I can't imagine that reducing an audio stream by 300MB goes without losing information, even though FLAC is a lossless codec, but the hashes are identical: ffmpeg -v error -i org.mka -map 0 -f hash. Org.mka (450MB 15min 24bit MLP FBA 16-ch, Dolby TrueHD with Dolby Atmos)įlac_24bit.mka (270MB 15min 24bit FLAC in s32 sample format)įlac_16bit.mka (148MB 15min 16bit FLAC in s16 sample format). Interesting enough comparing the results using the ffmpeg hash filter I see no difference: I noticed that when encoding a 24bit TrueHD and/or DTS-HD MA audio stream to 24bit FLAC I get only a little compression gain, but compression it to 16bit FLAC gets huge space savings. flac Name Matroska Audio File Free Lossless Audio Codec File Extension. Right click on one or more Mka file (s) on your desktop and select Convert with Filestar. As lossy audio format I use Opus and on really highquality rips I tend to use FLAC. Convert Mka To Flac Download and install the latest version of Filestar. I'm currently encoding some movies from remuxes to AV1.
