Practical guides

Most audio problems are caused not by poor equipment but by everyday mistakes: a file has been re-encoded several times, tags are filled in haphazardly, there is no backup. This section collects short guides to working with your own audio files. They are written in general terms: every program names its menu items differently, so check its help pages. This is also where the catalogue of standalone articles will live.

One evening spent tidying your music library saves years of hunting for "that one file".

— Editor's note

How this section works: we describe the steps in general terms, without tying them to specific programs or brands and without advertising. The guides apply only to your own lawfully obtained files and CDs. We do not explain how to download music from pirate sites or bypass copy protection.

Guides

Five tasks that almost everyone with their own music collection runs into.

Choose an archive format

For the master copy of your collection, choose a lossless format such as FLAC or ALAC: from it you can later make a file in any format without losses piling up. For devices with little storage, make separate compressed copies.

Comparisons

Convert your files without needless loss

Convert from a lossless source, not from an already compressed file. Re-encoding with a lossy codec degrades quality, and converting MP3 to FLAC does not bring back the discarded information — the file just gets bigger.

Tools

Tidy up your metadata

Fill in tags consistently: artist, album, year, track number, genre. Embed cover art in the file at a moderate size. Before a bulk edit, copy the folder — it is easier to roll back a mistake in a hundred files than to fix it.

Tools

Back up your music library

Keep a copy of your collection on a separate drive or in cloud storage — ideally both. Check from time to time that the copy opens, and update it after major changes.

Fixes

Check a file before opening it

Look at the file's full extension and size. An audio file should not be a program, a password-protected archive or a shortcut. If a file comes from an unknown source, scan it with antivirus software before opening it.

Article catalogue for English-language readers

This section will feature standalone articles written for English-language readers. They are written with their needs in mind and are not translations of material from other language versions of the site.

Topics the editors are planning

  • Does lossless audio make sense over Bluetooth headphones?
  • How to move a music library to a new computer without losing tags
  • Using Creative Commons and public domain music in your own videos
  • How to digitise vinyl records and cassettes at home

Editorial rules

  • Articles in this catalogue are written separately for each language version and are not translations.
  • Some articles link to third-party websites, including gaming services; we do not control their content, prices or terms.
  • We do not publish music download links, service rankings, prices or reviews.

How to rip your CD collection

  1. Prepare the discs

    Wipe the discs with a soft cloth from the centre outwards. Scratches and dirt cause read errors, which you later hear as clicks and dropouts.

  2. Choose a program and a format

    Use a CD ripping program that can verify read accuracy. For an archive, choose a lossless format: it preserves the sound of the disc in full.

    An Audio CD is recorded at 44.1 kHz, 16-bit, in stereo. A lossless file keeps exactly these parameters.

  3. Set up the metadata

    Before ripping, check that the program has identified the album and tracks correctly. Fix titles and numbers if the data came through with errors.

  4. Rip and verify

    Start ripping and check the log: if the program reports read errors on a track, clean the disc and try again.

  5. Make compressed copies for your devices

    From the lossless archive files, create separate compressed copies for your phone or player. The archive itself stays untouched.

  6. Keep a backup

    Copy the resulting archive to a second drive. Keep the discs too: they remain proof that the copy was made from your own copy of the album.

  • Tools

    Types of audio software: player, converter, tag editor, CD ripper, audio editor, library manager — no brands.

  • Comparisons

    MP3, AAC, Opus, FLAC, ALAC and WAV compared, plus legal ways to listen to music: pros and cons.

  • Fixes

    A file won't play, the sound distorts, tags are mixed up, an "mp3" turned out to be a program, the library vanished — what to do.
