Clearsound club presents a new high-end audio player with support for PCM and DSD formats,

fast scanning of music libraries and traditionally exceptional sound quality.


Some distinctive features of the player:

– Automatic adjustment at every start

– Checking the connected audio interfaces

 Preparing data for playback

 Playback at one sampling rate

 Truly seamless playback

 Native executable code

 Kernel in assembler

 Correct priorities of the created processes

 The minimum number of processes

 Optimal route for data movement

 Output only through ASIO and WASAPI Exclusive

 Graphical interface without DirectX

 Refusal to use tags

 Super-fast scanning of music libraries


Automatic configuration every time you start.

 A unique feature, never seen in any other player.

Immediately after starting the player, the system is checked for compliance with the minimum requirements. If the conditions are not met, the player is closed.

Next comes the check if the DAC selected in the previous session is active and its parameters are compared with those saved earlier. If the DAC has a quick indication of modes, you can observe how the sample rates and pcm / dsd modes are tested. If the DAC is not active or its parameters have changed, a window is displayed with all the DACs available in the system, indicating the supported modes and sampling rates based on the test results for each of them.

After selecting the DAC, if provided, a window for setting various parameters of the player is displayed.

The next step is to configure the player in accordance with the system parameters and the selected DAC, including the reservation of certain memory areas, buffer sizes, priorities of the initiated processes, etc.

It is assumed that the OS is configured by default and no “optimization” programs are applied.


Preparing data for playback.

During playback, the read data is directed to a preliminary memory buffer. The double buffering method is used - when playing data from buffer 1, the next piece of data is written to buffer 2, then they are swapped. Since the data is in the dynamic random access memory for several cycles of its update, at this stage any possible interference and artifacts that arise when reading and transmitting data from the storage location to the main memory are completely eliminated. This means that neither the type of storage device (HDD, SSD, etc.), nor transmission lines (cables, wires, connectors, wireless links, etc.), nor intermediate devices (routers, switches, access points, etc.) cannot affect the sound in any way.


Native executable code.

The player's executable code is native to Windows. The player does not use DirectX, OpenGL, .NET Framework, etc. This ensures full compatibility with different versions of Windows, although it imposes some restrictions on the player's functionality, however, secondary, not related to high-quality playback of audio content.

The core of the player is written in assembly language. This allows you to fully determine and control the path of the audio stream through the intermediate buffers and the central processor. A similar approach is practiced when creating professional packages for working with audio content.


Super-fast scanning of music libraries

For scanning drives in order to create libraries, an original very light and fast algorithm is used. Scanning is performed only when the player is started and after opening it does not affect the sound in any way.

Another original feature of the formation of libraries is the sorting of albums in accordance with the structure of the catalogs on the disk.

Thank you for the focus!



- Take it playback is at the file sample rate

- what's the maximum DSD rate?

- plays over network? 

- prices?

- different versions for WASAPI, Asio, fair enough, what's the OS support? I'd guess no Linux or MacOs, which versions for Windows?

- any library size limitation?

1. The player always plays the file at the sampling rate. I meant that you can only open files with the same sample rate at the same time. Sampling rates from 44.1 kHz to 768 kHz are currently supported.

2. In the current version up to DSD512 - 22 579,2 kHz

3. If a network drive is mounted in the system and has a letter assigned to it

4. 150 Euro

5. The evaluation version works with ASIO, including in the Native DSD mode. There are also versions for DoP mode and only for PCM. The WASAPI Exlusive version is available on request. Linux in MacOS is not interesting to me.

6. Libraries are not limited in size. At one customer, the player easily and quickly scanned 4 HDD of 2 GB each. Roon on this library just froze.

All new albums will be shown after restarting the player. I can add a command for manual update.

The player does not have any built-in network protocols, it will see only those drives that Windows Explorer sees.
