NAME

       mp3fs - mounts and transcodes FLACs to MP3s on the fly

SYNOPSIS

       mp3fs [OPTION]... FLACDIR MP3DIR

DESCRIPTION

       The mp3fs(1) command will mount the directory FLACDIR on MP3DIR. Thereafter, accessing MP3DIR will show
       the contents of FLACDIR, with all FLAC files transparently renamed and transcoded to MP3 format upon
       access.

OPTIONS

       -b, -obitrate=RATE
           Set the bitrate to use for encoding. Acceptable values for RATE are any which are allowed by the MP3
           format. According to the manual for LAME, this means:

           For sampling frequencies of 32, 44.1, and 48 kHz, RATE can be among 32, 40, 48, 56, 64, 80, 96, 112,
           128, 160, 192, 224, 256, and 320.

           For sampling frequencies of 16, 22.05, and 24 kHz, RATE can be among 8, 16, 24, 32, 40, 48, 56, 64,
           80, 96, 112, 128, 144, and 160.

           When in doubt, it is recommended to choose a bitrate among 96, 112, 128, 160, 192, 224, 256, and 320.
           If not specified, RATE defaults to 128.

       -d, -odebug
           Enable debug output. This will result in a large quantity of diagnostic information being printed to
           stderr as the program runs. This option will normally not be used. It implies -f.

       --gainmode, -ogainmode=MODE
           Set mode to use for interpreting ReplayGain tags. The allowed values for MODE are:

           0 - Ignore all ReplayGain tags.

           1 - Prefer album gain tag, but fall back to track gain if album gain is not present.

           2 - Use track gain if present.

       --gainref, -ogainref=REF
           Set the reference loudness in decibels to adjust ReplayGain tags. ReplayGain software usually
           defaults to a loudness of 89 dB, but if this is too quiet, a higher value can be set here, causing
           adjustment of ReplayGain values in tags.

       -f
           Run in foreground instead of detaching from the terminal.

       -h, --help
           Print usage information.

       --quality, -oquality=QUALITY
           Set quality for encoding, as understood by LAME. The slowest and best quality is 0, while 9 is the
           fastest and worst quality. The default value is 5, although according to the LAME manual, 2 is
           recommended.

       -s
           Force single-threaded operation.

       -V, --version
           Output version information.
