Breaking It Down

Parallel compression, also known as New York compression, is a mixing technique that involves blending an unprocessed (dry) audio signal with a heavily compressed version of the same signal.

By combining the two signals, you can achieve a fuller, more polished sound while preserving the natural dynamics of the original audio.

Parallel compression is a form of parallel processing, a technique used in audio production to apply effects or processing to a copy of a signal instead of the original.

This approach allows you to maintain the integrity of the original audio while adding depth, texture, and character through various processing techniques.

In music production, parallel compression is crucial for several reasons, including:

• Increase the perceived loudness of your mix without adding distortion or clipping ✓
• Enhance clarity and detail ✓
• Preserve the dynamic range of your tracks ✓

By mastering this technique, you can create professional-sounding mixes that stand out in a competitive industry.

How To Apply Parallel Compression

Parallel compression is widely used in various aspects of music production, from enhancing drums and vocals to adding depth to guitars and bass.

By understanding when and how to apply parallel compression, you can elevate the quality of your mixes and achieve a polished, professional sound.

• Drums

Parallel compression is particularly effective on drums, where it can add punch and power without squashing the dynamic range.

By blending the original drum kit sound with a compressed one, you’ll achieve a larger-than-life drum sound that cuts through the mix.

When applying parallel compression to drums, try using a fast attack and release setting on the compressor to emphasize the transient energy and create a punchier sound.

Pro Tip: Alternatively, if you really want to “smash” the drums, and incorporate more of the DRY signal, use a medium-long attack & release time. This creates ideal “smearing.”

• Vocals

When mixing vocals, parallel compression can help you achieve a more consistent and powerful performance.

By combining the dry vocal signal with a compressed version, you can bring out the details and nuances of the performance while maintaining the natural dynamics.

When working with vocals, try using a medium attack and release setting on the compressor to allow the transients to pass through while still controlling the overall level.

Enhance Your Mixes

Using parallel compression in your mixes can offer several advantages, such as:

• Increased loudness and presence without overcompressing the audio
• Preserved dynamic range while adding thickness and power
• Improved clarity and detail in your mix
• Enhanced control over the balance between compressed & uncompressed signals

By applying parallel compression, you can achieve a thicker, more polished sound without sacrificing the natural dynamics of your mix.

This powerful technique allows you to maintain the clarity and punch of your original audio while adding depth and presence to your tracks.

As a result, parallel compression can enhance the listening experience and create a more professional, radio-ready sound for your music.

Add Parallel Compression To Your Tracks

By adhering to the following steps, you’ll be able to optimize the impact of parallel compression on your tracks and produce mixes that truly stand out in the competitive world of music production.

1. Create an auxiliary (aux) track or bus in your DAW and route the audio track you want to process to this aux track.
2. Insert a compressor plugin (or, plug ins) on the aux track, and adjust the settings for a heavy compression (e.g., a high ratio, low threshold, and appropriate attack and release times).
3. Blend the compressed signal from the aux track with the original, dry signal on your source track.

Use the aux track’s fader or a mix knob (if available) to find the perfect balance that enhances your mix without overpowering the original sound.

Downward Compression vs. Upward Compression

Parallel compression typically uses downward compression, but it’s essential to know the key differences between these techniques to select the best approach for your mix.

• Downward Compression 一 Reduces the dynamic range of a signal by attenuating the loudest parts
• Upward Compression 一 Increases the level of quieter parts, effectively making the quiet parts louder

The key difference between upward and downward compression lies in how they affect the audio signal.

For a vocal track with a wide dynamic range, downward compression can help you tame the loudest parts.

Upward compression, on the other hand, can bring up the level of softer phrases, ensuring a more consistent performance.

Gain Reduction

Gain reduction refers to the amount by which a compressor reduces the level of a signal when the signal exceeds the set threshold.

Understanding gain reduction is crucial when using parallel compression.

It determines the balance between preserving dynamic range and adds power to your mix, making it seem pristine and refined.

Gain reduction helps to tame peaks and transients in your audio, allowing for a smoother and more polished sound.

By adjusting the gain settings on a compressor, you can control the amount of compression applied to the audio signal and fine-tune the balance between loud and quiet parts.

Tip: Start with a moderate amount of gain (around 6-10 dB) reduction and adjust as needed to find the sweet spot that enhances your track without squashing the dynamics.

Make up gain is an essential parameter in the reduction of gain process, as it compensates for the volume lost due to compression.

By applying makeup gain after compression, you can bring the overall level of the audio signal back up.

This will help to ensure you produce a balanced and consistent output without sacrificing the dynamic control achieved through gain reduction.

Parallel Compression vs Classic Compression

Parallel compression differs from traditional compression in that it blends a compressed signal with the original, dry signal.

This approach allows for more control over the balance between preserving dynamics and achieving a fuller, more powerful sound.

When using traditional compression, consider using lower ratios and higher thresholds to maintain a more natural sound.

For parallel compression, don’t be afraid to use higher ratios and lower thresholds to create a heavily compressed signal that you can blend with the original audio.

Parallel Compressors and Parallel Setup

Parallel compressors play a crucial role in achieving a consistent output level for your processed signal.

By carefully setting up parallel compressors, you can ensure that the vast majority of your audio sources receive the same amount of compression.

This will give any modern mixes a balanced and cohesive sound.

The Importance of a Parallel Setup

Setting up a parallel compression chain correctly is crucial to achieving the desired results.

By using an aux track or bus, you can maintain separate control over the dry and compressed signals.

This allows you to fine-tune the blend and find the perfect balance for your mix.

• Wet/Dry Signals

In parallel compression, the “wet” signal refers to the compressed version of the audio, while the “dry” signal is the original, uncompressed audio.

Balancing the wet/dry signals is essential to achieving the desired effect.

It allows you to maintain the natural dynamics of the source material while adding the benefits of compression.

Tip: Start with a lower wet/dry ratio (e.g., 25% wet, 75% dry) and gradually increase the wet signal until you find the ideal balance for your mix.

Keep in mind that the perfect ratio may vary depending on the material and your desired outcome.

What Is a Compressed Signal?

The dry signal represents the original, unprocessed audio in your mix, while the compressed signal is the version that has been processed with a compressor.

When using parallel compression, it’s essential to find the right balance between these two signals to achieve the desired sound without compromising the integrity of your mix.

Parallel processing extends beyond compression and includes other techniques like

1. Parallel EQ

2. Parallel distortion

3. Parallel reverb

These methods involve blending the original, dry signal with a processed version to achieve a desired effect while preserving the natural characteristics of the source material.

Advanced Parallel Compression Techniques

Once you’ve mastered basic parallel compression methods, it’s time to move on to some more advanced techniques.

• Aux Track and Rear Bus Compression

Aux tracks and rear bus compression are advanced techniques that can further enhance your use of parallel compression.

Rear bus compression, in particular, is a variation of parallel compression that treats the stereo bus with a compressor instead of individual elements within the mix.

This technique can help glue the mix together and create a cohesive sound.

• Rear Bus, Plugins, and Lead Vocal Processing

Using rear bus compression, built-in parallel processing features in plugins, and applying parallel compression to lead vocals can create unique and powerful results.

By experimenting with different plugin settings and techniques, you can achieve a rich, full sound that adds depth and dimension to your audio tracks.

Example: Try using parallel compression on a lead vocal, followed by a touch of saturation or harmonic distortion on the compressed signal to create a warm, full-bodied vocal that cuts through the mix.

• NY Compression Technique

The New York compression technique, another name for parallel compression, is a popular method for adding punch and power to drums, bass, and other elements in a mix.

The technique involves blending a heavily compressed signal with the original audio, allowing you to maintain the natural dynamics of the source material while adding the benefits of compression.

The Mix Knob and Balancing Levels

The mix knob, found on many compressor plugins, allows you to balance the wet and dry signals (above) in parallel compression directly within the plugin.

This feature streamlines the process and makes it easier to find the perfect balance between the compressed and uncompressed signals.

Attack & Release Controls

The attack and release controls on a compressor determine how quickly the compressor responds to the input signal and how long it takes to return to its initial state.

• For drums 一 Use a fast attack and release to emphasize the transient energy and create a punchier sound.
• For vocals 一 Use medium attack and release setting to help maintain the natural dynamics while controlling the overall level.

These controls are crucial in shaping the sound of parallel compression, as they can impact the transient response and the overall character of the compressed signal.

Output Level and Source Material Considerations

When using parallel compression, it’s essential to consider the output level of the compressed signal and the characteristics of the source material.

Ensure that the compressed signal doesn’t overpower the original audio or introduce unwanted distortion or artifacts.

Production Tips & Tricks

The following production tips and tricks will help you achieve the best out of your Parallel Compression ventures.

1. Start with moderate compression settings and adjust as needed to find the sweet spot for your mix.
2. Use an aux track or bus to maintain separate control over the dry and compressed signals.
3. Experiment with different compressor plugins and settings to find the perfect combination for your mix.

Remember, like all other aspects in production, experimentation is key.

Don’t forget to play around with different parameters and techniques in order to evolve and grow.

Mistakes to Avoid

1. Over-compressing the signal, which can lead to a lifeless or distorted sound… but remember, aggressive compression is encouraged, just don’t overdo it.
2. Applying parallel compression to every element in the mix, resulting in an overly dense and cluttered mix.
3. Neglecting to fine-tune the balance between the wet and dry signals, which can diminish the natural dynamics of the source material.

Mixing Vocals

Use parallel compression to enhance a vocal track by adding presence, consistency, and power.

1. Use a medium attack and release setting to maintain the natural dynamics of the vocal performance.
2. Experiment with different compressor plugins to find the one that best suits the character of the vocals.
3. Balance the wet signals and dry signals to achieve a consistent and powerful vocal sound without sacrificing the natural dynamics.

By blending the dry vocal signal with a heavily compressed version, you can bring out the subtleties and nuances of the performance while maintaining the natural dynamics.

Example: To enhance your lead vocal track, try using a medium attack and release setting on the compressor to allow the transients to pass through while still controlling the overall level.

Play around with different wet/dry ratios to find the perfect balance for your mix.

Transforming a Drum Kit Sound
