  • The Piano Phase piece, by Steve Reich is a minimalist composition which is played on two pianos played at slightly different tempos, a task that's very difficult to accomplish by human players. The auditive effects produced by the cell displacement produce beautiful patterns. See https://en.wikipedia.org/wiki/Piano_Phase . My rendered version: https://ydor.org/SteveReich/piano_phase.mp3 Requires sox to be installed on the system. There are multiple videos on youtube showing different approaches and experiences to this interpretation. There is also a synthesized version. Even if Bash can behave as a powerful pianist, a simple threaded version leaves full room to several time glitches and even negative displacements, the same issues that human pianists experience when playing the piece. The older the computer, the better the chaos added to the result due to the CPU load. Apparently that's the reason Steve Reich composes pieces such as this. Without further ado, please give a warm welcome to the Bash minimalist player on synthesized two-threaded pianos. Please turn off your cellphones.

  • This commands does just two things: fakes user agent (the one was taken from recent Android app) and sends the (possibly) listener ID (it can be any - I put "1" here because it works like a charm - after the name of stream ?1 as you can see). Look for the list of stations here: http://pub7.di.fm Or here: https://goo.gl/pdhhpQ Best regards, sxiii :) Show Sample Output

  • This will download all files of the type specified after "-A" from a website. Here is a breakdown of the options: -r turns on recursion and downloads all links on page -l1 goes only one level of links into the page(this is really important when using -r) -H spans domains meaning it will download links to sites that don't have the same domain -nd means put all the downloads in the current directory instead of making all the directories in the path -A mp3 filters to only download links that are mp3s(this can be a comma separated list of different file formats to search for multiple types) -e robots=off just means to ignore the robots.txt file which stops programs like wget from crashing the site... sorry http://example/url lol..

  • This command will place symbolic links to files listed in an m3u playlist into a specified folder. Useful for uploading playlists to Google Music. prefix = The full path prefix to file entries in your .m3u file, if the file paths are relative. For example, if you have "Music/folder/song.mp3" in your list.m3u, you might want to specify "/home/username" as your prefix. list.m3u = Path to the playlist target_folder = Path to the target folder in which you would like to create symlinks

  • This is a very simple and lightweight way to play DI.FM stations For a more complete version of the command with proper strings in the menu, try: (couldnt fit in the command field above) zenity --list --width 500 --height 500 --title 'DI.FM' --text 'Pick a Radio' --column 'radio' --column 'url' --print-column 2 $(curl -s http://www.di.fm/ | awk -F '"' '/href="http:.*\.pls.*96k/ {print $2}' | sort | awk -F '/|\.' '{print $(NF-1) " " $0}') | xargs mplayer This command line parses the html returned from http://di.fm and display all radio stations in a nice graphical menu. After the radio is chosen, the url is passed to mplayer so the music can start dependencies: - x11 with gtk environment - zenity: simple app for displaying gtk menus (sudo apt-get install zenity on ubuntu) - mplayer: simple audio player (sudo apt-get install mplayer on ubuntu) Show Sample Output

  • Press > or < to go to the next or previous track. Space to toggle play/pause, etc. It creates a temp file descriptor. To see where the file descriptor gets created type: echo <(echo foo) This works better than running find first, then piping to mplayer with xargs or something, because that won't let you use keyboard shortcuts.

  • This normalizes volume in your mp3 library, but uses mp3gain's "album" mode. This applies a gain change to all files from each directory (which are presumed to be from the same album) - so their volume relative to one another is changed, while the average album volume is normalized. This is done because if one track from an album is quieter or louder than the others, it was probably meant to be that way.

    find . -type f -name '*.mp3' -execdir mp3gain -a '{}' +

  • The only zipped version of an album available for download is the lossy mp3 version. To download lossless files, because of their size, you must download them individually. This command scrapes the page for all the FLAC (or also SHN) files.

  • Execute this in the root of your music library and this recurses through the directories and normalizes each folder containing mp3s as a batch. This assumes those folders hold an album each. The command "normalize-audio" may go by "normalize" on some systems.

    find . -type d -exec sh -c "normalize-audio -b \"{}\"/*.mp3" \;
