Frequently Asked Questions

How to open a FLAC file?

VLC, foobar2000, Winamp, and the Linux desktop decode FLAC out of the box. In the studio, Reaper and Ableton Live import FLAC while preserving metadata. If you need playback on constrained devices, transcode to ALAC or high‑bit‑rate MP3 with no audible penalty in casual listening.

What is a FLAC file?

Free Lossless Audio Codec (FLAC) compresses PCM audio by 30‑60 % without discarding information, making it ideal for archiving CDs and hi‑res mixes. It uses linear prediction and Rice coding and wraps metadata like cuesheets and artwork in a flexible block structure. Developer Josh Coalson released FLAC 1.0 under the open‑source BSD licence in 2001 as an answer to proprietary formats like Monkey’s Audio. Within a decade, hardware vendors Cowon, FiiO, Logitech Squeezebox added native decoding. In 2015, Apple began supporting FLAC in iOS 11’s Files app, cementing its place as the de‑facto lossless standard.
