Why Audio Compression Is Essential For Online Video Streaming?
Every person has a tendency to talk about video and how it is delivered to the end audience, but the audio is equally important in online video streaming. One cannot ignore the quality of audio and the space that it carries while delivering online video content to the end audience. The audio codec comes as quite an essential need to get high-quality audio in the least space. In order to get the best quality of online streaming, you need to choose the audio codec wisely that suits and fulfills the need for quality of experience. With the information, you will be able to make the right choice for video content delivery.
The term codec is made from the two terms “coder” and “decoder”. It is a tool to encode and decode multimedia files and make them easier to distribute with the use of the codec. It is used for video and audio compression in video streaming over the internet. Today we will try to understand the importance of audio codec. A software-based codec for audio comprises od algorithms that help in coding and decoding the audio while a hardware-based codec is fundamentally for analog audio data to be encoded or decoded. It is also named a sound codec.
It is used for reducing the size of the audio file without affecting the quality of the sound. The central purpose of using an audio codec is to store high-quality audio signals while occupying the least space possible. The quality of the audio is restored by decoding the compressed audio file with the same codec just before the playback. This process not only reduces the storage need but also decreases the bandwidth requirement for the transmission of the content. With the use of codecs, it becomes easier to make the delivery of the streaming content seamlessly.
In a time where speed matters a lot, latency make reduces the viewership of the platform. If not used properly, there are changes that the viewers make to leave the platform and go for another one.

Google Releases Lyra V2: A New Audio Codec
Google has recently released a new codec named Lyra V2, a better, faster, and more versatile speech Codec. The architecture of the new Lyra V2 brings scalable bitrate capabilities, provides better performance, provides wider platform support and generates a higher audio quality. With the release of Lyra V2, Google is trying to evolve with the community.
The Architecture Of Lyra V2
The latest release of the Lyra V2 is based on SoundStream, an end-to-end neutral audio codec. The architecture of the latest audio codec includes a residual vector quantizer Or RVQ which is present before and after the channel of transmission. RVQ quantizes the encoded content into a bit stream and thereafter reconstructs it at the decoder side.
This integration of RVQ into the codec infrastructure allows changing the bitrate of Lyra V2 at any time just by selecting the number of quantizers to use. To generate higher-quality audio more quantizers are used. This codec uses three different bitrates which include 3.2 kbps, 6 kbps, and 9.2 kbps which enables the developers to choose bitrates suitable for network conditions and other requirements. With this new architecture, the delay in the audio delivery is reduced from 100 ms from the previous version. It is most comparable to the most used codec Opus which has an approximate delay of 26.5 ms, 46.5 ms, and 66.5 ms.
This latest audio codec released by Google has the ability to encode and decode audio by 5x than the previous version. Apart from the speed and performance, the quality of the audio generated by this new audio codec has also improved. This model of V2 is exported in TensorFlow Lite. All this makes V2 a great alternative to other state-of-the-art audio codecs. It has the ability to be connected with more devices in bandwidth-constrained environments, making it an appropriate choice for higher audio quality requirements.
