EffectDeck

Getting the latest details from the App Store…
EffectDeck puts an effect chain on the audio other apps are already playing, and the effects you can put in it are not limited to the ones it ships with. Pick EffectDeck as the output in Control Center, then open the app and build a chain. No virtual cable, no routing to set up, nothing to configure first. Start from over 100 of EffeTune's effects, running unmodified: the same DSP code EffeTune runs on the desktop and on the web. Add the AUv3 plug-ins already on your device and your own…

Restart your iPhone or iPad once after this update (the device, not the app). Until you do, EffectDeck shows up in Control Center but won't connect, and the main screen shows Restart Required. Only this update requires it. A fresh install does not. New since 2026.10.04 New - Output Correction: assign one of your presets to each pair of headphones or speaker. It is applied after the chain, switches automatically when the output changes, and never modifies the chain. Choose it from the Output Correction row below the chain. Fixes - Third-party AUv3 plug-ins did not appear under Plugins. - Apple Audio Units such as AUDelay showed only parameter controls instead of their own interface (since 2026.09.28). - Dropping below the last card failed after Reset chain or deleting a card. Other - JSFX scripts run about 1.3 to 1.4 times faster on iPhone, with bit-identical output. - JSFX: fixed a crash or incorrect values when a function using x[] was called more than once, and a crash from file_rewind or file_riff on a handle that is not open. - Available Effects has three tabs: Effects, Plugins and Presets. Import JSFX is at the top of Plugins, and System Presets are at the end of Presets. - Effects can be dropped beside and between cards, below the last card, onto an empty chain, and, on iPad, onto the left list. Previous updates (2026.10.04): EffeTune 2.12.0 (DSP 0.12.0) - New: Analog Meter, Rhythm Analyzer and Tonal Balance EQ. - Note Spectrogram adds keyboard and Volume controls matching EffeTune. - Effect resets and default values match upstream. Pitch Meter adds orientation. - AM Radio, TV Audio and Vinyl controls use tabs matching EffeTune. - IR Reverb adds preprocessing controls, and Room EQ adds its graph. - Connection timeout detection uses data received from the current peer. - JSFX fixes address integer overflow and memory handling. Previous updates (2026.09.28): iPad - A wide window shows the chain as a list on the left and every card open on the right. Reorder in the list, and drop effects into it. JSFX EffectDeck hosts JSFX, the single-file script format REAPER uses. - Import from Files, a link, the clipboard or the share sheet. - Sliders keep their ranges, curves and menus. Scripts that draw (@gfx) get a canvas with touch, keyboard, menus and full screen. - @serialize state is saved with the chain and presets. Reported latency is compensated. - A script that keeps overrunning its time budget is bypassed, and the card says by how much. Re-enable puts it back. - In Plugins, the ... next to a script offers View Source, Copy Source, Share as a link and Delete. EffeTune 2.11.0 (DSP 0.11.0) - New: Attack Tonal Balance, Bass Extender, Chroma Spiral, Bass Management. - Oversampling up to 8x on Saturation, Dynamic Saturation, Exciter, Harmonic Distortion and Multiband Saturation, 16x on Hard Clipping. Presets and sharing - Presets > Import from clipboard reads a chain pasted as text. - Share this chain makes an effectdeck.nemut.ai link that opens EffectDeck and keeps AU and JSFX stages. - 15Band PEQ imports an AutoEq ParametricEQ.txt. Known - Older versions of Spotify cannot connect on tracks with Canvas. Update Spotify to the latest version. Spotify or YouTube sometimes cannot connect because iOS treats them as video. See Known limitations and issues #1, #3 and #4. - Overnight battery use is still being measured (issue #5).
