Ultra-clean upward limiter
Boost’s unique, revolutionary design controls your tracks dynamics with incredibly low distortion.
Use Boost on tracks, groups and your master bus to increase levels without changing the EQ or phase.
Add Emphasis to pick out transients. Adjust the focus control to reveal low-level details with upward limiting or improve your tracks stereo image with its mid-side mode.
UrsaDSP Boost in detail
- Ultra-low distortion – incredibly transparent
- Prevent inter-sample overs
- Focus smoothly changes from upward to brick-wall limiting
- Stereo image manipulation with the mid-side mode
- Drive and emphasis modes for character
- Preserve reverb tails with the max gain control.
- Parallel compression
Example: mastering limiter This is an normalized but unmastered track (DT8 Project – Adrenochrome). Boost increases the levels but keeps the clarity.
Precise control for loudness and peak levels
With Boost, unlike other limiters, you’re not forced to smother your mix in character just to get it loud. Boost’s unique Trajectory technology keeps your audio clean and distortion free.
Or if you need character, use the Emphasis control to enhance psychoacoustic loudness of transients without increasing the peak level. So for the first time, you can control perceived loudness and peak level independently.
Example: emphasis and upward limiting A demonstration of upward limiting and emphasis in isolation and together. Listen to how emphasis enhances the attack of the kick, and how the room comes out when the upward limiter is enabled.
Eliminate clipping with true peak control
No matter how much gain reduction you apply you’ll never get any clipping.
Boost can even eliminate inter-sample overs. These cause DACs to distort, create artefacts during compression and unexpectedly trigger loudness restrictions on streaming platforms. The clarity true-peak detector* removes inter-sample overs whilst maintaining boost’s hallmark super low distortion without changing the sound of your mix.
Trajectory and the future of dynamics
Despite the invention of DSP, most plugin compressors mimic technology from 60 years ago. Some plugins have added lookahead, but still use the same basic principles with all their limitations, distorting the transients as they react.
Trajectory goes back to the original requirement – controlling audio level – and uses fresh techniques that are only possible with modern digital signal processing. Instead of forever playing catchup when the audio hits a transient, Trajectory is already allowing for it and plotting the right curve to gracefully and musically process your audio.
With Boost, you can separate volume from distortion. You’re not forced to smother your mix in character just to get it to broadcast standard levels, leaving you free to choose how your music will sound.
Example: increasing reverb Here, the bell like lead sound is enhanced using Boost as an insert effect to increase the reverb, whilst lowering it’s overall peak level.
Example: details and punchiness Boost is only applied to the drum track, quiet details and punchiness are both being enhanced.
Example: higher volume – lower peaks Focus pushes up the body of the sound so that this track has lower peak levels but higher loudness.
