The Gammatone filter is the most widely used auditory filter because of it’s impulse response is similar to Basilar membrane response. Using stochastic computation, a power and area hungry multiplier used in a digital filter is replaced by a simple logic gate leading to an area efficient hardware. However, a straight forward implementation of the stochastic Gammatone filter has a small value of a filter gain. To improve the performance, gain balancing techniques are used. Gammatone filter was designed using stochastic computations and Gain Balancing Techniques i.e., Globally Gain Balancing Technique and Locally Gain Balancing technique based on L-Infinity norm which leads to huge reduction of area. Filter designed and analyzed using two cascaded fourth order sections achieves an even more area reduction of 21.1% in comparison with a four cascaded second order sections of IIR filter. The design and analysis are performed in Xilinx System Generator.
