If you’re in the world of audio and video, you may have come across the term “codec”. But what exactly is it? A codec is a hardware circuit that converts analogue signals to digital data while compressing the digital data into less space using software or hardware.
Most Popular Speech Codecs
Here are some of the most popular speech codecs:
- G.711 – A low-bandwidth codec that’s popular in VoIP (Voice over Internet Protocol) systems.
- G.729 – A high-compression codec that’s also great for VoIP systems.
- Opus – A codec that’s known for its high-quality voice transmission and low latency.
- AMR (Adaptive Multi-Rate) – A codec that’s commonly used for mobile phone voice calls.
Specialist Speech Codecs
Speech codecs are a specialized type of audio codec that’s designed to search for linguistic and acoustic patterns. This type of codec can achieve the highest voice compression because the human voice has a smaller audio range than music.
