Free convert audio files software for linux

Mobilizer project is a Firefox extension lets you easily send your pictures, video, audio files and text from the web to most cell phones in the US. With the Mobilizer installed, simply right-click on a web page or media file, tell us what mobile phone number(s) you want to receive the media, and Mixxer will automatically re-format and deliver the media to those cell phone(s).

You can either select “Mobilize This!” to send the particular media file you are pointing to, or select “Mobilize All!” to choose from all the media files on the page. In cases where the media is embedded (such as flash) and you can’t right-click, hover over it and a Mobilizer link will appear above the media...

Mixxer’s Mobilizer browser extension, and conversion and delivery service, works with just about any wireless carrier in the U.S. and are FREE. Please note, however, that wireless carriers may charge extra for text messaging (SMS or MMS) or accessing the Internet.

Nautilus-audio-convert is an extension of the Gnome desktop manager Nautilus. nautilus-audio-convert introduces contextual menus hen clicking on an audio file.

Audio::File is a audio file abstraction library.

SYNOPSIS

use Audio::File;
my $file = Audio::File->new( "foo.bar" );

print "The ". $file->type() ."-file ". $file->name
." is ". int $file->length() ." seconds long.n";

print "Its interpreted by ". $file->tag->artist()
." and called ". $file->tag->title() ".n";

Audio::File abstracts a single audio file, independant of its format. Using this module you can access a files meta-info like title, album, etc. as well as the files audio-properties like its length and bitrate.

Currently only the formats flac, ogg vorbis and mp3 are supported, but support for other formats may be easily added.

Audio::File::AudioProperties is a Perl module that can abstract an audio files audio properties.

Audio::File::AudioProperties is the base class for other file format independant audio property classes like Audio::File::Flac::AudioProperties or Audio::File::Ogg::AudioProperties. You should not use this class yourself exept youre writing an own file format dependant subclass.

METHODS

new

Constructor. Creates new Audio::File::AudioProperties object. You shoud not use this method yourself. Its called by the filetype-dependant subclasses of Audio::File::Type automatically.

init

Initializes the object. Its called by the constructor and empty by default. Its ought to be overwritten by subclasses.

length

Returns the length of the audio file in seconds.

bitrate

Returns the bitrate of the file.

sample_rate

Returns the sample rate of the audio file.

channels

Returns the number of channels the audio file has.

all

Get all audio properties.

Audio::File::Type represents an audio filetype.

An instance of an object inherited from Audio::File::Type is returned by the constructor of Audio::File. This object currently provides access to the audio files information like its audio properties (bitrate, sample rate, number of channels, ...) and the data stored in the files tag, but also providing access to the raw audio data and other information should be easy to be implemented.

METHODS

new

Constructor. In fact you dont need to use it. Please use Audio::File which will call the appropriate constructor corresponding to the files type.

init

This method will be called by the constructor. Its empty by default and should be overwritten by inheriting subclasses to initialize themselfes.

name

Returns the name of the audio file.

is_readable

Checks whether the file is readable or not. At the moment its only used by the constructor, but it will be more usefull with later versions of Audio::File.

is_writeable

Checks whether the file is writeable or not. At the moment youll probably dont need to call this method, but itll be more usefull as soon as changing the audio file is implemented.

tag

Returns a reference to the files tag object. See the documentation of Audio::File::Tag to learn about what the tag object does.

audio_properties

Returns a reference to the files audio properties object. See the documentation of Audio::File::AudioProperties to get information about what the audio properties object does.

save

Saves the audio file. This is not yet implemented but it should remember me to do it at some time..

type

Returns the files type.

The Audio File Library provides a uniform and elegant API for accessing a variety of audio file formats, such as AIFF/AIFF-C, WAVE, NeXT/Sun .snd/.au, Berkeley/IRCAM/CARL Sound File, Audio Visual Research, Amiga IFF/8SVX, and NIST SPHERE. Supported compression formats are currently G.711 mu-law and A-law and IMA and MS ADPCM.

Key goals of the Audio File Library are file format transparency and data format transparency. The same calls for opening a file, accessing and manipulating audio metadata (e.g. sample rate, sample format, textual information, MIDI parameters), and reading/writing sample data will work with any supported audio file format. Likewise, the format of the audio data presented to the application need not be tied to the format of the data contained in the file.

movemetafs is a searchable filesystem metadata store for Linux that lets users tag local files (including image, video, audio, and text files) by simply moving the files to a special folder using any file manager.
It also lets users find files by tags using a boolean search query. The original files (and their names) are kept intact. movemetafs doesnt have its own user interface, but it is usable with any file manager.
In the name `movemetafs, `metafs means filesystem metadata store, and move refers to the most common way tags are added or removed: the user moves the file to be acted on to the `meta/tag/$TAGNAME or
`meta/untag/$TAGNAME special folder. When the target folder is such a special folder, the file is not removed from its original location (meta/root/**/*).
movemetafs is similar to LAFS (http://junk.nocrew.org/~stefan/lafs/)
(not tagji 1.1 by Manuel Arriaga). Most important differences:
- movemetafs uses MySQL instead of PostgreSQL (benefits: speedup, easier installation with pts-mysql-local).
- movemetafs doesnt require files to be explicitly added.
- movemetafs cannot list all untagged files quickly.
- movemetafs is written in Perl, so it is quite easy to extend and try out new features.
- movemetafs continues to work when files are renamed.
- movemetafs works with files with more than one hard link.
Main features:
- Use any file manager to tag files: move the file to the `meta/tag/$TAGNAME or `meta/tagged/$TAGNAME folder. The file is not removed from its original folder.
- Use any file manager to untag files: move the file to the `meta/untag/$TAGNAME. The file is not removed from its original folder.
- Specify search query by changing to the invisible `meta/search/$QUERYSTRING folder. Results are symbolic links into `meta/root.
- If you want to search for only a single tag, list the folder `meta/tagged/$TAGNAME. Results are symbolic links into `meta/root.
- Alternatively, you untag a file by removing the symlink `meta/tagged/$TAGNAME/$FILENAME.
- Alternatively, use POSIX extended attributes to retrieve (or even set) the tags associated to a file.
- Attach textual descriptions to files, and read the description once the file is found.
- Use POSIX extended attributes to get and set the textual description of a file.
- Create a recursive POSIX extended attribute dump (of tags and descriptions) from the database very quickly.
- Restore the created POSIX extended attribute dump with `setfattr --restore.
- Use versatile search query syntax (MySQL fulltext search) with the possiblity of boolean search (i.e. searching for files matching a combination of tags).
- Copy search results to make backups or to create collections.
- Searching is fast, because it uses a fulltext index.
- After installation, movemetafs can be used on an existing filesystem instantly: there is no migration needed to make an existing filesystem usable with movemetafs: data doesnt have to be copied, moved, touched etc.
- Untagged files dont have any negative effect on the speed of movemetafs, even if the filesystem contains millions of files.
- movemetafs nicely survives a system crash: non-cache data is stored in MySQL InnoDB tables (which use journaling), and even if the whole tag database is lost, the original filesystem remains usable without movemetafs.
- Stores tags in twice: once in a fulltext indexed column in a MyISAM table, and once in an InnoDB relational table. Uses the fast MyISAM table for searches, and the InnoDB table for data recovery.
- Treats file names as opaque 8-bit strings, thus it works with any filesystem character set, even when character sets are mixed in the middle of the filename.
- Uses UTF-8 for tag names and descriptions.
- Filenames in search results are automatically made unique when necessary.
- Following the Unix filesystem design, files with multiple hard links share a commond description and a common set of tags. If tags or the description are changed on one name, the changes also apply to other names, too.
