The issue applies to:
QuickCam© 9.x
QuickCam© 10.x

The information applies to the following Logitech© devices:
All RightSound capable video devices

Issue:
After Installing QuickCam, 9.x or above, MuvAudio recorded files are deteriorated and recorded in "slow-motion". The following anomalies may be observed:

  • Hardware Acceleration is partially disabled

Reason:
This specific issue is related to Logitech’s RightSound Technology. RightSound Technology was designed to improve the audio communication experience and is not optimized for multi-channel audio, games or any advanced audio usage. To provide advanced communications capabilities such as “Echo Cancellation” it has to restrict the way certain audio features are used.

When the AEC feature of QuickCam and supported cameras is enabled, the recorded audio may be restricted causing some audio files recorded by MuvAudio to be deteriorated and playback slower than the original.


Solution:
Disable RightSound technology or the “AEC” feature of QuickCam 9.x and above

  1. Insure that all audio streams are stopped
  2. Connect your QuickCam video device to initiate the cameras microphone
  3. Open “Windows Control Panel” and double click the “Logitech Camera Settings” icon
  4. Select the “Audio” tab
  5. Locate and uncheck the “AEC” option

After completing the above, please verify that the hardware acceleration slider for all Muv Audio Virtual Cable devices is set to full acceleration.


Adjusting Hardware Acceleration:

  1. Click on the Start Menu
  2. Then double-click on Control Panel
  3. If not in "Classic Mode", on the left, click Switch to classic view (This may or may not be needed depending on if this has been done previously. If the bar on the left says "Switch to Classic view" it is needed. If it says "Switch to category view" it is not.)
  4. Next, double-click on Sounds and Audio Devices
  5. Now, click on the Audio tab
  6. Change the default device to Muv Audio Virtual Cable 1
  7. Then click on the Advanced button below the audio device
  8. Now, click on the Performance tab
  9. Next to Hardware Acceleration make sure the slider bar is all the way to the right, which is labeled Full
  10. If it is not, drag it to the far right and click apply
  11. Restart your computer.

Following the steps above should resolve the issue with your recorded files being played in "slow-motion".  You will need to re-record the file after making these changes.

The steps in this article were obtained from the Logitech KB article 5271; please see this article for additional information.
