SBC (Subband Coding)

To understand SBC (Subband Coding) with its sub-sections, let’s dive into its explanation first. We’ll then explore the advantages and disadvantages of SBC.

Explanation of SBC codec

SBC, or Subband Coding, is a digital audio compression technique. It divides the audio signal into multiple subbands. Each subband has its own frequency range. These are analyzed and compressed separately. This lets you store and transmit audio data while keeping sound quality good.

Let’s look at the table:

Subband Frequency Range Bit Allocation
1 20 – 60 Hz 8
2 60 – 200 Hz 4
3 200 – 600 Hz 4
4 600 – 2000 Hz 2

Subband 1 covers 20 – 60 Hz. Subband 2 is 60 – 200 Hz. And so on.
The bit allocation column shows how many bits are assigned to each subband for compression. Fewer bits for less important frequencies. More bits for crucial aspects.

SBC was first introduced in the late 1970s. Researchers at Bell Labs did the research. Over time, SBC got better. It now compresses audio efficiently, without losing quality. It’s used in music streaming and wireless communication systems.

SBC has been around for a long time. Its efficiency and quality make it essential for lots of technologies we use every day. Who needs a therapist when you have SBC?
