Is WebRTC audio codecs known? If you’re working with WebRTC, you know that audio codecs are essential to ensure high-quality audio communication. But do you know which audio codecs are available and what their features and benefits are?
In this article, we’ll explore some of the most common WebRTC audio codecs to help you make an informed decision about which one is best for your needs.
First, let’s define what an audio codec is. An audio codec is a software or hardware component that compresses and decompresses digital audio signals. It’s like a translator between different types of digital audio formats.
When two people communicate over the Internet using WebRTC, their voices are converted into digital signals, compressed by an audio codec, transmitted over the network, and then decompressed by another codec on the receiving end so that it can be played back as sound.
Now that you have a better understanding of what an audio codec does let’s dive into some of the most popular options available for WebRTC.
KEY TAKEAWAY

The familiarity and understanding of WebRTC audio codecs may vary among individuals, and further exploration and research can help unravel the complexities and enhance knowledge in this field.
Opus Audio Codec: Features and Benefits
You’re gonna love Opus audio codec (1) because it packs a punch with its impressive features and benefits like low latency, wideband support, scalability, and more. It’s an open-source audio codec that delivers high-quality audio at low bitrates.
With Opus, you can easily transmit voice or music over the internet without compromising on the quality of the audio. One of the most significant advantages of Opus is its low latency feature. This means that there is minimal delay between when you speak and when your voice is transmitted to the other end. This makes it ideal for real-time applications like online gaming, video conferencing, and VoIP calls.
Another key benefit of Opus is its ability to support a wide range of bandwidths from 6 kbps up to 510 kbps. This makes it highly scalable and adaptable to different network conditions. Additionally, Opus has been optimized for both speech and music so that it can deliver excellent sound quality across different genres.
With all these fantastic features and benefits in mind, let’s move on to discuss another popular audio codec- G.711.
G.711 Audio Codec: Features and Benefits
One thing that might surprise you about G.711 audio codec (2) is that it’s been around for over 40 years, but it still remains a popular choice for many communication systems today. Developed by ITU-T in the late 1970s, G.711 has since become a widely used standard in telephony networks worldwide. Here are three reasons why G.711 continues to be a go-to option for audio compression:
- Compatibility: One of the biggest advantages of G.711 is its compatibility with most devices and networks, making it easy to integrate into existing communication systems without any additional equipment or software.
- Low Latency: Another key feature of G.711 is its low latency, which means that there is minimal delay between when someone speaks and when their voice is heard on the other end of the line.
- High Quality: Despite being a low-bit-rate codec (64 kbps), G.711 provides high-quality audio with very little distortion or loss of sound quality.
Moving forward, let’s take a look at another popular audio codec – G.722 – which offers even better sound quality than its predecessor while maintaining backward compatibility with G.711-based systems without requiring significant upgrades or changes to infrastructure configurations…

G.722 Audio Codec: Features and Benefits
G.722 is a codec that enhances audio quality while maintaining compatibility with G.711-based systems, allowing for seamless integration into existing communication networks.
This algorithm offers superior sound clarity, making it ideal for applications like teleconferencing and video conferencing where participants need to communicate clearly without background noise or interference.
One of the significant benefits of G.722 is its ability to operate at low bit rates while still providing high-quality audio output.
This feature makes it an excellent choice for applications that require low bandwidth usage, such as VoIP calls over the internet or mobile networks. Additionally, this codec provides improved voice recognition capabilities by preserving higher frequency ranges in speech signals.
When choosing the best audio codec for your needs, several factors should be considered, including bandwidth requirements and desired sound quality levels. It’s crucial to choose a codec that offers high-quality audio output while also being compatible with your existing communication systems.
With its excellent sound clarity and compatibility with G.711-based systems, G.722 is an excellent choice for those looking to enhance their communication network’s overall performance and user experience.

Choosing the Best Audio Codec for Your Needs
If you want to sound crystal clear and make sure your message gets across, choosing the right audio codec is like hitting the bull’s eye.
The following list will help you choose the best audio codec for your needs:
- Consider compatibility: Your choice of audio codec should be compatible with your device, platform, and software. Make sure to check if there are any limitations or requirements before choosing an audio codec.
- Look at bitrates: Different codecs have different bitrates which affect the quality of sound transmitted over a network. You need to balance between high-quality sound and low bandwidth usage when selecting an audio codec.
- Check for latency: Latency refers to the delay between sending and receiving data packets in real-time communication. Choose a codec that has low latency to ensure smooth communication without delays.
- Evaluate compression vs quality: Some codecs offer high compression rates but may compromise on sound quality while others provide better sound quality but require more bandwidth.
Choosing the right audio codec can greatly improve your communication experience by providing clearer sounds even under challenging network conditions. Keep these factors in mind when picking an audio codec that suits your needs, whether it’s for personal or professional use.
