Specifications

Main processes using regular stereo signal scheme and it is the only available mode for multi-channels operations.

Center engages internal MS encoder and processes only the Mid channel. After processing the sound is decoded back to

stereo.

Since the M channel usually features more enregy than the S channel, this mode allows to easily control the impact of the

sound.

Stereo engages internal MS encoder and processes only the Side channel. After processing the sound is decoded back to

stereo.

Since the S channel contains the spatial information, this mode allows to easily control the stereo imaging.

MS Width Control (59)

Unit: dB - Value Range: -6 / +6 - Step: 0.01

Default Value: 0

Sets the stereo width of the processed signal. A -6 dB value deceases the stereo width. A +6 dB value increases the

wideness of the stereo mix but can produce phase issue.

MS Mode On/Off (60)

Default Value: Off

Enables one MS encoding matrix at the input and one MS decoding matrix at the output of the dynamic processing in order

to control the stereo width of the mix. When engaged, the side chain is fed by a MS encoded signal that is reflected in the

display section. The M channel corresponds to the normal left channel. And the S channel corresponds to the normal right

channel This feature is only available when two channels (no more, no less) are processed.

Delay (50)

Unit: ms - Value Range: 0 to 566.89 ms

Default Value: 0 ms

A delay reflecting the attack time can be introduced into the signal path in order to produce a zero attack time for the

dynamic processing. Shifting the delay value from the attack time allows to control transients. A delay value inferior to the

attack value lets peaks untouched by the processing.

Note that the different delay values of every band are automatically compensated. Alchemist can't be used to produce delay

based special effects.

Warning: Morphing between presets with different delay values produces sound artefacts.

Of course this delay introduces latency in the processing.

Auto Delay (49)

Default Value: Off

When enabled, the delay value is linked to the attack value. Be aware that the latency introduced by this function is now

equal to your attack time.

Warning: The latency introduced by this function equals the Attack time plus 1.35 ms @ 48 KHz.
