# DeckSP

DeckSP is a DSP plugin for Steam Deck. It provides a suite of audio effects that are easily manageable in game mode. The plugin is built on top of [JamesDSP for Linux](https://github.com/Audio4Linux/JDSP4Linux)*, offering access to most of its effects and features, along with some additional features specifically for the Steam Deck.

*DeckSP uses the flatpak version of JamesDSP. Installation/ uninstallation is automatically handled by the plugin.

## Features

### Effects

- **Limiter**

- **Equalizer** 15 band EQ

- **Dynamic Range Compander** (Compressor/ Expander)

- **Stereo**

  - Wideness

  - Crossfeed

- **Reverb**

- **Dynamic Bass** (Frequency-detecting bass-boost)

- **Tube Modeling** (Analog harmonics modeling)

### Profiles

Individual profiles that encompass the settings for all effects.

- **Automatic Profiles**: DeckSP can automatically apply audio profiles on a per game basis.

- **Manual Profiles**: You can also manually create and apply custom profiles.

## Installation

To install DeckSP, follow these steps:

1. Install [Decky Loader](https://wiki.deckbrew.xyz/en/user-guide/install) ([Info](https://wiki.deckbrew.xyz/en/user-guide/home) / [Github](https://github.com/SteamDeckHomebrew/decky-loader)) on your Steam Deck.

2. Download and install the DeckSP plugin from the [Decky Plugin Store](https://wiki.deckbrew.xyz/en/user-guide/plugin-store).

## Usage

To use DeckSP, navigate to the plugin in Decky through the Quick Access Menu.

The plugin is organized into multiple pages:

- **Main Page**: Manage profiles.

  - When running a game, toggle "Use per-game profile" to create a new profile for the current game, which will be automatically applied whenever the game is running.

  - Use "Manually apply profile" to apply a specific profile (either auto-generated or custom-named), overriding the per-game profile option.  

    When enabled, an index finger icon will appear next to the profile to indicate that it is manually applied.

- **Effect Pages**: Each page is dedicated to a specific effect or group of similar effects.

  - Adjust effect parameters as desired.

  - Each effect can be toggled on/off individually.

  

  All changes affect the currently applied profile.

## Credits

DeckSP relies on [JamesDSP for Linux](https://github.com/Audio4Linux/JDSP4Linux), developed by Tim Schneeberger ([@thepbone](https://github.com/thepbone)), as the backend for audio processing. JamesDSP for Linux is based on the original [JamesDSP](https://github.com/james34602/JamesDSPManager) project for Android, initially published by James Fung ([@james34602](https://github.com/james34602)).

Special thanks to the developers of both projects for their excellent work.
