Augmented Code is concentrating on writing beautiful applications and games on iOS and macOS with performance and elegance in mind.

Signal Path

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 with a microphone and replaying the recorded audio. Additionally supports FIFO channels for importing complex signal data.

Signal Path is available for macOS, iOS, and iPadOS.

Advanced feature: 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:
macOS 10.13: echo "$(cat /path/to/existing/file/containing/data)" > /path/to/fifo/channel
​macOS 10.12: cat /path/to/existing/file/containing/data > /path/to/fifo/channel

Adding prefixMap for expensive operations in Swift

Swift Foundation contains a lot of useful functions on collection types. In the context of this blog post we are interested in map(_:) and prefix(while:). Map is used for transforming collection elements and prefix(while:) for getting a sequence containing initial elements until the predicate is true. In some cases the predicate used in the prefix(while:) …
