Free volume software for linux

Volume.app is a small graphical software utility enabling quick and convenient control of a computers audio volume level. Volume.app is intended for use on Linux/Unix systems in conjunction with an X window manager that supports dockable applications ("dockapps") such as AfterStep, BlackBox, or Window Maker.

It is a refinement of an idea that first appeared in Timecops WMix: a user interface comprising a "knob" that can be interactively "turned" by clicking and dragging the mouse. I found this approach quite appealing, both from an aesthetic viewpoint, and (more importantly) from a user-interface perspective.

A handful of other dockapp volume control programs are out there, and I have tried many of them. An interface element present in most of these is some form of "slider" as the primary means of adjusting the volume. (A fictitious example may be seen at right). To my dismay, with this kind of interface, volume adjustments tended to be large and abrupt. Because the slider was so small, raising or lowering the volume "just a bit" required extremely careful control of the mouse-- a slip of the hand had the potential to spike the volume to full blast. (I have a set of Altec-Lansing ACS48 speakers which make this a rather unpleasant experience). This approach left much to be desired.

I longed for an alternative, and upon playing with WMix (pictured at left) I had found it. The knob was genius in that it provided a means of graphically adjusting the volume, as a slider would, without tying itself directly to the motion of the mouse. The basic mode of usage is identical: you click on the thing and drag the mouse up or down. However, with the knob, the range of motion need not be confined to the postage-stamp-sized area of the dockapp. The mouse travel needed to cover the entire range of volume settings can be made longer, on the order of the full height of the screen-- almost like a much larger, easier-to-use slider. No longer were precise movements needed to make volume adjustments!

Still, I found WMixs interface to be a bit busy (never was a fan of tiny little buttons) and the all-important knob was yet a rather small target to find with the mouse. So, I grabbed a copy of the WMix source code, and rebuilt it into a dockapp that had a much larger knob as its sole interface element. I dubbed it Volume.app, and have placed it here for the benefit of everyone.

GKrellM Volume is a plugin which controls the sound mixer device of your choice.
The plugin will run if you have at least version 2.0.1 of gtk and version 2.0 of gkrellm
alsa:
Compile with:
make enable_alsa=1
The plugin will prefer alsa and fall back to oss when there is no alsa support.
i18n:
Compile with:
make enable_nls=1
And install with
make enable_nls=1 install
Enhancements:
- Brown paper bag bug in alsa backend introduced in the previous version.

The volume normalizer plugin is an XMMS plugin that is used to give all songs the same volume level so that you wont need to play with the volume knob whenever a song changes.
Enhancements:
- Fixed build issues to make it build on x86-64 and detect missing xmms-devel files.

Thunar Volume Manager project provides automatic management of removable media and drives for the Thunar File Manager.

The Thunar Volume Manager is an extension for the Thunar file manager, which enables automatic management of removable drives and media. For example, if thunar-volman is installed and configured properly, and you plug in your digital camera, it will automatically launch your preferred photo application and import the new pictures from the camera into your photo collection.

The advantage of Thunar Volume Manager over other solutions (like gnome-volume-manager or ivman) is that it does not require an additional daemon to be running in the users desktop session, which means it is very lightweight solution. In addition, the Thunar Volume Manager smoothly integrates into the Thunar file manager and the Xfce desktop.

Polypaudio Volume Control (pavucontrol) is a simple GTK based volume control tool ("mixer") for the PulseAudio sound server.

In contrast to classic mixer tools this one allows you to control both the volume of hardware devices and of each playback stream seperately.

Audio::TagLib::ID3v2::RelativeVolumeFrame is an ID3v2 relative volume adjustment frame implementation.

SYNOPSIS

use Audio::TagLib::ID3v2::RelativeVolumeFrame;

my $i = Audio::TagLib::ID3v2::RelativeVolumeFrame->new(
Audio::TagLib::ByteVector->new(""));
$i->setChannelType("MasterVolume");
print $i->channelType(), "n"; # got "MasterVolume"

This is an implementation of ID3v2 relative volume adjustment. The presense of this frame makes it possible to specify an increase in volume for an audio file or specific audio tracks in that file.

Multiple relative volume adjustment frames may be present in the tag each with a unique identification and describing volume adjustment for different channel types.

new()

Constructs a RelativeVolumeFrame. The relevant data should be set manually.

new(ByteVector $data)

Constructs a RelativeVolumeFrame based on the contents of $data.

DESTROY()

Destroys the RelativeVolumeFrame instance.

String toString()

Returns the frames identification.

see identification()

LIST channles()

Returns a list of channels with information currently in the frame.

NOTE This should be a list of PV which indicates the ChannelType.

see %_ChannelType

PV channelType()

Always returns master volume.

deprecated

void setChannelType(PV $t)

This method no longer has any effect.

deprecated

IV volumeAdjustmentIndex(PV $type = "MasterVolume")

Returns the relative volume adjustment "index". As indicated by the ID3v2 standard this is a 16-bit signed integer that reflects the decibils of adjustment when divided by 512.

This defaults to returning the value for the master volume channel if available and returns 0 if the specified channel does not exist.

see setVolumeAdjustmentIndex()

see volumeAjustment()

void setVolumeAdjustmentIndex(IV $index, PV $type = "MasterVolume")

Set the volume adjustment to $index. As indicated by the ID3v2 standard this is a 16-bit signed integer that reflects the decibils of adjustment when divided by 512.

By default this sets the value for the master volume.

see volumeAdjustmentIndex()

see setVolumeAdjustment()

< NV volumeAdjustment(PV $type = "MasterVolume") >

Returns the relative volume adjustment in decibels.

NOTE Because this is actually stored internally as an "index" to this value the value returned by this method may not be identical to the value set using setVolumeAdjustment().

This defaults to returning the value for the master volume channel if available and returns 0 if the specified channel does not exist.

see setVolumeAdjustment()

see volumeAdjustmentIndex()

void setVolumeAdjustment(NV $adjustment, PV $type = "MasterVolume")

Set the relative volume adjustment in decibels to $adjustment.

By default this sets the value for the master volume.

NOTE Because this is actually stored internally as an "index" to this value the value set by this method may not be identical to the one returned by volumeAdjustment().

see setVolumeAdjustment()

see volumeAdjustmentIndex()

PeakVolume peakVolume(PV $type = "MasterVolume")

Returns the peak volume (represented as a length and a string of bits).

This defaults to returning the value for the master volume channel if available and returns 0 if the specified channel does not exist.

see setPeakVolume()

setPeakVolume(PeakVolume $peak, PV $type = "MasterVolume")

Sets the peak volume to $peak.

By default this sets the value for the master volume.

see peakVolume()

%_ChannelType

This indicates the type of volume adjustment that should be applied. keys %Audio::TagLib::ID3v2::RelativeVolumeFrame::_ChannelType lists all available values used in Perl code.

Normalize is a tool for adjusting the volume of audio files to a standard level. This is useful for things like creating mixed CDs and mp3 collections, where different recording levels on different albums can cause the volume to vary greatly from song to song.
Installation instructions:
1. ./configure options
2. make
3. make install
See the file INSTALL for more extensive directions. See the man page, normalize.1, for usage. Run "./configure --help" for configure options.
Enhancements:
- Fixed bug with reading broken wav files with bad sizes
- Fixed bug causing seg fault on non-PCM wav files
- Fixed bug with reading wav files that have stuff after the data chunk
- Fixed Windows "no such file" bug
- Fixed small memory leak
- Fixed cosmetic bug with negative gains
- Fixed bad basename regexp in normalize-mp3 script
- Fixed --oggdecode option in normalize-mp3 script
- Turned audiofile support on by default
- Upgraded to latest GNU autotools
