Sample your voice, musical instruments, and ambient sound. Create a multi-timbral synth by combining samples from different instruments.

Auto Sampler combines pitch detection, sound sampling, and wavetable synthesis into easy to use app that runs on any iOS device with a microphone. Samples are automatically extracted from live audio through the microphone input (built-in or external). The pitch detector assigns a pitch to each sampled sound, which is displayed on a piano keyboard as it is captured.

A polyphonic multi-timbral wavetable synthesizer resamples and blends samples into a continuous palette of sound. The synth can be played with the built-in keyboard, and from other apps via Audiobus MIDI. Controls adjust blending, modulation, attack/decay, and other parameters.

A small string orchestra constructed from public domain samples is provided to get you started.

Can also import certain WAV files (see documentation). Compatible with our OASIS app for creating samples from your iTunes library.

Unusable App

Unfortunately, this is a very disappointing and horrible app, it’s actually unusable. All samples make a loud popping noise when they hit their loop point, have tried adjusting all parameters, and cannot get rid of this artifact. Tried contacting developer, no response. I am a professional electronic musician, and electronics geek, but could not make this work, I’m using an iPhone 8 with plenty of memory.

Hoped to use this as a vocal sampler. It DOES record voice. But any words said are unintelligible. Certainly NOT a vocoder. Samples include are sub-par. Only uses .wav file format. Waste of money for what I wanted,

Create Sample Sets

The app does a really good job of recording from the mic and assigning the samples to the appropriate key of the keyboard which you can then play or use midi. It does this all in one take with the mic. It would be really nice if you could create samples by placing the app in the output slot of Audiobus. You can load multiple sample sets to create layered sounds. Hopefully in the future there will be more ways to add samples via copy and paste.
