lo48576@hard-wi.red YOSHIOKA Takuma Moonbase59/loudgain loudgain is a versatile ReplayGain 2.0 loudness normalizer, based on the EBU R128/ITU BS.1770 standard (-18 LUFS) and supports FLAC/Ogg/MP2/MP3/MP4/M4A/ALAC/Opus/ASF/WMA/WAV/WavPack/AIFF/APE audio files. It uses the well-known mp3gain commandline syntax but will never modify the actual audio data.
