Audio Evolution Mobile for Android


A mobile recording studio on Android!

The most powerful multi-track audio and MIDI recording studio on Android with support for over 250 USB audio and MIDI interfaces (*), virtual instruments(*), editing with unlimited undo/redo, mixing, real-time effects, automation and much more! Record your voice, guitar, piano or any other audio source or create beats and synth tracks using a piano roll or external MIDI keyboard.

Supporting USB audio and MIDI

Besides recording your ideas with the built-in microphone or a headset, you can achieve high quality recordings with low latency using a USB audio interface connected to your Android device. By using a custom USB audio driver which completely bypasses the Android audio system, the limits of Android are no longer applicable: record up to 24-bit at any sample rate that your USB audio interface supports and even perform multi-channel recording! See this page to read more about USB audio support.


There are a variety of tools at your disposal to edit your recordings: move, trim, split, cut, copy, paste, cross-fade, time stretch and repeat to name a few. And all these actions can be performed without worrying about touching your original recordings: every action is non-destructive, meaning that the actual cutting and splitting is not done on the actual sample data itself! We just keep references to all bits and pieces you are slicing up. And in addition, there is an unlimited undo and redo feature that will take back every step you make in case you do not like the edits you have just done.


With this unique feature on mobile, pitch and time in vocal recordings can be edited in high detail. A piano-roll like view displays audio with the same pitch as separate notes, which can then be adjusted up and down for pitch correction or modification. The retune time, retune amount, volume and amount of formant correction can be set globally or for each individual note. When needed, artificial vibrato can also be applied to each note with parameters for vibrato depth, rate and settings to adjust the time when the vibrato kicks in and the time in which it reaches the full vibrato depth to obtain a natural sounding vibrato.
Individual notes or groups of notes can also be time corrected, adjusting phrases that are off-beat. Vocal Tune Studio can detect the key and scale of a vocal recording automatically or a key and scale can be manually chosen.

Aside from vocal pitch correction, Vocal Tune Studio also features a generic time correction/stretching mode which works on any type of audio material (not only vocals, but also guitars etc.). In this mode, any part of a recording that was played off-beat can be time corrected without affecting parts that were recorded in time.

Vocal Tune Studio has been fine-tuned to provide the highest quality compared to desktop offerings and is available now within Audio Evolution Mobile Studio on Android and iOS as an in-app purchase.


Toneboosters VST effects

Besides a large collection of standard and free effects, a collection of effects from Toneboosters, well known for their high quality and affordable VST effects for PC/Mac, are available as in-app purchase in Audio Evolution Mobile! These effects include a brick-wall limiter, compressor, de-esser, EQ, noise gate, reverb and a bit crusher.


After recording your takes, importing your samples and doing some editing, it's time to balance your audio tracks, apply some EQ-ing and put some real-time effects in there! Although you can see one mixer channel in the arrange screen for the selected track, the mixer screen will give you access to all channels at once. Slide your finger over the mixer page indicator at the bottom to explore the different mixer components: volume, panning, mute, solo, arm, EQ, insert fx, fx sends, and input and output selection are at your disposal for every individual channel.

The master mixer screen allows you to manipulate the stereo master bus and you can even create multiple busses for use as subgroups of fx returns. For example, assign all your drum tracks to one drums subgroup and you can change the volume of the complete drum kit with just one fader.



With mixer automation you can become truly creative! Volume, panning, mute and all insert effect parameters can be completely automated without any user interaction: create fades or silence short sections by drawing simple curves. Create cross-fades by fading out one track while fading in the other.

Mixdown and project export

Your mix is done and you are ready to show the world, now what? Mixdown the project to a stereo WAV/FLAC/OGG file for sharing with SoundCloud, GMail, DropBox, etc. You can also export 'stems', meaning that all individual tracks are rendered to a WAV file for easy importing into your favorite DAW on your desktop. You can also exchange audio projects with the Windows version of Audio Evolution.
