What is a Codec?
A codec, which is also referred to as a “coder-decoder,” is a software or hardware device that compresses and decompresses digital audio and video files. Its main function is to efficiently transmit and receive multimedia data. By using specific algorithms, codecs are able to reduce the size of large digital files without compromising their quality. This makes it more convenient to store, transmit, and stream media content.
Codecs are crucial for various applications such as video conferencing, streaming services, VoIP calls, and multimedia editing. They encode audio and video data into a compressed format before transmission, and then decode it at the receiving end.
There are different types of codecs available, each with its own characteristics and purposes. For VoIP calls, common audio codecs used are G711 and G729. G711 offers high-quality audio but consumes more bandwidth, whereas G729 provides lower-quality but requires less bandwidth. The choice of codec depends on factors such as network conditions, available bandwidth, and desired audio quality.
In terms of video codecs, popular options include H.264 and H.265 (also known as AVC and HEVC). H.264 is widely used for video streaming due to its good compression efficiency. On the other hand, H.265 provides higher compression rates but requires more computational power for encoding and decoding.
When selecting a codec, it’s important to consider factors such as the intended use case, available resources, compatibility with devices and platforms, and the desired balance between quality and file size.
