Burning FLAC Files Directly to CD Audio?
ImgBurn is a free CD burning software and it supports the FLAC audio format amongst others (AAC, APE, M4A, MP3, MP4, MPC, OGG, PCM, WAV, WMA and WV).
ImgBurn is often recommended on SuperUser and on other sites (LifeHacker for instance) for all its features.
Install the free version of Nero 9. Open Nero and create a New Audio CD. Drag the .flac files directly into Nero the same way you would with .wav or .mp3 files. If Nero doesn’t report any errors, you should be able to click Burn and create the CD.
If Nero does report an error, you need to download and install the Nero Mega Plugin Pack (which is free). After it’s installed, try dragging the flac files directly into Nero again and this time you shouldn’t get any errors.

Burrrn is a little tool for creating audio CDs with CD-Text from various audio files. Supported formats are: wav, mp3, mpc, ogg, aac, mp4, ape, flac, ofr, wv, tta, m3u, pls and fpl playlists and cue sheets. You can also burn EAC’s noncompliant image + cue sheets! Burrrn can read all types of tags from all these formats (including ape tags in mp3). Burrrn uses cdrdao.exe for burning.
Burrrn is freeware.
