In this guide, I will present easy, low-budget solutions for building your own home-based audio recording studio. Whether you are an amateur looking to record for the first time or you are an experienced musician looking to get your own studio, this guide will explore the components needed to produce professional sound.
Advantages of having your own home recording studio include:
• Saving money on studio time
• Having recording access whenever you want
• Having more control over your music
Like many other technologies of modern times, audio equipment is getting smaller, cheaper and more advanced, faster than ever. In addition, computer software can now handle a lot of the functions which once required big, expensive rack-mounted equipment. With all the advances of today’s audio equipment, amateur musicians can now put together an audio recording setup capable of producing professional sound for a fraction of the price spent on commercial studios.
STAGE 1: PRE-AMPLIFIER/USB/Firewire Audio Interface
Microphone pre-amplifiers are the most crucial component of the studio. The pre-amp is where the 48V phantom power amplifies the mic signal for processing. Without a good pre-amp, a $2000 Neumann mic wouldn’t sound much better than a $100 budget mic. It is not common for the high-budget home studios to invest the bulk of their money on their pre-amps.

Pre-amps tend to have their own “sound” to them and for most uses, a warm sound is what you are looking for. Also, a low-noise pre-amp is desirable because noise is created when the gain (volume) of the signal is increased.
It is hard to find the right pre-amp by studying specifications. Generally the tube-style pre-amps sound the best, but using customer reviews or talking to other musicians is the best bet when choosing a pre-amp.
Audio interfaces are also called external cards because they perform in the same way, except they are connected to the computer with a USB or Firewire cord. In addition, most interfaces have their own built-in pre-amps so you won’t have to buy a pre-amp to pair with your other equipment. The main advantages of having external audio interfaces is the simplicity of combining a soundcard with a pre-amp and its portability.
STAGE 2: MICROPHONES

Microphones: What to Look for…
• Wide Frequency Range (20Hz to 20kHz or higher)
o Basically the wider the range, the better the mic will sound. However, a range higher than 20Hz to 20kHz is not necessary since the range of human hearing is 20Hz to 20kHz.
• High Signal-to-Noise Ratio
o This number measures the amount of signal (vocals, guitars, etc.) to background noise. The higher the ratio, the less noise the microphone will pick up.
• High Maximum SPL (Sound Pressure Level)
o This value represents the highest level of dB (decibels) that the microphone can handle before being distorted. The higher the number, the better sound.
• -10dB Pad
o This feature usually is found as a button on the microphone. This pad eliminates excessive low frequencies caused by the proximity effect. When recording at close proximities, low-pitch frequencies are accentuated making a muddy sound, the same way it sounds when talking too close to a telephone. This feature is useful when working with vocals because it automatically removes some of the extra low frequencies before it is sent out of the microphone.
• Variable Directional Patterns
o This feature allows the user to control which directions you want to emphasize when recording. For most uses, unidirectional is the best setting in the studio because it limits recording to one side of the diaphragm which results in less noise from the backside of the mic. The omnidirectional setting records from all directions and can be used for a recording with a surrounding source.
Microphone Accessories
o Microphone Stand – A sturdy microphone stand is a must when using delicate condensers and the three-legged adjustable model s makes storage easy.
o Pop Filter – A pop filter is simply an attachable screen which is used on vocals to create a barrier between the vocalist and the mic itself. In close proximities, the p- and t- words tend to create pops or knocks as the air from the consonants hit the diaphragm. The pop filter absorbs the air pressure while letting the vocals pass through the porous screen. This cheap investment is a must when recording vocals and the metal models are best since it makes cleaning easier (get rid of that stinky breath!).
o Wall foam – Reflections from the walls in home studios are worse than you expect. Putting foam on the walls to absorb the sound lessens the effects of wall reflections on your work. It is common for the casual musician to not want to foam the whole room or have the budget for a recording booth so simply foaming the corner of a room, a closet or a fold-out wall would make a big difference.
STAGE 3: ADDITIONAL HARDWARE PROCESSORS

At the capture stage of the musical process, many professional studios incorporate other hardware devices to further control the audio before it reaches the computer. These devices include:
o Mixer
o Also called the mixing board, this component can be recognized by sets of knobs, plugs, and sliders. The purpose of the mixer is to control the levels of microphones, speakers, and effects which are applied before reaching the computer.
o Compressor
o This gadget helps normalize audio by boosting low-volume parts of the recording while decreasing high-volume parts. This is useful when recording because it helps ensure that the recording is loud enough while preventing clipping (when a recording is too loud and distorts).
o Equalizer (EQ)
o This component fine tunes specific frequencies of the recording. For example, lowering the high-frequencies can reduce hiss while a low-frequency boost can give a bassy boom to your recording. This function is for more advanced users and the destructive nature of hardware equalizers has made software a lot more manageable for home studios.
o Reverb
o This effect can be placed on recordings to give it the echoey church effect. This is useful when taking a dry recording and making it sound more natural. Once again, this effect is harder to control in hardware setups than it is in software.
Since most of these features are available on recording software, signal processing hardware in home studios is declining due to cost, size and its destructive qualities.
OK, let me back up. For those of you that don’t know what destructive components are, being destructive means that the audio is processed before being saved so the changes are permanent. Let’s say we put a little too much reverb on some vocals while using a reverb box. When the audio is received in the computer, the reverberated track is uniform and the reverb is now included in the single track.
Taking out the small echos after they have been applied is hard and degrades the quality of the recording. The advancement of technology and having the freedom to go back and change effects is the main reason why signal processing is increasingly being done by software instead of hardware.
Many of the pros use hardware signal processors because they take processing strain away from your CPU, but software processors aren't very far behind quality-wise and they are often cheaper.
