isolation

OK, so I'm planning a room. It's a 15x30 basement room. Along the 30 foot length, there are is one HVAC duct on each side running along the ceiling with vents into the living room above. I have the ceiling pretty much figured out except how to deal with these ducts. I have other ventilation plans so I won't be using them. I just can't figure out for the life of me how to insulate them for sound isolation. I can't move or modify them.

Thanks in advance for any suggestions.

i've been using Audacity and other free programs to try and get speech from an audio recording i've legally taken ( my state is a one party record state) from my bedroom. i can make out some of the words but most of it i can`t understand. if anyone here knows where i can get a program to to where i can just hear the words being said i`d appreciate it or if someone here would like to try and get what the people are saying hmu and we`ll see what we can do.

Long story short, I keep hearing sh*t in my house, it sounds like people talking and I hear running around etc. We have cameras in our house, but they keep magically looking very grainy, I used voice amplifier but magically again...when I suspect anything..it sounds like my ear is blown off when listening...so I recorded our cameras from my phone on certain nights. and when I try to playback the audio I hear the whispers.

Hey ive been thinking about deliver clean power to my rig as it approaches completion. The use of isolation transformers seems to make sense since the rig will be in a regular house, without any modifications to the existing electric service. My questions are:

1. What pieces of gear need to be plugged into an isolation transformer?

• Powered Studio Speakers?
  
• Audio Interface/Converters?
  
• The Computers?
  
• Outboard pres, comps, eqs?
  
• Guitar Amps?

I'm planning to sound-isolate an already-converted garage built on concrete slab. I want to modify the walls to have mass-air-mass with two layers of drywall inside and out.

The room has rigid foam insulation around the slab that protrudes into the room. The insulation, framing, and the drywall installed over it take up an additional 6"+ around the room perimeter. It seems the only way not to disturb the insulation is to add parallel framing on the inside, which I'd really like to avoid.

This is an interesting set of interactive demonstrations showing the effect of microphone positioning relative to a performer. All the extracts are recorded using DPA4006A omni microphones in A-B configuration in a good acoustic.

Recently we've had lots of topics on choosing mics, and the usual X is good and Y is bad result soon pop up.

Today I needed to record a double bass for a track in the works, but as I had some spare time I thought I'd go through the mic stock and try mics I'd not usually pick, just to see what happened.

I have an 8'x12' corner available within a larger room (with 8' ceiling) for a vocal isolation booth.

Any builder recommendations in the Eastern Connecticut area who can get it quiet in there? I'm on the fence about doing it myself - if I can avoid construction I'd like to.

Thanks!

Ill try to make this short.

My wife and I just moved into our new build house. I am wanting to construct a home studio in the basement that can later be a nice man cave and/or home theater for the next buyers.

I read through Rod Garvais' book, and it seems a little over my head, but there are good points that I could take away from it.

Have 29 sec audio need to know what is being said. Total novice. Use the Donnin and it makes it understandable. But not by everyone. Any takers? Email-stuckwithcheater@gmail.com
