The Androsynth Demo is a free Android app for sampling, mixing on tracks and applying effects. The sampler is really easy to use, it has mono recording, zooming until the wave becomes flat, file browser, fast buttons, volume slider and a play button close to the volume displays. The multi-track session has 4 tracks in the beginning, but you can always add more, mute and single tracks, zoom, fast forward, set tempo, save and view the timeline time in seconds. The effects are displayed on a node editor and there are many effects you can use from Wah-Wah, Vibrato to Triangle and Sawtooth waveforms. The app has a lot of settings and is a really professional app that can output audio you can use later in other projects. This app is like the Cooledit of Android even in the free version and even more complex with the waveforms. The app is great to use with both new and outdated Android versions as it does not have a really new template. The Androsynth app is a really functional app that can be used with both tablets and phones.
