{{DISPLAYTITLE:{{spmono|ym}}}}
A very personal Windows Batch script for the downloading of music or audio tracks from YouTube to a local place (here in this case is <code>D:\<wbr />_<wbr />W<wbr />M<wbr />D<wbr />\</code>) using a locally stored up-to-date Net<wbr />scape-styled {{spmono|coo<wbr />kies<wbr />.<wbr />txt}} (here in this case, it is located at <code>D:\<wbr />Omni<wbr />gena<wbr />\<wbr />coo<wbr />kies<wbr />.<wbr />txt</code>) that automatically produced by {{spmono|yt<wbr />-<wbr />dlp}}. It requires the following software to be properly set up in {{spmono|%PATH%}} (here in my case is <code>C:\<wbr />_<wbr />c<wbr />\</code>):
* [https://exiftool.org/#alone {{spmono|exiftool}}];
* [https://github.com/yt-dlp/FFmpeg-Builds/releases/latest/download/ffmpeg-master-latest-win64-gpl-shared.zip {{spmono|ffmpeg}}];
* [https://github.com/xiph/flac/releases/latest {{spmono|flac}}];
* [https://github.com/google/jpegli/actions/workflows/release.yaml?query=is%3Asuccess {{spmono|jpegli}}];
* [https://www.rarewares.org/rrw/neroaac.php Nero AAC Encoder] (with {{spmono|neroAacTag.exe}} renamed to {{spmono|aact.exe}});
* [https://github.com/nu774/qaac/releases/latest {{spmono|qaac}}];
* [https://drive.google.com/file/d/1Xp5TnAye_lqZv3W8Ye7iuQAB5JlHbdi2/ {{spmono|QTFiles}} for {{spmono|qaac}}]; and
* [https://github.com/yt-dlp/yt-dlp-nightly-builds/releases/latest/download/yt-dlp.exe {{spmono|yt-dlp}}].
By default, this batch script will download the audiotrack from the given URL ({{spmono|yt-dlp}}), convert it to an intermediate .{{spmono|flac}} file ({{spmono|ffmpeg}}), re-encode it as .{{spmono|m4a}} ({{spmono|qaac}}), and then crop the thumbnail image downloaded from the URL to 1:1 ({{spmono|ffmpeg}}) and add it as the .{{spmono|m4a}} file’s cover image (Nero AAC Encoder). The script also accepts three switches set out as follows:
* <code>'''-a'''</code>: changes to {{spmono|ya}} mode where the naming pattern is slightly different, the cover image is not cropped to 1:1, and the audio quality is slightly lower (<code>-v 0</code> → <code>-V 127</code>);
* <code>'''-s'''</code>: changes to {{spmono|yms}} mode where the exact frame at the 64th second of the video is extracted, proportionally scaled if needed by making its shorter edge at exactly 1,200 px, cropped to 1:1, and set as the cover image of the file;
** (specially, if <code>'''-ss''' <span style="color: #0663ba;">'''''n'''''</span></code> is used, then the given number <span style="color: #0663ba;">{{spmono|'''''n'''''}}</span> shall surpass the default value, 64, and be used for <code>-ss</code> in the final {{spmono|ffmpeg}} command;) and
* <code>'''-k'''</code>: keeps the intermediate .{{spmono|flac}} file for future uses. Although it is a .{{spmono|flac}} file, it does not have and cannot produce any acoustic improvements; therefore it is only recommended to keep it if it shall be further edited to ensure there is no quality loss in re-encoding.

These files shall be put into <code>%<wbr />App<wbr />Data<wbr />%<wbr />\<wbr />yt<wbr />-<wbr />dlp</code> with no extension attached to their filenames.
