Elysia nvelope Mastering Edition

From the Transient Designer to a dedicated mastering version

The nvelope builds on the work of Ruben Tilgner, CEO of elysia and designer of the original Transient Designer during his time at SPL. Its major development is the Dual Band mode: rather than acting only on the entire signal, it allows you to select the frequency ranges used to process the attack and sustain.

Within this family, the nvelope Mastering Edition focuses on subtle intervention. Its +/- 5 dB gain range, additional stepped controls and precise scale make measured corrections and recalling settings easier. It retains the versatility of the nvelope while offering an ergonomics suited to the demands of mastering.

To refine the depth of a mix without disrupting its balance

This dynamics processor is aimed at mastering engineers, mixing studios and producers who want to work directly on transient behavior. It can enhance the impact of a percussive program, soften an overly pronounced attack or adjust the sustain of sounds without being limited to conventional compression.

On a stereo mix, Dual Band mode helps focus the processing on the useful frequencies and limit artifacts that may occur with wideband processing. EQ mode offers another approach: correcting the low-end foundation or brightness with two shelving filters while retaining the same working environment.

Three modes for shaping dynamics and frequency response

Full Range: direct control over the envelope

The nvelope's processing operates independently of the signal's specific level. In Full Range mode, the Attack and Sustain controls respectively reduce or accentuate the attack and sustain: turn them to the left to attenuate, and to the right to enhance. This approach avoids having to balance a series of complex settings to achieve a result.

In this mode, Freq A reduces the influence of low frequencies on the attack processing. The higher the selected frequency, the less the low frequencies influence this action. The Auto Gain function automatically compensates for significant peaks caused by strong attack enhancement, helping to limit level variations and the associated risk of distortion.

Dual Band: frequency-specific processing

Dual Band mode makes the processing more selective. Freq A sets the starting frequency for attack processing, while Freq S determines the ending frequency for sustain processing. The Attack and Sustain controls retain their attenuation or enhancement functions.

This frequency selection allows the processor's response to be matched more precisely to the musical content. It promotes a natural result when Full Range mode produces unwanted effects. Auto Gain is not available in Dual Band or EQ mode.

EQ: two shelving filters per channel

In EQ mode, the dynamics processing sections are disabled while the filter stages remain active. Freq A sets the frequency of the high-shelf filter, and Attack controls its attenuation or enhancement. Freq S determines the frequency of the low-shelf filter, while Sustain adjusts its gain. The two channels can be used as independent equalizers or operate together on a stereo signal.

Two independent or linked channels

Dual Mono operation allows different tasks to be performed on each channel, such as Dual Band processing on the left and Full Range on the right. It is also possible to connect the output of the left channel to the input of the right channel to chain two processes on a mono signal, such as equalization followed by transient shaping. In Stereo Link, both channels share the same mode for stereo processing.
