Replaygain 2.0 loudness normalizer

Usage

rsgain [OPTIONS] <command> ...

Overview

rsgain (really simple gain) is a ReplayGain 2.0 command-line utility.

It applies loudness metadata tags to audio and video files while leaving the audio stream untouched.

A ReplayGain-compatible player will dynamically adjust the volume of your tagged files during playback.

rsgain supports writing tags to the following file types:

- AIFF (.aiff, .aif, .snd)
- APE (.ape)
- FLAC (.flac)
- MP2 (.mp2)
- MP3 (.mp3)
- MP4 (.m4a)
- Musepack (.mpc)
- Ogg (.ogg, .oga, .spx)
- Opus (.opus)
- TAK (.tak)
- WAV (.wav)
- WavPack (.wv)
- WMA (.wma).

Options and commands

-h, --help: Show help.

-v, --version: Show version number.

`easy`	Easy Mode: Recursively scan a directory with recommended settings.
`custom`	Custom Mode: Scan individual files with custom settings.

Run rsgain easy --help or rsgain custom --help for more information.

Easy mode

Usage: rsgain easy [OPTIONS] DIRECTORY

Easy Mode recursively scans a directory using the recommended settings for each file type.

Easy Mode assumes that you have your music library organized with each album in its own folder.

Options

`-h, --help`	Show help.
`-q, --quiet`	Don't print scanning status messages.
`-S, --skip-existing`	Don't scan files with existing ReplayGain information.
`-m n, --multithread=n`	Scan files with `n` parallel threads.
`-p s, --preset=s`	Load scan preset `s`.
`-O, --output`	Output tab-delimited scan data to CSV file per directory.
`-O s, --output=s`	Output with sep header (needed for Microsoft Excel compatibility).
`-O a, --output=a`	Output with files sorted in alphanumeric order.

Custom mode

Usage: rsgain custom [OPTIONS] FILES...

Custom Mode allows the user to specify the options to scan files with.

The list of files to scan must be listed explicitly after the options.

Options

-h, --help: Show help.

-a, --album: Calculate album gain and peak.

-S, --skip-existing: Don't scan files with existing ReplayGain information.

-s s, --tagmode=s: Scan files but don't write ReplayGain tags (default).

-s d, --tagmode=d: Delete ReplayGain tags from files.

-s i, --tagmode=i: Scan and write ReplayGain 2.0 tags to files.

-l n, --loudness=n: Use n LUFS as target loudness (-30 ≤ n ≤ -5).

-c n, --clip-mode=n: No clipping protection (default).

-c p, --clip-mode=p: Clipping protection enabled for positive-gain values only.

-c a, --clip-mode=a: Clipping protection always enabled.

-m n, --max-peak=n: Use max peak level n dB for clipping protection.

-t, --true-peak: Use true peak for peak calculations.

-L, --lowercase: Write lowercase tags (MP2/MP3/MP4/WMA/WAV/AIFF).
This is non-standard but sometimes needed.

-I keep, --id3v2-version=keep: Keep file's existing ID3v2 version, 3 if none exists (default).

-I 3, --id3v2-version=3: Write ID3v2.3 tags to MP2/MP3/WAV/AIFF.

-I 4, --id3v2-version=4: Write ID3v2.4 tags to MP2/MP3/WAV/AIFF.

-o d, --opus-mode=d: Write standard ReplayGain tags, clear header output gain (default).

-o r, --opus-mode=r: Write R128_*_GAIN tags, clear header output gain.

-o s, --opus-mode=s: Same as 'r', plus override target loudness to -23 LUFS.

-o t, --opus-mode=t: Write track gain to header output gain.

-o a, --opus-mode=a: Write album gain to header output gain.

-O, --output: Output tab-delimited scan data to stdout.

-O s, --output=s: Output with sep header (needed for Microsoft Excel compatibility).

-O a, --output=a: Output with files sorted in alphanumeric order.

-p, --preserve-mtimes: Preserve file mtimes.

-q, --quiet: Don't print scanning status messages.
