This thread has really got me moving along in the thought process about building my own vocal booth...

I like this design shown here below, and after the success of building my own desk recently based on a popular design, I thought I may tackle the task of building this on my own.

Ideally, I would like something around 1 metre x 1.2 metres (approx 40 inches x 48 inches or 3 foot 4 inches x 4 foot)

This design has 5 sides with the only right angle being on the front corner where the door and window sides meet up.

Could something similar be built using only 4 sides with an offset angled wall on the rear side opposite the door, meeting a back wall opposite the window that was longer ?...
- or would that increase any comb filtering that could / would occur given its dimensions?

Maybe one of our resident acoustic specialists could chime in here with their thoughts. Worst case scenario I'd just build it with the 5 sides like the one below.

Sorry if I have hijacked your thread Chris, but this has got me thinking more about the topic and I just thought I'd put it out there.

- Maybe I could put a payphone in it as well where you have to drop a coin in the phone coin slot to get the music to start...:D

small booths can have comb filtering issues and acoustic foam won't address that. so again, you need diffusion in such a booth. room ratios still need to be considered. i read somewhere (F. Alton Everest?) years ago the ideal dimension for a small booth is 5 x 6 x 11. the only time you will get a completely unaffected sound wave free of room reflections is if you are recording outdoors.
Since you're only tracking, not mixing, you wouldn't really need bass traps
don't assume that a tracking room / booth doesn't need proper bass trapping. if there's a null or a resonant peak, a mic will pick that up.

Looks like I may have to do some more research on the subject before I do anything else. Thanks for the advice Kurt.

No worries, keep the topic alive.

I believe I read that as well. Might have been from you years back. Thanks for chiming in Kurt.

Low end issues would be less of a concern for a vocal booth for me than the upper range CF that could occur. Using an LPF could always go a long way to counter any potential low end standing waves, and most will use a lo=pass on the vocal input anyway, either on the mic itself or on a channels strip. That being said, a simple 6" OC or Roxul wedge trap in one of the corners might suffice in an area that small.
As far as the an-echoic environment you mentioned, I'm not entirely convinced that leaning this way would be a bad idea for a vocal booth - maybe not entirely, but heading in that direction. Considering that Chris has the Bricasti, I'd be leaning towards a treatment method that offered an as non-reflective environment as possible.

Ventilation is a consideration though - with any booth. You don't want your singer getting claustrophobic.
