Generally, we don’t pay attention to any format until it can’t be played, or we have some incompatibility issues. OPUS may be the kind of unfamiliar audio format that suddenly attracted your attention. This post will guide you to know more about OPUS. Moreover, I will compare it with a more widely used format, AAC. Through OPUS vs. MP3, you can easily select your desired codec.
OPUS (Open Source Audio Codec) is a relatively new audio codec developed by the Xiph.Org Foundation in 2012. Compared to AAC and MP3, OPUS can offer high audio quality at lower bitrates. The small file sizes make OPUS ideal for reducing bandwidth consumption. Moreover, thanks to its royalty-free nature, OPUS files are free from licensing fees. That makes the audio format more preferred by developers and content creators.
OPUS has advantages in real-time communication and web-based apps. OPUS is known for its low latency. There is minimal delay between the speaker and the listener. So, OPUS can help to ensure smooth voice chat, online gaming, and video conferencing experiences. With small bandwidth usage, it offers high sound quality while minimizing delays and audio lags. The low latency, efficiency, and royalty free make OPUS an attractive option for more and more users.
AAC is an audio codec developed in the late 1990s. AAC files can offer high-fidelity sound, especially at high bitrates. They are widely adopted by many music streaming services, such as Apple Music, iTunes, YouTube, and online radio platforms. AAC can be supported by most phones, tablets, and players. It is known for its balance of quality and file size. Because most MP4 files are embedded with AAC audio tracks, that makes it a popular standard. It has been a reliable option for decades.
Compared to OPUS, AAC usually needs a higher bitrate to get the same audio quality. Moreover, some AAC files may be encoded with licensing fees. When it comes to AAC editing, more processing power is required.
One big disadvantage of OPUS is its limited compatibility. While OPUS can be accepted by many devices, it is not widely supported, like AAC or MP3. As mentioned earlier, OPUS is benefit for online communication. However, in many other aspects, like music, AAC is still a better option than it. AAC files can contain more details at high bitrates.
For different purposes, you want to make the audio conversion from OPUS to AAC, or AAC to OPUS. In general, you get two ways to convert audio using online converters or desktop programs. This part tells how to transform OPUS to AAC with these two methods separately. If you need to turn your AAC songs into OPUS, you can take similar steps.
