For example, I want to put Mid to High (say 3KHz - 20KHz) frequencies through the front channel (configured at green port), and Low to Mid (say 150Hz - 3KHz) frequencies through the rear channel (configured at blue port). The audio as such is not multi-channel, it would be regular stereo audio, only want to divide the frequencies and play them through two different audio-out ports.
You can use the realtime crossover - xDSP (can be downloaded from ).Freeware version can record sound from a loopback sound input or 3-rd party virtual audio driver, process it and route to the analog or s/pdif soundcard output.
Crossover design software solutions are specialized tools that can help audio engineers (or sound aficionados, for that matter) simulate overall speaker SPL (Sound Pressure Level) responses, which perform a check to see if the targets of said design have been met or not.
The crossover capabilities of LspCAD (which spark our curiosity the most) are based on a drag-and-drop principle, which means that working with this tool can be as simple as picking components from a virtual tray and place them on a schematic so that creating a crossover design can be accomplished in a couple of minutes.
Pulseaudio Crossover Rack is a program to design and implement multi-way speaker crossovers using any linux powered computer with a multi-channel sound card and a running desktop environment which uses Pulseaudio as it's sound backend. It also uses a set of LADSPA plugins, namely ladspa-t5-plugins for the heavy lifting of DSP/autio processing. It's written in python3 and uses QT as the windowing toolkit.
The easiest way to install pulseaudio-crossover-rack if you're on an ubuntu based system (Linux Mint for example) is to use my debian repository. Please follow the instructions to set up the apt sources files there...
Generally speaking crossover design software combines loudspeaker SPL responses (that we have previously measured) with filter circuit data (also defined by us, the designers). This allows for the prediction (simulation) of overall speaker SPL responses which -in turn- verify whether design targets have been achieved or not.
Most crossover network software include an automatic optimization procedure which delivers the 'best' set of component values for a given set of design targets and circuit topology. In that sense no differences are expected to exist between different software implementations. However this optimization process may easily fail either if our design targets are impossible to fulfil or our circuit topology is too simple to realize them. In most cases we have to change our circuitry by adding extra components. This usually helps the optimization procedure find the proper components' 'solution'. Therefore successful crossover design often depends on human factor only. A detailed discussion of this issue is given in one of our tutorial articles on crossover design.
Most woofers with low-to-medium sized diameters, exhibit a significant SPL step in the 100-500Hz frequency range due to baffle diffraction. Passive crossover filters can not 'adjust' the woofer's SPL response below 200-300 Hz. What they can do is to manipulate its mid-frequency range above 200-300Hz. A speaker to sound well must have a sort of balance between its 100Hz and 400Hz sound pressure levels. If the sound pressure dB level at 400Hz is 5 or 6 dB above the sound pressure level at 100Hz the speaker will sound 'empty'; music 'body' will be absent. So what crossover filters are expected to do is to suppress the sound pressure level above 400Hz so that it maintains a relatively small (or none at all) difference with respect to the 100Hz level.
For this task a designer must have an accurate woofer SPL response illustrating the baffle diffraction step in order to import it into the crossover design software. As we have already explained in the tutorials' section, reflections in our lab environment make SPL response measurement inaccurate below approximately 300Hz-400Hz. Typical measurement software removes SPL response values below this limit. As a consequence crossover design becomes 'blind' at very low frequencies and our speaker's sound balance gets compromised. Only sound engineers have access to large spaces (or anechoic chambers) for measuring purposes.
From a DIYer point of view crossover design software should be combined to a 'Baffle Diffraction Step' module. Capable of accepting enclosure data and woofer parameters, this module would simulate (predict) the missing low frequency SPL response up to 500-600Hz.
The filter pair can be used for targets in multi-way designs, providing more crossover options. Works for Bessel, Butterworth, Chebyshev I & II & Elliptic filter prototypes. (FIR Designer also has a variety of linear-phase brick-wall crossover filters.)
Linkwitz Riley is just a fancy way of saying that your 2 response curves sum-up flat and the crossover point is -6 dB below linear response. When you are using crossover design software you care less about the topology and focus on the actual frequency/phase response.
what if i would combine 3 speaker drivers having different impedance.woofer(40hms),mid(8 ohms) and tweeter 8(ohms) What would be the impedance that my amplifier may see after the crossover.thanks
Hi? Hoping you are all well. I have designed a 3 way crossover with 2 woofers, mid and one tweeter. I have noticed the impedance curve goes soo low (0.81ohms at 1.18Khz) How can I increase this value? Or will an amp able to handle such a low figure (Denon X4500h)

Do you like buying Windows® licenses? You do? Great. You do you. For the rest of humanity, CrossOver is the easiest way to run many Microsoft applications on your Mac without a clunky Windows emulator. (Seriously, have you tried emulators? Do you like how they run on your Mac?) CrossOver works differently. It's not an emulator. It does the work of translating Windows commands into Mac commands so that you can run Windows software as if it were designed native to Mac.

You want to run full featured Windows software. Impossible they said! Hold our beer. Introducing CrossOver ChromeOS! Run Windows programs that are not available in the Google Play store alongside mobile apps. Scrap remote sessions with multiple users. Run utility software like Quicken and Microsoft Office, or DirectX games, like Wizard101. And bonus: Games from your Steam library will run with CrossOver ChromeOS at native speeds. Roger that!
Audio crossovers are a type of electronic filter circuitry that splits an audio signal into two or more frequency ranges, so that the signals can be sent to loudspeaker drivers that are designed to operate within different frequency ranges. The crossover filters can be either active or passive. They are often described as two-way or three-way, which indicate, respectively, that the crossover splits a given signal into two frequency ranges or three frequency ranges. Crossovers are used in loudspeaker cabinets, power amplifiers in consumer electronics (hi-fi, home cinema sound and car audio) and pro audio and musical instrument amplifier products. For the latter two markets, crossovers are used in bass amplifiers, keyboard amplifiers, bass and keyboard speaker enclosures and sound reinforcement system equipment (PA speakers, monitor speakers, subwoofer systems, etc.).
Crossovers are used because most individual loudspeaker drivers are incapable of covering the entire audio spectrum from low frequencies to high frequencies with acceptable relative volume and absence of distortion. Most hi-fi speaker systems and sound reinforcement system speaker cabinets use a combination of multiple loudspeaker drivers, each catering to a different frequency band. A standard simple example is in hi-fi and PA system cabinets that contain a woofer for low and mid frequencies and a tweeter for high frequencies. Since a sound signal source, be it recorded music from a CD player or a live band's mix from an audio console, has all of the low, mid and high frequencies combined, a crossover circuit is used to split the audio signal into separate frequency bands that can be separately routed to loudspeakers, tweeters or horns optimized for those frequency bands.
Passive crossovers are probably the most common type of audio crossover. They use a network of passive electrical components (e.g., capacitors, inductors and resistors) to split up an amplified signal coming from one power amplifier so that it can be sent to two or more loudspeaker drivers (e.g., a woofer and a very low frequency subwoofer, or a woofer and a tweeter, or a woofer-midrange-tweeter combination). 2b1af7f3a8
