Bigasoft FLAC Converter is more than its name suggests. Besides helping you convert FLAC and other audio formats, this utility also enables you to easily extract sound content from your favorite movies.
The program is compatible with various media formats, supports batch conversion, and features easy-to-configure output settings. In addition, you can choose individual output profiles when batch converting files and trim the imported files if necessary.
A feature that's currently missing from this program and, at some point, might come in handy to some people is the ability to split the input video or audio into multiple segments before launching the conversion process. Another thing that bothered me while testing the tool was that it took a while to launch and to import the files I needed to convert. Still, this doesn't mean that it will happen the same on your computer. You can test the trial version of the tool without paying a buck and see how it works on your Mac.
Briefly, Bigasoft FLAC Converter provides you with quality results, is very simple to handle, and comes with a reasonable price. I'd say it's worth giving it a try if the aforementioned aspects mean nothing to you.
