BAM is a stereo reverb processor inspired by the late 70s / early 80s digital reverberator units. These units are sought after by sound engineers, producers, and musicians for their grainy, warm, and musical reverberations. OTO Machines have carefully listened to all digital reverberators built from 1976 to 1986, studied their architecture, and read all the available papers (from 1961 to nowadays) on digital reverb design. It seemed obvious to them that the musicality of the early digital reverb processors was partly due to the algorithms (the way the processor synthesized a natural reverberation), but also to their hardware limitations. The audio signal was severely high-cut filtered (10 kHz was standard at that time) because of the limited sample clock. Some units used 12-bit gain stepping converters to achieve a 15-bit resolution and others used the first 16-bit converters. Then the samples were digitally processed through a 16 to 20-bit fixed-point CPU with limited memory. The algorithms had to be simple but efficient to create the most musical and versatile reverberation from these limitations. And the hardware itself added grain and warmness to the sound. The technology used in BAM is very close to the one used in these early digital reverberator units: 16-bit converters, 20-bit fixed-point processing, analog filtering, and even an input transformer transient simulator. Some of the 7 reverb algorithms are influenced by the early structures, and some are brand new.
