The WMA extension is a proprietary audio file compressed using Windows Media Compression. It is a proprietary format developed by Microsoft. This file is both an audio codec and an audio format. This file format was created by Windows to compete with other popular compressed audio formats. We must pay tribute to Microsoft: using their virtually unlimited resources, they have achieved the implementation of support for their brainchild in almost all hardware and software players. Microsoft has implemented support for DRM in WMA, a digital copyright management system that allows you to sell protected songs using special services. There are many WMA sub-formats, including WMA Pro, a lossy codec that supports high-resolution audio; WMA Lossless, a lossless codec that compresses audio without losing quality; and WMA Voice, a lossy codec designed for applications that support voice playback.
OPUS file is an audio file created in the Opus format, a lossy audio format designed for streaming on the Internet. It uses both SILK (used by Skype) and CELT (from Xiph.Org) codecs and supports variable bit rates from 6 kbps to 510 kbps. Opus is a completely open source, royalty-free, highly versatile audio codec. Opus is good for streaming both speech and music over the Internet. The Opus codec is used for Voice over IP (VoIP), video conferencing, in-game chat. The Opus format is supported by various software, including the TeamSpeak VoIP application, the Mozilla Firefox browser, the GStreamer framework, and the VLC media player. The main advantages of OPUS are the high audio quality and good compression achieved through dynamic adaptive streaming.
