Q:"I have been searching for a decent free or paid FLAC splitter to split up my large FLAC files but have not had any luck so far. Most seem to be either for Windows or be costly. Does anyone know of any good ones?" - From Reddit
Differing from lossy compression coding like MP3, AAC, OGG, etc., FLAC (Free Lossless Audio Codec) developed by Xiph.Org Foundation is a lossless compression coding, which means that all audio compressed with FLAC encoding will lose no information. Due to this lossless property, FLAC coding format has been applied in many software and hardware audio products, like CDs. But generally, file with the extension .flac is large whether it's ripped from CDs or downloaded on Internet. This why you have to split FLAC files into several short tracks. Here I'll show how to make it without/with cue.
Part 1. How to Split FLAC File without Cue
Joyoshare Audio Cutter
Joyoshare Audio Cutter is really a thorough FLAC splitter that you shouldn't miss to split and cut your FLAC audio files. It provides millisecond precision timing to ensure the accuracy of cutting and splitting. Plus, it features a high-speed mode that can promise the whole splitting process to be done with lossless quality and frame.
Other than the ability of 60X-speed and lossless cut or split, it is built with a media editor, allowing you to custom the FLAC files, like apply sound effects, control its volume, trim FLAC, adjust parameters, etc. The file formats it supports is of course more than FLAC. Many other formats like MP3, OGG, AAC, AC3, CAF, WAV, WMA, M4A, MP4, FLV, MPG, MTS, MOV, MKV, etc. get the same support.
Step 1: Add FLAC file to Joyoshare Audio Cutter
Based on your system, select the proper version of Joyoshare Audio Cutter to download and install. Then, open the program and go to "Open" to access your local folder and choose the FLAC file to it. Or, you can drag and drop the FLAC audio file to the specified position to start.
Step 2: Specify splitting mode
Next, click "Format" to opt for the cutting mode from the given two modes. With the high-speed mode, splitting FLAC files can be done with breathtaking speed and there is no deterioration of quality accompanied. The encoding mode entitles you to edit FLAC file and set up file format like adjusting codec, sample rate, bit rate, channel, in a customized way. Choose either of them as you demand. Don't forget to confirm an output format in the designated mode.
Step 3: Pinpoint cutting sections
Now, get yourself back to the main interface and preview the FLAC audio file to determine what you need to cut or where you want to split. After that, click to stop playing and start cutting off unwanted tracks by dragging the yellow timeline, setting segment start time and end time, or manually entering temporal interval. To produce more FLAC tracks, touch "+ Add Segment" option and keep what you need as described above.
Step 4: Edit FLAC files (optional)
The one who splits FLAC files with the encoding mode is allowed to edit FLAC audio after cutting and splitting. For this, tap "Edit" icon to go for the editing window and select to trim files, apply sound effects, adjust volume, etc. Afterward, return to the previous window.
Step 5: Save split FLAC file(s)
If there is a need for you to merge these split FLAC tracks into one, tick "Merge Segments". Next, simply click on "Start" button to export them and press "Open The Output Folder" to have a local check.
Audacity is an open-source multiple audio editor, recorder and mixer freeware applicable to Windows, Mac, and Linux.
