Framing method and apparatus

摘要

A framing method and apparatus are disclosed to overcome inconsistency of gains between sub-frames caused by simple average framing in the prior art. The method includes: obtaining the Linear Prediction Coding (LPC) order and the pitch of the signal; removing the samples inapplicable to Long-Term Prediction (LTP) synthesis according to the LPC prediction order and the pitch; and splitting the remaining samples of the signal into several sub-frames. The technical solution under the present invention is applicable to the multimedia speech coding field.

1. A framing method performed by a framing apparatus including a non-transitory computer readable medium encoded to perform the operation comprising:
obtaining, by at least a part of hardware-based processing module, a Linear Prediction Coding (LPC) prediction order and a pitch of a speech signal, wherein the speech signal is frame based; removing, by said at least a part of hardware-based processing module, samples of the speech signal that are inapplicable to Long Term Prediction (LTP) synthesis according to the LPC prediction order and the pitch; and splitting, by said at least a part of hardware-based processing module, remaining samples of the speech signal into several sub-frames.
