mp3fs

MP3FS(1)							   User Commands							  MP3FS(1)

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.
