a utility to connect and disconnect two existing ports on ALSA
sequencer system. The ports with the arbitrary subscription permission
can be connected to any (MIDI) device ports using aconnect.
aconnect [-d] [-options]
sender
receiver
aconnect
-i|-o [-options]
aconnect
-x
Connection
Management options:
-d, --disconnect Disconnect
the given subscription.
-e, --exclusive
Connect ports with exclusive mode.
Both sender and receiver ports can be no longer connected by any other
ports.
-r, --real
queue Convert time-stamps of
event packets to the current value of the given real-time
queue. This is option is, however, not so useful, since the
receiver
port must use (not necessarily own) the
specified queue.
-t, --tick
queue Like -r option, but
time-stamps are converted to the current value of the given tick
queue.
Options to list ports:
-i,
--input List existing input (readable) ports.
This option is exclusive to -o.
-o, --output
List existing output (writable) ports. This
option is exclusive to -i.
-l, --list
List the current connection status. The
connected and connect- ing ports from/to each port are listed together.
The suffix flag [ex] means the connection is
exclusive.
The
suffix flag [real:#]
and [tick:#] mean the connection
includes real-time and tick conversion on the listed queue,
respectively.
Remove all connections option:
-x, --removeall
Remove all exported connections.
KAConnect:
displays the readable and writable ports of the ALSA sequencer system.
Connections between those ports can be subscribed by highlighting one
port in the list of readable ports and one port in the list of writable
ports and then mouse-clicking on "connect". Disconnecting works the
same
way, but with mouse-click on "disconnect". The height of the listboxes
can be configured using the --height option. It updates the
lists when ALSA clients,which implement readable/writable ports, are
started or terminated. The display of subscribed connections is also
updated whenever a new client is started or a new started or a new
subscription is performed.
KWaveview: real time scope and spectrum analyser.KWaveView
captures sound from "Line In" or "Mic In" and displays the sound waves
in the time domain and Fourier domain. The sound data can be displayed
in the temporal as well as the Fourier domain. Both the scope and the
spectrum analyser can display two channels simultaneously, which can be
selected from your input channels. Frequency areas can be enlarged in
the spectrum view. The lower frequency boundary is determined by
clicking the left mouse button in the spectrum view. Right clicking in
the spectrum view determines the higher frequency boundary. Toggling
between full frequency view and enlarged view is done by clicking the
middle mouse button in the spectrum view. When moving the mouse in the
spectrum, the frequency at the mouse cursor is displayed. For this
feature to work also exactly in the enlarged view, please make sure,
not to change the number of frames and the window size after you
determined the boundaries for the enlargement. Otherwise you'll get
roundoff errors due to the conversion between mouse coordinates
and frequency channels.
Ladcca

Recording:
- Mic. in:
When setting up a microphone for recording, you should check it is
plugged into the microphone input on the soundcard
(third socket from the end, as opposed to the line in, which is for
signals that have already been pre-amplified).
Next, use the mixer to check that the
recording box is checked
under
"Mic" and that the gains for "Vol" and "IGain"
are both non-zero (it's a good idea to turn them full on).
- Line in:
Signals that have been pre-amplified, such as those from the output of
a soundcard or the Sony mixing desk, should be fed into the line
input on the soundcard
(second from the end, after digital output).
With the mixer you should check that the recording box is
checked under
"Line" and that the gains for "Vol" and "IGain" set.
- rec: a
linux command-line utility for capturing the soundcard input from a mic
or a line into a standard format file,
e.g., rec

alsamixer GUI: alsamixer
is an ncurses mixer program for use with the ALSA
soundcard drivers. It supports multiple soundcards with multiple
devices.
Invoke by typing alsamixer
[options] , where
options could be
-h, -help
-c <card number
or idenfication> Select the
soundcard to use, if you have more than one. Cards are numbered from 0
(the default).
-D <device
identification> Select the mixer device
to control.
-g <toggle color
settings> Toggle the using of
colours.
-s <minimise
mixer window> Minimise the mixer
window.
Alsamixer recognises the
following keyboard commands to control the
soundcard.
- General Controls : The Left
and right arrow keys are used to select the channel (or
device,
depending on your preferred terminology). You can also use n
("next") and p ("previous"). The UpDown Arrows
control the volume for the currently selected device. You can also use +
or - for the same purpose. Both the left and right signals are
affected. For independent left and right control, see below. The B
or = key adjusts the balance of volumes on left and right chan-
using Insert (or ;) and Delete (or ')
respectively. L re-draws the screen.
- Quick Volume Changes:
PageUp
increases volume by 5, PageDown
decreases volume by 5 and End sets volume to 0. You can
also control left & right levels for the current channel
independently, as follows:
[Q
| W | E ] -- turn UP [ left
| both | right ]
[Z
| X | C ] -- turn DOWN [
left | both | right ]
If the
currently selected mixer channel is not a stereo channel, then all UP
keys will work like W, and all DOWN keys
will work like X.
- Exiting: Quit
the program with ALT Q, or by hitting ESC.
Please note that you might need to hit ESC twice on some
terminals since it's regarded as a prefix key.
Alsamixer GUI is a graphical user
interface which provides the same
functionality as alsamixer.
