Abstract

The invention discloses a method and system for adding additional information to an LC3 audio code stream and a medium, and belongs to the technical field of audio encoding and decoding. The method comprises the following steps: acquiring an unused bit space in an LC3 audio coding process, including: acquiring a single-bit unused space of a current coding frame in the LC3 audio coding process, the single-bit unused space being a difference between a residual coding bit estimated length and a residual coding bit actual length of the current coding frame in the LC3 audio coding process; acquiring a multi-bit unused space of the current coding frame in the LC3 audio coding process, wherein the multi-bit unused space is an unused residual space of the current coding frame in the LC3 audio coding process; and adding additional information in the LC3 audio encoding process into the unused bit space for encoding. According to the application of the invention, extra data is transmitted through an unused bit space, so that bit waste is avoided, and the bandwidth use efficiency of encoding is improved.

Description

technical field [0001] The invention relates to the technical field of audio codec, in particular to a method, system and medium for adding additional information in LC3 audio code stream. Background technique [0002] The current mainstream Bluetooth audio codecs include: SBC audio codec, which is mandated by the A2DP protocol and is the most widely used; AAC-LC audio codec, which has better sound quality and is widely used, and is supported by many mainstream mobile phones ; aptX series audio codec, its sound quality is good, but its code rate is very high, and it is Qualcomm's unique technology, relatively closed; LDAC audio codec, its sound quality is good, but its code rate is also high, and it is Sony's unique technology is also very closed. Based on the above reasons, the Bluetooth Sig of the Bluetooth International Alliance and many manufacturers launched the LC3 audio codec, which has the advantages of lower delay, higher sound quality and coding gain, and no paten...
