"s Rhythm™ SA3229 hybrid is a trimmer-configurable DSP system based on a four-channel compression circuit featuring a feedback cancellation algorithm. Based on a phase cancellation method, Rhythm SA3229"s adaptive feedback reduction algorithm provides added stable gain to enable extra gain and user comfort. It features rapid adjustment for dynamic feedback situations and resistance to tonal inputs. In addition to these adaptive algorithms, Rhythm SA3229 also supports the following features: up to four channel WDRC, low-distortion compression limiting, cross fading between audio paths for click-free memory changes, eight-band graphic equalizer, eight configurable generic biquad filters, programming speed enhancements, in-channel squelch to attenuate microphone and circuit noise in quiet environments, optional peak clipping, flexible compression adjustments, volume control, rocker switch, noise generation for tinnitus treatment, and industry-leading security features to avoid cloning and software piracy. A trimmer interface supports manual circuit configuration. It continuously monitors trimmer positions and translates them into the hearing-aid parameters of choice. A serial data or I²C interface provides full programmability at the factory and in the field. RHYTHM SA3229 is a single-chip hybrid with a One-Time Programmable OTP memory that is intended for low cost applications requiring high gain.ARK is a set of software building blocks that can help reduce the time it takes to develop hearing aid fitting software.
