Optimizing High-Resolution Audio: 24/96 24/192 to Receiver Without Downsampling

Introduction

High-resolution audio (24/96 or 24/192) offers unmatched audio quality but requires a specific setup to be transmitted without downsampling. This guide will walk you through the steps necessary to ensure that 24/96 or 24/192 audio is output from your Windows PC to your receiver in its native form, maintaining the highest possible audio fidelity.

1. Check Your Hardware

Ensuring your hardware is compatible with high-resolution audio is the first step.

1.1 Audio Interface or Sound Card

- **Compatibility**: Ensure your audio interface or sound card supports 24/96 or 24/192 high-resolution audio output.
- **Selection**: Look for devices that support this format and are known for their audio quality.

1.2 AV Receiver or DAC

- **Compatibility**: Verify that your AV receiver or Digital Audio Converter (DAC) can handle 24/96 or 24/192 audio formats.
- **Selection**: Choose a receiver or DAC that can accurately process these formats, ensuring the best possible sound quality.

2. Use the Right Connection

Selecting the appropriate connection between your Windows PC and receiver is crucial for maintaining audio quality.

2.1 USB Connection

- **External DAC**: Use a USB connection to connect an external Digital Analog Converters (DAC). Many high-quality DACs support 24/96 or 24/192 over USB, ensuring a clean audio signal. - **Connection**: Ensure the DAC is properly connected and configured to output the highest resolution available.

2.2 HDMI Connection

- **HDMI Output**: Connect directly to the receiver using an HDMI output from your PC, which supports high-resolution audio formats. Ensure both devices are set to the correct audio format in the HDMI settings.

3. Set Up Windows Audio Settings

Properly configuring the audio settings in Windows is essential for achieving high-resolution audio output.

3.1 Open Sound Settings

1. Right-click on the speaker icon in the taskbar and select **Sounds**.
2. Go to the **Playback** tab.
3. Select your output device, e.g., your DAC or receiver, and click **Properties**.

3.2 Configure Sample Rate

- In the **Properties** window, go to the **Advanced** tab. - Under **Default Format**, select the highest sample rate (24 bit 192 kHz) supported by your receiver. - Uncheck the option for **Click**. - Apply, then click OK.

4. Use a High-Quality Media Player

Choosing the right media player is key to avoiding any downsampling during playback.

4.1 Foobar2000

- A highly customizable player that can output audio directly to your device. - Supports ASIO and WASAPI output for direct playback, ensuring bit-perfect audio.

4.2 JRiver Media Center

- Supports various high-resolution formats and offers ASIO/WASAPI output for direct playback. - Ensures high-quality audio by bypassing the Windows audio mixer.

4.3 VLC Media Player

- Can be configured to output high-resolution audio. - Adjust settings to bypass the audio mixer for clean audio output.

5. Set Output Settings in the Media Player

Configuring your media player correctly ensures that the audio output is at the native format of your files.

5.1 WASAPI or ASIO Output

- Select **WASAPI Event Style** or **ASIO** if your audio device supports it. This allows for bit-perfect playback, avoiding any resampling by the operating system. - Ensure the player is set to output audio at the native format of your files (24/96 or 24/192).

6. Test the Setup

Verifying the setup is crucial to ensure that the audio is being transmitted in its highest resolution.

6.1 Play a High-Resolution Audio File

- Play a high-resolution audio file and check if the receiver is displaying the correct format on its screen or via an on-screen status indicator. - Verify that the audio is being received without any loss of quality.

Additional Tips

- **Drivers**: Ensure that you have the latest drivers for your audio interface or sound card as they may include optimizations for high-resolution audio. - **Disable Sound Enhancements**: In the audio properties, disable any sound enhancements or effects to ensure a clean signal. - **Audio Device Profiling**: Some software allows you to create profiles for different audio devices, making it easier to switch between different setups without manual configuration. By following these steps, you should be able to output high-resolution audio from your Windows PC to your receiver without downsampling, ensuring the very best audio quality possible.
