8 <title>What's Different about Ardour</title>
10 If you are someone who has used other audio software, particularly
11 software generally referred to as a Digital Audio Workstation (or
12 "DAW"), then there will be a number of things about Ardour that may
13 puzzle you on your initial and early encounters with the program.
16 <section id="no-default-session">
17 <title>No default session</title>
19 You must explicitly create a
20 <glossterm linkend="gt-session">Session</glossterm> before you can do
21 anything else, and if you choose not to use one of the provided
22 <glossterm linkend="gt-session-template">session templates</glossterm>
23 , you will also have to create
24 <glossterm linkend="gt-track">tracks</glossterm> and
25 <glossterm linkend="gt-bus">busses</glossterm> in order to record
26 and/or edit existing audio material.
30 <section id="where-do-plugins-and-sends-go">
31 <title>Where do plugins and sends go?</title>
33 Ardour doesn't have any fixed number of "slots" for
34 <glossterm linkend="gt-plugin">plugins</glossterm>, or
35 <glossterm linkend="gt-send">sends</glossterm>, or
36 <glossterm linkend="gt-insert">inserts</glossterm> : you can have as
37 many per-track as your system has the horsepower handle. The two black
38 boxes above and below the mixer strip's gain fader are
39 <glossterm linkend="gt-redirect">redirect</glossterm> lists where you
40 can add, reorder, remove and generally control plugins, sends, and
41 inserts, both pre- and post-fader.
45 <section id="no-builtin-eq">
46 <title>No builtin EQ</title>
48 Most people don't think much of the EQ's built into other DAWs.
49 Moreover, you cannot meaningfully do equalization with 3 knobs marked
50 "Lo", "Mid" and "Hi". Since good-quality EQ plugins are available for
51 no-cost on Linux, Ardour prefers to allow you to choose one which you
52 prefer. Of course, you can save your session configurations as
53 templates, so if you have a particular EQ that you prefer, you only
58 <section id="no-visible-send-controls">
59 <title>No visible send controls</title>
61 Although Ardour supports sends, there is no way to control them
62 directly from the mixer interface - you don't get a dedicated knob on
63 the mixer strip. However, if you bring up the send's own editor (for
64 example, by double-clicking on its name in the redirect list), you
65 will find a richer set of functionality than most other DAWs offer for
66 controlling the behaviour of a send.
70 <section id="a-smaller-set-of-tools">
71 <title>A smaller set of tools</title>
73 Most DAWs have evolved towards providing the so-called "smart tool"
74 which allows you to use the mouse for several different kinds of
75 operations without changing to a different tool. Ardour has taken this
76 approach from the beginning, so that the "Object" tool actually allows
77 you to carry out many different operations depending on how and where
78 the mouse is used. Ardour does not provide a destructive "pencil" tool
79 as some other DAWs do, for some fairly deep technical reasons. Needing
80 to use a "pencil" tool for waveform repair nearly always indicates a
81 problem with the setup of your session and/or recording hardware. The
82 different tools that ardour does offer include the "Object" tool which
83 has many different uses including region trimming/moving/copying,
84 automation editing, and more; a "Range" tool for defining ranges of
85 time; a "TimeFX" tool for timestretching; a "Gain" tool used
86 exclusively for editing region gain envelopes; and a "Zoom" tool to
87 manipulate temporal zoom. Many other operations are accessible via
88 context menus or <link linkend="sn-key-bindings">keyboard

97 <section id="no-restrictions-on-track-io-configuration">
98 <title>No restrictions on track I/O configuration</title>
100 Tracks and busses in ardour do not come in pre-determined
101 configurations. You can create a mono track, and convert it to a
102 stereo track at any time. You can convert it to a track with 3 inputs
103 and 7 outputs if you want, because Ardour also doesn't restrict track
104 I/O configurations to a fixed set of mono/stereo/5.1/7.1 etc. In
105 addition, because of Ardour's use of
106 <link linkend="sn-configuring-jack">JACK</link> , a track with one
107 input can actually receive data from many different locations. You can
108 also connect any track to any number of other tracks and busses. In
109 Ardour, the only difference between a track and a bus is that a track
110 plays back pre-recorded material from your disk drives and can record
111 to them. Both tracks and busses can have plugins, sends, inserts,
112 automation data and more.
116 <section id="your-audio-hardware-is-not-the-only-io-option">
117 <title>Your audio hardware is not the only I/O option</title>
119 Because Ardour uses <glossterm linkend="gt-jack">JACK</glossterm> ,
120 your session isn't limited to receiving and sending audio to and from
121 your audio interface. It can freely send and receive audio signals to
122 any other JACK application, in some cases even JACK applications
123 running on other computers. On the one hand, this makes understanding
124 the I/O options for a track or bus a little more complex than in a
125 conventional program, but it also adds incredible power to Ardour, as
