Notes

• Default FLAC compression is -8 -p -r 15 -l 32 --lax --no-padding --no-seektable.
• DSF is converted at 32bit/192kHz, for a coherent final file size.
• Converted tags are according with musicbrainz (as far as possible) (https://picard-docs.musicbrainz.org/en/appendices/tag_mapping.html).
• --cd && --48khz options are destructive.
• --fast use compression level --compression-level-0.
• ReplayGain use rsgain by default (https://github.com/complexlogic/rsgain), if not installed use metaflac.
• --tmp increase speed of decoding if you use tmpfs for /tmp directory, but keep in mind the size of this fs.
