|

1. Download the Equalizer APO Setup for your version of Windows (32 or 64 bit). If you are unsure if you need the 32 or the 64 bit version, you can open Start Menu -> Control Panel -> System and look up the system type.

1. Download the Equalizer APO setup for your version of Windows (32 or 64 bit). If you are unsure if you need the 32 or the 64 bit version, you can open Start Menu -> Control Panel -> System and look up the system type.
|
||||
2. Execute the setup program and follow the instructions. Remember your installation path if you don't use the default of C:\\Program Files\\EqualizerAPO . From here on, for better readability it is assumed that you use the default path.
|
||||
3. During the installation process the program Configurator.exe will be run. Make sure that you select the correct audio device to install the APO to. If you are unsure you can open Start Menu -> Control Panel -> Sound and look for the default output device. If you need to install the APO to other audio devices later, you can run the program again from C:\\Program Files\\EqualizerAPO\\Configurator.exe .
|
||||
4. After the installation finished, you should allow the reboot of your system. This is needed because the newly installed APO will not be used immediately but only after the audio service is restarted.

A detailed explanation of the usage of Room EQ Wizard is out of the scope of this document, but here is the basic process:
|
||||
|
||||
1. Click the "Measure" button in the toolbar (Mark A in the above screenshot) to bring up the measurement dialog. Here you should first do "Check Levels" and adjust your output volume appropriately, then "Start Measuring". After the measurement, the dialog will close automatically and a frequency response graph is shown.
|
||||
2. Click the "EQ" button (Mark B) in the toolbar. Here you can select an equalizer type (Mark C). Use either "Generic" or, if you prefer bandwidth instead of Q, the "FBQ2496" equalizer type. Beware that no other equalizer types are currently supported.
|
||||
3. Click the "EQ Filters" button (Mark D) in the EQ window. Now you can add filters by setting "Control" to Manual, "Type" to PK/PEQ and then adjusting "Frequency", "Gain" and "Q"/"Bw Oct" to your needs. The graph in the EQ window will directly show the filter's frequency response.
|
||||
3. Click the "EQ Filters" button (Mark D) in the EQ window. Now you can add filters by setting "Control" to Manual, "Type" to PK/PEQ and then adjusting "Frequency", "Gain" and "Q"/"Bw Oct" to your needs. The graph in the EQ window will directly show the filter's frequency response. Since version 0.8, you can also use any of the other filter types available if they suit your needs, but generally the peaking filters should be the most appropriate for room correction.
|
||||
4. To save the filter settings, you should first use the "Save this filter set" button (Mark E) in the EQ Filters window. This will save the settings in a format that Room EQ Wizard can read back later when you need to make further adjustments.
|
||||
5. Now save the filter settings in a format that Equalizer APO can read. To do this, go to the main window of Room EQ Wizard. Open the "File" menu (Mark F) and select "Export" -> "Filter Settings as text". Save under a new filename into C:\\Program Files\\EqualizerAPO\\config .
|
||||
6. Open C:\\Program Files\\EqualizerAPO\\config\\config.txt in a text editor and change the "Include" line to refer to your newly created configuration file. The change should be effective immediately.

Congratulations, you have now created your first configuration for Equalizer APO. To learn more about the usage of RoomEQWizard, you can look into its [help file](http://www.hometheatershack.com/roomeq/wizardhelpv5/help_en-GB/html/index.html).

The commands currently defined are:
|
||||
|
||||
Command | Parameters | Description
|
||||
-|-|-
|
||||
Preamp | ***Negative number*** db | Sets a preamplification value in decibels. This is useful when you are using filters with positive gain, to make sure that no clipping occurs.
|
||||
Preamp | ***Negative number*** dB | Sets a preamplification value in decibels. This is useful when you are using filters with positive gain, to make sure that no clipping occurs. Since version 0.8, when multiple preamps apply to the same channel, the resulting preamp is the sum in dB.
|
||||
Include | ***File name*** | Loads the given file as a configuration file. Instead of directly replacing config.txt, it can be better to load the actual filter definition from a separate file so that you can e.g. set a preamp before.
|
||||
Filter ***n*** | ON PK Fc ***Frequency*** Hz Gain ***Gain value*** dB Q ***Q value*** | Adds a parametric equalization filter with the given frequency, gain and Q. This is the filter text format used by Room EQ Wizard for equalizer type "Generic".
|
||||
Filter ***n*** | ON PEQ Fc ***Frequency*** Hz Gain ***Gain value*** dB BW Oct ***Bandwidth value*** | Adds a parametric equalization filter with the given frequency, gain and bandwidth. This is the filter text format used by Room EQ Wizard for equalizer type "FBQ2496".
|
||||
Filter ***n*** | ON ***Type*** Fc ***Frequency*** Hz Gain ***Gain value*** dB Q ***Q value*** | Adds a filter of the given type with the given frequency, gain and Q. The supported filter types and their parameters are listed <a href="filter_types">below</a>. This is the filter text format used by Room EQ Wizard for equalizer type "Generic".
|
||||
Filter ***n*** | ON ***Type*** Fc ***Frequency*** Hz Gain ***Gain value*** dB BW Oct ***Bandwidth value*** | Adds a filter of the given type with the given frequency, gain and bandwidth. The supported filter types and their parameters are listed <a href="filter_types">below</a>. This is the filter text format used by Room EQ Wizard for equalizer type "FBQ2496".
|
||||
Device | ***Device identification pattern*** | Matches the given pattern to the connection name, device name and GUID of the current output device. If the pattern does not match, all following commands except Device commands are ignored. The pattern consists of words separated by space that must all be found in the string "***Device_name*** ***Connection_name*** ***GUID***". Multiple patterns of which one must match can be specified by separating the patterns with ';'. The special pattern "all" matches always. The benchmark application uses the device name "Benchmark" and connection name "File output". The easiest way to generate a Device command is to use the button in the Configurator application. (added in version 0.7)
|
||||
Channel | *** Channel positions *** | Selects the channels to which the following Filter and Preamp commands will be applied. Channel positions can be given by identifier (acronym of 1 up to 3 characters) or by number (counted from 1). The supported channel configurations are listed <a href="channel_configs">below</a>. If a channel configuration is not supported, channels can only be selected by number. Multiple channels can be specified by separating with space. The special position "all" selects all channels.

# Filter types
|
||||
|
||||
The following table lists the filter types supported by Equalizer APO since version 0.8. The columns Fc, Gain and Q/BW show the parameters supported by the filter type. An 'X' means that the parameter is required while an 'O' denotes an optional parameter. The filter types supported cover all filters of the "Generic" and the "FBQ2496" equalizer type. Other equalizer types may also be compatible if their filter text format is. There is one exception however: The band-pass filter supported by Equalizer APO is a real band-pass filter that does not support gain, like low/high-pass filters, but unlike the DCX2496's "BP" filter, which is actually a peaking filter.

# Channel configurations
|
||||
|
||||
The following table lists the channel configurations that are supported by Equalizer APO. The channel identifiers in the column titles resemble the channels in Start -> Control Panel -> Sound -> Configure. If a channel position is supported for a configuration, the cell in the corresponding row contains the channel number.

<b>Attention:</b><br>
|
||||
|
||||
Although it might be tempting to assign low frequency filters only to the subwoofer channel, this might not lead to the expected results. Many audio systems apply bass redirection after Equalizer APO has processed the signal, so filters applied to the subwoofer channel won't be effective for redirected sound. Furthermore, as crossover filters only gradually fade in, the low frequency audio might be played over multiple speakers, not just the subwoofer, reducing the effectivity of subwoofer-only filters. Therefore, to avoid these problems, it's recommended to <b>apply low frequency filters to all channels</b>.
