If you activate both sets of input and output channels, you will notice that the 24-bit setting in the Sample Depth column is grayed out and the “Maximum sample rate” is shown as 48000 Hz.

NOTE: Whenever S/PDIF Input is selected as an Active Port, the Audiophile is expecting a digital signal at that port and to lock to the sample rate of that signal. When S/PDIF Input is selected and there is no signal present at the S/PDIF Input port, or the S/PDIF signal is not recognized or invalid, the Audiophile USB will not operate properly. Most likely, you will hear audio from the Audiophile, but it will be running at an odd sample rate and sound like it is playing at the wrong speed.

DD/DTS Pass-Thru:Just below the Sample Depth column, you will see a checkbox labeled,“DD/DTS Pass-Thru.” If you are using a Software DVD player and wish to send encoded multi-channel audio such as Dolby Digital or DTS to the Audiophile USB’s S/PDIF output port, then check this box. If you are only sending stereo audio (standard PCM—not encoded surround) to the S/PDIF output port during normal operation, then leave this box unchecked.

If you have this box checked, you can still send stereo digital audio to the S/PDIF port without any problems. However, you will notice that when the DD/DTS Pass-Thru box is checked, ONLY the S/PDIF port is active in the Active Ports column. Unchecking the DD/DTS Pass-Thru box will restore the port selection to the previous configuration.

Latency: Driver “Latency” can be selected from a range of values shown in a drop-down list located just below the “Maximum Sample Rate.” The default setting when the Audiophile is first installed is “Very High.” Because slower computer systems require larger sample buffers to avoid dropouts in the audio stream, a higher latency value is often necessary.

How low you will able to set the Latency will depend on several factors, such as your system’s performance and the performance of the music program itself. To test your system for lower Latency, try the “very low” setting first (as shown in the previous screenshot), and if your system stutters or performance falters, try the next higher setting until the system performance stabilizes. Once you are satisfied with any of the control panel settings, click OK to close the Audiophile USB Control Panel.

Version Numbers: The lower left corner the Audiophile USB Control Panel page displays the ASIO Driver Version, USB Driver Version, and the Firmware Version numbers currently in use. This is useful when checking for driver updates on the M-Audio website, or in the event that you need to call tech support and give them your system information.

Audiophile specifications

The M-Audio Audiophile is a renowned audio interface that has made a significant impact in the world of digital audio production. Designed primarily for musicians, producers, and audio engineers, it combines high-quality sound with user-friendly features, making it a popular choice for both home studios and professional setups.

One of the standout features of the M-Audio Audiophile is its high-resolution audio capability. It supports audio resolutions up to 24-bit/192 kHz, which ensures that recordings and playback are crystal clear and richly detailed. This high fidelity is crucial for critical listening environments where audio quality is paramount.

The Audiophile utilizes advanced A/D and D/A converters, which contribute to its superior audio performance. These converters are responsible for translating the analog signals into digital data, and vice versa. With M-Audio's commitment to quality, users can expect minimal latency and optimal dynamic range, making it ideal for real-time audio processing and monitoring.

Additionally, the M-Audio Audiophile features a robust set of inputs and outputs. It typically includes both balanced 1/4-inch TRS outputs and unbalanced RCA outputs, allowing flexibility in connectivity with various studio gears. The interface often has MIDI input and output ports, enabling users to connect MIDI devices easily, which is a significant advantage for electronic musicians and those working with MIDI-based software.

One of the key technologies integrated into the M-Audio Audiophile is its ASIO drivers. ASIO (Audio Stream Input/Output) provides a direct pathway between the audio hardware and software applications, greatly reducing the latency issues that can occur with traditional drivers. This ensures that musicians can play and record in real time without noticeable delays, making the creative process smoother and more enjoyable.

The compact and sturdy design of the Audiophile makes it suitable for mobile setups, while its straightforward interface allows users to get started quickly without the need for an extensive learning curve. The product is typically compatible with a wide range of digital audio workstations (DAWs), further enhancing its versatility.

As a reliable entry-level audio interface, the M-Audio Audiophile not only delivers exceptional audio quality but also provides the essential features required for modern music production. Its combination of high-resolution audio, MIDI connectivity, and user-friendly design makes it an excellent choice for anyone looking to elevate their audio production experience. Whether used for recording, mixing, or mastering, the M-Audio Audiophile continues to be a trusted companion for audio enthusiasts around the globe.
