Audio Codecs

Audio codecs are hardware or software components used to encode and decode digital audio signals. They are commonly used in a variety of applications, such as music production, voice communication, and digital audio broadcasting.

Audio codecs typically use a mathematical algorithm to convert analog audio signals into digital form, and vice versa. They can also compress and decompress digital audio signals to reduce their size and increase transmission efficiency.

Some common types of audio codecs include:

1. Pulse Code Modulation (PCM): This is a standard method of digitally representing analog audio signals. It samples the audio signal at regular intervals and records the amplitude of each sample as a binary number.

2. Adaptive Differential Pulse Code Modulation (ADPCM): This is a type of audio compression that reduces the size of digital audio files by removing redundant information. It achieves this by recording only the differences between adjacent samples, rather than recording each sample individually.

3. MPEG Audio Codecs: These are a family of audio compression algorithms developed by the Moving Picture Experts Group. They are commonly used in digital audio broadcasting and music production.

4. Dolby Digital: This is a popular audio codec used for home theater and digital television systems. It provides high-quality surround sound and is commonly used in DVD and Blu-ray discs.
