Original Abstract Submitted
aspects of the present disclosure provide improved techniques for coding audio signal with a transient audio sound. improved techniques include parsing a frame of predetermined length of audio samples into a series of windows of a smaller size, and transforming the windows of time-domain samples into a series of windows of frequency-domain samples. in an aspect coding of the frequency-domain samples may include vector quantization of vectors formed of frequency-domain samples selected from across the frame.
