Sliver is a powerful tool for soundscape and sonic texture creation.

Working beautifully with any audio content... melodic, rhythmic, noise, or otherwise, Sliver is well suited for a broad range of project types including:

Sound Design / Sound Effects
Unique Sonic Textures
Cinematic Sound Elements

Creating a playable instrument from any sound.

The core of Sliver is the 4 real-time resizable clips (slivers) that can be moved around the waveform. Each sliver has it’s own channel with independent volume, pan, filter, and sliver size. These controls can be set in motion with Sliver's automation engine. Sliver uses a real-time automation system to movement in your textures. This system also allows for override to be able to shape the ongoing captured performance. The filters and size windows are controlled by XY pads, giving Sliver a natural playability, creating a new type of instrument.

Touching along the waveform places, moves, and sizes the slivers, allowing you to intuitively scrub the waveform with a variable loop size.

A chain of effects assigned to XY Control pads allows you to shape and mangle the sounds produced by the slivers.

You can Automate every control.

Sliver uses Apples UIKit Dynamics to create physics on the XY Pads, allowing customized settings for the controls to shape the sound randomly with physics.

Sliver supports Audiobus, sitting in an input slot.
You can import samples via AudioShare import or Audiocopy.
You can resample, record your own samples via the Mic, or do both at once.

This app uses Background Audio and Records from the Mic. You will see a red bar when placing the app in the background.

Sliver supports MIDI learn and is fully controllable from Virtual, Network, and MIDI hardware.

Make some noises, mangle some sounds, create your own soundscape.

What’s New

Version 1.07

MIDI ADSR uses an envelope on audio that Sliver is generating. This envelope is triggered by receiving MIDI note on information.
MIDI ADSR is now off by default when opening Sliver.
When you turn MIDI ADSR on it will display a status message while on.
This change is to avoid confusion while MIDI ADSR is on and not receiving MIDI data, it appears that Sliver does not produce audio.

A real sleeper

Great unique little app, industrial music for industrial people. Can be unwieldy at times but fun to experiment with. Long audio files tend to be more drifty and noisy or ambient, short audio files tend to be more musical. I love that the dev keeps updating it, unlike many bigger devs on Apple Store I could mention. Thank you Alex M.

Textural and interesting.

Sliver is essential for those involved with any sort of ambient/drift/drone/minimal experimental recording. The use of assignable incremental sections is brilliant and yields some very interesting results. The apps functionality is great. I've been using Sliver heavily and have experienced very few problems, if any. Takes a bit of exploring to unlock its full potential which is fun. Love how it works with audiobus and IAA straight into audio share which is a nice feature.

I would like to see an update featuring mutable and/or assignable effects parameters (being able to alter the pitch bend range for more subtlety), and longer sample time for more variety. Would love to speak with the developer if I could!

All in all a fantastic app that should really be getting more attention! Highly recommended

Will not load in effects slot in AUM. Launching in background crashes AUM on iPad Pro. Frustrating.
