Method, Apparatus, and System for Processing Audio Data - A simplified explanation of the abstract
This abstract first appeared for US patent application 18344445 titled 'Method, Apparatus, and System for Processing Audio Data
Simplified Explanation
The patent application describes a method for processing an audio signal.
- The method involves receiving a bitstream that represents the audio signal.
- The bitstream is decoded to obtain information about the current frame of the audio signal.
- The method decodes the bitstream to obtain a silence insertion descriptor (SID) type for the current frame.
- The method also decodes the bitstream to obtain a low-band parameter for the current frame.
- Based on the low-band parameter, the method obtains a low-band signal for the current frame.
- Based on the SID type, the method obtains a high-band parameter for the current frame.
- Using the high-band parameter, the method obtains a high-band signal for the current frame.
- Finally, the method combines the low-band signal and the high-band signal to obtain a synthesis signal for the current frame.
Original Abstract Submitted
A method for processing an audio signal includes receiving a bitstream corresponding to the audio signal; obtaining a silence insertion descriptor (SID) type of a current frame of the audio signal by decoding the bitstream; obtaining a low-band parameter of the current frame by decoding the bitstream; obtaining a low-band signal of the current frame based on the low-band parameter; obtaining, based on the SID type of the current frame, a high-band parameter of the current frame; obtaining a high-band signal of the current frame based on the high-band parameter; and obtaining a synthesis signal of the current frame based on the low-band signal and the high-band signal.
