	AudioDSP (Audio Digital Signal Processing) add-ons allow for enhanced audio processing in Kodi. It is a technique to transform or modify signals using computers. It relies heavily on mathematics and computer science. It is used in wireless communication and all sorts of scenarios which use audio signals. A common use is to to boost or cut the low frequency range of a subwoofer which may be connected to an AV-Receiver. Currently these techniques are outside of the Kodi core program.

			It started as the first add-on for AudioDSP. It's usecase is to provide basic and usefull tasks for audio processing.

			Available modes:
			* Speaker Gain. Here you can set gain values for all speaker channels of your configured ActiveAE sink.
			* Speaker Delay. Here you can set delay values for all speaker channels of your configured ActiveAE sink.
			* Dolby Pro Logic II downmixes your audio stream to stereo if your sink is configured with 2.0.

			Available modes:

			* Freesurround upmix is available if you configure your ActiveAE sink through more than 2.0 (stereo).

	: ~~description goes here~~.
			This add-on is based on [//github.com/kodi-adsp/adsp.template adsp.template] and [//github.com/AchimTuran/asplib/ asplib], which implements a [//en.wikipedia.org/wiki/Digital_biquad_filter biquad filter] structure for signal filtering. The filter structure is very familiar in audio processing and allows the realisation of almost all filter types like low-, high-, band-pass ...
			Currently this add-on only has one design equation for an graphical equalizer with 10 frequency bands and a main gain value. It processes all audio channels with the same filter configuration except the LFE (Low Frequency Effects or sub woofer) channel. This channel should be created or processed by another pre-processing add-on when LFE is not available.

			Available modes:

			* Post processing mode for all available audio sink channels except LFE.

	ADSP add-ons are binary [[add-ons]], but in [[Ubuntu]] they are not packaged with Kodi. All other official Kodi versions have these add-ons included with the default install. For Ubuntu, they must be installed through apt-get. In the future this will be something the user can manage from within the Kodi GUI, but for now they must be installed outside of Kodi.
