Audio should be compressed when you want to reduce the file size without significant loss in quality. Compression can be useful when transferring or storing audio files, especially in situations where bandwidth or storage capacity is limited.
Detailed answer question
Audio compression is a technique used to reduce the file size of audio data without significant loss in quality. It is particularly useful in situations where bandwidth or storage capacity is limited, such as when transferring or storing audio files. However, the decision on when to compress audio depends on various factors, including the purpose, desired quality, and the available resources.
Compressing audio files is advantageous when the reduction in size outweighs the potential loss in audio quality. This allows for more efficient data transfer and storage. For instance, when transmitting audio over the internet, compression helps to minimize buffering times and ensures smoother playback.
One interesting fact about audio compression is its widespread usage in the music industry. With the advent of digital music formats and the rise of online music streaming platforms, the ability to compress audio files while maintaining an acceptable level of quality became crucial. This enabled the easier distribution and consumption of music, revolutionizing the industry.
Another fascinating aspect of audio compression is the various compression algorithms available. One of the most popular algorithms is the MP3 (MPEG-1 Audio Layer III) format, which revolutionized digital audio and allowed for significant file size reduction while maintaining reasonable audio quality. The development of the MP3 format was a game-changer, providing a balance between file size and audio fidelity, leading to the widespread adoption of portable music players and digital music downloads.
Here’s a table providing a comparison of different audio compression formats:
| Format | Compression Ratio | Quality |
|---|---|---|
| MP3 | High | Good |
| AAC | High | Excellent |
| FLAC | Moderate | Lossless |
| ALAC | Moderate | Lossless |
| OGG Vorbis | Moderate | Good |
To add a quote on the subject, we have the following statement by Karlheinz Brandenburg, the German electrical engineer who was one of the key inventors of the MP3 format: “MP3 compresses audio in a way that is hardly noticeable to the average listener but is capable of saving large amounts of disk space with acceptable audio quality.”
In conclusion, audio compression is a valuable technique used to reduce file size without significant compromise in audio quality. It plays a crucial role in managing limited resources, enabling efficient audio transmission and storage. Through various compression algorithms like MP3, the music industry has been shaped, allowing for the widespread distribution and consumption of digital audio. The choice to compress audio depends on factors like purpose, desired quality, and available resources, ensuring a balance between efficient utilization and acceptable fidelity.
Watch a video on the subject
This YouTube video explains that compression is about reducing the peaks or highest levels of sound when they go past a certain level called the “threshold.” A compressor decreases volume automatically, and by adjusting parameters such as attack, release, and ratio, one can control how quickly volume changes. The video discusses other features such as lookahead, knee, peak, and RMS that adjust sensitivity options and add an “expander” to reverse effects. However, the video emphasizes that the most important thing is to trust your sound and forget about any rules or book values.

You should compress an audio signal whenever you’re trying to reduce the dynamic range of a piece of audio. Dynamic range compression shortens the distance between the highest and lowest amplitude across a signal chain, creating a more balanced, consistent sound.
When to Use Compression in Your Mix (3 Situations)
- 1. When Transients Are Sticking Out of Your Mix The most basic use for a compressor involves taming transient material using downwards compression. Perhaps your snare track “bites” too hard, or the bass you’re processing has too much “slap.”
- 2. When Your Mix Isn’t Transient Enough

Should you always compress audio?
The answer is: Compression is a highly important audio effect to understand because it regularly touches every aspect of digital music creation, from sound design to mixing and mastering. It can be used in creative and musical ways, but it can also turn a dynamic and exciting mix into a flat and fatiguing one if used irresponsibly.
What tracks should be compressed?
You should not compress every track in your song automatically. Compression should be applied to tracks that have a large difference in volume between the loudest and quietest parts. It can also be used to add energy to a track. It is perfectly acceptable to have a track with no compression on it.
In this manner, How and when to use a compressor? We usually use a compressor to catch the louder peaks and make the track more consistent in volume. So we adjust the threshold until the compressor only kicks in when our recording hits those peaks. On the other hand, if we set our threshold too high, the compressor won’t do anything at all!
Is compressed audio better? Response will be: Compressing audio evens the dynamic range between the loudest and softest parts in the mix. It narrows out the levels and, by doing so, allows the audio to sit more comfortably in the final mix without extreme peaks. Leveling out the loud and quiet parts of the mix allows both to be heard more clearly.
Likewise, What is audio compression & how does it work?
Audio compression allows us tocontrol the dynamic range —the difference between the loudest and the quietest moments of a signal—by reducing its level when it rises above a specified threshold. There is a common misconception in audio that compression is a tool used in mixing to make things louder, when in reality it makes things quieter.
How much compression do you use in music? One of the most common uses of compression in music is to level out the overall dynamic range of a performance by bringing down the louder moments to in turn bring up the quieter moments in order for it to sit better in the mix. In this scenario I normally want to apply gentle, transparent compression withabout 3–6 dB of gain reduction.
Do I need to apply compression to every track? Answer to this: Apply compression as needed to help limit the dynamic range of tracks that have a large difference in volume between the quietest and loudest parts. However, because you’ll be using compression frequently and liberally, this does not mean you should automatically apply compression to every track. What Does A Compressor Do? What Is A Compressor?
Correspondingly, What Compressor settings should I use for my digital audio workstation?
Please take these compressor settings with a heavy grain of salt because each compressor is unique in its design and functionality. The stock compressor that comes with your digital audio workstation (DAW) is probably excellent for general compression purposes.

Additionally, Do you compress after the mix?
Answer to this: It is said that you do compression after the mix. Don’t you compress during the mix like on individual instruments e.g. drums, bass etc? Absolutely. Compression is the best way to control dynamics and keep some instruments in check while making other elements of the mix tighter and more powerful.
