Multiband compression has been in existence for a while now. Whilst it can be very powerful, it can also entirely ruin a mix in the wrong hands. Parallel compression has also been around for a while, and the technique can be arguably more subtle and transparent as it leaves the original signal untouched.
Leapwing Audio’s new plug-in intends to merge the two in a powerful, yet transparent dynamics tool, which will be exceptionally good at bringing up low-level detail instead of squashing dynamics. DynOne has 5-bands with fixed crossovers at 160Hz, 800Hz, 4kHz & 11kHz and new low latency mode with optimized filters.
