Commands tagged mp3

* grep -i leaves only mp3 files (case insentitive)

* sort -R randomizes list (may use GNU 'shuf' instead).

* the sed command will add double quotes around each filename (needed if odd characters are present)

This converts a mp3 file "infile" to a CBR 128 kbps high quality (according to Winamp) mp3 "128/outfile", joint-stereo, using LAME.

useful signals are:

TIP: use aliases or shortcuts to control mpg321 from the Desktop Manager

Assumes that the files are named as such: 01-Filename.mp3

If your files are named differently, change the number of periods in the sed 's/...\(.*\)/\1' bit to match the numbers of characters you need to cut off the front of the file.

Note: This only writes the titles.

Assumes that the files are named in numerical order (ie. 01 Filename.mp3). It will set the track number as tracknumber/totaltracks (ie. 1/14). This will write both ID3v1 and ID3v2 tags.

Note: This only writes the track numbers.

youtube-dl has this functionality built in. If you're running an older version of youtube-dl, you can update it using `youtube-dl -U` (although if you have an older version, it probably doesn't download youtube videos anyway.)

youtube-dl --help will show you other options that may come in useful.

Make your own MP3s from Youtube videos.

Recursively download all files of a certain type down to two levels, ignoring directory structure and local duplicates.

Usage:

wgetall mp3 http://example.com/download/

umph is parsing video links from Youtube playlists ( http://code.google.com/p/umph/ )

cclive is downloading videos from Youtube ( http://cclive.sourceforge.net/ )

Example:

Gives stereo, 16bit, 44.1kHz (default in Ubuntu/Medibuntu ffmpeg).

-aq 2 = 220-250kbit/s VBR, lower number is better quality. 2 or 3 should be good for most people. If you want the best mp3 q you should remove -aq and use -ab 320k to get 320kbit/s, but that is probably overkill for most .flv videos.

squeezed the monster (and nifty ☺) command from 7776 from 531 characters to 284 characters, but I don't see a way to get it down to 255. This is definitely a kludge!

Maybe it could work for any music player if you change "audacious2" with the string you see in `ps aux` for your player. Needs testing in different systems.

Some MP3s come with tags that don't work with all players. Also, some good tag editors like, EasyTAG output tags that don't work with all players. For example, EasyTAG saves the genre as a numeric field, which is not used correctly in Sansa MP3 players.

This command corrects the ID3 tags in MP3 files using mid3iconv, which comes with mutagen. To install Mutagen on Fedora use "yum install python-mutagen"

Creates a 5 minute flv file, with the given sequence of images and audio with 0.5 fps.

The images were created using the following command:

for x in `seq 0 300`; do cp ../head.PNG head-`printf '%03d' $x`.png; done

You can also inject metadata to seek easier using yamdi as follows:

yamdi -i muxed.flv -o video.flv

A short variant if you have only one directory whit only audio files in it.

Supports other file formats.

find . -type f -iname '*.flac' # searches from the current folder recursively for .flac audio files

| # the output (a .flac audio files with relative path from ./ ) is piped to

while read FILE; do FILENAME="${FILE%.*}"; flac -cd "$FILE" | lame -b 192 - "${FILENAME}.mp3"; done

# for each line on the list:

# FILE gets the file with .flac extension and relative path

# FILENAME gets FILE without the .flac extension

# run flac for that FILE with output piped to lame conversion to mp3 using 192Kb bitrate

This heavy one liner gets all the files in the "/music/dir/" directory and filters for non 44.1 mp3 files. After doing this it passes the names to sox in-order to re-sample those files. The original files are left just in case.

Gets the latest podcast show from from your favorite Podcast. Uses curl and xmlstarlet.

Make sure you change out the items between brackets.

Ever wanted to stream your favorite podcast across the network, well now you can.

This command will parse the iTunes enabled podcast and stream the latest episode across the network through ssh encryption.

Grab a list of MP3s (with full path) out of Firefox's cache

Ever gone to a site that has an MP3 embedded into a pesky flash player, but no download link? Well, this one-liner will yank the *full path* of those tunes straight out of FF's cache in a clean list.

Shorter and Intuitive version of the command submitted by (TuxOtaku)

Ever gone to a site that has an MP3 embedded into a pesky flash player, but no download link? Well, this one-liner will yank the names of those tunes straight out of FF's cache in a nice, easy to read list. What you do with them after that is *ahem* no concern of mine. ;)
