SampleWiz was awarded Music Making App of the Year for 2011 by the Music Industries Association! Capture your sonic universe! Listen… Record… Create… Jordan says: In creating this instrument I wanted to create something that would appeal to the sonic explorer in all of us. Creating a sampler for iOS devices has allowed us to push the boundaries of traditional sampling instruments. From playing a selection of my signature sounds on the SampleWiz keyboard (JR lead anyone?) to getting up close and personal with sounds by playing directly on the waveform screen, our mission was to blow your mind, put a smile on your face, and expand your creativity. In creating SampleWiz, we have created partnerships with leading sound developers in addition to my personally selected onboard presets. "Inspiring! Just when you thought nothing could be new in the world of sampling, along comes SampleWiz to fire up the neurons of our creativity in new ways. I love the the new realtime interactive noises I can get by 'touching the sound'...the crazy and unique stuff you can do with it is really expressive and fresh!" - Eric Persing, Founder of Spectrasonics "SampleWiz gets you playing instantly, and if you like to sample, there's no quicker or more fun way to go from recording to playing your own samples. Amazing controls, easy to understand yet deep enough to let you create musical voices! And it comes with a library of great sounds from Jordan Rudess. SampleWiz is a wiz if ever there was!" - David Mash, VP of Technology and Education, Berklee College of Music  We have poured our hearts and minds into this and driven our families, bandmates, and friends insane by sampling everything that moves. I hope you enjoy this very expressive and wild music app creation! *Choose from three different sampling modes: classic, granular, and modern. *Classic - the traditional method of sampling where the sound will speed up and slow down as you go higher or lower than the recorded pitch. *Granular - Wizdom Music's own take on a granular synthesis engine. Adjust grain size and speed while the entire range of notes maintain the same speed. *Modern - explore new sampling possibilities using Dirac technology to allow formants and time to be adjusted automatically over a device-selected range. *Up to 10 seconds per sample. *Jordan Rudess presets from his private collection. *Resample anything that you play on the playing surface to create all new samples derived from your existing presets! *Three playing surface modes allow you to play on the keyboard, wave-edit screen, and the ADSR window. *Wizdom Music's Advanced Pitch Rounding for initial attack as well as after a slide. *Every note you play is an independent event allowing powerful, expressive control of pitch and amplitude. *Finger vibrato effect allows you to use vibrato even when pitch lock is activated! *Unique visuals for each sampling mode. A glow tracks your fingers and respond to the amount of amplitude of every note you play. *Choose from many different scales and customize your own. *Play your samples forward or reverse! *Looping options include standard looping as well as back-and-forth looping. *Allows trimming of samples. *Unique visualization of the amplitude envelope on the ADSR page. *FX include delay with a choice of tap-tempo, BPM, and seconds control over the rate. *Have two keyboards on the screen, each with its own range and scale! *Unique hold mode where every held note can be in a different synthesis mode! *Share your presets with friends by mailing them as SampleWiz files or standard audio files. *Play directly on the waveform and hear the audio that is right under your finger. Slide each finger separately in any direction to change pitch and position in the sample. *MAPI AudioCopy/AudioPaste allows sharing of audio with top audio apps. *Load your own audio files with iTunes file sharing. *Onboard help screens explain every parameter.

About

Sirens' Chor

This experimental audio effect app analyzes input audio to generate a secondary harmonic voice using sine wave oscillators. The generated voice can be mixed with the original or played solo, creating a chorus effect. It's CPU intensive and operates within a specific frequency range.

Highlights
  • Harmonic analysis of input audio
  • Sine wave oscillator synthesis
  • Adjustable chorus effect
  • Second voice generation
  • AUV3 plugin support

This one is quite experimental and CPU heavy app! While working on my Chord Detector app I came up with the idea to play the found harmonics with sine wave oscillators so I can hear what the algorithm is hearing :) It turns out to be an interesting output that led me to creation of this audio effect app. What happens here is that the input is analysed for main harmonics in the range of 80Hz to 1500Hz. Then a series of sine wave oscillators are set to play those harmonics with the exact frequency and volume and their output is added to create a second voice. This second voice can then be mixed with the input to create some kind of chorus or played alone. All this is CPU heavy process so it should be used with care... Also to make this effect possible I had to use limited range 80Hz to 1500Hz so it is not suitable for every instrument and you have to keep that range in mind when producing. Some very fast volume and frequency changes are applied to the oscillators. The app is AUV3

Verdict

The call

The clearest difference is review sentiment: Sirens' Chor at 100% against SampleWiz's 63%. Sirens' Chor also leads on price ($3.99 vs $9.99). SampleWiz's advantage is rating (4.4 vs 4.0) and update cadence (every 3 months vs every 39 months). On ads, in-app purchases, monetization model and device support there is nothing between them.

SampleWiz costs $9.99 and Sirens' Chor $3.99 up front. Neither carries in-app purchases, so what you see is what you pay.

ReceptionRating · Positive reviews · Number of ratings

SampleWiz holds the better App Store score, 4.4 against 4.0. That said, the two scores are not equally well evidenced: SampleWiz has 16 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 63% of SampleWiz's written reviews are positive against 100% of Sirens' Chor's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

SampleWiz ships an update every 3 months, Sirens' Chor every 39 months. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
