Augmented Code is concentrating on writing beautiful applications and games on iOS and macOS with performance and elegance in mind.
Signal Path is a beautiful and swift spectrum viewing app. It makes easy to look through hours worth of data finding interesting signal peaks in long recordings (computing spectrums is backed by SIMD and GPU (Metal)). In addition Signal Path allows recording audio data through microphone and supports FIFO channels for importing complex signal data from any source.
Control how spectrums are represented
Use FFT settings popover to change FFT lengths, window functions, data types, sample rates, center frequencies and frequency offsets.
Fast Fourier Transform lengths from 256 to 8192.
Record audio data
In addition to viewing recorded spectrums Signal Path supports recording audio data from a connected microphone.
Have fun discovering what is going on around you.
Compress and decompress data
Scale data by merging multiple spectrums into one or duplicate spectrums onto several lines enabling fine-grained look on the data.
Note: When merging multiple spectrums into one maximum spectrum points from the set are presented.
Automatic data type selection
Using a file name format _.iq Signal Path is able to automatically choose IQ data type when first time opening a file.
Supported data format descriptions in file names:
- i8, int8
- u8, uint8
- i16, int16
- u16, uint16
- i32, int32
- u32, uint32
Note: IQ data type selection is persistent and needs to be done only once.
FIFO channels for importing data
Signal Path supports FIFO channels for importing data from any source.
Create FIFO recording by using File->New FIFO Recording menu item.
File path to the channel can be conveniently copied using Edit->Copy FIFO Path menu item.
Easiest way of testing it out is by using Terminal command:
echo "$(cat /path/to/existing/file/containing/data)" > /path/to/fifo/channel
cat /path/to/existing/file/containing/data > /path/to/fifo/channel
Give it a try
Try out Signal Path with this example file.

Picker is used for presenting a selection consisting of multiple options. UISegmentedControl which is known from UIKit is just a different picker style in SwiftUI. Let’s take a quick look on how to create a form with two items: picker with default style and picker with segmented style. Creating a from Form should be typically …
SwiftUI provides wrappers for UIViewController and UIView on iOS. Same wrappers are also available for AppKit views on macOS. Let’s see how to use those wrappers for rendering UIKit views in SwiftUI previews and therefore benefiting from seeing changes immediately. Note that even when a project can’t support SwiftUI views because of the minimum deployment …
iOS apps can add quick actions which are displayed when force touching on the app’s icon. We’ll add quick actions to my open source WaterMyPlants example app. Quick actions can be static and dynamic: static actions are defined in the Info.plist and dynamic actions are configured in the code by updating UIApplication’s shortcutItems property. In …
