Overview

MADRIX 5 supports audio input as well as audio output.

Audio input is used for a variety of MADRIX Effects and therefore audio-reactive visuals. The software uses incoming audio signals to create lighting effects. These include the S2L, M2L, and MAS Effects.
Audio output is used as audio playback for video files in the SCE Video Effect.

MADRIX can work with an audio signal and it can work without an audio signal. But audio input is highly recommended. S2L and M2L Effects will create unique real-time effects based on sound, which will take your lighting display to the next level.

 

Audio Input Sources

Audio input can come from different sources [internal or external]. It is just a matter of configuration. MADRIX will allow you to set up every device that the Microsoft Windows operating system offers for recording.

Internal sources:

Software MP3 players [including other audio file types or music tracks]
Other music or audio applications
Microphone [e.g., built into notebooks]
Audio-CD
Stereo Mix
Others

External sources:

Line-In
Microphone
SPDIF
Others

 

Audio Output Sources

Audio output can only come from videos played back in the SCE Video Effect. [The MADRIX Software is primarily a lighting control tool without advanced audio functions.]

Audio Input Configuration With WDM

Enable Audio Input

Windows Audio Drivers- Enables the standard Windows audio drivers [Windows Driver Model]. It is activated by default.

Audio Device - Shows all available audio input sources.
- You can properly assign your Stereo Mix, Line In, Microphone, or other specific devices by selecting the device from the drop-down list.
- Stereo Mix is the accumulation of all channels and often is used as default. [This setting is recommended.]
- If you cannot select your preferred audio input device, make sure it is correctly set up in Windows. Learn more Sound Recording Device
 
Use For S2L Effects - Is activated by default. Deactivate this option if incoming audio signals should not be used for MADRIX S2L Effects [not recommended].
Use For M2L Effects - Is activated by default. Deactivate this option if incoming audio signals should not be used for MADRIX M2L Effects [not recommended].

 

Audio Input Configuration With ASIO

ASIO LogoASIO [Audio Stream Input/Output] is a widely known audio standard.
Above all, the standard provides low latency; a feature often requested by professionals. When using ASIO, the MADRIX audio analysis will be faster and more precise. While the WDM drivers often provide 100 FPS, even higher sampling rates are possible with ASIO.  ASIO is a registered trademark of Steinberg Media Technologies GmbH.

 

Before using ASIO with MADRIX, please make sure that the ASIO drivers are installed on your computer. If the drivers are not installed, MADRIX will not be able to find the ASIO audio hardware.
It is recommended to connect external ASIO hardware [a USB sound card, for example] directly to a USB controller of your PC. It is not recommended to use a USB hub or the front-USB of your computer.
Use USB 2.0.

 

Enable Audio Input

Windows Audio Drivers- Enables the ASIO audio drivers.

ASIO Configuration

Configure the following settings:

Audio Device - Select your interface or sound card in this drop-down list.
Left Channel - Select the appropriate device for the left audio channel.
- If you are seeing the message No input channel was found! [like shown in the screenshot above], please connect your ASIO device.
Right Channel - Select the appropriate device for the right audio channel.
- If you are seeing the message No input channel was found! [like shown in the screenshot above], please connect your ASIO device.
 
Use For S2L Effects - Is activated by default. Deactivate this option if incoming audio signals should not be used for MADRIX S2L Effects [not recommended].
Use For M2L Effects - Is activated by default. Deactivate this option if incoming audio signals should not be used for MADRIX M2L Effects [not recommended].

 

ASIO Device ConfigurationWill let you configure your ASIO device further if advanced settings are available. Usually, the ASIO drivers that come with your interface will be launched. Make sure that your ASIO hardware is connected. Or else, no configuration window may be launched.

In this configuration window you can set various settings. The music analysis will be more precise if the latency / amount of samples is as low as possible. Often, this setting is called 'Buffersize'. You can achieve milliseconds with ASIO. 1000 frames represent 1 ms. 500 frames represent 2 ms. 250 frames represent 4 ms, and so on. You will be able to see the number of frames that is captured in the Task Watcher.
Click Apply to save the settings.

 

Audio Output Configuration

Enable Audio Output

 

MADRIX will automatically use the sound playback device configured in the Windows operating system.

Audio Performance

The results of the audio analysis are mainly influenced by the following factors:

Computer speed.
Level of the audio signal.
Audio Performance settings.

 

You are able to adjust Audio Performance settings, which are the parameters for the audio analysis.

Go to the menu Preferences > Audio Performance...
[Keyboard shortcut: Ctrl+Alt+A]
A new window will open.

Audio Performance Dialog
 

S2L M2L Performance - Defines how much data is available for the audio analysis. The default value is 3.
- The higher the value, the more data is available and the more precisely especially M2L Effects can be. That also means that the delay increases [in ms]. If the value is too high, it can affect the performance of MADRIX/of the computer.
M2L Cleaner - Works only for M2L Effects and harmonic frequencies. It cleans the incoming audio signal for resonances and secondary frequencies to filter out unwanted tones.
- The higher the value, the more likely a note/tone has in fact occurred in the music. But the higher the value, the more notes will be filtered out as well.
M2L Threshold - Works only for M2L Effects and defines a threshold value.
- The higher the value, the more likely a certain note/tone has in fact occurred in the music.
- The lower the value, the more notes will be used for M2L Effects.
- Setting up a very low M2L Sensibility value [such as 0] can require a lot of computer performance and might negatively affect the display of S2L Effects and M2L Effects. Increase the value again if you are experiencing any issues.
 
Defaults - Restores the default settings.
 
OK - Applies any changes and closes the window.
Apply - Applies any changes without closing the window. [In this way, this allows you to quickly test different settings. Change the settings, click Apply, and observe the results for S2L and M2L Effects.]
Cancel - Disregards any changes and closes the window.

 

Different styles of music may require different Audio Performance settings for an optimal display.

 

Volume

The volume or audio input level as well as audio output level can be controlled on the user interface.

Troubleshooting

If you are having problems with the audio configuration, try the following:

Select Preferences > Device Manager... > Audio > Defaults to restore the default settings. Alternatively, select the correct audio device [e.g., Stereo Mix].
Then, click Apply. Click OK to close the window.
Check the Windows audio settings and see if your recording or playback devices are configured correctly.
Check that the Windows Volume Mixer has the right sound levels and is not set to 0.
Check the installation of the [latest] drivers of your sound card.
Check the installation of Microsoft DirectX®.
Test with a different sound card.
If you are encountering problems with ASIO [when effects freeze or single frequencies overmodulate], change the latency settings. A higher latency and thus lower capture frame rates can solve the problem.
