would prefer to hang blankets on the walls. I had one behind me that made a big difference. Unfortunately, the adhesive clips I used to hang them gave way over time. So, I'm considering a more permanent solution.

Well if you both say that there's something strange with the Halo then there must be something about it. Ryan, can you describe how the sound changed?

To my ears, the Aston Halo makes my vocals sound boxy. It seems like EQ can remedy the issue, but I would prefer to capture a better sound from the source.

Sorry I missed your comment Ryan. I'm kinda glad that you noticed something weird too. :D I will try moving it behind me and see. Thanks for commenting on this. :)

No worries, Janine. I have not tried moving the Halo behind me, but I did notice a difference in room acoustics after hanging a thick/heavy blanket on the wall behind me. Sorry for not being more clear. My future goal is to hang a thick/heavy blanket on the wall in front of me as well as the wall behind me.
