Ripping CDs to FLAC gives you the best of both worlds: physical ownership of the disc plus lossless digital copies you can play from any device. FLAC (Free Lossless Audio Codec) preserves 100% of the CD's audio data while compressing file sizes by 40–60%.
A single ripped CD takes about 300–400 MB in FLAC format. Even a modest 500-CD collection fits comfortably on a 256 GB drive. This guide walks you through the setup, ripping process, and metadata tagging to build a perfect digital library.
Get a CD Drive and Software
If your computer doesn't have a built-in CD drive, buy a USB external drive ($15–$25). Any brand works for ripping — you don't need an expensive audiophile drive.
Software: On Windows, use Exact Audio Copy (EAC) — it's free and produces verified bit-perfect rips. On Mac, use XLD (X Lossless Decoder) — also free and equally accurate. Both tools compare your rip against the AccurateRip database to verify the copy is bit-perfect.
Configure Your Ripping Software
In EAC: Run the configuration wizard on first launch. Set output format to FLAC. Enable AccurateRip verification. Set error correction to 'Secure' mode. Choose an output folder structure (we recommend: Artist/Album/Track Number - Track Title.flac).
In XLD: Open Preferences → General. Set output format to FLAC. Enable AccurateRip. Set read mode to 'Paranoid' for maximum accuracy. Configure output filename template to match your preferred folder structure.
Rip Your CDs
Insert a CD. The software should automatically detect it and fetch track names from online databases (CDDB/MusicBrainz). Verify the metadata is correct — sometimes it pulls wrong info for compilations or rare releases.
Click 'Rip' or 'Extract' and wait. A typical CD takes 5–15 minutes depending on your drive speed and error correction settings. You'll get a folder with individual FLAC files for each track. Check the rip log — green/accurate results mean a perfect copy.
Tag Metadata with MusicBrainz Picard
Even if your ripping software got the basic tags right, MusicBrainz Picard (free, cross-platform) adds comprehensive metadata: correct album art, full credits, release year, genre, and standardized formatting. It uses acoustic fingerprinting to match files to the correct release.
Open Picard, drag your ripped folders in, let it match each album, review the results, and save. This ensures your digital library has consistent, accurate metadata that music players and servers display correctly.
Organize and Back Up
Store your FLAC library in a consistent folder structure: Music/Artist Name/Album Name (Year)/01 - Track Title.flac. This works universally with all music players and servers.
Back up your library to at least one additional location: an external hard drive, NAS, or cloud storage. Your CDs serve as the physical archive, but re-ripping hundreds of CDs is tedious. A backup drive costs $50–$80 and saves hours of potential re-work.
Pro Tips
- Rip in 'Secure' or 'Paranoid' mode — it's slower but guarantees accuracy
- Always verify against AccurateRip — this confirms your rip matches other verified copies
- FLAC compression level doesn't affect audio quality — only file size and decode speed
- Keep rip logs — they prove the accuracy of your copies if you ever need to verify
- Rip CDs before shelving them — build your digital library from day one
- Consider running a personal music server (Navidrome, Jellyfin) for streaming your FLAC library from any device
Frequently Asked Questions
Is FLAC really lossless?
Yes. FLAC is mathematically lossless — the decoded audio is bit-for-bit identical to the original CD data. It compresses file sizes by 40–60% using techniques similar to ZIP, but unlike MP3, no audio data is discarded. FLAC decoded = original CD audio.
Why FLAC instead of MP3?
MP3 is lossy — it permanently removes audio data to shrink files. A 320kbps MP3 is good but not identical to the CD. FLAC preserves everything. Storage is cheap enough now that there's no reason to use lossy formats for a permanent library.
Can I play FLAC on my phone?
Yes. Android supports FLAC natively. On iPhone, apps like VLC, Foobar2000, and Plexamp play FLAC files. If you run a personal music server (Navidrome, Jellyfin, Plex), mobile apps stream your FLAC library from anywhere.
