The Output Format DSP is the most important DSP included. It allows Media Center to automatically handle a variety of output formats automatically, even if they aren't compatible with your installed hardware.

The Output Format DSP provides:

* '''Output Encoding:''' This allows you to select specialty output encodings for use with an external DAC, signal processor, or Home Theater Receiver. If selected, all audio output will be re-encoded to this format before being sent to the audio device. This is rarely needed, and is only recommended if your audio device can ''only'' play a particular format successfully (such as playing multichannel audio over SPDIF or when using a DAC that ''only'' works with [[DSD]] formats).


This allows you to select output encodings for use with an external DAC, signal processor, or Home Theater Receiver. If a value other than None is selected, all audio output will be re-encoded to the specified format before being sent to the audio device.
* '''Sample Rate:''' This provides access to Media Centers high-quality resampler. This system allows you to pass through untouched (via the No Change setting) all formats that your audio hardware can handle natively, while automatically handling file formats for which playback would otherwise fail.


The formats available (in MC23) are;
* '''Channels:''' This allows you to handle multi-channel audio files properly. It will allow you to upmix or downmix audio playback via a variety of high-quality methods, which will allow you to play back multichannel recordings even on a two-channel audio device, and provides Media Center's superb JRSS upmixer which can (if desired) upmix stereo sources to surround sound (similar to Dolby ProLogic or DTS Neo Pro).


* Dolby Digital
* '''Subwoofer:''' If you have a sub attached to your system, you can set crossover frequencies here, and enable Media Center's Subclarity feature.
* DSD in DoP format (at 1x, 2x and 4x)
* DSD in native format (at 1x, 2x, 4x and 8x) (requires ASIO)

These options are only recommended if your audio device can ''only'' play a particular format. For example, playing multichannel audio over SPDIF or when using a DAC that ''only'' accepts with [[DSD]].

=== Sample Rate ===

This allows you to select an output sample rate per input sample rate. If "no change" is selected, the signal is passed through without resampling.

The resampler used is either the internal MC resampler or SoX if the "Use SoX for resampling" option is selected for this zone in ''Options > Audio''

This dropdown controls

* how many channels will be sent to the output device

Your output device '''must''' support the specified number of channels or playback '''will fail'''.

The options range from mono up to 32 discrete channels.

There are a number of options described as "x channels (inside y channel container)". In these cases "x channels" refers to the mix target and "y channel container" refers to the number of channels sent to the output device.

==== Mixing ====

This option controls whether, and how, the source content is remixed to fit into the selected number of output channels.

The recommended option is to use JRSS mixing.

For example, it can upmix stereo to multichannel surround or downmix surround to stereo.

Output Format is used to control

  • how many channels are in the output format
  • how the source content is mixed to that target format (if at all)
Media Center's Output Format DSP.

Output Encoding

This allows you to select output encodings for use with an external DAC, signal processor, or Home Theater Receiver. If a value other than None is selected, all audio output will be re-encoded to the specified format before being sent to the audio device.

The formats available (in MC23) are;

  • Dolby Digital
  • DSD in DoP format (at 1x, 2x and 4x)
  • DSD in native format (at 1x, 2x, 4x and 8x) (requires ASIO)

These options are only recommended if your audio device can only play a particular format. For example, playing multichannel audio over SPDIF or when using a DAC that only accepts with DSD.

Sample Rate

This allows you to select an output sample rate per input sample rate. If "no change" is selected, the signal is passed through without resampling.

The resampler used is either the internal MC resampler or SoX if the "Use SoX for resampling" option is selected for this zone in Options > Audio

Channels

There are a number of options in this section, all of which control exactly how many channels are sent to the output device and how the source content is mixed to those channels.

Output Channels

This dropdown controls

  • how many channels will be available to all subsequent DSP blocks
  • how many channels will be sent to the output device

Your output device must support the specified number of channels or playback will fail.

The options range from mono up to 32 discrete channels.

There are a number of options described as "x channels (inside y channel container)". In these cases "x channels" refers to the mix target and "y channel container" refers to the number of channels sent to the output device.

Mixing

This option controls whether, and how, the source content is remixed to fit into the selected number of output channels.

The recommended option is to use JRSS mixing. JRSS is Media Center's built in remixer which performs a similar job to remixers such as Dolby ProLogic or DTS Neo 6. For example, it can upmix stereo to multichannel surround or downmix surround to stereo.

Subwoofer

If you have a sub attached to your system, you can set crossover frequencies here, and enable Media Center's Subclarity feature.
