Soft-knee compression kicks in gradually as the threshold is crossed. Hard-knee compression kicks into its full compression amount as soon as the threshold is crossed. On some audio compressors you may see the terms hard-knee and soft-knee. Hard-Knee Compression and Soft-Knee Compression You will feel more sustain from your notes with a longer release time. A short release time makes for a real squashed sound.Ī long release time will follow the note more naturally as it decays. Release is measured in milliseconds (ms).Ī short release time would mean only the attack would be compressed and the rest of the note would run its course like normal. Compression ReleaseĬompression release refers to how long the compressor is engaged after the signal exceeds the threshold. If you wanted the sound of your plucking or pick attack to come through more, you could increase the attack time to let it pass through. The bulk of a volume spike comes at the beginning, or attack, of a note. You might adjust it from 0 (engages immediately) to a few milliseconds (waits 2 to 10 ms). Compression attack refers to when the compression effect is engaged after the signal crosses the threshold. Some compressors allow you to adjust the compressor’s attack. Then slowly lower the compression amount until it suits your taste. At first you might wonder if it’s even on and working! Try starting at the highest amount of compression and you’ll hear the dynamics squashed. You really have to listen closely to adjust it. Most bass players use a 2:1 up to 5:1 compression ratio. On some effects units the ratio is just marked as ‘compression’ or ‘amount’. (Many TV sets now include limiters to squash loud commercials.) Limiters are often used to prevent damage to speakers. You may see units called compressor/limiters.
Notice in the diagram how the slope of the dynamics changes past the compression threshold.Īn ∞:1 (infinity to 1) means for any signal above the threshold sent to the compressor only 1dB comes out. That means for every 3 dB you send to the compressor beyond the threshold only 1 dB comes out. The ratio might be something like 3:1 (3 to 1). The compression ratio selects the amount of compression to apply on signals above the threshold.
It depends on if you only want really loud notes compressed or most everything compressed. If you can adjust the threshold setting on your compressor, adjust it to taste. Any signal lower than the threshold will be unaffected. Any signal passing through the compressor which is louder than the threshold setting will be compressed. The compression threshold is the volume level (gain) at which the compression effect is engaged. Compressors usually have an adjustable threshold setting.
