DSP

What is DSP Studio?

DSP Studio allows you to apply a variety of powerful and flexible digital signal processors in order to implement features like:

• active crossovers
• room and speaker correction
• equal loudness volume controls

and much much more.

This is achieved via the use of built functionality or via third party VST plugins.

To access DSP Studio, you can either:

• Choose the Player Menu, then DSP Studio; or
• Click the DSP button on the main UI screen; or

• Use the CTRL+D keyboard shortcut

Available DSPs

DSP Studio contains a number of high-quality Digital Signal Processors, much like those that would be included in a high-end AV Receiver (and individual pro components). These include:

• Output Format
• Volume Leveling
• Adaptive Volume
• Equalizer
• Parametric Equalizer
• Effects
• Headphones
• Tempo & Pitch
• Room Correction
• Convolution
• Parametric Equalizer 2

Managing VST Plugins

VST is a standard interface for audio plugins.

Adding a VST

To add a VST:

• Open DSP Studio
• Click Manage Plugins > Add JRiver, VST, Winamp Plug-in...

• Select the VST DLL from your filesystem
• The VST should now appear in the DSP list, in this example we've added Voxengo SPAN

Removing a VST

To remove a VST:

• Open DSP Studio
• Click Manage Plugins > Uninstall
• Select the plugin to remove

VST Versions

Media Center supports VST2 and VST3 Plug-ins. (See VST discussion at https://yabb.jriver.com/interact/index.php/topic,126706.0.html)

Controlling the DSP Processing Chain

Ordering DSPs

The order in which the DSP blocks are processed can be changed by dragging and dropping the relevant block. This enables you to choose in which order certain actions are performed.

The exceptions to this rule are Output Format, Volume Leveling and Adaptive Volume which must be processed first.

Enabling and Disabling Individual Blocks

Each block has a checkbox next to it, if the box is unchecked then the block is ignored.

Additional Options

An options button appears in the top right corner of DSP studio for some blocks. This allows you to set 2 additional options for that block:

• process independently of internal volume: this means the block receives a signal that has not been affected by the volume control
• process only when viewed: typically useful for visualisers to avoid the cpu cost when the block is not visible

Understanding the Playback Chain

Audio Path is always on hand to provide a detailed description of exactly what processing is applied during playback.
