How to Check FLAC Audio Files for Errors

There are many audio file formats some of them are more popular than the others. For example, we are all familiar with the MP3 audio file format which became popular in the late 1990s because of their high compression and negligible quality loss.

Compression was very important in old days when data storage devices were expensive but now-a-days both the local data storage and the cloud data storage has become cheaper than ever before. This is why now audio file formats like FLAC have become popular that do not provide much of a compression but do offer very high quality of the sound reproduction. Similarly, HEIC image file formats have gained popularity because of their high quality content despite the fact that they provide very low level of data compression.

FLAC is a very high quality audio file format and if you have a collection of FLAC audio file then it is a good idea to check them for possible corruption or other errors. This can be done easily using FLAC Frontend which comes with the FLAC command line program too. Here is how:
