Compressor/Limiters: The Ultimate Guide

Introduction

Compressor/limiters are an essential tool in the recording and mixing process. They help control the dynamics of a sound source, making it sound more polished and professional. In this article, we’ll cover everything you need to know about compressor/limiters, including their primary controls, types, famous models, and setup.

Primary Controls

Threshold

The threshold control determines the level at which compression starts to occur. Signals below the threshold remain unaffected, while signals above the threshold are compressed.

Attack Time

The attack time control determines how quickly the compressor reacts to signals above the threshold. A fast attack time is suitable for controlling transients, while a slower attack time can help maintain the natural character of the sound.

Release Time

The release time control determines how quickly the compressor stops compressing after a signal falls below the threshold. A fast release time is suitable for percussive sounds, while a slower release time can help maintain the natural decay of the sound.

Compression Ratio

The compression ratio control determines the amount of compression applied to the signal above the threshold. A higher ratio results in more compression.

The compression ratio is like a volume knob that turns down the loud parts of a sound. The higher the ratio, the more the loud parts are turned down. A ratio of 2:1 means that for every 2 loud parts, the compressor turns down 1 of them. A ratio of 4:1 means that for every 4 loud parts, the compressor turns down 1 of them. A ratio of 8:1 means that for every 8 loud parts, the compressor turns down 1 of them. When the ratio is set to infinity, it means that the compressor won’t let anything go over a certain level, so it’s like a volume limit. Imagine you have a music player and set a maximum volume level so it doesn’t get too loud and hurt your ears. That’s what a limiter does. It sets a maximum level for the sound so it doesn’t get too loud and cause damage to your ears or the equipment.

Typical ratios you’ll find on most compressors include:

  • 2:1 – For every 2 dB that the signal goes over the threshold, the output will be compressed by 1 dB. This is a mild compression ratio that is suitable for subtle dynamic control.
  • 4:1 – For every 4 dB that the signal goes over the threshold, the output will be compressed by 1 dB. This is a moderate compression ratio that is suitable for general-purpose dynamic control.
  • 8:1 – For every 8 dB that the signal goes over the threshold, the output will be compressed by 1 dB. This is a high compression ratio that is suitable for heavy dynamic control.
  • Infinity:1 – The output will be fixed at the threshold level when the compression ratio is set to infinity. This is known as limiting and is used to prevent signals from exceeding a certain level.

Side Chain

The side chain input allows an external signal to be used to trigger the compressor. This is useful for de-essing, ducking, or frequency-specific compression.

Possible Uses

  • De-essing: using a frequency-specific signal to reduce sibilance in a vocal recording
  • Ducking: reducing the level of music when a voice-over is present
  • Frequency-specific compression: compressing only a specific frequency range of a signal

One interesting use of side chain is to create unique effects. For example, you can use a kick drum to trigger a compressor on a bass guitar track, resulting in a pumping effect that is often heard in dance music. Another example is to use a vocal track to trigger a delay effect on a guitar track, creating a rhythmic pattern that complements the vocal melody. The possibilities are endless, and experimenting with side chain can lead to some truly creative results.

Bypass

The bypass control allows the compressor to be bypassed, allowing the original signal to pass through unaffected.

Types of Compressors

Optical

Optical compressors use a light-dependent resistor (LDR) to control the amount of gain reduction. They are known for their smooth and musical sound.

Example: Teletronix LA-2A

The Teletronix LA-2A is a legendary optical compressor that has been used on countless recordings. Its smooth and transparent sound makes it a favorite among engineers and producers.

Example: Universal Audio 1176

The Universal Audio 1176 is a classic FET compressor that has been used on countless recordings. Its fast attack time and aggressive sound make it a favorite among rock and pop engineers.

VCA

VCA (voltage-controlled amplifier) compressors use a VCA to control the amount of gain reduction. They are known for their transparent sound and fast response.

Example: DBX 160

The DBX 160 is a classic VCA compressor that has been used on countless recordings. Its transparent sound and fast response make it a favorite among engineers and producers.

Vari-Gain

Vari-Gain compressors use a variable gain amplifier to control the amount of gain reduction. They are known for their warm and musical sound.

Examples: Fairchild 670 or Manley Vari-Mu

The Fairchild 670 and Manley Vari-Mu are classic Vari-Gain compressors that have been used on countless recordings. Their warm and musical sound makes them a favorite among engineers and producers.

Direct Injection: Everything You Need to Know

Direct injection is a technique used in music production to connect instruments, such as guitars and keyboards, directly to the mixing console or recording device. This technique has become increasingly popular in recent years due to its ability to cut down on the number of microphones used, as well as its impact on the overall sound quality of the instrument. In this article, we’ll explore everything you need to know about direct injection, including its advantages, types of direct boxes, setup, and amplifier emulators.

Why is Direct Injection Used Today?

Direct injection is used in music production today for a number of reasons. One of the main reasons is to reduce the number of microphones used. This is because when an instrument is recorded using a microphone, it can pick up unwanted sounds, such as room noise and other instruments. By using direct injection, these unwanted sounds can be eliminated, resulting in a cleaner recording.

Another reason direct injection is used is to improve the overall sound quality of the instrument. When an instrument is recorded using a microphone, the sound can be distorted due to the distance between the microphone and the instrument. Direct injection eliminates this issue by allowing the instrument to be connected directly to the mixing console or recording device, resulting in a more accurate and natural sound.

How Does Direct Injection Cut Down on the Number of Mics Used?

Direct injection cuts down on the number of microphones used by allowing the instrument to be connected directly to the mixing console or recording device. This eliminates the need for a microphone, as the instrument’s sound is captured directly through the direct box.

How Does Direct Injection Make the Instrument Sound? Is it Better or Worse?

Direct injection can make an instrument sound better or worse depending on various factors, such as the quality of the direct box and the instrument being used. However, in general, direct injection is known for producing a more accurate and natural sound compared to recording with a microphone.

1/4” Cables vs Balanced XLR Mic Input

When using direct injection, it’s important to understand the difference between 1/4″ cables and balanced XLR mic input. 1/4″ cables are unbalanced, which means they are more susceptible to interference and noise. Balanced XLR mic inputs, on the other hand, are designed to eliminate interference and noise, resulting in a cleaner sound.

Converting Between 1/4” and Balanced XLR

Converting between 1/4″ and balanced XLR can be done using a direct box. Direct boxes are designed to convert unbalanced signals, such as those from a 1/4″ cable, into balanced signals, such as those used by a balanced XLR mic input.

Why Can’t You Directly Plug Your Guitar or Keyboard into the Mic Preamp Without the Direct Box?

You can’t directly plug your guitar or keyboard into the mic preamp without the direct box because most instruments have an impedance that is too high for the mic preamp to handle. Direct boxes are designed to match the impedance of the instrument to the impedance of the mic preamp, resulting in a cleaner sound.

Advantages of Direct Injection

Direct injection offers a number of advantages, including:

Direct-Box Transformers

Direct-box transformers are designed to match the impedance of the instrument to the impedance of the mic preamp. This results in a cleaner sound, as the transformer eliminates any unwanted noise or interference.

Extremely High Impedance

Direct boxes have an extremely high impedance, which means they are less susceptible to noise and interference. This results in a cleaner sound and a more accurate representation of the instrument.

Length of Balanced Output Cable

The length of the balanced output cable can affect the sound quality of the instrument. Direct boxes are designed to compensate for this by providing a balanced output that can be used with longer cables without affecting the sound quality.

Converting Between Cable Types

Direct boxes are designed to convert between cable types, such as 1/4″ and balanced XLR. This allows for greater flexibility when connecting instruments to the mixing console or recording device.

Direct-Box Types

There are two main types of direct boxes: active and passive.

Active vs Passive

Active direct boxes require power, either from a battery or phantom power from the mixing console or recording device. Passive direct boxes, on the other hand, do not require power and are designed to work with low-impedance instruments.

Which is Better?

The choice between active and passive direct boxes depends on your specific needs. Active direct boxes are generally more versatile and can be used with a wider range of instruments, while passive direct boxes are simpler and easier to use.

Modern Mic Preamps and DI Inputs

Many modern mic preamps and DI inputs are designed to work with both active and passive direct boxes, making it easier to use either type of direct box.

Direct-Box Setup

Setting up a direct box involves several steps, including:

Setting the Gain

Setting the gain on the direct box is important to ensure that the instrument is not overdriven or underrepresented.

Boost

Some direct boxes come with a boost function, which can be used to increase the level of the instrument’s signal.

Ground Switch

The ground switch on the direct box is used to eliminate any hum or noise that may be caused by ground loops.

Reducing Hum

Hum can be reduced by ensuring that the instrument is properly grounded, and by using a direct box with a ground lift switch.

Amplifier Emulators

Amplifier emulators are devices that are designed to simulate the sound of a guitar amplifier. These devices can be used in conjunction with a direct box to create a more realistic sound. However, there are some advantages and disadvantages to using amplifier emulators.

What is the Purpose of These?

The purpose of amplifier emulators is to simulate the sound of a guitar amplifier, which can be useful when recording or performing live.

What Do They Do?

Amplifier emulators simulate the sound of a guitar amplifier by using digital signal processing to create a similar sound.

How Do They Do It?

Amplifier emulators use digital signal processing to create a similar sound to a guitar amplifier.

Advantages vs Disadvantages?

The advantages of using amplifier emulators include the ability to create a more realistic sound, as well as the ability to use the same sound across multiple recordings. The disadvantages include the cost of the emulator, as well as the fact that it may not be as versatile as a physical guitar amplifier.

The Microphone Preamplifier: Choosing the Best Vintage and Modern Models for Better Sound Quality

A microphone preamplifier, also known as a mic preamp, is an essential component in recording audio. It is a device that amplifies the low-level output signal of a microphone to a higher level that can be recorded or processed further. In this blog post, we will discuss the importance of using a separate mic amp, vintage and modern mic preamp models, 500 series racks, mic amp setup, primary controls, and setup method.

Why A Separate Mic Amp?

While some audio interfaces come with built-in mic preamps, it is often recommended to use a separate mic amp for several reasons. Firstly, a dedicated mic preamp can offer a higher quality and cleaner amplification of the microphone signal, resulting in better sound quality. Secondly, it allows for more control over the sound, as the mic preamp is a separate unit with its own set of controls. Finally, using a separate mic preamp allows for more flexibility in terms of routing and processing.

Mic Amp Setup

When setting up your mic amp, there are several primary controls to be aware of:

Gain

The gain control adjusts the amount of amplification applied to the microphone signal. It is important to set the gain properly to avoid clipping or distortion. The gain should be set so that the loudest part of the recording is just below the maximum level.

Phantom Power

Many microphones require phantom power to operate. This is a +48V DC voltage that is applied to the microphone through the mic cable. Make sure your mic preamp has a phantom power switch and that it is turned on when using a microphone that requires it. Not all microphones require phantom power, so it’s important to check the microphone’s specifications before turning on phantom power.

Phase

The phase switch or button is used to adjust the polarity of the microphone signal. This can be useful in certain situations where multiple microphones are being used and their signals are interacting with each other. If two microphones are picking up the same sound source, but one is slightly out of phase, the two signals can cancel each other out, resulting in a thinner, weaker sound. Flipping the phase of one of the microphones can fix this issue.

High-Pass Filter

The high-pass filter, sometimes called a low-cut filter, removes low-frequency content from the microphone signal. This can be useful in reducing rumble or other unwanted low-frequency noise. The high-pass filter should be set based on the frequency of the noise you’re trying to remove. If you’re recording vocals, you can usually set the high-pass filter to around 80 Hz.

Setup Method

When setting up your mic amp, it is important to follow a few best practices:

Use Quality Cables

Using high-quality cables will help minimize noise and interference in the signal chain. Look for cables with high-quality connectors and shielded cables. The type of cable you use will depend on the type of microphone you’re using. For dynamic microphones, you can use a standard XLR cable. For condenser microphones, you will need a cable that can carry phantom power.

Test and Adjust Levels

Before recording, it is important to test and adjust the levels of your mic preamp. Use a reference signal and adjust the gain control until the signal is at an appropriate level. The signal should be loud enough to be heard clearly, but not so loud that it clips or distorts.

Experiment with Mic Placement

Mic placement can have a significant impact on the sound of your recording. Experiment with different mic positions and distances to find the sound that works best for your recording. The distance between the microphone and the sound source can affect the amount of room sound in the recording. The angle of the microphone can affect the high-frequency response of the recording.

In conclusion, a high-quality mic preamp is an essential component in recording audio. Whether you choose a vintage or modern model, or build your own, the mic preamp offers a level of control and flexibility that can help you achieve the sound you’re looking for. Take the time to research different models and test them out before making a purchase. And don’t be afraid to experiment with mic placement and other settings to find the perfect sound for your recording.

Microphone Specifications

When choosing a microphone, it’s important to consider its specifications. Here are some key specifications to look at:

Sensitivity

Sensitivity is a measure of how much output voltage a microphone produces when it’s exposed to a certain sound pressure level. In general, a higher sensitivity microphone will produce a stronger signal than a lower sensitivity microphone.

Overload Characteristics

Overload characteristics refer to a microphone’s ability to handle high sound pressure levels without distorting. If you plan on recording loud sources like drums or guitar amps, you’ll want a microphone with good overload characteristics.

Frequency Response

A microphone’s frequency response is a measure of how evenly it responds to different frequencies. Some microphones are designed to have a flat frequency response, while others are designed to emphasize certain frequencies.

Free-Field or Diffuse-Field

Free-field microphones are designed to be used in environments where sound arrives directly from the source. Diffuse-field microphones are designed to be used in environments where sound is evenly distributed.

Noise

Noise refers to any unwanted sounds that a microphone might pick up. Some microphones are designed to have very low noise levels, which is important if you’re recording quiet sources like vocals.

Directional Response

Directional response refers to a microphone’s ability to pick up sound from different directions. Here are some common directional patterns:

Omni-Directional

Omni-directional microphones are a type of microphone that pick up sound from all directions equally. They are often used in recording studios to capture the natural and ambient sound of a room. These microphones are also useful for recording live music performances, as they can capture the sound of a group of musicians playing together. In addition, omni-directional microphones can be used in field recordings to capture the sounds of nature or the environment. With their ability to capture sound from all directions, omni-directional microphones provide a versatile and high-quality recording option for a variety of applications.

  • Rode NT2-A: This versatile condenser microphone has three polar patterns, including bi-directional, and is well-suited for recording a variety of instruments and vocals.

Figure Of Eight

Figure-of-eight microphones are a type of directional microphone that is designed to pick up sound from two opposite directions while rejecting sound from the sides. This makes them particularly useful for recording two sources at the same time, such as a guitar and a vocal. The unique shape of the microphone allows it to pick up sound in a pattern that resembles the figure “8,” which is why it’s called a figure-of-eight microphone.

These microphones work by using two diaphragms that are placed back-to-back. When sound waves reach the diaphragms, they create a pattern of positive and negative pressure. The diaphragms are connected to an electrical circuit that converts the pressure changes into an electrical signal, which can then be recorded or amplified.

One of the advantages of using a figure-of-eight microphone is that it allows you to achieve a natural sound that captures the ambience of the room. Since the microphone is only picking up sound from two directions, it’s less likely to pick up unwanted sounds from the sides, such as noise from an air conditioner or traffic outside. This can be especially useful in a live recording situation, where you want to capture the energy of the performance without any distractions.

Another advantage of using a figure-of-eight microphone is that it gives you more control over the balance of the two sources. By adjusting the placement of the microphone, you can emphasize one source over the other, or you can blend them together in a way that sounds pleasing to your ears. This can be particularly useful when recording instruments and vocals, where you want to achieve a balance that highlights the strengths of each source.

Figure-of-eight microphones are a versatile tool for recording music and other types of audio. Whether you’re recording a live performance or a studio session, these microphones can help you achieve a natural sound that captures the essence of the performance. So if you’re looking for a way to take your recordings to the next level, consider adding a figure-of-eight microphone to your collection.

Some of the most popular figure-of-eight microphones include:

  • Rode NT2-A
  • Audio-Technica AT4053B
  • AKG C414 XLII

Cardioid

Cardioid microphones are a type of directional microphone that picks up sound from the front while rejecting sound from the sides and rear. They are ideal for recording a single source, such as a vocalist or a guitar amp, with minimal bleed from other sources. However, it is important to note that cardioid microphones are not suitable for recording ambient sounds or multiple sources in a room, as they will not capture a complete picture of the acoustic environment. Additionally, cardioid microphones can come in different shapes and sizes, such as handheld or shotgun mics, and may be used in a variety of settings, from recording studios to live concerts. Overall, the versatility and directional properties of cardioid microphones make them a popular choice among audio professionals and enthusiasts alike.

Some popular cardioid microphones include:

  • Shure SM7B: A favorite among podcasters and broadcasters, this dynamic microphone has a smooth, warm sound that’s great for vocals.

  • AKG C414 XLII: This versatile condenser microphone has five polar patterns, including cardioid, and is well-suited for a wide range of recording applications.

Hyper-Cardioid

Hyper-cardioid microphones are a type of directional microphone that are similar to cardioid microphones. While cardioid microphones have a wide pickup pattern that captures sound from multiple directions, hyper-cardioid microphones have a much narrower pickup pattern that only captures sound from a smaller area directly in front of the microphone. This makes them ideal for recording a single source in a noisy environment, such as a concert or live event.

In addition to their directional capabilities, hyper-cardioid microphones also have a number of other features that make them a popular choice for recording engineers and audio professionals. For example, they often have a built-in shock mount to help reduce handling noise, and some models even have a switchable polar pattern that allows them to be used as a standard cardioid microphone when needed. Overall, hyper-cardioid microphones are a versatile and reliable tool for anyone looking to capture high-quality audio in challenging recording environments.

Some popular hyper-cardioid microphones include:

  • Sennheiser e965: This condenser microphone has a switchable polar pattern, allowing you to switch between cardioid and hyper-cardioid modes. It’s great for recording vocals in a noisy environment.
  • Rode NT2-A: This versatile condenser microphone has three polar patterns, including hyper-cardioid, and is well-suited for recording a variety of instruments and vocals.
  • Audio-Technica AT4053B: This condenser microphone has a flat, extended frequency response and a hyper-cardioid polar pattern, making it ideal for capturing the nuances of acoustic instruments.
