TRANSIENT SPEECH SIGNAL ENCODING METHOD AND DEVICE, DECODING METHOD AND DEVICE, PROCESSING SYSTEM AND COMPUTER-READABLE STORAGE MEDIUM |
摘要 |
<p>A transient signal encoding method and device, decoding method and device, and processing system are provided. The transient signal encoding method includes: obtaining a reference sub-frame where a maximal time envelope having a maximal amplitude value is located from time envelopes of all sub-frames of an input transient signal (11); adjusting an amplitude value of the time envelope of each sub-frame before the reference sub-frame in such a way that a first difference is greater than a preset first threshold, in which the first difference is a difference between the amplitude value of the time envelope of each sub-frame before the reference sub-frame and the amplitude value of the maximal time envelope (13); and writing the adjusted time envelope into bitstream (15).</p> |
