The Ploytec USB ASIO 2.8.45 driver claims to offer low-latency and high-quality audio performance on Windows computers using USB audio devices. The actual performance of the driver may vary depending on the hardware, software and settings used. Some factors that may affect the performance of the driver are:

  • The USB audio device itself, including its firmware, chipset, clock and converters.

  • The USB port and controller on the computer, including its speed, bandwidth and power.

  • The CPU and RAM of the computer, including their speed, load and availability.

  • The audio software and plugins used, including their compatibility, stability and efficiency.

  • The buffer size, sample rate, bit depth and channel configuration selected in the driver control panel.

  • The audio format, quality and content of the audio files played or recorded.

  • The background processes and services running on the computer, including their priority, interference and resource consumption.

Generally speaking, the lower the buffer size, the lower the latency, but also the higher the CPU load and the risk of dropouts or glitches. The higher the sample rate and bit depth, the higher the audio quality, but also the higher the data rate and the disk space required. The optimal settings for each user may depend on their personal preferences, needs and expectations.

Some users have reported positive experiences with the Ploytec USB ASIO 2.8.45 driver, praising its low-latency, high-quality and stable performance. Some users have also reported negative experiences with the driver, complaining about its high price, poor compatibility and buggy performance. The user reviews on various forums and websites may provide some insights into the performance of the driver in different scenarios and setups.


The Ploytec USB ASIO 2.8.45 driver is not a free software. It costs 59 Euros (about 69 US Dollars) for a single license. The license is valid for one computer and one USB audio device. If the user wants to use the driver on another computer or with another device, they need to buy another license or transfer their existing license. The license transfer process is not automatic and requires contacting Ploytec via email.

The Ploytec website offers a demo version of the driver for free download. The demo version has all the features of the full version, except that it produces a beep sound every 60 seconds. The demo version can be used for testing purposes before buying the full version.


The Ploytec USB ASIO 2.8.45 driver is a software that enables low-latency and high-quality audio playback and recording on Windows computers using USB audio devices. The driver has many features, supports many devices, claims to offer good performance, but also costs a significant amount of money. The driver may be suitable for some users who need a reliable and flexible solution for their USB audio needs, but it may not be worth it for others who have cheaper or better alternatives available. The best way to find out if the driver works for you is to try it yourself using the demo version.
