Fixed-point ANSI C implementation. Re-entrant implementation C-callable APIs. Operates on 16-bit PCM speech signals sampled at 8 khz (narrow-band) or 16 khz (wide-band). Lookahead delay is 5 ms for narrow-band mode and 10 ms for wide-band mode. Identifies and suppresses all types of stationary and non-stationary noises. Fast convergence and adaptation times for non-stationary noises. Provides better objective evaluation scores when compared to EVRC and Speex noise suppression algorithms. Optimized for low memory and low complexity.
