Realtime Granular Synthesis for Android.

Grainstorm takes sound data as input, granulates it and pushes it back to audio out in realtime.

Input either comes from recordings over the internal mic or from audio files which the user can choose from disk and are decoded afterwards. Currently only .mp3 and .flac stereo formats are supported, the samplerate of the input has to match the samplerate of the device (which is determined automatically and is 44.1kHz in most cases) or the result will be time-stretched or time-shrinked respectively and the input file must not exceed a length of 7 minutes.

There is a cursor which can be moved over the waveform to determine the exact position from where input is taken. The waveform can be zoomed in until one sampleframe per pixel is displayed. Thus the cursor can be moved as exactly as one sample if required.

The two other cursors determine start and stop position of playback. In combination with playbackspeed and the other parameters evolving sound textures, morphing over a short or long period like hours can be created.

Interesting results - always depending on what you take as input - which could be used for electronic music production can be achieved if input comes from sampled voices or synthesized sounds samples.

Output can be recorded by pressing the record button. On the second press the recording is automatically saved in .wav format in the user's music folder.

Grainstorm performs pretty well on recent devices with multi-core CPUs. The DSP-part which is highly optimized and most of the GUI-part are written in C - interaction between both is fast.

Before downloading the unlocker you should make sure that Grainstorm works satisfyingly on your device. It is not recommended for "slow" devices. If you encounter clipping turn out all background services. If you still encounter clipping, then Grainstorm might not be suitable for your device.
