We’ve been keeping our magical digital signal processing elves busy here at Superpowered HQ. So super-busy that we’ve surgically embedded IVs into their little elvish arms to mainline Red Bull and espresso 24/7. Just like Santa Claus, we make our little elves suffer for YOU, so that we can deliver the Superpowered audio developer community a few important holiday presents before we close this year out.
Our first super present is The Superpowered Audio SDK is now FREE for all apps regardless of install or user base.
There is no need to calculate downloads and fees: your audio apps will be blessed with super powers without limits like commercial quality free time-stretching and pitch-shifting. You can read the details of the Superpowered Audio SDK license here.
Our second super present is we’ve significantly extended the audio SDK with advanced music analysis software features. The Superpowered Audio SDK is the first audio library to offer:
All in the same package, for free! Let’s dig into the details.
A bank of bandwidth bandpass signal filters. Perfect for real-time analyzers (RTA) or offline usage. Very simple to use: just set up the frequencies and widths, and call process(). In addition to the frequency bands, the sum and peak of the incoming signal is returned too, so you get the average and peak volume.
Note: An online analyzer is on the Superpowered feature roadmap; meanwhile you can use the SuperpoweredBandpassFilterbank for RTA.

Simplified parameters. Just set the 3 bands (simple float variables) and that’s it. Kill is enabled for a band under -40 decibel (0.01f). A bit more on the Superpowered 3 Band Equalizer for Android and iOS.
Pause method is enhanced with optional decelerate parameter for stopping with momentum. Works with slip mode too. Good for turntable motor effects. Check out the Superpowered Advanced Audio File Player.
New method to search for the first audio sample. Good for cutting initial silence. Parameters: how far to search for, loudness threshold. A 0 loudness threshold will cut digital silence, while -49 decibels is good to search for the beginning of vinyl rips.
Superpowered Audio Decoder is here.
The Apple 8.24 format conversions are removed as this format is officially deprecated. New feature: processPFL method to create a pre-listening signal for any mixer, with channel switches and optional channel output level processing.
