Opus Codec.
No, it’s not a spell like hocus pocus. It is actually something you use everyday! To best explain it in layman’s terms, let’s start with some definitions.
Codec: a device or computer program used to encode or decode a digital data stream or signal. (digital signal / language)
Audio Codec: also known as a ‘sound codec’ is a codec that encodes or decodes audio.
Opus: an audio coding format
Now that we have the definitions, lets tie them together in an example.
When you go on YouTube and watch a video, Codec is working behind the scenes. If you do not have a strong internet connection, YouTube is going to deliver your video in the best possible quality. The graphic display resolution will depend on what your internet connection can handle. However, the quality of the audio will not be affected. Even though you have a low quality resolution video, you will still have good quality audio. The worse the internet connection, the smaller the codec needed.
YouTube engages with your internet capabilities and chooses the best resolution for you. Audio quality is a little bit different. Desk phones communicate with different codecs and Opus is an audio codec for phones. Opus Codec is capable of handling a wide range of audio applications like VoIP and video conferencing.
Another example to explain how Opus Codec works:
Say you are in a hotel. Often, the wifi in a hotel is slow, unstable or has a weak signal because so many consumers are sharing it. You are grasping for a good connection to make a phone call through your VoIP phone or UC application. Opus Codec is able to optimize the audio codec with the given bandwidth to provide the best call experience possible with the resources you have.
Sometimes audio on a mobile device is good and then bad and then the call drops. Opus is smart and does what YouTube does and adjusts the audio quality instead of dropping the call. It automatically adjusts based on the network, service range and other factors affecting the connection.
Another example would be talking on Bluetooth in a car. If you are driving at a fast speed, if it is raining or windy outside, or if there are other outside noises affecting your ability to hear, your Bluetooth will adjust the audio for you. Opus will help when you’re driving and will shift from one tower to another to ensure the best quality of your network connection. It will change minute by minute, without you knowing, and will adapt to give you the best possible quality for your current situation. Unfortunately, it can’t help with back seat drivers.
Opus Codec is very smart and adaptive to what your internet’s capabilities are. It gives you the best possible outcome for what you are capable of. This automatic adjustment is something that often goes unnoticed or taken for granted.
Although the concept is relatively new for the telecommunication industry, Opus Codec is a feature found in Bicom Systems PBXware and gloCOM version 5.2. Bicom Systems seeks to provide the best products for our customers. Poor audio quality is not considered ‘the best’.
