Superpowered Inc develops the leading portable C++ Audio SDK, C++ Networking SDK, and C++ Crypto SDK featuring low-power and real-time latency. With builds for Desktop, Mobile, IoT and Embedded Devices, portable and cross-platform on Android, iOS, macOS, tvOS, Linux and Windows as well as processor-specific builds for ARM32, ARM64, x86, and x64.
Superpowered Inc develops the following interactive audio, networking and cryptographics SDKs and infrastructure:
Superpowered C++ Audio Library and SDK is the leading C++ Audio Library featuring low-power, real-time latency and cross-platform audio players, audio decoders, Fx (effects), audio I/O, streaming, music analysis and spatialization.

The Superpowered C++ Networking Library and SDK was designed from the ground-up to provide the easiest cross-platform way for a client to communicate with the back-end. It implements HTTP and HTTPS communication with custom data and header support, progress handling, file uploads/downloads and more. It reduces implementation, debug and maintenance time of typical tasks such as REST API requests, OAuth and bearer token authorization, or digital media streaming. It operates identically on all platforms, removing the pain of writing wrappers and finding quirks around the operating system's networking API, while it's fully self-contained and independent from it. The SDK also has a JSON parser to offer a complete package for your everyday networking and parsing needs.

Superpowered Crypto offers the easiest cross-platform way to implement RSA public and private key cryptography, AES encryption and hashing functions (SHA, MD5). Unlike other cryptographics libraries designed for crypto enthusiasts with myriads of options and complex APIs, Superpowered Crypto has direct one-liner calls for signing, verification, encryption and decryption, solving the most common use-cases in the quickest way.

The Superpowered USB Audio and MIDI features for Android takes over MIDI device handling, providing low latency and low jitter (below 2 ms) access to MIDI devices for 1.4 billion Android devices, that is, 90+% of all Android devices on Google Play. It’s the Android equivalent of iOS Core Audio and Core MIDI for USB devices.

It compares several Superpowered features to Core Audio.
Shows the differences between Superpowered and Core Audio.
Syncs effects to the player's bpm.
Shows how to use Objective-C++ in an Objective-C project.
Swift note: We have also tried creating this project in Swift, but it's not complete for audio and several features were impossible to implement (such as proper performance measurement). Swift is not designed for real-time audio. Fortunately, Objective-C++ files work great in Swift projects.
Shows how to use a single effect (input -> fx -> output).
Shows how to use a player (for local, progressive download or HLS playback).
Shows how to record the microphone input using SuperpoweredRecorder.
Simple ambisonics implementation based on the SuperpoweredSpatializer.
This project comes with two example apps, a simple and a complex example app.
The simple example app demonstrates an easy audio setup, similar to how iOS handles USB audio devices. It also receives and displays MIDI. The audio functionality of the simple example app will cover most mobile audio use cases.
The complex example app demonstrates full USB audio discovery, for the use case of sophisticated DAW and recording apps. It displays the various input and output options, audio paths and hardware controls of a USB audio device. Hardware controls can be manipulated and advanced thru audio paths can be enabled.
If an audio output is selected without an audio input, the complex example sends a sine wave to every output channel. If both audio output and audio input are selected, then loopback or round-trip latency measurement are available.
This means that the complex example app is also a testing tool to discover a USB audio device’s advanced features, test audio quality, glitches and latency.
Superpowered USB Audio classes for Android are compatible from Android 19 (KitKat 4.4) onwards. That’s the first Android version where proper scheduling priorities were implemented for low latency audio. This covers more than 75% active Android devices today.
Before running any Android example project, please set up the appropriate Android SDK and NDK paths in File - Project Structure... Furthermore, turn off Instant Run in the settings, because the Instant Run feature of Android Studio is not compatible with native C++ Android projects.
Prerequisites: latest Android SDK, Android NDK, Android Studio installed. Steps:
