Free audio convert software for linux

Audio Convert is a script to convert Wav, Ogg, MP3, MPC, FLAC, APE, or WMA files into Wav, Ogg, MP3, MPC, FLAC, or APE files.
It has an easy-to-use interface that makes it possible to fill in the tags for a few formats and choose the quality of compression.
The script was initially designed for the nautilus file browser, and can be easily installed into nautilus by copying it to the nautilus-scripts directory, at which point you can right click on the desired audio file(s) and choose "audio-convert" from the "scripts" menu.
The script is also known to work on rox or directly from a shell.
Enhancements:
- The installer was modified to create the directory it is supposed to create.

AudConvert is an application that is designed to take any audio format and convert it to any other audio format.
The idea for AudConvert came from my need to turn my Ogg Vorbis collection into MP3s for portable devices.
Yes, this process sometimes will result in lower quality, but sometimes it must be done.
Main features:
- Input any directory of files, get out the same directory structure (or flat directory) of newly encoded files.
- Multi-threaded: Encode up to 8 files simultaneously.
This is the first release of this software and it needs a lot of testing.
Supported Inputs:
- Ogg Vorbis (oggdec)
- MP3 (mpg123)
- FLAC (flac)
Supported Outputs:
- Ogg Vorbis (oggenc)
- MP3 (lame)

Audio Format Converter is a an Amarok script that allows you to convert the audio format of the tracks in the playlist. The script takes a snapshot of the current playlist. Once the conversion has started, you can go back to using amaroK normally.

Supported files for both input and output include .flac, .ogg, .mp3, .mpc, .m4a, and .wav. Additionally, .wma, .ra, and are supported for input. (See below for the required packages.)

I dont know how to do anything with metatags from .wma or .ra. All I know is tags will get transferred to the output file if and only if the tags show up in the amaroK playlist. If they arent there, I suggest converting the files, then using a real tag editor like Easy Tag to put them in to the converted files.

This has only been tested on amaroK 1.2.4, but it should work on any amaroK>=1.2

The original files are NOT deleted. If the output file will overwrite an existing file, a dialog will appear to ask you whether to go ahead and overwrite or to skip the track. If you try to convert a file into the format its already in, a dialog will ask you how to handle this situation.

Depending on the number of tracks and the speed of your computer, this can take a long time to run. With each track, a passive popup will let you know what track its processing. At any time, you can stop the script by clicking stop in the amaroK script GUI.

Convert::Cyr, chcp is a Perl module for change cyrillic code page of a text.

SYNOPSIS

use Convert::Cyr qw(chcp); $converted_string=chcp($string, $maxlen, $from, $to);

ABSTRACT

Convert::Cyr, chcp - change cyrillic code page of a text.

chcp takes as the first argument a string that is to be converted. It returns the converted string. Second argument is the lenght of the string. Third is source codepage. Forth is target codepage.

Original description from PHP function:

convert_cyr_string (string str, string from, string to) "This function returns the given string converted from one Cyrillic character set to another. The from and to arguments are single characters that represent the source and target Cyrillic character sets."

The supported types are: k - koi8-r w - windows-1251 i - iso8859-5 a - x-cp866 d - x-cp866 m - x-mac-cyrillic

HTML Code Convert helps speed up the conversion of HTML code into different format including Java Script, JavaServer Pages, Microsoft ASP, PHP, Perl, Python, and the UNIX Shell. It is particularly useful in CGI scripting.
Enhancements:
- Colors and font selected in prefeferences box.
- Fixe bug with Quit button. First try to support accessibility.
- Updated schemas.

Q-Audio is a digital audio interface for Q. Q-Audio project contains three modules which together provide the basic functionality needed to write digital audio applications.
The audio module implements a (nearly) real-time audio interface on top of the PortAudio library. The sndfile module allows you to access sound files in various formats using libsndfile.
The wave module provides basic operations for creating and manipulating wave data, including operations to convert sample rates, to calculate Fourier transforms, and to display wave data in a GGI visual.
About Q language:
Q is a functional programming language based on term rewriting. Thus, a Q program or "script" is simply a collection of equations which are used to evaluate expressions in a symbolic fashion. The equations establish algebraic identities and are interpreted as rewriting rules in order to reduce expressions to "normal forms". For instance, here is how you define a function sqr which squares its argument by multiplying it with itself:
sqr X = X*X;
Note that, as in Prolog, capitalized identifiers are used to indicate the variables in an equation, which are bound to the actual values when an equation is applied. Equations may also include a condition part, as in the following definition of the factorial function:
fact N = N*fact (N-1) if N>0;
= 1 otherwise;
Functions on structured arguments are defined by "pattern matching". E.g., the product of a list (denoted in Prolog-like syntax) can be computed with these two equations:
prod [] = 1;
prod [X|Xs] = X*prod Xs;
With this definition, the factorial can now also be defined as follows (the notation [1..N], as in Haskell, denotes an arithmetic sequence):
fact N = prod [1..N];
As you can see, the definitions are really just like mathematical equations. The syntax is superficially similar to other modern functional languages like Miranda and Haskell, except that Q is "free-format", i.e., it does not use layout to indicate syntactical structure (thus the semicolon is used to terminate an equation).
Due to its term rewriting heritage, Q goes well beyond most other functional languages in that it also allows you to perform computations with symbolic expressions. For instance, with the definition of the sqr function from above, you will find that sqr (X+1) evaluates to (X+1)*(X+1). This might first look like an arcane feature, but it is actually quite useful, because you can try your definitions with symbolic inputs, too.
Enhancements:
- src/wave.c: minor fixes for compatibility with latest gcc versions

Rainbyte Video Converter is a Kommander script which helps you convert video and audio in an easy way.

Its based on Kommander, mencoder and ffmpeg and you can convert from/to any format supported by those programs.

Well, I hope that it will be usefull for you, thanks for all.

Convert::RACE is a conversion between Unicode and RACE.

SYNOPSIS

use Convert::RACE;

$domain = to_race($utf16str);
$utf16str = from_race($domain);

This module provides functions to convert between RACE (Row-based ASCII-Compatible Encoding) and Unicode Encodings.

RACE converts strings with internationalized characters into strings of US-ASCII that are acceptable as host name parts in current DNS host naming usage.
