Is Audio Latency Important?
Firstly, if you are into audio producing, latency can be problematic. Gamers rely on positional audio, where latency is critical. Music lovers will have a bad listening experience if latency is not within specifications. Streamers who are dependent on broadcasting software like OBS (Open Broadcast Software) already must deal with streaming bandwidth, and they do not need to battle audio latency too. However, if you are not a heavy audio user, there is a good chance you will not notice the sometimes-small audio imperfections caused by latency. We will show you how to perform an audio latency test for Windows 10 and teach you how to improve audio latency. On the other hand, if there are serious latency issues, you will notice them regardless. How?
To audiophiles with a well-tuned ear, it often means troubleshooting trying the cause. In addition, what causes audio latency? The short answer is that it could be many things. Luckily, there is an excellent audio latency test for windows 10 acts as a starting point. In many (if not most) cases, it will not directly tell you how to improve audio latency. However, as you will soon see, any slight hint you can get is helpful. What does audio latency sound like, and can your ear hear it? Often it will be short dropouts of audio when it stops playing for a short amount of time (milliseconds or less). Moreover, it can also sound like clicks, pops, or other imperfections. To learn how to improve audio latency, you must find the cause.
What Causes Audio Latency?
An audio latency test for Windows 10 will show IF you have audio latency, but it will not show how to improve audio latency. More on this in a minute. Above all, we answered some of this in our “what does audio latency mean” section, but there can be many audio latency causes. Some, such as driver and OS updates, are apparent causes. For example, there can also be hidden causes of audio latency: Windows Power Settings, BIOS updates, overlapping sound devices, and countless other reasons. In addition, rogue audio latency problems are among the more complex computer issues to track down. You will need a systematic and patient approach to fixing audio latency problems, especially in Windows 10.
Obvious Causes of Audio Latency
We covered the understandable reasoning of what does audio latency mean. However, before we even do an audio latency test for Windows 10, cover the bases. For example, what causes audio latency? One of the biggest offenders is outdated software. Therefore, the first step in how to improve audio latency should certainly be to update everything. You really cannot continue to check audio latency issues if you do not have an entirely up-to-date system. Meanwhile, if you are unsure how to do some of the subsystem updates on your system, we will cover tools in our “essential software” section. However, always start with updating Windows, check for updated sound and video card drivers, and check your BIOS manufacturer updates. Also, update any software you use for audio, like production, streaming, or gaming software.
After you have exhausted software, drivers, and BIOS updates… what is next? Firstly, what causes audio latency? More than you think. For example, there could be hidden causes. It could certainly be your Windows Power selection, some hidden Windows setting like Core Parking, your Page File setup, and many other obscure reasons for latency. Likewise, as you begin to understand the complex question of, “what does audio latency mean?” you will start to question your sanity after a while. Each of the system changes we will cover in the “how to improve” section. Wait to see if there is an issue, repeat. In addition, the audio latency test for Windows 10 will be our first discovery step. We will then continue with exactly how to improve audio latency. Ready?
Audio Latency Test for Windows 10
To discover what causes audio latency, you need a reliable test. Firstly, the LatencyMon software is the go-to standard for testing on Windows 10. What does audio latency mean to you, though? For example, do you require high-end audio processing for music production? Meanwhile, maybe you need crystal-clear audio and 3D positioning for gaming? Or is a reliable continuous stream of audio for streaming essential? Finally, as you start to discover what causes audio latency, you might have to make decisions. Upgrade the cheap built-in soundcard on your motherboard with something like a Sound Blaster? Or is that small pop you hear in audio every few hours OK for casual use? We will show you the basic steps in improving audio latency (without buying new hardware) while leaving the remaining discovery to you.
How-To Use LatencyMon
What causes audio latency? Firstly, let us find out with an audio latency test for Windows 10. LatencyMon is your first step in how to Improve audio latency. For example, ask a producer, “What does audio latency mean?” and they have LatencyMon flashbacks. Likewise, LatencyMon is easy. Launch LatencyMon and click “START.” Secondly, do some everyday audio tasks. A good choice is a real-time frequency production software. Click “STOP” when finished. Start with the “PROCESSES” tab. Firstly, you want to look for hard page faults. Page faults mean Windows needs to read from the paging file instead of RAM. If things look OK here, check the “DRIVERS” tab. Interrupt, and Procedure Calls may also cause latency. Using this tool will give you a starting point. Use your frequency software in between test phases. It would be best if you began troubleshooting with system, drivers, or software that is causing hard page faults or interrupt procedure calls.
Do we know yet: what does audio latency mean? Above all, here is some essential software when troubleshooting latency. For example, you will notice several video card utilities listed here. In between audio tests with frequency software, keep checking. You would not think, but video card drivers often cause latency. Firstly, they usually contain their audio drivers to support the audio functions of your video card. Secondly, they often have bloatware (extra software in addition to the base driver). Another good test bed is a live streaming radio station. Most importantly, The list below is your essential software toolkit for troubleshooting latency.
- LatencyMon is for checking audio latency in Microsoft Windows.
- Avira AntiVir Low-Profile Virus and Malware Scanner.
- Display Driver Uninstaller will completely uninstall display drivers.
- NVCleanInstall installs Nvidia video card drivers without bloatware.
