AIFF to OPUS converter

The Audio Interchange File Format (AIFF) is a file format for storing high-quality audio data. It was developed by Apple Inc. in 1987 and is used commonly in the Mac OS operating system and its associated applications, though it can be found on other platforms as well. An AIFF file can store many different types of audio data, including samples taken from analog sources such as vinyl records and standard CD-quality audio.

AIFF files are uncompressed, making them larger than lossy compressed formats like MP3 and AAC -- but also providing better audio quality overall. Additionally, AIFF supports metadata tags like artist name and track title, allowing audio players to quickly identify the audio file's contents. While less common today than MP3 and other formats, AIFF still enjoys a following among audiophiles, musicians, and other audio professionals.

The OPUS file format is a widely used audio format for compressing digital audio data. It is an open, royalty-free speech and music codec that provides high-quality sound at low bit rates and is suitable for both streaming and non-streaming applications. OPUS files are based on the Ogg container format and use a variable bitrate (VBR) approach to encoding, allowing users to adjust the amount of data encoded according to their needs.

OPUS files offer support for a variety of features including multi-channel surround sound, low-delay and wide-band options, forward error correction and support for metadata such as artist, album and track names. Additionally, OPUS files can support a range of data rates from 6 to 510 kbps and can be easily opened by most modern music players.
