"Sawing" FLAC

On a large, well-known tracker, people often began to share their copies of discs, in flac / ape / wavepack (wv) format, with a file-cue.

In fact, everything is smooth. Indeed, there are players that support the whole thing, and it really works. BUT.

My hobbies are related to electronic club music, respectively, for the sake of one or two tracks, I didn’t want to cut the whole discs before the party (it’s better to make your own literate collections), plus I also wanted to bring all the files to one format, namely FLAC - because New progressive programs (Ableton Live) and players (ipod (with special firmware, or touch with software / cowon) support it.



So, once again, the task is diskname.flac + diskname.cue, from them you need to get a lot of tracks with tags and distinct file names (Artist name, track number, track name) + playlist.



For example, I took the debian lenny distribution (5.0). Apparently, for * buntu users and other debian-based distributions, the commands will also be correct.



What we need:

')

sudo aptitude install build-essential - gcc and the necessary stuff to build support for ape format.

sudo aptitude install cuetools - for working with a cue file.

sudo aptitude install shntool - a set of utilities for cutting audio files and more.

sudo aptitude install wavpack - encoder and decoder for wavpack format

sudo aptitude install flac - encoder and decoder for flac



Downloading mac source (for working with ape)

wget supermmx.org/resources/linux/mac/mac-3.99-u4-b5.tar.gz

Unpack and go to the build directory:

tar xvzf mac-3.99-u4-b5.tar.gz

cd mac-3.99-u4-b5

make

if everything went smoothly - sudo make install.



So, everything is ready!

And now you need to write your script to automate the entire process. But wait, I've already sketched something;)

So, we will have three scripts.



Script for cutting the original into separate tracks and their subsequent tagging.



cuesplit

 #! / bin / bash 
 if ["$ 1" == ""];
 then
     echo "Usage: $ 0 flac / apefile cuesheetname"
     exit
 else
 cuebreakpoints $ 2 |  shnsplit -o flac -O always $ 1
 cuetag $ 2 split-track * .flac
 fi

Script to rename received tracks:

cuerename

 #! / bin / bash 

 TRACKNAME = split-track
 ENDNAME = ". Flac"
 PLAYLISTNAME = "! Playlist.m3u"

 rm $ PLAYLISTNAME 2> / dev / null

 for i in 01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 28 30 31 32 33 34 35 36 38 38 40 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66;  do

	 if [-f $ TRACKNAME $ i $ ENDNAME];
		 then
		 echo -n
		 else
		 exit
	 fi

	 PERFORMER = `cueprint -t '% p_ \ n' -n $ i $ 2 |  tr [: blank:] '_' |  tr ':' '_' |  tr '*' '_'`
	 TRACK = `cueprint -t '_% t \ n' -n $ i $ 2 |  tr [: blank:] '_' |  tr ':' '_' |  tr '*' '_'`
	 echo "$ PERFORMER $ i $ TRACK $ ENDNAME" >> $ PLAYLISTNAME
	 echo "$ PERFORMER $ i $ TRACK $ ENDNAME"
	 mv $ TRACKNAME $ i $ ENDNAME $ PERFORMER $ i $ TRACK $ ENDNAME

 done;

Explanation of the cycle. I needed the tracks to be called 01, 02, 03, for proper sorting, and not 1, 2, 3. On one of the discs there were 66 tracks (my favorite Mexicans) :)



A script that executes the first and second script in turn;)

cuemagic

 #! / bin / bash 
 if ["$ 2" == ""];
 then
     echo "Usage: $ 0 flac / apefile cuesheet-file"
     exit
 else
 cuesplit $ 1 $ 2
 cuerename $ 1 $ 2
 fi

According to statistics, most people are normal windows-users, respectively, there are spaces in the files.

I, unfortunately, a bad programmer (by education - a mining engineer). Therefore, for order and for my scripts to work at all, I wrote another small primitive script to replace spaces in the file name with underscores. I hope in the comments I will be prompted by a more elegant way.



Script for mass renaming files with spaces in the name.

mrnm

 #! / bin / bash. 
 find.  -depth | rename 's / \ / _ / g'

And now an example of work!

If you have any questions, please ask. Especially welcome rational suggestions and thoughts about the elegant solution to the problem with spaces and other special characters :)



ps When I finished the article, I noticed that such tags were already indicated by someone, looked for these tags, everything turned out well - the person had already written about this, but he had slightly different goals. In any case, this example can be a good example of how not to program or how amateurs program;)
