About FAQ

Currently Under Construction

The Frequently Asked Questions (faq) module allows users, with appropriate permissions, to create question and answer pairs which they want displayed on the 'faq' page. The 'faq' page is automatically generated from the FAQ nodes configured. Basic Views layouts are also provided and can be customised via the Views UI (rather than via the module settings page).


The layout of the FAQ page can be modified on the settings page. There are four question and answer layouts to choose from. In addition, if the 'Taxonomy' module is enabled, it is possible to put the questions into different categories when editing. Users will need the 'view faq page' permission to view the built-in 'faq' page and will need the 'administer faq' permission to configure the layout, etc.

There are 3 blocks included in this module. The first shows a list of FAQ categories. The other two can show a configurable number of FAQs - one shows recent FAQs, while the other just displays random ones.


Microphone patterns


What is the difference between cardioid and omnidirectional?

Omnidirectional microphones are microphones that hear everything that's going on around them. They are equally sensitive to sound from all directions. ... Cardioid microphones “listen” to sound from the front and reject sound from the rear.

What are the 3 types of microphone pickup patterns?

There are three basic types: omnidirectional, unidirectional and bidirectional (also called figure-of-eight)

What does pattern mean on a microphone?

Directionality refers to the sensitivity relative to the direction or angle of sound arriving at the microphone. Directionality is usually plotted on a graph referred to as a polar pattern. A polar pattern graph shows the variation in sensitivity as you move 360 degrees around the microphone

What are different types of microphone?

Dynamic Microphones.
Large Diaphram Condensor Microphones.
Small Diaphram Condensor Microphones.
Ribbon Microphones.

Pro Audio Mastering

Detailed Question

I know the importance of mastering by a mastering engineer but trying to tell most of my clients this is like speaking to them in Latin. My mastering guy has given me some good things to say that helps, but most of them really don't get it, all they hear is what it cost and all things considered it's pretty cheap.

What's the best way to teach them!


What does mastering mean in pro audio?

Mastering means preparation of a master copy for replication

  1. Traditionally, mastering is performed by a specialized facility using custom and/or high-end monitoring, playback and signal processing gear to correct whatever shortcomings are found in the tonal balance and dynamics. A mastering engineer's job is to bring out the very best in a recording.
  2. The major components of mastering are quality control, experience evaluating how effectively one's work will compete in the marketplace and the technical skills and facilities necessary to make such judgments and then utilize them to create a competitive, technically bullet-proof master.
  3. Most mastering engineers are former employees that were trained by the major labels or by the independent mastering houses that work for the major labels. Broadcasting is another, although less common background that some mastering engineers have.
  4. Audio manufacturers and software developers have redefined the term lately to put an impressive-sounding spin on their advertising rhetoric. Transferring, signal processing and burning CDs are purely incidental to mastering.

Studio Acoustics & Construction

Insulation vs Isolation

The most effective insulation to use for your studio wall cavities is the cheapest, standard "fluffy", insulation. This insulation has good acoustical and thermal performance, and is relatively low cost.

When it comes to isolation the type of insulation you use will have little effect. There is generally no reason to use anything but the cheapest insulation you can get, to fill your wall cavities.


What types of insulation should I use in my studio walls?

For studio walls, in the wall cavities, the cheapest "fluffy" insulation should be used.  A standard low density (and low GFR) insulation, will do what you need wall cavity insulation to do.

What types of insulation should I avoid in my walls?

  • Any sort of "blown in" loose insulation, as it can sag over time, making your isolation worse.
  • Any sort of cellulose foam type insulation, it makes isolation worse
  • Rigid foam insulation makes isolation worse
  • Semi-Rigid insulation, like Owen Corning 703, or Rockboard. These are expensive, and not meant for wall cavities. They are effective for treating the interior of your studio as acoustic absorbers

Is Semi-Rigid insulation good for sound isolation?

Semi-Rigid insulation like Owen Corning 703, or Rockboard are expensive, and not meant for wall cavities. They are effective for treating the interior of your studio as acoustic absorbers

Which Type of Insulation Should I Use In My Studio Walls?

For studio walls, in the wall cavities, the cheapest "fluffy" insulation should be used.  A standard low density (and low GFR) insulation, will do what you need wall cavity insulation to do.

What will insulation do for my studio walls?

It will dampen resonances in the wall cavity. (Think palm muting a guitar, or moon gels on drum heads)

It will increase isolation by 3-6 decibels.

Is cellulose foam type insulation good for recording studio walls?

No. Any sort of cellulose foam type insulation makes isolation worse.

My building code requires "fire safe" insulation, what do I use?

In some cases building code will require you to use a mineral wool type insulation, also known as "fire safe" insulation.  If this is the case then use the cheapest, lowest density mineral wool available.

How do I identify insulation type and thickness?

Thicknesses are named with a capital R, then a number. Example R-19. Insulation comes in various thicknesses, in large rolls, or strips (called "batts").

How much db difference is there between isolation vs uninsulated walls?

Insulation will offer 3-6db of isolation when used in wall cavities, compared to an uninsulated wall.

What thickness should i use?

Use insulation that is the thickness of the framing. A 2x4 wall frame would need 4" thick insulation.

Is more insulation better?

No. You should only use enough insulation to loosely fill the wall cavity.

What are common installation mistakes?

  • Packing insulation too tightly. Insulation should be loosely packed in the wall cavity. It shouldn't create a firm or solid connection between to isolated wall frames.
  • Not securing the insulation properly allowing it to sag, or fall out of wall frame.

Can i fill the airspace between two isolation walls?

Yes. The entire airspace can be filled, but should be loose packed. Packing too tight will make isolation worse, by forming a hard connection between wall frames.

My insulation has expanded into the airspace between walls, is this ok?

Yes, as long as it is loosely touching, not packed tightly, or creating a hard connection (acoustic bridge) between walls.

Insulation will naturally expand slightly, and extend into the airspace between walls. This is not a problem, presuming standard size insulation, and a 1" or more airspace between walls.
