Manuals

Sometimes it’s really hard to find just that piece of information one needs to get done with the work. Searching a program’s homepage, looking around in the uncountable forums or playing with the settings can be very time consuming. On one of that journeys I passed by a site which I have seen before but did not remember: http://en.flossmanuals.net/“Free manuals for free software”. Concerning music making I was happy to see the new Ardour manual and an Audacity manual.

There are many more documents about streaming, video editing and graphic design software, general Linux commands and other. The site is nicely made, very appealing to the eye and comes as well in other languages than English, however not all of the manuals are translated. Maybe YOU want to supply one?

using sound effects in ardour

To use LADSPA effects in ARDOUR projects one can just add one from the list by double-clicking in the field above the volume control in the mixer panel. But sometimes you want to use the same effect on different tracks or mix the original with the effect. If there is no Dry/Wet-mix control in the effect plug-in the latter can be done via SEND-effects. Adding the same effect to different tracks through a SEND plug-in, CPU usage is smaller than adding it to every single track. Although, once you know how it works it is quite straightforward, but I struggled a lot getting it to work.

To do so one adds a bus to the mixer panel. Then a SEND plugin is chosen by right-clicking in the effect field of the desired audio track. This plug-in can be attached to another track or bus  where one can add effects in the usual way. The important trick which finally does the job and which took  me a while to figure out is to activate the SEND connection in its context menu.by right-clicking on it. In the menu you find a activate command.

From now on all pre-fader signals from the chosen track go into the chosen bus where effects can be added. Pre fader means that you can change the volume of the original track (or even turn it down to mute) and he signal is still received by the effect bus. If the SEND is added into the field below the volume control it is a post fader send and the signal goes to the effect bus filtered.

The picture shows an actived SEND in an audio track. The levels of Bus 3 show that the signal is received.

eeepc as a linux audio workstation

A few days ago I told you about the first steps into using an eeepc as a real-time audio tool. jack runs up fine. I chose the internal audio card with the combination 48kHz,  256frames, 4buffers (which gives a latency of  21.3msec) and running on its  own  it doesn’t cough up any xrun.

I couldn’t get sooperlooper working yet. Sooperlooper works (see solution)! freqtweak works  (A nice little thing!), too.  Ardour works very nice, too. Sometimes the screen is a bit small for the whole window, but  I was using ardour a bit today and it wasn’t too much of  a hassle. Audacity is buggy (converting to mono + playing results in a segmentation fault).

I will try and find out about sooperlooper and audacity. Other programs and how an external audio card  connects  (I hope  my older posts will tell me what to do), a midi interface and all that will come up soon…
