About FLAC files
FLAC (Free Lossless Audio Codec) is a high-quality audio format that compresses audio files without losing any sound quality, making it ideal for archiving and audiophiles. It retains all original audio data while reducing file sizes by up to 50% compared to uncompressed formats like WAV. FLAC is widely supported across devices and software, though not natively playable on some portable players. As a royalty-free open format, it's popular among music enthusiasts for preserving studio-quality recordings without the large file sizes of uncompressed audio.
About OPUS files
Opus is a versatile, open-source audio codec developed by the IETF, combining the strengths of both speech and music compression. It delivers high-quality sound at very low bitrates, making it ideal for VoIP, streaming, and real-time communication. Opus excels in dynamic bitrate adjustment and works well across a wide range of applications, from low-latency gaming chats to high-fidelity music streaming. Supported by most modern browsers, devices, and platforms, it has become a key format for internet audio.
