CODECs, a combination of “coders” and “decoders,” are semiconductor devices designed to convert data by compression and decompression mechanism. These ICs consist of digital-to-analogue converters (DACs) and analogue-to-digital converters (ADCs). Data compression allows better speeds of transmission while reducing storage space, with some devices offering 32 resolution bits. The Sigma-Delta modules include I2S, Serial, PCM, USB, SPI, and many other data interfaces.
What Are Audio Codec Interfaces?
Audio codecs are computer programs that code or decode audio’s digital streams. In the case of software, audio codecs are computer programs designed to implement various algorithms to compress and decompress digital audio data as per the given file format. The primary function of the codecs includes breaking the audio signals (high-fidelity) to optimum bit numbers without deteriorating the quality to save space for file storage and transmission.
What Are the Benefits and Features of CODECs?
These semiconductor devices offer various benefits with excellent characteristics, such as:
- They are low-power and high-quality audio codecs.
- Feature on-chip temperature measurement.
- They are highly compatible.
- They are portable and small.
- They are stable and durable.
- They are highly flexible to optimize system power dissipation.
- Offer high-quality stereo audio playback performance.
What Are the Uses of Codecs?
CODEC chips are widely found in:
- Digital communication systems
- Soundbars
- Smartphones
- Tablets
- Televisions (Flat panel)
- MP3 docking stations
- In-band audio applications
- MP3 players
- Digital cameras
- Digital video camcorders
