Recording Audio

Recording is pretty simple: you press the red Record button at the bottom left and the program will start recording. You will see the recording level in the mixer channel of the track.

There is one thing to note here: when you press Record, a new track is automatically created and the audio is recorded on that track. This is a convenience function: in most desktop DAW's, you first have to 'arm' the track you wish to record on. Audio Evolution Mobile will detect if you have any track armed. If not, it will simply create a new track to record on for you, unless you have disabled this feature in the preferences. If a track is armed, it will record on that one. Arming a track is done by toggling the Arm button of the track's mixer channel in the left pane: this button has a red circle on it. If your device has a small screen and is not showing the Arm button, you can access it by browsing the mixer channel pages: at the bottom of every mixer channel, you will see a couple of dots. Slide your finger over here to access the other mixer pages to get to the Arm button.

Android specific: Only one track can be armed at a time unless you use a multi-channel USB audio device.

If you don't like the recording, you can get rid of it by pressing the Undo button. Note that the recorded file remains on your device's storage. You can also remove a clip by selecting the Remove mode button on top and tapping on the clip you wish to remove.

Starting recording and playback in the middle of a song

You do not need to start all your recordings at the beginning of the song/project (00:00:000). Use the green time marker at the time code area on top of the time line to set your starting position and press Record. Recording will then start there.

Input gain control


When using the Android audio system (internal mic or headset)

Our policy on gain control is not to deceive our customers by providing a software gain control like some other apps do. There is no function in Android that allows an app to set the input gain, how unfortunate that may be.

Now, we could either implement a software gain where only increasing gain has a use, but we feel that in this way you could also easily distort your signal. The better solution for making audio louder is to use our offline 'Normalize' effect that will prevent any unnecessary distortion that could result from too much software gain during recording. You can find the Normalize feature by long-tapping an audio clip in Scroll mode and selecting 'Apply effects' and then 'Normalize'.

Turning off automatic gain

Usually, Android applies automatic gain control. However, you can turn this off in the app's preferences by selecting 'Mic, no processing, lowest latency' for the 'Audio input' preference.

When using a USB audio interface

When using a class compliant USB audio interface with our own driver (in-app purchase required), the gain can almost always be controlled on your audio interface or by using the hardware mixer screen. Please read here on our USB audio support!

Using the headset input

When you do not connect anything to your Android device, the internal microphone is used. You can however, connect a headset to the mini-jack input: this needs to have a 4-pole TRRS connector for stereo headphones and a mono microphone. This works on the majority of devices. This method can be beneficial, because when using the internal microphone and the speaker of the Android device, the mic may pick up what is playing back through the speaker! When using a headset, these signals are separated. Note that you can also use devices like IK Multimedia's iRig line of mics/pre-amps as well, which have the 4-pole TRRS connectors as well.

There exist adapters with two 3-pole female connectors (mic+headphones) and a 4-pole male connector. This can sometimes work as well, but we do not have enough data on which ones work on which Android devices.

Note for Nexus 7 users: the connector on the Nexus 7 is for headphones only!


The input gain can be set in the app's preferences under 'Input gain'.
