The peak meter monitors the signal selected by the <emphasis>Pre/Post/Input - Button</emphasis> .. the same signal as the meters. It should be noted here - that 0dBfs corresponds a value equal to the maximum input or output level - of your audio hardware, independent of it's bit depth. - </para> - </section> - - <section id="mixer-strip-gain-fader"> - <title>Gain Fader</title> - <para> - The fader changes the signal level within the mixer strip before the - post-fader plugins, which are before the output ports. 6dB of gain is - allowed. there are several shortcuts available for the fader. Using the - scroll wheel of your mouse while hovering above the fader will coarsely - change its position. Holding the control key whilst mouse wheeling will - give you finer control. Holding the shift key and clicking the fader will - reset it to unity gain. Holding control and pressing the middle mouse - button whilst over the fader will allow you to bind a midi control to it, - provided you have an available midi device set in the options menu. - </para> - </section> - - <section id="mixer-strip-meters"> - <title>Meters</title> - <para> - The number of meters displayed next to the fader is dependent on the number - of inputs or outputs the channel has, whichever is greater. The meters - provide a colour-graduated scale from -50 dBfs to +6dBfs. They display the - instantaneous value of the signal at the monitoring point selected by the - Pre/Post/Input button. 0dBfs corresponds a value equal to the maximum input - or output level of your audio hardware, independent of it's bit depth. - Exceeding 0dBfs does not correspond to running out of headroom within the - mixer, or in any signal path subsequent to that point within the Jack - server. It merely means that if that signal is connected directly to a - hardware port whose resolution is less than the 32-bit floating point - resolution that Ardour uses (i.e. a soundcard), then that port will exceed - it's maximum output level, resulting in distortion. hitting 0dB within the - mixer (or any point in the Jack server) means that you have approximately - 100dB of headroom remaining. as it is unlikely that you will reach this - point, it is not represented in any special way by the meter. Naturally, if - the input is selected as the monitoring point for the meter, exceeding - 0dBfs means that the input of your a/d converter has clipped. - </para> - </section> - - <section id="mixer-strip-panner"> - <title>Panner</title> - <para> - The panner in Ardour is actually two panners. Because any mixer strip in - Ardour can route any number of streams of audio anywhere, the idea of - panning can be a complex one. To allow for the current stereo-centric - mainstream world as well as the multi-speaker experimental one, one of two - styles of panner will appear here depending on the number of outputs the - channel strip has. In the simple case of mono channel input / stereo - output, a single panner will be present. The current pan position is - represented by a dot (the dot is the audio stream) which lies between the - letters 'L' and 'R', which represent the left and right outputs - respectively. To change the panning position of the stream, move the mouse - while holding down the left mouse button. the dot will follow your mouse - pointer. To introduce sudden changes to the pan setting, place the mouse - pointer over the desired position and click the middle mouse button. The - pan control will immediately snap to the mouse pointer position. The panner - may be bypassed by right-clicking the control and selecting - <guimenuitem>bypass</guimenuitem> from the drop-down menu. The panner will - immediately be bypassed. The increased level you notice when the panner is - bypassed is due to the way panning works. It is not a bug. <emphasis>XXX - what gain law is used in the panner?</emphasis> - </para> - - <para> - In the case of a stereo input / stereo output combination, two panning - controls will appear, one corresponding to each audio stream. You can - <emphasis>link</emphasis> the controls together in two different ways in - this situation, using the direction arrows next to the - <guibutton>link</guibutton> button. Panners can be linked to travel either - in opposite directions or to maintain a consistent stereo width across the - travel of the control. These two modes are represented by the orientation - of the two arrows next to the <guibutton>link</guibutton> button, which - point in either the same or opposite directions. The - <guibutton>link</guibutton> button must be engaged before you can change - the <emphasis>link</emphasis> mode. To link all the panners in a mixer - strip, left-click the <guibutton>link</guibutton> button, then select the - desired link mode by pressing the button marked with arrows. - </para> - - <para> - Let's get a little more complicated by adding another output to the mixer - strip. From this point onwards, the panning positions are represented with - numbered dots on a square field. Orange dots represent the outputs, and the - numbered dots represent the streams. the position of the outputs change - according to the number of outputs in the strip. This happens in order to - allow the most useful arrangement of the available space. At some point, - adding an output will cause the outputs to line up from the top left of the - panning square towards the centre. this is to allow for the 'multi-speaker - big sweep' to occur - where the sound is panned from speaker to speaker - around the room in sequence. - </para> - - <para> - Don't forget that you can bypass the panner by right clicking and selecting - <guimenuitem>bypass</guimenuitem> from the drop-down menu. this may - simplify your multi-speaker setup, as often in this type of project panning - between all speakers or outputs is not required on all tracks. - </para> - </section> - - <section id="mixer-strip-output-selector"> - <title>Output Selector</title> - <para> - The output selector allows you to assign the outputs of each mixer strip. - left-clicking the output selector causes a ready-made list of output ports - to appear in a drop-down menu, along with edit and disconnect options. - Selecting <guimenuitem>Edit</guimenuitem> will allow you to change the - number of outputs the channel has, as well as select software and hardware - ports to route signals to.

Because any mixer strip + in Ardour can route any number of streams of audio anywhere, the idea + of panning can be a complex one. To allow for the current + stereo-centric mainstream world as well as the multi-speaker + experimental one, one of two styles of panner will appear here + depending on the number of outputs the channel strip has. In the + simple case of mono channel input / stereo output, a single panner + will be present.
