XII. ACOUSTIC PORTRAIT
Allen Organs are the only digital organs to bring the science of sampling to acoustics! Ordinary
electronic reverb is a synthetic imitation of acoustics “applied to” the sound, not created as an
integral part of it. Acoustic Portrait™ produces the real thing in exacting detail!
Acoustic Portrait™ begins with a sampling process using impulse responses that measure an actual
room’s acoustic properties. These measurements are then stored in the organ's computer memory.
Through an advanced real-time mathematical process called “convolution”, the acoustics of the
sampled room actually become an integral part of the organ’s sound, producing a noticeably
smoother, more natural result than synthetic reverb. Allen engineers have recorded the acoustics of
cathedrals and other acoustically desirable buildings throughout the world. With advanced
processors (DSP) and patented low-latency convolution algorithms, Acoustic Portrait™ reproduces
the true acoustic response of each original room with stunning realism! Each organ equipped with
Acoustic Portrait™ features 10 different Acoustic Portrait selections, ranging from intimate rooms to
cavernous cathedrals.
Available Reverb Selections:
1. Pipe Chamber
2. Small Theatre
3. Small Church
4. Medium Room 1
5. Medium Room 2
6. Medium Room 3
7. Large Room 1
8. Large Room 2
9. Cathedral
10. Large Cathedral
Acoustic Portrait is controlled within the GeniSys™ Display and must be turned ON to hear the
selected reverb selection. The Acoustic Portrait
selection as well as the gain (volume), measured in
dB (decibels), can be accessed and adjusted within the GeniSys™ Display.
