5 Best Oscilloscope App iPhone

1. Loopy Pro: Looper DAW Sampler

Download the App on the Apple Store by clicking this Button
“Loopy Pro is a live-looper. And a sampler. And a sequencer. And a very capable AUv3 Audio Unit host. And a DAW. And an AUv3 Audio Unit.

You get the idea. Loopy Pro is deep. But it’s also designed to be friendly, and a great deal of fun.

You can set up Loopy Pro to work however you do, with features like hands-free looping with count-in, count-out and automatic loop detection; or “free” looping, where you can choose on-the-fly how long to make loops. There’s even retrospective recording, where you can lock in a loop after the fact.

There’s extensive MIDI controller support, including built-in support for the Launchpad and the APC40 mk2, and effortless MIDI Learn for setting up your controllers.

You can also drag-and-drop audio straight onto loops in Loopy Pro, with sophisticated tempo and pitch adjustments, and use Loopy Pro as a clip launcher, with all kinds of options for song sectioning.

The built-in mixer lets you set up insert and send effects for every channel in your project, and load AUv3 Audio Unit instruments, effects, and MIDI sequencers.

And there’s a built-in sequencer, for arranging songs, and even performing them live, totally automated and hands-free.

There’s also a great deal still to come.

So, what are you reading this for? Go take Loopy Pro for a spin – there’s a 7-day free trial just waiting for you.

Have fun!

Loopy Pro’s Pricing Structure:

Loopy Pro has a pricing structure that mimics the classic desktop software model, in order to enable continued development:

• A 7-Day Free Trial, so you can make an informed purchasing decision.
• A one-off In-App Purchase to buy the app: to keep, forever.
– This gets you permanent access to all current features, and all those added in the following 12 months.
– It also gets you bug and compatibility fixes for the lifetime of the app.
• A completely optional “Upgrade” In-App Purchase, available any time from 12 months after initial purchase, to buy the latest features and all those released in the following 12 months, to keep forever. Upgrade once, or every year, or just when there’s a new feature you want, or never upgrade after the initial purchase – it’s completely up to you. And you keep what you buy, forever.
• This will allow Loopy Pro to continue evolving for years to come, while letting me support my family.”

“This application turns your computer into a powerful oscilloscope for audio signal analysis (professionals can also use for circuit analysis).
The signal parameters can be displayed in detail, including: maximum value, minimum value, average value, effective value and frequency, and the frequency measurement is very accurate.
There are multiple trigger modes. The trigger modes are: automatic mode, normal trigger and single trigger; the trigger edges are: rising edge trigger, falling edge trigger, rising or falling edge trigger, jump trigger and differential trigger; the trigger value can be selected.
With the measurement function, it is freely measured in the horizontal and vertical directions, gesture operation, easy to use.
Waveforms can be freely zoomed with gestures or buttons.
Supports interface color selection.
Has a storage depth of 10 seconds.

This application is normally used for audio signal measurement without any risk.

Circuit measurement special instructions:
Professionals can use this application for circuit measurements and the electrical signal is input via the microphone channel of the headset.
Please pay attention to safety: You must have enough professional knowledge. The high voltage circuit must go through the isolator and attenuator. Conventional low-voltage circuits must also add an attenuator and then enter the phone.
Circuit measurement is risky and the author of this application will not be liable for any loss of personnel or equipment resulting from the correct or incorrect use of this application.”

“”I use this for analog, and audio measurements. Attach an Apple USB adapter and a $40 stereo A-D converter available online, and my iPad is like a $300 O’Scope.” -thymeout-

Oscilloscope app is great for analyzing audio range signals, or learning oscilloscope measurement basics. The interface includes many standard oscilloscope controls, such as: triggering, time and voltage per division, signal measurement cursors, and more.

The app incorporates a signal (function) generator capable of generating sine, square, triangle, and sawtooth waveforms of up to 22 KHz. Calibration to an external reference signal is supported, guaranteeing the accuracy of measurements.

Input can be acquired via the built-in microphone or an external mic/probe connected to the headset connector. For best results, use an external audio interface connected to your device dock. This allows for standard audio equipment to be connected, as well as for dual channel input. Oscilloscope probes also be connected (using a BNC connector). When feeding external signals via probes, you should take care not to exceed 1V AC voltage. Currently iDevices support only AC input.

4. Oscilloscope & Spectrogram

Download the App on the Apple Store by clicking this Button
“OSCILLOSCOPE & SPECTROGRAM is a powerful audio analyzer app and audio unit plugin

– Run as both Audio Unit and standalone app
– View up to three seconds of audio on the screen
– Pause and scroll horizontally to browse back in time
– Pinch to zoom in / zoom out
– See both oscilloscope and spectrogram separately or overlayed together
– Frequency trigger mode helps identify the precise frequency and MIDI note of sounds in the spectrogram
– Stereo and mono views
– Level based trigger mode has lookahead, pause, and zoom
– XY mode shows stereo correlation
– Automatically adjusts FFT size to fit zoom setting
– Bark-frequency scale spectrogram shows nice detail at low and high frequencies
– When zoomed in, the oscilloscope uses sinc upsampling to show you a close approximation of what actually outputs from your audio interface after digital to analog conversion, rather than just displaying raw audio samples.


1. Pause Button

We can’t emphasize enough how useful this is. You never have to worry about trying to catch short events that disappear quickly because you can watch the sounds go by slowly at a 3 second viewer scale, then just pause and scroll back if you missed something. When you get to the event you want to see you can pinch to zoom in right down to sub-sample level of detail, then zoom back out when you are done and zoom in on something else. This feature alone makes almost all other oscilloscope apps unnecessary because it means you can easily see ANYTHING that you need to see.

2. Frequency Identification Mode

In frequency mode, when you touch the frequency scale on the right of the screen a blue line appears on the spectrogram. When you position the line above a specific frequency on the spectrogram, a panel on the left side of the screen displays the octave, note name, and MIDI number. You can then use the frequency timing oscilloscope to lock in on the exact pitch in cents so that you not only know which MIDI note that sound corresponds to but you know exactly how many cents sharp or flat. The ability to simultaneously see the frequency on the spectrogram and confirm it with precision on the oscilloscope allows you to quickly and easily identify musical pitches to a level of accuracy that have not seen anywhere else, not even in desktop software.

3. Trigger with Lookahead

Almost every oscilloscope has a feature where it re-draws the screen each time the input signal level crosses a specified threshold. This is the main and most basic function of any oscilloscope. However, when setting the trigger at a high level to view the attack section of musical notes or drums, we miss the first part of the note. By using lookahead, this app allows you to see a few milliseconds BEFORE the trigger point so that you can see the whole sound you want to examine.

4. Carefully Designed Spectrogram

In all spectrum analyzer displays, the upper end of the frequency scale is crowded, meaning that a single pixel corresponds to 10 or 20 frequencies in the frequency analysis. In many other analyzer apps one of two things occur: either 9 out of 10 frequencies in that upper range simply get ignored and disappear from the spectrogram display, or all 10 frequencies combine together to make the pixels in the upper range appear brighter than low frequency sounds of similar volume. This may seem like a technicality until you run a sine sweep or a 20 KHz tone through the analyzer and find that large sections of the input simply aren’t displayed on the analyzer screen. Looking at these kinds of test signals on a spectrogram is the primary way that we test and evaluate the quality of audio effect plugins. If a spectrogram is to be of any real use as an analysis tool, it should do this right. Other spectrograms often mess up the lower frequencies too, either by making them take up too much space or by making them very pixelated. This spectrogram carefully avoids these problems.”
