USB Audio Recorder PRO

Last update: 15th of June, 2013

Introduction

The Android app USB Audio Recorder PRO allows you to record and playback audio using class-compliant USB audio devices on your Android phone or tablet! eXtream Software Development has written a custom USB audio driver from scratch because Android does not support USB audio (even Android 4.1 contrary to popular believe!).

Supported are mono and stereo streams, 16-bit and 24-bit and any sample rate (up to 192kHz) that the device provides. If your device exposes internal mute, volume and/or gain controls, they will be displayed in the Mixer tab.

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, or the 3 top-right combo boxes are not filled, 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'. 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. We will create a Service in the future that does not have this issue though.

We are also NOT affiliated with a program called 'USB Audio Recorder', 'USB Audio Tester' or 'USB Field Recorder' on the Play Store!

Troubleshooting

Ok, so you connected your audio device before starting USB Audio 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.
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 for instance). Try to disconnect the cable and reconnect it, start the app, see if it helps.
Reboot your Android device

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.
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).

If that didn't help and you are sure you have an Android device with USB host mode and it isn't some China Rockchip-based tablet, 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 Recorder PRO and Force Close it.
Start the app again and exit it again.
Please email the log file /mnt/sdcard/USBAudioLog.txt (or simply USBAudioLog.txt in the root of your device) to info AT audio-evolution.com

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.

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.
