USB audio driver in USB Audio Player/Recorder PRO and Audio Evolution Mobile
Last update: 19th of November, 2015
eXtream Software Development has written a custom USB audio driver from scratch because Android did not support USB audio until Android 5. Even Android 5 has very limited support for USB audio devices (see below) and as such this driver remains a very useful for every Android version higher than 3.1. The driver supports mono, stereo and multi-channel streams, 16-, 24- and 32-bit resolutions and any sample rate that the device provides. If your device exposes internal mute, volume and/or gain controls, they can be controlled as well.
The following Android apps of eXtream Software Development use this driver. Note that you cannot use this driver to play/record audio in other apps!
Audio Evolution Mobile is the leading multitrack audio and MIDI DAW on Android. You can enable USB audio by doing an in-app purchase or purchasing USB Audio Recorder PRO.
USB Audio Player PRO is a high quality media player that allows the highest quality possible audio playback to your DAC and supports more audio formats like mp3, album/artist browsing, playlists and more.
USB Audio Recorder PRO is a basic recording app without editing facilities. Record mono, stereo or multi-channel audio and play back in stereo. Simultaneous playback and recording is not supported.
Free trials are available in the app's descriptions.
USB host OTG cable
In order to connect your USB audio interface to your Android device you will likely need a USB OTG cable to trigger the 'USB host' functionality of your Android device. This is the cable you need:
or if you need to give your audio device extra power, you can either use a powered USB hub or this OTG-Y cable:
This cable is similar to a standard USB OTG cable with a full sized female USB connector on the end that connects to the audio interface, but it branches off into 2 connectors on the other end. One is a standard male micro USB connector for connecting to the android device and the other is a female micro USB connector. The female micro USB connector allows the ability to plug in a standard male micro USB wall charger to inject power into the circuit.
Note: some devices require 500mA while some Android wall-adapter power adapter only supply 300mA, so using an OTG-Y cable will not help and a powered USB hub is necessary.
Do NOT use or buy this one:
When you order a cable, make sure it says 'OTG'.
Starting the app
Important: connect your device BEFORE starting the app, otherwise it will not get detected! When you connected your device before starting the app and it gave you a 'failed to initialize or open the USB device' message or similar, we ask you kindly to quickly use the Play Store refund option in case you purchased the full version and try out the demo. Please contact us if your device does not work.
Hint: for most reliable recording, put your device into 'Airplane' mode and shut down as many tasks as possible using task killers such as 'Advanced Task Killer'. Please also disable any battery saving mode if present. Currently, USB Audio Recorder PRO has to run in the foreground, so do not switch to other apps during recording or playback since background apps only get 5% cpu time max. This does not all apply to USB Audio Player PRO, but it can help nevertheless.
We are also NOT affiliated with a program called 'USB Audio Recorder', 'USB Audio Tester' or 'USB Field Recorder' on the Play Store!
Ok, so you connected your audio device before starting USB Audio Player/Recorder PRO and it still doesn't work, what to do?
If both your Android and USB device are in the supported devices lists:
- Some devices require more power than your Android device can deliver. If your audio device is bus-powered (so no wall adapter) you could try putting a powered USB hub in between.
- Some devices require you to turn on USB debugging from the Android settings -> Developer options. Please let us know if yours does.
- If you have a micro-USB port on your Android device, make sure you really have an OTG adaptor cable and not some sort of simple USB type converter, otherwise USB host mode is not activated.
- It happens more often than one thinks that the micro-USB cable is not fitted fully into the micro-USB port. Make sure it fits really good and if your audio device has a blue USB light, check if it turns on when you connect it to your Android device. If it is not lit, then either the cabling is not right or your audio device consumes too much power. Note that the USB light must already be lit BEFORE starting the app.
- Some devices are just picky (FiiO E17/E18 for instance). Try to disconnect the cable and reconnect it, start the app, see if it helps.
- For the FiiO E17: try to cycle the input until it is at the USB input again, do this before starting the app, but with the USB cable connected
- Go into Android Settings -> Storage -> tap on the menu at the top right and select USB computer connection and see if MTP is enabled
- Reboot your Android device
- Buy another OTG cable, it happens so many times that people switch cables and things start working again, it's surprising.
If the app recognizes your device and all looks ok until you press play or record and nothing happens or no signal comes in:
- Your Android device supports USB host, but something is missing in the kernel (or perhaps the hardware) that prevents the use of the required USB isochronous mode for transferring audio data. Device detection is done using other types of communication, which is why it did get detected.
If the app recognizes your device and all looks ok until you press play or record and then you get a 'Failed to start recording/playback':
- Check if the kernel version of your device is at least 3.4.0. Some older versions have a bug which results in a wrong USB bandwidth calculation. Using a multi-channel device or simultaneous playback and recording can then result in this message.
If your Android or USB device is not in the list:
- Make sure your Android device has USB host mode: Google your device like 'Acer Iconia A100 USB host mode'. If you find hits saying it doesn't have USB host mode, then your device will not work. If you find hits stating that a custom kernel can activate USB host mode, then your device will not work unless you have that specific custom ROM.
- Use the app 'USB host check' to find out if your Android device is properly configured for USB host: https://play.google.com/store/apps/details?id=org.tauruslabs.usbhostcheck Red crosses may indicate improper configuration and on rooted devices, this app can make an attempt to fix that configuration. Of course, the hardware must have support for USB host mode in order for this to work. Note: the USB host check app is often wrong. If the first check gets a green check mark, it is usually ok.
- Make sure your USB device is class-compliant: Google your audio device to check if it works under Linux since it then has a bigger chance of working (not that we use Linux drivers or also, but they usually have class-compliant devices working).
- Check if your device has a Rockchip processor. Most Rockchip processors except the RK3188 do not support USB host.
- Most cheap unbranded/unknown/Chinese tablets do not work. If it didn't cost 150 euro or more, it is likely it doesn't have the hardware needed.
If that didn't help and you are sure you have an Android device with USB host mode, you could send us a more detailed log by following these steps:
- Open the app
- Select the Prefs tab
- Select Logging
- Select Log to file
- Exit the app
- Go into Android settings -> Apps, select USB Audio Player/Recorder PRO and Force Close it.
- Start the app again and exit it again.
Google introduced USB audio support in Android 5, unfortunately our tests have shown that their driver has several limitations. Please see here for more information:
Supported USB audio devices
Your USB audio device must be class-compliant in order to work. USB 1.1 and USB 2.0 class-compliant devices are supported with either USB audio spec 1.0 or 2.0. The following table gives an overview of the devices that either we tested or that have been tested by beta testers. In no way we can be held responsible for a device not working on your specific Android device, since every combination can pose new problems. We have a free demo version where you can test out your device combination before purchase.
Please take note: because there are hundreds of Android and USB audio devices out there, we did not manage to test them all. In case yours does not work, please use the 'feedback' button on top to send us information on your device or contact us by email. When you start recording and you get a message saying 'Failed to start recording', it is likely that your device does not supply enough power to your USB audio device if it is not self-powered. You can work around it by putting a powered USB hub in between.
Notice for Samsung users (10 October 2015) : we have been getting reports that an update to Android 5.1.1 will cause USB Audio Player PRO to crash on start-up. This is caused by a security exception from Samsung, blocking access to all USB devices from apps. We do not see this on the Samsung S6 and it has been reported so far for the Tab Pro 12", Tab 4 7" LTE and S5 models, but if you can, please do not install a system update until Samsung solves this problem. We have filed a bug report to Samsung, but we'd appreciate if you also complain to Samsung about this if you experience this problem so that it has a higher chance of getting fixed. Note that the problem also occurs on similar products, so it's definitely not a bug in the app.

Supported Android devices
In theory, all Android devices that meet the following requirements should work:
- Android 3.1 or higher (no root required!!)
- Device supports USB host mode
If your device does not have a full-sized USB port, you need a USB OTG cable. This is cable with a male micro-USB connector on one side (for connecting to your Android device) and a female full-sized USB port for connecting your USB audio device. Note that it must say 'OTG', since that activates the host mode of your Android device.
If your device is not in the working or non-working list, please give us feedback if it works or not.
NOTE: Samsung either blocks USB audio devices on their S1, S2 and Note1 or did not put isochronous transfers in their kernel!
NOTE2: your Android device may need a powered USB hub if it does not supply enough power to an audio device which is not self-powered.
