You may find that some audio files downloaded from streaming sites, video conferencing, VoIP software, WhatsApp, etc. are saved in .opus extension, which cannot be supported and playable on some frequently-used devices. Actually, it's a lossy audio codec primarily developed for Internet streaming. Apart from .opus extension, Opus streams can also be encapsulated in .ogg, .mkv, .webm, .mp4 and the like video container formats.
The problem is, from a technical point of view, Opus definitely has quite a few advantages, but it is a relatively new audio codec that is not as widely-used and compatible as AAC-encoded audio. Therefore, many people like you, are looking for an efficient workaround to batch convert Opus files to AAC. Now you've come to the right place.
If you're confused by FFmpeg Opus to AAC command lines, or not pleased with the conversion results from online audio converters, HD Video Converter Factory Pro will definitely float your boat, which is not only a simple video transcoder, but also a handy batch Opus to AAC converter that allows you to either convert .opus files to .aac or .m4a in batches or convert Opus steam in a video file to AAC stream.
