🎧 WAV vs FLAC – Complete Comparison (2025)
Learn the difference between WAV and FLAC audio formats: sound quality, file size, metadata, and best use cases for your music or blog.
🔹 What is WAV?
WAV (Waveform Audio File Format) is an uncompressed audio format created by Microsoft and IBM. It stores raw PCM data, making it ideal for studio recording, mixing, and mastering. WAV files preserve 100% of the original sound but require large storage space.
🔹 What is FLAC?
FLAC (Free Lossless Audio Codec) is a compressed but lossless format. It reduces file size by up to 60% without losing any audio quality. FLAC supports full metadata, album art, and is perfect for music blogs, streaming, and archiving.
