What is the purpose of an audio compressor?

Compressors and limiters are used to reduce dynamic range — the span between the softest and loudest sounds. Using compression can make your tracks sound more polished by controlling maximum levels and maintaining higher average loudness.

How does an audio expander work?

What do expanders do? Again, like a compressor “compresses” and a limiter “limits” the dynamic range, an expander expands it. Louder and quieter parts become relatively louder and quieter respectively. As such, it’s essentially the opposite of a compressor.

What is one of the benefits of using parallel compression?

One of the main advantages of parallel compression is that this technique can be used to considerably raise low-level signals without compromising the sonic integrity of that signal’s transient peaks.

What is the purpose of the audio?

They are responsible for turning electrical signals converted and amplified by the player and amplifier into energy used to vibrate the air to create sound waves that can be heard by the human ear.

How do you use a vocal compressor?

Dial in some heavy compression (aim for 6 dB’s of gain reduction or more). Start with an attack time of 5ms and a release of 30ms and go from there. Bring up the new aux underneath the lead vocal until it starts to increase the volume of the vocal. As soon as you notice an increase in apparent volume, stop.

What is the purpose of an expander in mixing?

What are Expanders? Expanders are helpful dynamic processing tools that increase the dynamic range of an audio signal. They are essentially the opposite of a compressor, which decreases the dynamic range of an audio signal.

When would you use an expander?

The expander is most commonly recommended when there is a crossbite between the two arches or if there’s not enough space for permanent teeth to come in correctly. It works best for children and preteens because their bones are still in a growing phase.

What is the purpose of parallel compression?

The concept behind parallel compression is that by combining a clean, unprocessed signal with a highly compressed signal, the compressed signal will have the effect of increasing low-volume information while the clean (uncompressed) signal will allow transient signals through at higher volume levels.

What is the purpose of parallel compressor?

Parallel compression uses a send and return setup similar to how you would send signal to an effects processor. It is the combination of the dry signal mixed with a compressed version. In a parallel setup, you can use heavier compression to pull more depth out of the source signal.

Do you need to compress audio?

Compression is used in music to reduce the dynamic range of signals with loud and quiet elements so that both can be heard clearly. In most sounds, the transient is the loudest moment in the signal. To hear the transients equally with the body of the sound, compression is often necessary.

How does a compressor respond to a mix?

A compressor over the mix bus will respond to any content that exceeds the threshold level, and if your mix contains a number of different elements that combine to do so in different ways, a single, fixed release setting may well not be sympathetic to all of the differently ‘shaped’ peaks that result.

How do I increase the volume of my compressor?

If you have a very quiet signal you might need to increase the gain so that the compressor works better (or down if you can’t put the threshold low enough and it’s always compressing way too much). A good rule of thumb is to increase the output according to the same amount you’re compressing, either by using the output knob or the make-up gain.

What is compressor release time and why does it matter?

It’s the time it takes for the compressor to stop compressing. Faster release times means faster recovery time for the compressor. Longer release times means it keeps the signal compressed for longer, which can result in pumping with very rhythmic signals because the audio is never allowed to go back to its initial uncompressed audio.

What makes a good variable-mu compressor?

A good variable–mu compressor has the characteristic sound quality often associated with well–designed tube equipment — that is, slight but pleasing harmonic distortion and a warmth and smoothness that is hard to find with other compressor designs.
