FLAC and Total Recorder
FLAC is a lossless audio codec. Lossless means that if you encode uncompressed (PCM) data into FLAC format and then decode the resulting FLAC file, the decoded file will be exactly the same as the original PCM file.
Support for FLAC format is built into Total Recorder. You do not need to download any additional software or libraries to work with FLAC format.
Total Recorder Version 5.3 and later support FLAC format based on version 1.1.2 of the FLAC libraries. Note that Total Recorder supports FLAC files only in "native" FLAC format; Ogg-FLAC files are not supported.
