have traditionally been released in stereo, but there is no reason why
Dolby Surround information cannot be encoded onto CD. The beautiful
simplicity of the Dolby Surround system is the way it is matrix-encoded.
This means that if you listen to a Dolby Surround recording through
a stereo amp and speakers, you get all the information in stereo. But
if you play that same recording through a Dolby decoding amplifier connected
to additional speakers, you get that same information spatialized in
way that replicates how you would hear the recording in a cinema.
In technical terms: the Sound Punch CDs bearing the Dolby Surround logo
have been mixed into the Dolby Surround or Pro Logic matrix. This means
that from a surround sound amplifier, separate sound information is
sent discretely to the following speakers of a surround sound system:
the front left speaker;
2. the front right speaker;
3. the front centre speaker;
4. the sub woofer speaker; and
5. simultaneously through the rear left and rear right speakers, combined
as a single mono sound.
that's 5 tracks of information in place of the standard 2 tracks one
gets with stereo playback. This is not to say that more is better',
but rather that one can use these 5 tracks as spatial locations so as
to shift the sound through wide playback space. Handled effectively,
an immersive experience is generated - sometimes gratuitously trippy,
but sometimes well-suited to the more off-kilter sonic explorations
typical of the Sound Punch label.
Sound Punch started out testing and specialising in the area of surround-sound releases, and has now concentrated on releasing many of Philip's works on DVD-Rs. These audio-only discs contain the complete 5. 1 or quadraphonic mixes.
Brophy's solo CDs were recorded and produced at his own Gelatin Studio.
The Ph2 CDs were produced at Gelatin and Philip Samartzis' Beehive
Studio. The Lazy3 CD was recorded and produced at RMIT Media Arts.
The collaborative project between Philip Brophy, Francois Tetaz and
Darrin Verhagen was recorded and produced at Gelatin, P2 Facility
and Moose Mastering.
