Preciso de uma ferramenta de linha de comando para converter vários XXX.flacarquivos XXX.aiffenquanto preserva as tags (artista, título, álbum, etc.). Nenhuma das ferramentas que experimentei (ffmpeg, sox, flac) parece funcionar bem. Aqui está um exemplo:
ygabuev@core:~/Music/2019 Sun Ra - Crystal Spears [FLAC]$ ffmpeg -loglevel info -i "01 - Crystal Spears.flac" -map_metadata 0 -id3v2_version 3 out.aiff

[swscaler @ 0x55bc89a85c40] deprecated pixel format used, make sure you did set range correctly
[aiff @ 0x55bc8999bc00] Frame rate very high for a muxer not efficiently supporting it.
Please consider specifying a lower framerate, a different muxer or -vsync 2

Pode-se observar que após a conversão a única tag restante é “título”.
Posso fazer o trabalho apenas com ffmpeg ou sox? Ou devo usar outras ferramentas de conversão/etiquetagem? O que você pode recomendar?
Minha configuração: Ubuntu 18.04.3, ffmpeg 3.4.6, sox v14.4.2.

Adicionar -write_id3v2 1opção de saída. Isso está desativado por padrão para o muxer AIFF. Ver ffmpeg -h muxer=aiff.
ffmpeg -i input.flac -write_id3v2 1 -c:v copy output.aiff
