Reverb Introduction:

The TC Reverb Palette
Until 10 years ago digital reverb was mostly used as a Generic effect applied to many sources of a mix. Nowadays where more aux send and returns are at disposal new approaches have emerged. Elements of the mix are being treated individually adding room character flavor and depth in more creative and complex ways.

At TC we call this a Source based approach and we have put more than 30 man-years of development time into design and refinement of Source based room simulation.

When Generic digital reverbs were invented they stretched the DSP power and memory bandwidth capabilities of their time; and Source specific processing was completely out of the question. Even though we may now consider Generic types to be less than ideal they still have applications for which they may be chosen instead of their Source based cousins.

The large reverb and room simulation palette of High-end reverbs by TC Electronic allows the user to choose whatever principle suits the present need.

Generic Reverb
Generic reverb is primarily a flattering sustain effect which can be added to many sources of a mix or a complete stereo or multichannel stem. It adds little character but also does no harm because the effect is blurred or washed out.

If Early Reflections are offered there are only few of them and they play a rudimentary role. Therefore a strong localization is not imposed on the signal which is what you want when one reverb is used on many sources.
For a graphical artist the equivalent tool to Generic reverb would be a paintbrush.

Generic Reverb Pros
1st choice for composite mixed material and stems
1st choice when used with multichannel joystick on console or DAW
1st choice for adding to classical main microphone pick-up
Works well on moving sources
Prettier than life
Quick and easy to use

Generic Reverb Cons
Blurring takes away character from individual sources
Pitch modulation may be a problem with some material
Mono compatibility often compromised to obtain extra width
Imaging inferior to Source based reverb

Source Reverb
When elements of a mix are picked up individually a chance exists to define exactly how each of them is to be heard. There is no reason to apply one Generic reverb to several single sources unless they are supposed to present an identical position to the final listener or if you run out of aux sends.

When it is desirable to distinguish between single elements sharing more or less the same panning position source based reverb should be a first choice. Subtle discrimination between reflection patterns of individual sources can make all the difference in the world when it comes to obtaining depth expression and natural imaging.

Source Reverbs are able to generate multiple complex Early Reflection patterns. For best results if a microphone already picks up some reflections they should be excluded from the simulated pattern by using the appropriate reflection decrease control.

Instruments or sources can alternatively share the same reverb input in groups e.g. stage left center and right for a more complex and desirable result than a Generic one-send reverb approach.
For a graphical artist the equivalent tool to Source reverb would be a 3D rendering system or Virtual Studio.

Source Reverb Pros
1st choice when input sources can be separated
1st choice with spot microphones
More depth and distinction obtainable in a mix
Adds character and definition to a source

Source Reverb Cons
Require more sends or direct feeds than Generic Reverb types
No advantage on composite signals
Not ideal for moving sources
