The core of the process involves a crucial technical transformation: . An audio CD does not contain compressed files like FLAC or MP3. Instead, it stores raw, uncompressed Pulse-Code Modulation (PCM) audio, typically at a resolution of 16-bit, 44.1 kHz. Burning FLAC to an audio CD is therefore a two-stage operation. First, the FLAC file must be decoded back into a linear PCM stream. Second, this stream must be written to the CD in the Red Book audio standard format. In practice, when using XLD, the user simply selects the FLAC files (or a CUE sheet containing track breaks) and chooses “Burn Audio CD” from the File menu. Behind the interface, XLD is decompressing the FLAC on-the-fly, converting the data to 44.1 kHz/16-bit PCM (resampling if necessary), and passing this stream to macOS’s disc burning engine with instructions to author a Red Book-compliant disc. This seamless integration hides the complexity, but understanding it is key to troubleshooting.
This is the standard method, but you must convert your FLAC files to a format the Music app can read, such as (Apple Lossless) or How to burn flac files to regular music CD? burn flac to audio cd mac
The first and most significant hurdle for a Mac user is understanding that macOS’s built-in burning utility, Finder, does not support FLAC files for audio CD creation. While Finder can burn data discs (where FLAC files would remain as computer files) or audio CDs from uncompressed formats like AIFF or WAV, it will reject FLAC files for audio burning. Consequently, the user must abandon native tools and turn to third-party software. The most prominent and reliable solution for macOS is . XLD is a free, open-source, and highly respected utility specifically designed for transcoding between lossless audio formats. For a one-step, graphical alternative, Burn (freeware) or commercial applications like Toast Titanium are also viable. However, the gold standard for precision is XLD, as it provides granular control over the decoding process and integrates seamlessly with macOS’s disc burning frameworks. The core of the process involves a crucial
Click Burn. The software will create a temporary AIFF/WAV file on your hard drive. Do not move or delete the original FLACs during this process. Do not use your Mac for heavy tasks (video editing, gaming) while burning—buffer underruns cause skips. Burning FLAC to an audio CD is therefore
