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.

What is a MP4 file?

MP4 (MPEG‑4 Part 14) is the dominant container for online video. Based on QuickTime atoms, it can hold H.264/AVC, HEVC, AV1, AAC, AC‑3, timed text, and fragmented segments for adaptive streaming. Finalised in 2001 and revised in 2003 (ISO/IEC 14496‑14), MP4 became the hand‑off format of choice thanks to the iPod Video and PlayStation Portable. The arrival of HLS and DASH further entrenched MP4, which supports ‘moov’ boxes at either head or tail for progressive download or live streams.
