Embodiment Construction
[0031] In order to solve the problem that the existing embedded speech coding standards can process narrow signal frequency bands and are not suitable for coding audio signals, the embodiments of the present invention provide an embedded speech or audio signal coding and decoding method and device.
[0032] Such as figure 1 As shown, the embedded voice or audio signal coding method provided by the embodiment of the present invention includes:
[0033] Step 101, divide the signal into low-frequency sub-bands and high-frequency sub-bands according to the frequency band occupied by monophonic ultra-wideband speech or audio signals;
[0034] Step 102, at the broadband embedded coding layer, perform embedded coding on the low-frequency sub-band signal of the monophonic ultra-wideband speech or audio signal;
[0035] Step 103, perform embedded coding on the high-frequency sub-band signal of the monophonic ultra-wideband voice or audio signal at a preset high-frequency signal coding...
