Worth knowing about the flac format FLAC is the abbreviation of "Free Lossless Audio Codec" and unlike the mp3 format it means lossless data compression, which can be superior to the CD even in the case of a 24-bit resolution, but requires only about half of the data volume of a wav file. So FLAC […]

WAV

WAV files are used to store audio signals – such as music or voice recordings. WAV files are uncompressed, so they offer a perfect quality at the cost of a really huge file size. They usually contain PCM-signals based on Microsoft’s Resource Interchange File Format (RIFF). Before the advent of mp3, WAV was often used […]
