• Why the audio quality of Apple TV 4 film is so bad?

  I have my Apple TV (4th generation) hooked up to my receiver Pioneer Elite and the audio quality is very, very bad on all HD, its horrible movies. Everything is fine with my HDMI cable, receiver, or Apple TV. The volume is so low compared to the playback of a blu - ray movie or watch anything on television. When I watch a movie to iTunes HD on my Apple TV, I have to turn up the volume so much, but it does not increase the volume as it should. The audio is so different from a blu - ray movie, seems almost alive compared to watching a movie to iTunes on my Apple TV. Its really, really frustrating. Its almost unacceptable. Whats up, the poor audio quality? In most cases I pay more money for a movie to iTunes that the blu - ray of the same film. I expect the same or better quality audio.

  Sorry it's perfectly audible here, you do not have something to get lost with your installation or your equipment.

• CarPlay audio quality of the voice when it is connected through the USB port is poor vs Bluetooth on Pioneer AVH-4200NEX

  Hello!

  I recently installed a Pioneer AVH-4200NEX unit, I was super excited to improve my car with the support of CarPlay, and everything works great except for one thing.  When I connect my iPhone (6s +) to the unit via a USB cable and a standard phone call, the audio quality is very bad - hail, very downsampled, and metallic sounding compared to the use of Bluetooth via the unit to pioneer for the same phone call (I'm on LTE, using HD voice, although the quality difference is quite noticeable on the calls not HD and on the 4 G calls).  I looked for an answer to this question, but the best that I can find mention of limited USB bandwidth and try to juggle than the bandwidth for the rest of the CarPlay experience, although I don't buy not because audio via the iPhone connected with USB playback is just as clear that it is through Bluetooth.  So my question is: How can I submit a bug report Apple about this behavior and (b) do you have other CarPlay users also be known this recent problem on a unit of Pioneer NEX (AppRadio included)?  It would be great if this is a bug of Pioneer for which they can release a firmware update, I'm just worried that it is a codec problem specified by the CarPlay, so non repairable.

  Thank you!

  If CarPlay does not work as you expect, here's what you can check. After each step, try to use CarPlay again.

  1. Make sure that Siri is turned on.
  2. Restart your iPhone and your car. Depending on your car, you can see the CarPlay home screen when you turn it on. If you do not, look for the CarPlay logo on the screen of your car.
  3. If possible, connect your iPhone to a different USB port in your car.
  4. Try a different lightning to a USB cable. Make sure that the cable is certified.
  5. Update to the latest version of iOS.

• Audio Fadin incoming and outgoing, but the video quality remains high.

  Hello. I am regularly skyping someone, but the incoming audio signal began fade in and out and sometimes mute altogether. The video quality is very good and she can still hear and see me OK. The volume for Skype and everything else is wound up to the maximum. I tried skyping someone else and the problem was not present.

  I do not understand how the audio quality that I can fade, but the video quality does not change. I would have thought if they had problems of band bandwidth then the video would have refused and the Lady, I'm not talking would receive me in this good quality either.

  Is anyone know something about this problem and a possible solution?

  Thank you

  Hello. In the case where someone comes across it because they have the same or similar problem I found the solution. It turns out, somehow, that the volume of my microphone had been wound up to the maximum. Because Skype reduces the audio signal entering when you make noise, the person I was calling I couldn't hear because I was broadcasting involuntarily every tiny noise. This interrupts my incoming audio. For some reason I have the microphone picks up a ridiculous level of background noise. Only, I discovered this after a test of back to back with my mother's laptop. To stop the problem I just wrapped up my microphone volume down in audio on Skype settings until there no sign up tapping or other noises. So I send you not now sounds that would hurt my incoming audio. It also explains how the Lady I was calling could still hear me fine and the quality of the video never abandoned, but the audio signal coming at my end was.

• Windows 7 - audio system sometimes works and sometimes doesn't. Soundcard Question. Issue of the audio recording. Poor sound quality from the speakers.

  I connect on - the work of sound system very well.  Media player works fine.  The next time I log on - no sound system.  Everything is plugged, convenience store finds no problems, Media player goes through all the steps and looks that don't worry, still no sound.  I have download a fix for the VIA recommended by Dell Driver.  I did, and it still has the same problem.  I can close, reconnect, and then the sound will work.  Sometimes I have to close and log on twice in a row so he can launch.

  Can someone point me in the right direction to solve this problem?  I am working on a Dell Inspiron 546 AMD Athlon II x 2 215 2.70 GHz and 64-bit with 400 GB of RAM.  I installed Windows 7 but when I dug deeper into the service code for this machine which found at some point in time he had installed Vista.  This could be the same Vista to Windows 7 problem audio, everyone seems to have?  I bought this Staples announced new with Windows 7 as operating system.

  I did research on all forums and responses and am unable to check if I have a "sound card".  I'm not used with the terminology so even if I follow the Microsoft instructions to find the right place to check and see, I do not understand what I see when I'm there.  It is said: ATI high definition Audio Device and VIA High Definition Audio.  Is this to say that I have a sound card or I should get it a?  If I buy a sound card will it fix my audio problem?

  Even though I had my audio problem fixed, I was disappointed by the sound quality of the speakers on this new system up to date.  My speakers on my old computer (which lasted from Windows 98) were by far superior in sound quality.  I don't understand why they sound so crappy and barely louder, and when you show the to they have a rattle for them.  I tried plugging my old speakers on my new computer, but nothing happens.  My new speakers have a Plug and a USB port.  I don't know what is... why goal can not use my 'old'?

  Finally, I want to record my vinyl on discs and need a great sound system.  Any advice?

  I removed all the ATI Audio as suggested.  The result in the short term is that the audio quality is improved.  I no longer hear the "crackling" when the sound is turned on.  I'll answer more if the issue of audio (works) continues to be a problem because the fix.  If you don't hear from me, then please consider the problem solved and my thanks to you.

• Improvement of the sound quality/volume of the video

  I recorded some videos of a religious service, but the audio quality is quite poor.  It would be nice to find a way to turn 'up' so you can hear it without starting your speakers all the way up and blow when you change projects.

  Is there a way to tinker with sound quality? All the features that I found involve adding audio... not changing audio embedded.

  Quick help is greatly appreciated. I would like to have this video ready to ship tonight.

  Some audio features the most powerful, as I explain in my book is normalization and Gain Audio control.

  To access it, right click on an audio clip on the timeline, and then select Audio Gain.

  You don't say what version of the program that you use, but in all versions except the version 8, by clicking on the button to standardize will automatically increase the audio gain for the clip so it sound fuller and stronger. In version 8, this feature is not enabled, so you have to manually type in a number of gain.

  When you close this option button, you will see that the audio waveform for the clip is much more comprehensive. It should go 'wall' without being so strong that it overmodulates and distorts. You can try some Audio Gain settings until it looks about right. (Even better if you open the Audio Mixer Panel, under the menu drop-down window and look at the levels. "They should be full but not in red.)

  A lot more stuff like that in my books, available on Amazon.com and at the store Muvipix!

• Audio quality on Satellite C55-A-1

  Hello

  I'm considering buying a laptop model Toshiba C55, C55-A-1 to be precise.
  However I'm a bit read comments and one or two people were not satisfied with the audio quality of the machine.

  I was wondering if anyone here is familiar with the series C55 and can comment on audio quality and the quality of president of these laptops.

  How do they get to watch a move, or listen to music?
  They produce audio undistorted clear?
  are they strong enough (given the fact that I wear a hearing aid because I have a terrible hearing).

  I have a Toshiba laptop at the moment, I have had for nearly six years and feel that it may be time for an upgrade.
  My current model is a P300-16 t and has served me very well.

  I would appreciate any advice and answers to the questions I asked, I thank you for reading and for any help provided.

  > However I head a little read comments and one or two people were not satisfied with the audio quality of the machine.

  + One of the two people was unsatisfied +: well, I put t appreciate these opinions.
  It turns out that you can not compare this notebook with a costly high range support or Playbook. You must always consider the value of price-ration.

  This series of portable was equipped with common standard designed speakers and you shouldn't compare the sound for laptop computers equipped with speakers harman cardon.

  But the laptop is supported by some sound effects called DTS Sound controlled by software pre-installed. This software enhances the sound quality immensely.
  In many cases, people are not aware of such a software and don t use.

• W500 Bluetooth poor Audio quality

  Hi all

  I recently bought a Bose Soundlink speaker bluetooth and have paired with my ipod touch and w500. IPod Touch sounds good, but the audio through the speaker to come via the w500 looks like it's cut, especially at the fort-normal listening level. The soundlink both the w500 have installed bluetooth driver updates. Clipping occurs even when the main (and iTunes/Spotify) volume are at least 50% of power.

  My question is if there is a way to reduce the 'power' of the bluetooth signal so it does not cause the speaker to distort. Audio read by the speaker through 3.5 mm of the w500 sounds great even at high volume.

  Thanks for any response.

  Hello!

  It's not the cut, clipping occurs in the analog world.

  In the case of Thinkpad Bluetooth - only low bitrate audio is probably set up for A2DP. So you get a large number of artifacts of compression and bandwidth.

  The solution to install a third-party Bluetooth Stack instead of Lenovo drivers.

  I had the same problem with my speakers wireless X 220 and Creative D200. The audio quality has increased considerably with the BlueSoleil software, but I could still hear a few distortions bit.

  Then I tried to install Toshiba Bluetooth Stack, it requires a few changes to the .inf file but can be done.

  The sound quality is now close to perfection.

  I hope that helps! Let me know if you need details.

• Audio quality Sony RX100

  I own a HX30v, but the audio is so intestine makes videos virtually unusable. I think buying a RX100.

  Is the audio quality on the RX100 substantially improved over the HX30v? Is this a switch that I should do?

  Don

  I wouldn't assume that the HX30v has an audio volume control where it allows you to adjust the audio volume would?

  Other than that, you watch the video on the computer or camera? On the computer, it is generally much stronger than you think.

  Otherwise, who knows...

  I have not had the RX100, but I know by the other Cybershot, that the audio was good - but at the end of the day, it depends on the user. Maybe it still won't be enough for what you're looking for?

  If possible, see if a store has one that you can try, give it a try. Don't forget, it's going to be soft on the camera from the computer. Or try a few video samples of the RX100.

• Audio quality in Photo Story 3

  I use profiles customized Papa John's for Photo Story 3, it says the audio is supposed to be at 320 Kbps, but when the video is finally created the audio is very fixed, is it possible to improve the audio quality until it should be? I use it for videos from YouTube because it allows me to remove black borders and have the image full screen of the player, if it can not be helped, there there other video editors that allow to remove black borders?

  Thanks for any help :)

  I also tried to use mp3 files but had terrible audio results.

  Then I read the WMA or WAV files work best. I tried several WAV files and the sound is beautiful!

  Good luck.

• Bad audio quality 20 minutes on chat (Skype)

  After about 20 minutes on Skype, the audio quality degrades significantly, the peer has echo, I have various disturbing tones or my sound is like a Bedard.

  These effects report different partners on Skype, but only with me! Therefore, I propose that the fault must be on my PC.

  Hi Peter kaufmaqnn,.

  Follow the troubleshooting steps in this document Support of Skype.  You have other applications/programs running when you use Skype? Check your communication settings using the following steps. If it is set to do nothing, change to reduce the volume of other sounds of 80%.

  1. Right-click on the volume icon in the notification bar (usually lower right corner of your screen)
  2. Select the playback device
  3. Select the Communications tab
  4. If the activity of communications is nothing, try to change to the setting suggests above.
  5. Click apply
  6. Click OK

  You can also check to see if you get the same sound quality when you use a different headset or try your headphones on another computer.

  Let us know if that helps.

• View Feature Pack - RTAV: how to increase audio quality

  Hi, we test see 5.3 with feature pack installed. RTAV is really great, especially with the webcam. But the audio quality of the microphone is limited to 8 khz and there seems to be a strict limit.

  There is a VMware KB explaining how to increase the video, but not for audio quality. Is there a way to change the audio settings for RTAV? And if not, why this very low limit? We understand 8 kHz is just OK for Skype calls, but it could be better.

  PS: We use Windows client 2.3 and invited is Windows 7 x 64. Thank you!

  Hello

  Unfortunately at this time - you are right that the audio is limited to 8 kHz, mono.

  This is something, that we thought do adjustable - but until your post - we have had no feedback that we had to and so it remains at this since the original sampling rate.

  Would you be willing to explain your use case to better understand the needs and identify what kind of audio controls you would like to see.

  I can't promise we will be in work, nor provide a time scale, but given your comments will definitely help.

  Thank you very much

• Loss of audio quality when exporting first pro

  I have now had this happen with two different videos. I play the video in first pro and the sound is fine. I export video and lose the bulk of the quality of the audio. A project is a music session when I exported only get the main voice drums are not audible only a hum is done only if the bass drum usually would. On another project is a video thank you for a member of the family, and the sound is distorted after having been exported. The sound inside the session. Exported audio will be still work fine on my computer and my iphone 5S for as long as I'm wearing headphones, once I try to play the video through my iphone 5 s audio speakers is gone, noise as described above. My iphone can still play other tracks very well but the videos and audio exported from first Pro are distorted. Any advice on how I can export the video, so I won't lose the audio quality during playback of video on an iphone? I know this isn't my iphone speakers, they play other songs very well.

  Yes the dialogue is 100% out of phase, so if it is played on any single device both channels will cancel each other. To fix it, in the first timeline all defective audio and add the fill left audio effect. Then you re-export.

• How to increase the control limits for the Audio Volume?

  I have upgraded my PC base unit and no longer have the output of the Speaker Volume I had before. The audio output is more silent than before with the same speakers I used. I have moved all the sliders on the control panel of the Volume on their maximum position, but still can't get enough of output to the speakers. The important thing is for my use are 'Volume Control' and 'Wave', and these are set to the maximum. Now I have a motherboard with Intel D845GERG2 Intel i845GE chipset. The operating system is Windows XP Professional SP3, as previously. The sound card is SoundMAX Integrated Digital Audio with Legacy audio drivers. I checked using Device Manager drivers and hardware to work properly. The problem is software because I can achieve the required high speaker volume if I use VLC Media Player and set the volume to 200%. With Windows Media Player, set the volume to 100% is sufficient. I'm looking to increase range parameter on the control panel of Volume as a general solution. Can you advise if this is possible? I looked at a few ideas, these courses: edit files (.inf) SoundMAX driver. Modify the registry keys concerned. Use different audio drivers (none seem to be available for my hardware). Install the software to boost the audio output (VLC Media Player should be achieve this somehow). Install alternative (rollback) Microsoft drivers. Any advice would be much appreciated.

  Just an update of my efforts on this issue.

  I revisited the audio registry settings SoundMAX for HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\ \0005\Settings {4D36E96C-E325-11CE-BFC1-08002BE10318}. These are installed when you install the driver for SoundMAX Integrated Digital Audio. Changing these settings has already failed to get an increase of output audio volume. I have now found some settings of the value of these registry keys that have given me a satisfactory increase in the volume of the audio. In short, the cure for my situation was:

  The file source (wdm3516b_Cadenza.exe) driver available from the Download Center Intel is a self-extracting ZIP file. Unzip this file to a location convenient temporary store (C:\Temp)

  Use a text editor (Notepad) to edit the INF of the driver - in my case, it's "smwdmCH4.inf. Changes to this file cause the digital signature of the file to be invalid, but choose "Continue Anyway" to solve this problem during the installation of the driver. To increase the sound volume levels, the audio volume registry key value parameters that have been predefined 08 (hex) have been changed to 01 (hex). I suppose that this change dB levels produced by the SoundMAX Integrated Digital Audio.

  To install the new settings:

  Uninstall the SoundMAX Integrated Digital Audio hardware by using Device Manager.

  Restart the PC - this should give a "new hardware found" restart of the PC.

  Use Device Manager to reinstall the driver for SoundMAX Integrated Digital Audio. Do not use the automatic selections for this - run the installation process where you stored the INF driver edited file.

  Once installation is complete, a check on the properties of the device must indicate that the device is functioning properly.

  Use regedit to check that changes in the edited file driver INF appeared in the area of the Windows registry - in my case, it is HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\ {4D36E96C-E325-11CE-BFC1-08002BE10318} \0005\Settings.

  I will emphasize that it is NOT a recommended fix - it turns out that it worked for me. The usual caveats apply - save your original settings, or better yet, use software disk image to make a copy of your drive hard so that you go back to square one if she's going "pear-shaped" with adaptations that have been made.
