如何刪除音樂庫中不必要的 mp3 標籤？

Question

要查看圖書館的污染情況，請嘗試：

find ./ -type f -iname "*.mp3" -exec /usr/bin/mid3v2 -l '{}' + | egrep -e "AENC|ASPI|COMM|COMR|ENCR|EQU2|ETCO|GEOB|GRID|LINK|MCDI|MLLT|OWNE|PRIV|PCNT|POPM|POSS|RBUF|RVA2|RVRB|SEEK|SIGN|SYLT|SYTC|TBPM|TCOM|TCOP|TDEN|TDLY|TDOR|TDRL|TDTG|TENC|TEXT|TFLT|TIPL|TIT3|TKEY|TLAN|TLEN|TMCL|TMED|TMOO|TOAL|TOFN|TOLY|TOPE|TOWN|TPE3|TPE4|TPOS|TPRO|TPUB|TRSN|TRSO|TSOA|TSOP|TSOT|TSRC|TSSE|TSST|TXXX|UFID|USER|USLT|WCOM|WCOP|WOAF|WOAR|WOAS|WORS|WPAY|WPUB|WXXX"

通常您可以用來mid3v2編輯 mp3 檔案的 ID3v2 標籤。

find ./ -type f -iname "*.mp3" -exec /usr/bin/mid3v2 --delete-frames=AENC,ASPI,COMM,COMR,ENCR,EQU2,ETCO,GEOB,GRID,LINK,MCDI,MLLT,OWNE,PRIV,PCNT,POPM,POSS,RBUF,RVA2,RVRB,SEEK,SIGN,SYLT,SYTC,TBPM,TCOM,TCOP,TDEN,TDLY,TDOR,TDRL,TDTG,TENC,TEXT,TFLT,TIPL,TIT3,TKEY,TLAN,TLEN,TMCL,TMED,TMOO,TOAL,TOFN,TOLY,TOPE,TOWN,TPE3,TPE4,TPOS,TPRO,TPUB,TRSN,TRSO,TSOA,TSOP,TSOT,TSRC,TSSE,TSST,TXXX,UFID,USER,USLT,WCOM,WCOP,WOAF,WOAR,WOAS,WORS,WPAY,WPUB,WXXX '{}' +

這將從當前目錄遞歸地找到所有 *.mp3 檔案並刪除幾乎所有的 id3v2 幀。它做到了極為快速地。幾乎全部意味著全部，但：

APIC  A picture for the track, usually the albumcover.
TIT1  Content group description (I guess could be deleted too)
TIT2  The song title
TPE1  The album artist
TPE2  The artists (includes featurings)
TRCK  Tracknumber
TALB  Albumtitle
TCON  Genre
TDRC  Year of release

比較id3v2.4規範

mid3v2 在刪除之前會隱式地將 TYER（發布年份的舊框架）轉換為 TDRC。實際上它會將每個操作的每個檔案轉換為id3v2.4。看man mid3v2。

再次測試它是否有效：

find ./ -type f -iname "*.mp3" -exec /usr/bin/mid3v2 -l '{}' + | egrep -e "AENC|ASPI|COMM|COMR|ENCR|EQU2|ETCO|GEOB|GRID|LINK|MCDI|MLLT|OWNE|PRIV|PCNT|POPM|POSS|RBUF|RVA2|RVRB|SEEK|SIGN|SYLT|SYTC|TBPM|TCOM|TCOP|TDEN|TDLY|TDOR|TDRL|TDTG|TENC|TEXT|TFLT|TIPL|TIT3|TKEY|TLAN|TLEN|TMCL|TMED|TMOO|TOAL|TOFN|TOLY|TOPE|TOWN|TPE3|TPE4|TPOS|TPRO|TPUB|TRSN|TRSO|TSOA|TSOP|TSOT|TSRC|TSSE|TSST|TXXX|UFID|USER|USLT|WCOM|WCOP|WOAF|WOAR|WOAS|WORS|WPAY|WPUB|WXXX"
