Everything about Obsid Pro.

Simultaneous headphone and speaker audio routing

Windows has a fundamental limitation that most users never question. When you connect headphones to a Windows PC, the operating system routes all audio exclusively to that device. Speakers go silent. When you switch back to speakers, headphones go quiet. This is not a hardware constraint. Your audio hardware is perfectly capable of playing audio through multiple outputs at once. It is a software decision built into how Windows handles audio devices by default.

Obsid Pro removes this limitation entirely. Using a virtual audio cable that installs automatically during setup, Obsid Pro intercepts your system audio before it reaches any output device and routes it simultaneously to every device you select. You can run headphones and speakers together, or any combination of output devices your system supports. There is no limit on the number of simultaneous outputs.

The reason this combination sounds better than either device alone comes down to physics. Speakers move air. When bass frequencies play through a speaker, you feel them in your chest and through the floor. Headphones cannot replicate that physical sensation no matter how good they are. On the other hand, headphones sit millimetres from your ears and deliver spatial detail, instrument separation, and high frequency clarity that open-air speakers struggle to match at any price point. Running both simultaneously means you get the physical presence of speakers and the precision of headphones at the same time. This is why cinema sound systems use a combination of subwoofers and precision speakers rather than a single type of driver.

Obsid Pro is the only Windows application that makes this setup accessible without manual driver configuration, command line tools, or third party audio mixers. You select your devices inside the app, and it works.

Unlimited device routing

Obsid Pro supports routing audio to an unlimited number of output devices simultaneously. This is not a feature that requires a higher tier plan. Every subscriber can add as many output devices as their system supports. Whether you want audio on two devices, four devices, or every speaker and headphone connected to your PC at once, Obsid Pro handles it without any additional configuration.

This makes Obsid Pro useful beyond the standard headphone and speaker combination. Home theatre setups with multiple speaker zones, studio monitoring setups where you want to audition a mix on multiple reference devices simultaneously, and gaming setups where audio goes to both a headset and desktop speakers are all supported out of the box.

10-band parametric equalizer

The equalizer in Obsid Pro gives you precise control over ten frequency bands spanning the full audible spectrum from 32 Hz to 16 kHz. Each band has an independent gain control and a Q factor that determines how wide or narrow the frequency adjustment is. This is a parametric equalizer, which means you are not limited to fixed-width adjustments like a graphic equalizer. You can make surgical corrections to a specific frequency or broad sweeping adjustments across a range.

The included presets cover the most common listening scenarios. The Cinema preset is tuned for film and narrative content with elevated low frequencies and a slightly rolled off high end, matching how cinema sound mixes are intended to be heard. The Music preset optimises for stereo music playback with a balanced frequency response that works well across most genres. Additional presets are available and new ones are added with each update.

The equalizer applies to all routed audio in real time. Changes take effect immediately without any audible artifacts or interruption to playback. You can switch between presets while audio is playing and compare the difference instantly.

Import EQ settings from any image

Obsid Pro is the first audio application to support importing equalizer settings directly from a screenshot or photograph of any EQ curve. If you have a preferred EQ profile in another application, a recommended EQ curve from a headphone review, or a tuning shared by another user as an image, you can take a screenshot and import it directly into Obsid Pro. The application reads the visual curve and recreates it as a parametric EQ profile.

This works with any number of bands and any EQ software. It does not matter whether the source image is from a five band graphic equalizer, a thirty band professional equalizer, or a parametric EQ from a different application entirely. Obsid Pro analyses the curve shape and maps it to its own ten band parametric engine as accurately as possible.

This feature solves a problem that has existed in audio software for as long as equalizers have been a standard tool. EQ settings are not portable between applications. Every software uses a different format. Obsid Pro sidesteps the format problem entirely by reading the visual representation that every equalizer produces, making any EQ profile from any source immediately usable.

Spatial audio and custom HRIR

Spatial audio in Obsid Pro creates a three dimensional sound field that makes audio feel like it exists in the space around you rather than inside your head. The spatial audio engine uses Head Related Impulse Response processing, which simulates how sound reaches your ears from different directions based on the physical shape of the human head and ears. When implemented correctly, HRIR processing produces a convincing sense of direction and distance that standard stereo playback cannot achieve.

Obsid Pro ships with a built in HRIR profile that works well for most listeners. For Pro Plus subscribers, custom HRIR file upload allows you to replace the built in profile with a file measured specifically for your own head and ear geometry. Personal HRIR measurements can be taken with specialist equipment or sourced from acoustic measurement services, and the resulting file produces spatial audio that is personalised to how you specifically perceive directional sound. The difference between a generic HRIR and a personalised one is significant for serious listeners.

Room calibration works alongside spatial audio by analysing the acoustic properties of your physical listening environment and adjusting the output accordingly. Hard floors, room dimensions, speaker placement, and soft furnishings all affect how sound reaches your ears. Room calibration accounts for these variables so the audio you hear is optimised for your specific space rather than a generic default.

Setup and installation

Obsid Pro is designed to be set up in under five minutes. The installer handles everything automatically including the virtual audio driver installation. You do not need to install drivers manually, configure audio settings through the registry, or use any command line tools. Download the installer, run it, and complete the setup wizard.

The only manual step is setting Obsid Pro Virtual Cable as your default audio output in Windows Sound Settings. This tells Windows to send all system audio through Obsid Pro before it reaches your physical devices. Once this is set, audio routing to all your selected devices begins automatically every time you start your PC.

Obsid Pro runs as a background service with audio priority, meaning it continues working whether the app window is open or minimised to the system tray. The application starts automatically with Windows so your audio setup is always active without any manual intervention.

Platform support and what is coming next

Obsid Pro currently runs on Windows 10 and Windows 11. Version 1.0 is the initial release and includes all core features. macOS support is in development and will be released as a future update. Android support for mobile audio routing is also planned for a later version.

Obsid Pro is available in two subscription tiers. Obsid Pro at $10 per month includes a three day free trial, one user account, and full access to all core features including simultaneous audio routing, the parametric equalizer, EQ import from image, spatial audio, room calibration, and all audio presets. Obsid Pro Plus at $25 per month supports up to four user accounts, adds custom HRIR file upload, advanced settings, all application themes including exclusive easter egg themes, and every feature added in future updates at no additional cost.

The feature set will continue to expand. Every Pro Plus subscriber receives every new feature as it ships without paying anything additional. The roadmap includes expanded spatial audio profiles, additional EQ preset libraries, deeper integration with Windows audio APIs, and the cross platform releases mentioned above.
