They are very linear when biased by the Common Mode voltages present in most SigmaDSP audio paths and their low ESR (Equivalent Series Resistance) makes them attractive as an 'invisible' component when designing a circuit. Each has strengths and weaknesses.Įlectrolytic capacitors are generally the best performing for this purpose. Besides allowing you to control level, panning, etc., from a single point, you can insert a single plugin into the aux track to process all the tracks collectively, rather than burning up precious CPU by having individual instances of the same plugin on multiple tracks.In general, there are 3 types of capacitors that will be available in the values that are appropriate as AC coupling in most signal paths: electrolytic, tantalum and ceramic. For example, if you have two or more tracks that you want to control collectively, you can create an aux track and route all of their outputs to it (Ex. ![]() The signal may also be routed to various destinations via buses.īuses are simply signal paths from one place to another. In addition to routing a channel’s output signal to the master fader, it may be routed to any available outputs, including directly to the main stereo outputs, bypassing the master fader. Plugins may also be inserted into the master fader channel, in which case they affect the entire mix. Equalizers, compressors and modulation effects, for example, are typically inserted (Ex. Sometimes, rather than splitting the signal into main and auxiliary paths, you want to insert a plugin directly into the track’s main signal path, and that’s exactly what inserts do. The pre-fader/post-fader option provides lots of useful flexibility that I won’t go into here. There’s also a pre button that determines whether the signal is sent before or after the track’s channel fader. Like track channels, aux sends have level faders, pan controls, and mute and solo buttons (Ex. That way, reverb is added to the sound of the track, but the signal doesn’t run through the reverb plugin. The recorded audio is still being routed directly to the master fader, but it is simultaneously being routed to the reverb using a second signal path. Aux sends are used for many different purposes, like routing the signal to an effects plugin, such as a reverb that has its own aux track.

But despite these many advancements, it’s very easy to wind up with a disjointed or sterile product. With advancements in recording technology, and the dropping cost of entry, it has never been easier to bring your musical vision to life. 2).įour Ways to Keep Your Home Mixes Cohesive You can also stop the sound dead in its tracks using the mute button, or mute all of the other tracks and hear it alone using the solo button (Ex. 1).Įn route to the master fader, the signal passes through a pan control, which allows you to adjust the amount of signal being sent to the left and right channels of the stereo mix, determining where the sound is positioned within the 180-degree stereo image. That’s the most direct signal path from the recorded track to the monitors when using a master fader (Ex. The default output selection on a track’s mixer channel routes the audio to the master fader, via output 1-2, and from there it goes back into the audio interface, where it is converted to analog and sent to the powered speaker system.
