Oxford TransMod - HDX: Transient Shaper Plugin by Sonnox

TransMod is built around attack shaping. You can harden or soften transients, which is useful for adding punch to kicks and snares or taming harsh percussive hits. The 24dB range covers both gentle corrections and aggressive reshaping.

The harmonic enrichment control adds perceived loudness and presence. According to Sonnox, it allows peaks up to 6dB above digital maximum without clipping, which matters when pushing a drum bus or a dense mix.

The room ambience control can increase or reduce the effect of reverb and room sound on a recording, giving you a way to adjust the space around a source. The developer also notes that it can achieve a gated, overdriven drum kit sound quickly.

TransMod suits engineers who need focused, technical transient work on individual tracks. Sonnox describes Oxford Envolution as the broader, more creative option, with frequency-dependent control over both transient and sustain sections. TransMod is the narrower tool, meant for surgical enhancement or suppression of transients without changing the overall character of the sound.

This makes it a fit for mixing and tracking work where you want to fine-tune attacks on acoustic instruments, drums or bass. The HDX version is intended for Avid HDX systems, where processing runs on DSP so the host CPU is not taxed. Sonnox states there is no difference in sound quality between the Standard and HDX versions.
