Audio transfer failed (failed to transfer from device to LENA SP Hub)

Audio transfer is the step where the recorder contents are transferred to the LENA Hub, in preparation for upload or processing.

If audio transfer begins but can't finish, an error appears. Clicking the error shows this message:

LENA Hub

The recording is safe on the device.

Close the error message and try the following.

1. Rule out an audio storage problem.

The most common reason for audio transfer failure in LENA SP is a problem with the custom WAV storage. If Hub cannot store the audio, it fails the transfer entirely, leaving the data on the device.

If all transfers are failing, and your program saves the WAV and UPL, check the following:

Is the storage path accessible to LENA Hub?

Check the audio storage settings. The location should be C:\LENA_New_Audio (recommended) or another folder directly under C:\. It should not be a user-specific folder such as My Documents, or a network folder, or just the C:\ drive with no folder, as that will cause the problem you are experiencing. Read more about why here.

If you see a different storage path, change it and try the transfer again.

Do you have enough disk space?

Typically Hub notifies you that the hard drive is too full via an alert on the Disk Usage icon on the main screen; however, the alert can be missed if the user is queueing up multiple devices and the limit is hit midway through the session.

If your drive is full, you'll need to delete or move files to make space.

2. Check the device.

If the problem is limited to a single recorder and others transfer normally using the same equipment and port, the micro-USB port or other recorder component may be the culprit.  

  1. Disconnect the recorder and power it off.
  2. Power it on again after a few seconds, and verify that the screen message is as expected (Memory Full or Paused with an elapsed time counter). If there is an error instead, address that first.
  3. Reconnect the Memory Full or Paused-with-data device and attempt the transfer again.

If transfer still fails for just the one device, please contact LENA Support and provide the serial number of the recorder to determine next steps.   

3. Check the peripherals.

If audio transfer fails for multiple recorders even after verifying the audio storage path (or determining that you're not storing audio), the problem is likely with the USB cord, part of the Multi Dock, or the USB port on the computer.

  1. Try a different USB cord.
  2. If using a LENA Multi Dock:
    • Check all connections.
    • Try a different Multi Dock, or remove the Multi Dock and try connecting the device directly to the PC using one of the USB cables.
  3. Try a different USB port on the computer if possible.
  4. Try restarting the computer.

You can also send your LENA Hub logs (desktop-main.log and lenaService.log) to LENA Support, with a description of the problem you are having, so that we can review for clues. We may ask you to try running LENA Hub as administrator.
