In this tutorial we will make a DIY portable mini vocal booth that can be used to record your voice on the road (on a flash disc recorder). But there's more that can be done with this easy to make project.
You can cancel background noise when doing Foley recordings in your project or home studio, or have a portable mini dead room, ideal for specialized field recording.
The DIY Portable Mini Vocal Booth is ideal for podcasters, DIY filmakers and sound designers alike. My personal motivation to build this, was a desire to have a mobile mini deadroom to make foley recordings and recordings for my music.

Signing UpStep 1: Why a Mini Vocal Booth?
While a recording session with live played instruments might involve one or multiple 'room' mic's to enhence the sound, some recordings need to be as small and 'dead' as possible.
In Short: If you dont have a treated room your audio quality gets comprimised by the reflections of soundwaves on hard surfaces in your room. A deadroom or treated room, ensure a clean recording with as little 'room' or 'echo' as possible. Once you have the perfect recording you can treat the audio with any reverb, effect processor or VST you come up with. Its better to add things later than not being able to remove things later.
IR / Convolution reverb
A common practise in sound design is applying an Impulse respondse (IR) Reverb to a recording. A IR reverb uses the actual reverb of a room. like the name suggests, an impulse, like a loud clap or a starters pistol, triggers a decay. The charactaristics of a room can be applied to any sound source this way. The less room in a recording the better the results will be when you use a IR reverb. There are IR kits featuring crazy rooms like a pharao's tombe chamber in a pyramid, but you can also choose what seat you'd like to have in carnegie hall. More info aboutIR reverbs

and if in dire need you can replace the entire material with just the egg carton.
"Similarly, acoustic foam tiles which help in sound proofing and the limitation of acoustic resonance have a similar form to egg crates. Egg crate mattresses are occasionally used as an inexpensive but poor substitute to acoustic foam."

But I think a lot of the cheaper waffle liners are that "foamy" foam that may or may not be close enough to rubber for the best attenuation, but it will still do.
Stuff on there ranging from about $0.90 per sq ft to $2.20, which seem relatively good.
At the very least seems cheaper than the other guys, and it's nearly the same exact stuff material wise.
Although it irks me slightly that they don't have the really nice deep wedges.

(Again, I'm not criticizing you. I just thought it was valid to bring the attention of readers to this. Your project is great, cheap and simple, like all good ideas seem to be, and I'm doing one myself for a school movie project I'm involved with now).
