Quick Guide: Preparing MP3, WAV, OGG, WMA & AC3 for CD Burn

Burn MP3/WAV/OGG/WMA/AC3 to CD: Step-by-Step Guide

What this does

Create an audio CD playable in standard CD players by converting common audio files (MP3, WAV, OGG, WMA, AC3) into the CD Audio format (16-bit PCM, 44.1 kHz) and burning them to a blank CD-R.

What you’ll need

• Computer with a CD/DVD burner and a blank CD-R (audio CDs hold ~74–80 minutes).
• Sufficient disk space for temporary converted files (1 minute ≈ 10 MB when uncompressed).
• Burning software that supports creating audio CDs from mixed input formats (examples: Exact Audio Copy, ImgBurn + converter, iTunes, CDBurnerXP, or commercial apps).
• Optional: decoder libraries/codecs (e.g., FFmpeg) if your burner doesn’t natively support some formats (OGG, AC3).

Step-by-step

1. Collect your source files

• Put all MP3, WAV, OGG, WMA, AC3 files into a single folder.
• Check total playback time; ensure it’s ≤ 74–80 minutes for one CD.

2. Convert non-WAV files to CD audio format (if software requires WAV/PCM)

• If the burning app accepts compressed formats directly, you can skip explicit conversion.
• Otherwise, batch-convert files to 16-bit 44.1 kHz WAV (PCM). Using FFmpeg (example command for one file):

  Code
  Copy CodeCopied
  ffmpeg -i input.ext -ar 44100 -ac 2 -sample_fmt s16 output.wav 

  • Replace input.ext with MP3/OGG/WMA/AC3 filename. Repeat for each file or script batch processing.

3. Normalize or adjust levels (optional)

• Use a tool (e.g., Audacity, foobar2000) to apply consistent loudness so tracks play at similar volume.

4. Assemble the track order

• Rename files with numeric prefixes (01 Title.wav, 02 Title.wav) or use your burning software’s track order feature.

5. Create the audio CD project in your burning software

• Open your chosen burning app and select “Audio CD” or equivalent.
• Add tracks in desired order. Confirm each track’s length and total runtime.

6. Configure burning settings

• Select burn speed: choose a lower speed (e.g., 4x–16x) for higher compatibility and fewer errors.
• Enable finalization (close disc) so it’s playable on other CD players.
• Do NOT select data-disc options—must be Audio CD (Red Book).

7. Burn the disc

• Insert a blank CD-R.
• Start burn and wait until completion. Do not interrupt the burn or eject until finished.

8. Verify the burn (recommended)

• Use the software’s verification option or play the finished disc in a CD player/computer to confirm all tracks play correctly.

Troubleshooting

• Short tracks cut off or gaps wrong: ensure burning mode is “Audio CD” (not MP3/data) and check gap settings.
• Unsupported source format: convert to WAV/PCM via FFmpeg before burning.
• Disc not recognized by player: try burning at lower speed, use a different brand of CD-R, or finalize the disc.

Quick tips

• Use CD-R, not CD-RW, for maximum compatibility.
• For multiple CDs or longer audio, split tracks across discs by total runtime.
• Keep a backup of converted WAVs until you confirm the burn is successful.
