For Film style mixing, bits and pieces of film sound are put together from
a variety of surround formats, ranging from mono to eight channels. Very
often, there may be hundreds of audio sources that need to be mixed to-
gether and put into the right spatial image. In order to bring some order to
such a vast number of sources and formats, a concept of Stems is often
used.
A Stem is a group of sounds (i.e., audio summing buses) that belong to-
gether. Stems can be 1-channel to 8-channel wide. For example, a console
may be configured to have:
2 Stereo stems for music
3 LCR stems for simple effects
1 5.1 stem for effects
1 Stereo stem for dialog, etc.
1 8-CH stem for effects
2 Dolby Surround (4-CH) stems for predubs
The basic Stem setup is defined in the Session Configuration – the num-
ber, type and assignment of Stem buses is fixed. In the Studer D950/Vista
GC, there are controls for dynamic Stem setup and for assignments of the
related recorder tracks. In this way, the Stem setup may be changed dy-
namically as the need arises.
The restriction to the total number of Stems is the number of buses for a
certain Session Configuration. Studer D950/Vista Master, Mono Group
and/or Track buses are used to build a system of Stems (each stem consists
of a number of buses) up to a maximum of 104 Stem buses at any time.
