What BassShaper does
Rather than leveling a whole bass track with one compressor, BassShaper works on specific parts of the sound. The Punch knob targets only the transient-heavy portions of a bass line and applies compression or expansion to the initial attack, while the Fade control works inversely, compressing or expanding only the tail. Together they can shorten long bass notes and lengthen short ones.
Two processing sections address muddiness and boominess. Deboom is activated by amplitude and tames boominess, resulting in a cleaner tone. Demud uses a pitch tracking system to dynamically reduce the muddiness caused by the bass, following the note as it changes. The developer contrasts this with traditional bass-riding plugins that crudely alter volume.
The plugin is offered as AAX for Windows and macOS in 64-bit builds, and the developer lists native support for Apple Silicon. A trial is available. The name is shared with the developer’s sister plugin Kickshaper, but the algorithm is different and was designed specifically for bass information.
Key features
- Punch and Fade transient control. Punch applies precise compression or expansion only to transient-heavy bass material, while Fade works on the tail of each note. The two controls split note attack and decay so each can be shaped separately.
- Deboom and Demud tone correction. Deboom reduces boominess and Demud dynamically reduces muddiness using pitch tracking. Both act on specific frequency problems instead of the full bass signal.
- Level control. Level is driven by a pink noise signal and adjusts bass loudness more evenly than a standard volume rider, according to the developer.
- AB comparison and undo/redo. AB comparison and undo/redo let two settings be compared against each other while shaping a sound.
Use cases
- Taming a muddy bass line. Demud and Deboom are the controls the developer describes for reducing muddiness and boominess in a bass track.
- Shaping 808 attacks and tails. Punch and Fade separate the attack from the tail of each note, which suits the flabby 808 problem the developer describes.
Compatibility
