If Sndvol or another application changes the volume level of the endpoint device, the client can receive notification of the change through the IAudioEndpointVolumeCallback interface. As explained in Audio Sessions, Sndvol is the system volume-control program. It displays volume controls for the audio-rendering endpoint devices in the system. How can I control the System Volume Setting of Windows 10? Which Libary I need? I am using Visual Basic 2015 and wanna programm a Windows Universal App with C#. The programm should be able to: Set Systemvolume to x% increase the Systemvolume by x. Decrease the Systemvolume by x. Get the current Systemvolume.

Adjusting the delay between the front and rear speakers is important when calibrating your system. Setting the delay too long may result in an echoed, unnatural surround field, or cause imaging shifts in the soundfield. However, adjusting the delay too short may result in a flat 2-dimensional sound field between the front and rear speakers.

The speed of sound in air is: 1100 ft/sec

1100 (ft/sec)*1(sec/10^3ms) = 1.1 ft

Every 1 ms of delay added corresponds to 1.1 ft of increased distance of your rear speakers relative to your listening position.

For Example: Setting the rear delay to 25ms would result equivalently placing the surround speakers 27.5 ft away from your listening position!

As a rule of thumb:

1. If your surround speakers are located close to your listening position, adjust the rear delay short (5-15ms).
2. If your surround speakers are located far away from your listening position (20-30ft), adjust the rear delay long (15-35ms).

Note : It is important to set the delay correctly so that proper time synchronization occurs.

Audio Level Adjustments

Level calibration between all of your speakers in a 5.1 system is one of the most important adjustable parameters. Many people tend to boost the rear speaker levels too high relative to the fronts and center channels. This sometimes tends to overemphasis the rear channels resulting in an unnatural surround field that is easily localized by the ear. Over emphasizing a particular channel sound level will diminish the balance in the system. Doing so undermines what the recording engineering intended the mix to sound like for the movie and/or music CD.

I recommend the following procedure for proper level calibration of your 5.1 Surround System:

1. Select a common listening position.
2. Adjust the master volume of your Receiver/Preamp to a common listening level you are accustomed to (say 75dB).
3. Initiate the Receiver/Preamp test tone.
4. Allow the test tone to sweep each speaker in your system.
5. Adjust the volume levels of each channel until they sound similar in volume. It is preferable to use an SPL meter (C-weighing, Slow Response) for greater accuracy.

This is the first step in calibrating the sound levels of your 5.1 system. Please remember that these levels will need to be tweaked depending on the source recording and/or surround scheme.

For example: Some recordings may boost the rear channels 1-3db higher than nominal due to poor mixing methods or deliberate wow factor. If the rear levels sound too loud when watching a movie or listening to a 5.1/6.1/7.1 audio mix, simply lower them until they sound balanced relative to the front and center channels.

I recommend acquiring a multi-channel set-up disc such as the one from Avia, Sound & Vision, or DTS. It will help you calibrate your listening levels of your speakers and subwoofer as it sweeps frequencies 20Hz to 20KHz for all channels.

If you don't trust your ears, you may wish to purchase a Radio Shack SPL meter. When operating the test tone of your Receiver/Preamp, calibrate the volume levels within 1 dB relative to each channel. Hold the unit so that the microphone is pointed at the ceiling and position the microphone as closely to ear level as possible (at the sweet spot listening position) when running this test.

Note: Rome 2 total war mods. Make sure you set the scale to 'C-Weighted' on the SPL meter as this closely matches a flat frequency response curve throughout the audible band. The early AVIA test discs used to recommend the 'fast' setting on the SPL meter but we've found it easier to get more consistent results using the 'slow' setting which allows easier readability.

Technical Advances Update: Most receivers/processors built since 2003-2004 enable you to merely configure the distance from each speaker to the listening position. The mathematical delay calculations are then performed by the receiver or pre-processor, thus saving you a lot of headache and time. be sure to calculate distances to a singular point, the sweet spot, even though you may have listening positions throughout the listening room.

One of the things I often notice when listening to various surround sound systems is a disparity in either the subwoofer levels or the levels of the center or surround sound speakers. The problem with a misconfigured system is that you miss out on hearing at least the balance intended by the rerecording engineer who mixed the soundtrack (in the case of a film) or the mastering engineer (in the case of a multichannel music mix). That’s not to say that calibrating and getting the correct levels is all there is to attaining perfect surround sound, but it’s certainly a big part of the picture.

So the big question is: How do you calibrate the levels for each channel in order to get an accurate representation of the levels in each channel as intended at the listens position? As it turns out, the process is very straightforward and easy to do accurately.

Manually: Calibrate Surround Sound Levels with an SPL Meter

You can use a simple $35 SPL meter to calibrate surround sound levels in each channel of your home theater system. To do this, set the appropriate crossover for your speakers and then follow these basic steps:

• Go into the System Setup menu of your AV receiver
• Navigate to the speaker setup submenu
• Select channel level or speaker level (in some receivers you need to enable the test tone)
• Select the Left speaker
• Using an SPL meter, set it to Slow response and C-weighting and raise the level of the receiver to 75 dB SPL
• Using the Setup menu of e AV receiver, change the output channel and work your way around each channel of your 5.1 or 7.1 speaker system.

Special Note on Subwoofer Calibration

A lot of subwoofers (perhaps “most” subwoofers would be more accurate) cannot be calibrated perfectly with the test noise pattern present in AV receivers. As a result, don’t worry too much if you end up changing the level of the subwoofer to taste. After you do this, be sure to re-run the levels to ensure you are still even across all speaker channels.

Automatically: Calibrate Surround Sound Levels with an Auto-Setup Microphone

Each AV receiver that includes automatic room EQ and speaker setup to calibrate surround sound levels is different, but all of them include the option to use the system to setup levels only. I actually recommend this with one exception. Most automatic speaker calibration systems cannot accurately set either the speaker size, the crossover for the subwoofer or the subwoofer level. That means that if you do use the system to set up your speaker levels, be aware that you will need to go back and likely change your main speakers to “Small”, raise the subwoofer crossover level to 80Hz and also tweak the final subwoofer volume level.

Even with these quirks, using an automatic speaker level system to calibrate surround sound levels and set up your room is beneficial if you absolutely don’t have the means (or an SPL meter) to calibrate it manually. Given the choice, however, I always ptr the manual method since it means that I will understand each aspect of how my home theater is operating.
