Part 3. FAQs about Audio Compressors Online

What is an audio compressor?

An audio compressor, in the context of software, is a digital tool used for controlling the dynamic range of audio signals in various audio production and editing applications. It works similarly to hardware compressors but within a digital environment. Audio compression software allows you to adjust the loudness and dynamics of audio by reducing the volume of louder portions while boosting quieter parts.

What are the best settings for an audio compressor?

The ideal settings for an audio compressor can vary depending on the specific audio source and the desired effect, but here are some general guidelines. Threshold: Set the threshold to determine when compression starts. It's usually adjusted to match the level of the audio source. Ratio: Common ratios are 2:1, 4:1, or 8:1. A 4:1 ratio is often a good starting point for gentle compression. Attack Time: Adjust the attack time to determine how quickly the compressor responds to levels exceeding the threshold. For vocals, a medium attack time of 10-30 milliseconds is a reasonable starting point. Release Time: The release time controls how long the compressor takes to stop reducing gain after the audio level falls below the threshold. For vocals, a release time of 100-300 milliseconds is typical. Makeup Gain: After compression, you may need to add makeup gain to restore the lost volume and achieve the desired output level.

What is the difference between a compressor and a limiter?

A software compressor is designed to control the dynamic range of audio signals by gently attenuating the volume of sounds that exceed a set threshold. It allows for a more nuanced and gradual reduction in gain, which can be useful for dynamic control and shaping the sound. A software limiter, on the other hand, is a more heavy-handed tool that's primarily used to prevent audio signals from exceeding a specific maximum level, known as the ceiling.


Those are the audio file compressors you may utilize. Online tools should help you when you don't want to download software to your PC. On the other hand, desktop programs are there to help you compress audio files even without access to the internet and get the best out of your audio files.
