Free recorder software for linux

KHdRecord is an audio recorder which writes directly to the harddisk.

This enables recording of LPs.

Encoding MP3-files uses a lot of computing resources. This program requires a 350 MHz CPU minimum to run. Encoding Ogg/Vorbis-files uses even more resources. On my 1.4GHz Pentium it takes half of the CPU time.

The program directly accesss the sound and the mixer device. If you use it as non-root, these devices must be accessible for the user.

Because /dev/dsp and /dev/mixer are symbolic links on the most systems, the devices behind the links must be accessible.

On most machines this are /dev/dsp0 and /dev/mixer0. To give the devices accessible log in as root. Enter chmod 777 /dev/dsp0 and chmod 777 /dev/mixer0 .

qt-recordmydesktop is a recordMyDesktop GUI created in QT language for the KDE desktop.

recordMyDesktop is a desktop session recorder for GNU/linux that attemps to be easy to use, yet also effective at its primary task.

As such, the program is separated in two parts; a simple command line tool that performs the basic tasks of capturing and encoding and an interface that exposes the program functionality in a usable way.

SoundTracker is a music tracking tool for X11 / Unix similar in design to the DOS program FastTracker and the Amiga legend ProTracker. Samples can be lined up on tracks and patterns which are then arranged to a song.

Supported module formats are XM and MOD; the player code is the one from OpenCP. A basic sample recorder and editor is also included. SoundTracker is free ("open source") software, licensed under the GNU GPL.

The basic concept is very simple: you have a number of sound samples, and you can arrange them on so-called tracks. A track (also called "channel") can not play more than one sample at the same time. Whereas the original Amiga trackers only provided four tracks (this was the hardware limit), modern trackers can mix a virtually unlimited number of channels into one sound stream, applying various effects to the samples used.

Tracks which are played at the same time are grouped to form a pattern. A pattern typically has 64 entries per track; these entries are cycled through at equidistant time intervals. A basic drum set could thus be arranged by putting a bass drum at entries 0, 4, 8, 12 etc. of one track and putting some hihat at entries 2, 6, 10, 14 etc. of a second track. Of course you can also interleave bass and hats on the same track, if the samples are short enough -- they cant overlap, otherwise the previous sample is stopped when the next one sets in -- look at the screen shots for a more visual explanation.

Finally, a module is a compact file containing various patterns and samples, including a position list which specifies playback order of the patterns, forming a song. SoundTracker can load modules of the popular XM and MOD formats. The also very popular IT format is not supported at the moment.
