From SPL comes a highly intelligent studio tool for removing unwanted sibilants from vocal recordings in realtime during performance, or from a pre-recorded track.

A New Approach To Phase Cancelling

Many modern ‘deessing' tools employ traditional compression techniques to eliminate sibilants, often resulting in a more nasal sound to the finished vocal.

Thanks to SPL’s unique phase cancelling technology, DeEsser instead removes sibilance while letting adjacent frequencies breathe by monitoring a narrower bandwidth. This retains the vocal’s original timbre and allows the more natural character to shine.

Auto-Threshold tracking

Catering for vocalists with less consistent vocal techniques can be challenging when tracking artists live. For this purpose SPL have implemented an auto-threshold feature which ensures consistent dynamic processing throughout the performance, even during varying input levels.

Inline with SPL’s revered standard, the DeEsser combines intuitive user friendliness with exemplary sonic performance and lends surgical sibilant intelligence to any mix.
