3 <dfn>Inserts</dfn> are signal tap points that can be placed anywhere
4 inside a channel strip. Unlike Auxes, they will interrupt the signal flow,
5 feeding the signal from before the insert point to its <dfn>Insert
6 send(s)</dfn>, and connecting the remainder of the channel strip to the
7 <dfn>Insert return(s)</dfn>, both of which are either audio device or JACK ports.
11 When an insert is created, the signal will be interrupted until the relevant
12 connections to the insert ports are made!
16 While jack ports are visible to other JACK applications, ALSA ports are only
17 useful for patching in audio equipment external to the computer. If inserting
18 a software processor is required, a plugin would be the first choice. If a plugin
19 is not available then the jackd audio backend would have to be used. This is
20 not very common any more but there are some older jack clients that require
24 Inserts work the same as the inserts on analog consoles except they are not
25 normalled like most jacks on an analog console.
28 An insert allows to either use a special external DSP JACK
29 application that is not available as a plugin, or to splice an external
30 analog piece of gear into a channel strip, such as a vintage
31 compressor, tube equalizer, etc. In the latter case, the inserts would first
32 be connected to a pair of hardware ports, which are in turn connected to the
33 outboard gear. This is done on the <kbd class="tab">Send/Output</kbd> and
34 <kbd class="tab">Return/Input</kbd> tabs of the <kbd class="window">Insert</kbd>

41 Insert Dialog, the Send/Output tab
46 Apart from providing access to the connections matrix, the dialog allows adjusting
47 the output gain and toggling phase inversion for Send/Output, as well as measuring
48 and adjusting latency for the insert.
52 Inserts will incur an additional period of latency, which can be
53 measured and compensated for during mixing, but not during tracking!
57 Disabling (bypassing) an insert is done by clicking on its LED in the processor box.
