In term of data retention, FLAC is like compressing a RAW image file by using a zip/rar, the data integrity is the same when you open the zip/rar and check the image. MP3 is like reducing the size of a RAW image by converting it to JPEG, data integrity is affected and the image won’t look as good anymore. The most common uncompressed audio format that people know is WAV files (but you can also find compressed WAV files).
