Opus is an open, royalty-free lossy audio codec standardised by the IETF as RFC 6716. It was designed to cover everything from low-bitrate speech to full-quality stereo music in a single codec, and it consistently outperforms MP3 and AAC at the same bitrate. Opus powers voice and audio in WhatsApp, Discord, Zoom, YouTube, and every WebRTC browser call, which makes it one of the most widely used audio codecs in the world.

 

How to open an Opus file?

Every major web browser plays Opus natively, so dragging the file into a browser tab works. On the desktop, VLC media player and foobar2000 both support it out of the box.

 

Android plays Opus natively, and FFmpeg handles conversion from the command line. Some older hardware players, car stereos, and editing programs still do not recognise the format — in that case convert it with our Opus to MP3 tool. You can also convert the file with our OPUS to MP3 tool.

Initial Release: 2012


Apple developed Audio Interchange File Format (AIFF) to store high-quality, digital-audio (waveform) data. Many professionals use it, particularly users of Apple platforms. It is lossless, which means there is no loss of quality or data from the original, but this also means that AIFF files take up more space. AIFF can locate loop point data and musical notes, which is useful for musicians.

 

How to open an AIFF file?

By default, AIFF opens in Windows Media Player or iTunes, depending on the operating system. Other programs that open AIFF include VLC media player, Audacity, Winamp, and Elmedia Player.

 

Please note that if using an Android or non-Apple device, you will need to convert the AIFF file—likely to a MP3 file—in order to open it. Mobile Apple products open AIFF files without file conversion.
