    About FLV and FLAC

    FLV: FLV is the Flash Video format that powered early YouTube. Flash is gone, so FLV files usually need converting to play today.

    FLAC: FLAC is an open lossless format that shrinks audio to 50–60% of WAV size without losing any quality. It is the favourite format of audiophiles and hi-res music stores.
