This article aims to present a development of reduced-delay finite impulse response digital filters with amplitude requirements using equiripple passband, peak constrained least squares stopbands, and nearly constant group delay in passband for real-time applications. The filter length, passband and stopband frequencies, ripples, and attenuation are specified for realizations. The obtained results of realized filters have group delays with a reduction of about 12-22% in passband compared to the existing linear phase finite impulse response filters for audio applications.
