FLAC vs AAC Format Comparison

Aspect	FLAC (Source Format)	AAC (Target Format)
Format Overview	FLAC Free Lossless Audio Codec FLAC is an open‑source, lossless audio compression format developed by the Xiph.Org Foundation. It preserves 100% of the original audio data while reducing file size. Lossless Compressed	AAC Advanced Audio Coding AAC is a lossy digital audio compression format providing better sound quality than MP3 at similar bit rates, widely used in streaming and mobile devices. Lossy Compressed
Technical Specifications	Sample Rates: 8kHz - 384kHz Bit Depths: 16, 24, 32-bit Encoding: Lossless PCM with predictive coding Compression Levels: 0 - 8 Channels: mono (1), stereo (2), multichannel (up to 8)	Sample Rates: 8kHz - 96kHz Bit Rate Modes: CBR, VBR Profiles: LC, HE, HEv2, LD, ELD Max Channels: Up to 48
Advantages	Perfect reconstruction of original audio (lossless) Significant file‑size reduction vs WAV/AIFF Fast decoding and reasonable encoding speed Embedded checksums for error detection Metadata tagging and cover art support	High quality at moderate bitrates Wide device and platform support Supports multiple profiles and VBR Low decoding complexity
Disadvantages	Larger than lossy formats (MP3, AAC) Less efficient for low bandwidth streaming Limited hardware support on older devices	Lossy—some audio data is discarded Commercial licensing may apply Less suitable for professional archiving
Compatibility	Excellent: VLC, Foobar2000, Most Linux distros Good: iTunes (with plugin), Windows Media Player (with plugin), Modern browsers via libraries Limited: Legacy portable players	Excellent: iOS, Spotify, YouTube, Modern Android Good: VLC, Windows Media Player, Browsers with HTML5 Limited: Older car stereos
Common Uses	Archival of master recordings High-resolution audio downloads Digital music libraries Audiophile listening setups	Music streaming (Apple Music, Spotify) Digital downloads Podcasts and audiobooks Audio tracks for video files
