Mix: Working With Compression (1)

 

 

Acoustic instruments, electric instruments, synthesizers, sound modules, and human voices all have different dynamic ranges. When they are put together in the service of making a record, there must be some way of getting the different elements to work together. Compressors are useful processors that help control dynamic range and in so doing, allow the creative engineer or producer to put together very different audio elements into a cohesive whole.

 

By adjusting the relative dynamic ranges (not the same as levels) of the various elements inside a mix, you can alter the impact that they will have on the overall mix.

 

 

*Follow the instructions to catch up the effects of compression in a mix:

 

1) Load in "Your Song" on your DAW (e.g. Logic Pro, Pro Tools, Cubase, Ableton, etc.).

 

2) Select any instrument track (e.g. Acoustic guitar, Bass guitar, Drums, etc.).

 

3) Press "Solo" button in the instrument track.

 

4) Insert a compressor on the instrument track.

 

5) Set the compression ratio to 6:1.

 

6) Set the compressor threshold at about -10 dB.

 

7) Press "PLAY"

 

8) Set the output gain in the compressor to compensate for volume loss due to gain reduction.

Turn the compressor 'On' and 'Off' to compare the processed and unprocessed volumes - they should be roughly the same.

 

9) Compare the compressed and uncompressed signals.

Turn the compressor 'On' and 'Off' and make note of the changes in sound.

 

Do you notice any change in the track's ADSR volume envelope? Does any portion of the sound get accentuated or diminished? Write down your impressions of the compressor's effect on the instrument's volume envelope.

Attack (example) faster 
Decay (example) faster
Sustain (example) longer
Release (example) shorter

 

10) Adjust the attack time.

Sweep the attack-time controls from a fast setting (0 - 10 ms) to a slow one (30 ms and up). Compare the sound of the two settings and make notes of your impressions in the chart provided below.

 

11) Adjust the release time.

Sweep the release-time controls from a fast setting (0 - 10 ms) to a slow one (30 ms and up). Compare the sound of the two settings and make notes of your impressions in the chart provided below.

 

12) Press "STOP" and "REW" to return to the top of your song.

 

13) Apply compression and make notes on the other instruments tracks.

Repeat steps 2 through 12 on these other instrument channels.

 

*A sample chart for working with compression

  Acoustic guitar Bass guitar Vocals Drum set
Fast attack (sample) more purcussive      
Slow attack (sample) even and cleaner sound       
Fast release (sample) short, hollow      
Slow release (sample) mellow
