Luna CD Ripper

You probably do not need another folder full of files called Track 01, Track 02 and Track 03.
You definitely do not need a hundred CDs scattered around the house because ripping them properly was too much hassle.

Luna CD Ripper is a free Windows CD ripping and archival program built with accessibility first.
Insert a disc, let Luna identify it, check the metadata, choose where you want it to go and rip it into a properly named, properly tagged and properly verified digital archive.

Luna is designed for screen reader users from the beginning rather than having accessibility bolted on somewhere near the end.
Progress, verification information, metadata activity and warnings are presented as useful text, and the entire workflow is intended to make sense from the keyboard.

Rip a CD without turning it into a research project.

The ordinary workflow is deliberately straightforward:

• Insert an audio CD.
• Let Luna detect it automatically, or press Refresh.
• Look up album and track metadata.
• Review and correct anything which is wrong.
• Choose your output format and destination.
• Review the album one final time.
• Rip.

The complicated bits happen underneath.
You should not need to understand CD frame offsets, C2 pointers or checksum databases before you can rescue an album from a shelf.

Secure ripping, because CDs are not hard drives.

Optical discs can be scratched, dirty, badly pressed or simply read differently by different drives.
Luna's secure ripping mode is designed to do more than read a track once and hope for the best.

Depending on the disc and drive, Luna can use:

• Repeated reads of the audio.
• CRC comparison between passes.
• C2 error information where the drive genuinely supports it.
• Targeted rescue reads for unstable regions.
• Slower recovery passes when a section needs more attention.
• Independent AccurateRip verification.

If a track needs more work, Luna tells you.
If a track verifies cleanly, Luna tells you that too.
The aim is not merely to create files, but to give you useful evidence about whether those files are trustworthy.

AccurateRip verification.

Luna integrates with AccurateRip, a database of checksums from known CD rips.

When your rip matches other known copies of the same pressing, Luna can use that as strong independent evidence that the audio was read correctly.

An AccurateRip miss is not automatically a failed rip.
Uncommon pressings and obscure discs may simply not exist in the database yet, so Luna also reports its own local secure-verification evidence separately.

Drive sample offsets can be detected automatically where possible or entered manually if you already know the correct value for your drive.

Metadata that does not just sit there looking frozen.

Luna can combine several metadata sources:

• MusicBrainz.
• GnuDB/CDDB.
• CD-TEXT from the disc itself where available.
• Luna's local metadata cache.

If several releases match the same disc, Luna lets you choose the correct edition rather than silently picking one and hoping nobody notices.

Cover artwork in the background.

Once Luna knows the release, cover artwork can download separately without holding up the main metadata result.

A persistent artwork status tells you whether the cover is:

• Not requested.
• Loaded from the local cache.
• Downloading in the background.
• Downloaded successfully.
• Unavailable or failed.

So yes, when Luna says the artwork is continuing in the background, it actually is.

Review before you rip.

A technically perfect rip with bad tags is still annoying.

Before ripping begins, Luna gives you a final review of:

• Album title and artist.
• Year and genre.
• Disc number and total discs.
• Output format.
• Destination folder.
• Naming format.
• The complete track list.

If something is wrong, go back and fix it.
If everything looks right, start the rip.

FLAC, WAV, Ogg and MP3.

Luna can create:

• FLAC.
• WAV.
• Ogg Vorbis.
• MP3 at 128 kbps.
• MP3 at 320 kbps.

For a long-term archive, FLAC is the sensible default: lossless audio, useful tagging and considerably less wasted space than WAV.

Luna also lets you control how folders and file names are built using substitutions for album artist, track artist, album, year, genre, disc number, track number and track title.

Know what the drive is actually doing.

During a rip, Luna reports actual decoded CD throughput rather than just displaying the maximum speed printed on the drive.

You may see something such as:

Reading at 12.7x CD speed; average 12.4x. Track 68% complete.

The current requested drive speed is shown separately from the measured throughput.
This is useful because optical drives sometimes have opinions of their own.

Results you can actually inspect.

When the disc is finished, Luna presents one row per track with verification information including:

• Archive status.
• AccurateRip result.
• Local secure verification.
• C2 information.
• Rescue evidence.
• Pre-emphasis status.
• Output-integrity checks.

The results screen is not just a green tick and a cheerful noise.
It is there to tell you what Luna proved, what it could not prove and where you may want to investigate further.

Built for archiving, not just converting.

Luna can create preservation information alongside the ripped album, including:

• Detailed rip logs.
• Archive manifests with hashes.
• CUE sheets.
• Disc Archaeology reports.
• ReplayGain metadata.
• Pre-emphasis information and optional playback derivatives.
• Hidden Track One Audio where the disc and drive expose it reliably.

Disc Archaeology is deliberately textual and screen reader friendly.
It can record less ordinary disc features such as pregaps, mixed-mode/data sessions, ISRCs, UPC/MCN information, indexes, pre-emphasis and possible hidden audio before track 1.

Check your archive again later.

A successful rip today does not magically protect a storage drive forever.

Luna's archive manifests can be used later to revalidate your archived library.
Luna can scan for its manifests and check that the files which exist now still match the hashes recorded when they were archived.

That is useful after moving a large music collection, restoring from backup or several years down the road when you would like something more convincing than "well, the files are still in the folder."

Batch archive mode.

Got a pile of discs rather than one?

Batch archive mode can eject a successfully completed CD and prompt you for the next one, while keeping a session summary of what has been processed.

Luna does not blindly begin ripping the next disc as soon as you insert it.
You still get the metadata and review stages first, because album number 47 deserves correct tags just as much as album number 1 did before you got tired.

A note about copyright.

Luna gives you the technical ability to copy audio from a CD.
That does not automatically give you the legal right to redistribute whatever is on it.

Copyright, private copying and format-shifting rules vary by country and by material.
You are responsible for making sure that your use of Luna and the resulting files is lawful where you live.

Do not redistribute, upload, sell or publish copyrighted music unless you have the rights or permission required to do so.
