elysia has released the niveau filter section of the mpressor as a free plug-in. The niveau filter plug-in is designed for changing the overall sonic character of a signal. It features two comprehensive controllers and is said to be capable of producing convincing results quickly. elysia states that whenever a classic shelving filter would be too limited and a fully parametric filter would be too much, the niveau filter is a worthwhile alternative.
Its main function is to change the proportions between high and low frequencies. elysia says the principle is “quite similar” to a pair of scales: Dependent on the gain setting around a variable center frequency, the high frequencies are boosted whereas the low frequencies are attenuated (or vice versa) at the same time.
When the x10 switch is activated, the center frequency can be shifted continuously between 26 Hz and 2.2 kHz or between 260 Hz and 22 kHz, respectively. The characteristics of the filter change in the extreme positions of the EQ Gain controller: the fully counter-clockwise setting will produce a lowpass filter, and the fully clockwise position will result in a highpass filter.
The niveau filter plug-in is available in RTAS, VST and Audio Units formats with installers for Mac OS and Microsoft Windows. It is available for download for free from the manufacturer’s Website at www.elysia.com.
