HD Voice: A Little Gem in TeamViewer 10

Sometimes, some great work by people such as software engineers can end up with barely a mention in the marketing materials or on the marketing department’s cutting room floor altogether. This can happen for any number of reasons, but when it does, such work usually takes the form of features and enhancements that exist as little gems for people to discover. On TeamViewer’s product page for TeamViewer 10, one of the features listed is performance optimizations, and within that description it very simply mentions “HD voice transmission quality.” In that little phrase there are hidden a lot of great ideas, hard work, and some pretty amazing results. Let’s take a closer look at this little gem.

VoIP: Can You Hear Me Now?

Over the years, the Voice over Internet Protocol (most often pronounced as a single word, voyp) has undergone a lot of advancement. Its roots go all the way back to network voice protocols developed as part of ARPANET in the early 1970s. The first public domain VoIP application didn’t actually appear until 1991, and it wasn’t until around 2004 before commercial VoIP service providers began offering widely available telephony services that use broadband Internet instead of traditional public switched telephone networks for voice communications.

From its inception, VoIP has been considered a very attractive alternative with tremendous potential. So much so in fact that by 1996, U.S. telecommunications companies had petitioned the United States Congress to ban Internet phone technology. Fortunately, that didn’t quite work out for them.

The Advantages of VoIP

The potential cost savings over traditional phone services are substantial, and even the smallest companies can routinely communicate with partners and clients around the world in a way that was previously only affordable and practical for large corporations. VoIP also offers tremendous flexibility in terms of communicating using a variety of different devices across various networks. Someone on his desktop PC at home can have a conference call with colleagues around the world using any number of different computers and mobile devices with a multitude of different hardware configurations and operating systems. All they need is compatible software and an Internet connection. However, one of the bigger challenges has been to improve overall voice quality, and TeamViewer 10 provides exactly that.

High Definition Voice Offers Noticeable Improvements

In TeamViewer 10, audio quality has been noticeably improved by increasing bitrate and reducing latency. In addition, a highly versatile codec ensures unmatched results for interactive speech over the Internet. The results are that a person’s voice sounds more natural and closer. No configuration is necessary. Automatic adjustments to options such the noise gate ensure that optimum settings are in place for the best possible conversation with reduced background noise.

With HD voice, conversations are more fluid as well. The focus automatically shifts to the content of the discussion as opposed to merely trying to communicate. A good comparison would be watching a movie on a VHS tape compared to a film on Blu-ray. When VHS first came out, it was pretty good; however by comparison, the poor picture quality of VHS is now just a distraction.

Other Factors That Influence Quality

HD voice doesn’t mean that audio quality is guaranteed to always be perfect though. It requires certain prerequisites in terms of bandwidth and the overall quality of participants’ Internet connections. The quality of the hardware used by discussion participants is also an important factor, and investing in higher quality microphones and headsets can make a substantial difference. All things being equal though, HD voice will still provide better overall audio quality then standard VoIP with the same Internet connection and hardware configuration.

To test TeamViewer’s high-definition voice quality for yourself, just go to teamviewer.com und download TeamViewer 10. Finding someone with whom to talk is easy too because the full version of the software is freely available for download.

    I’m using teamviewer to do some home recording into a non-profit radio station. I was hoping for studio quality audio, but I’m not getting that. Even with TV10 it isn’t studio clean. Any suggestions?

      Hello James,

      Thank you for your message. In TeamViewer 10, audio quality has been noticeably improved. Please note, however, that audio quality depends also on the internet connection. If the internet connection is slow it affects audio quality. If you would like to have more detailed information on this I would recommend you to contact our Support Department: http://bit.ly/1xzZVAt

      If you have any additional questions, please feel free to contact us at any time.

    James, I agree. The audio quality is not clean. Id like to use TV10 for controlling an unattended remote radio communication station and I need to be able to hear the radio channel noise. The DSP noise reduction in TV10 is too aggressive at any available user setting and fills the audio channel with boiling-watery background noise and digital artifacts. I would like to see an option to shut off TV10’s noise reduction altogether. The other thing I would like to see is a way to un-mute the remote computer’s mic input, as there is no one at my remote site to give “permission” by clicking the un-mute button on the remote screen. There should be an option to allow that control to appear on the Voip tab instead of being grayed-out.

      Hello Paul,

      Thank you for your message and for your feedback on TeamViewer’s audio quality. I have forwarded your feedback internally.

      Unmuting the remote computer’s microphone isn’t possible due to privacy and security reasons. Only the user of the remote computer has the right to decide whether or not he/she wants to unmute the microphone. I have therefore forwarded also your feedback on this feature internally. Please note that we cannot promise if and when the option for unmuting the remote computer’s microphone will be implemented.

      If you have any further questions, please do not hesitate to contact us at any time.

      Hello Del,
      Thank you for your message. What happens when you try to unmute the microphone? Do you get any error message? Does this happen in a remote control session or in a meeting?

    A little gem, but not working. Is there a suite of audio tests and manuals available, similar to the Skype Echo Service?

      Hello Alexander,

      Thank you for your message. If you experience any issues with audio I would recommend you to contact directly our Support Department: http://bit.ly/1xzZVAt They will gladly help you further.

      At the moment we don’t have a suite for testing audio. I have therefore forwarded your suggestion internally. Such ideas are always welcome, although I cannot promise when or if this feature will be implemented. For any questions on our product do not hesitate to contact us at any time.

    Every single meeting we have conducted we have quite unprofessionally go through with attendees and walk them through “unmute” the microphone.

    It sets a wrong momentum to a start of a meeting.

    I cannot see a privacy concern here, the person has gone into a meeting. The equivalent would be phoning someone and then having to unmute the micrphone on the phone each and every time.

    A middle ground would be to Message Box “allow Microphone Yes/No”.

    This is meeting mode only, when an attendee joins in.
