About the formats

What is WAV?

WAV (Waveform Audio File Format) was introduced by Microsoft and IBM in 1991 and is based on the RIFF container. It normally holds uncompressed PCM audio, so it keeps every detail of the recording, but a few minutes of CD-quality stereo already take tens of megabytes. Almost every audio editor, operating system and device can open it.

Use WAV for recording, editing, mastering and exchanging audio between studio tools, where quality must stay untouched. When you need to share or store large amounts of audio, FLAC gives the same quality in smaller files, and MP3 or AAC are best for casual listening.

What is FLAC?

FLAC (Free Lossless Audio Codec) is an open, royalty-free audio format maintained by the Xiph.Org Foundation. It compresses audio losslessly: the decoded sound is bit-for-bit identical to the original, yet files are noticeably smaller than WAV. It supports high resolutions, multichannel audio and metadata tags such as artist and cover art.

Use FLAC to archive CDs, store a music library in full quality or download high-resolution releases. It is ideal when you want smaller files than WAV without any loss. For phones with limited storage or players without FLAC support, a copy in AAC or MP3 is more practical.
