C3 AI-powered Gaming Dac Amp Co-Creation Program

As many of you know, Fosi Audio has always been a Hi-Fi brand. But over the years, we’ve been asking ourselves a simple question: How can Hi-Fi genuinely help gamers?

Earlier this year, we introduced K7, our first step into gaming audio, and the feedback from the market has been incredibly encouraging. Building on that experience, we’re now preparing to launch our next product in early next year: C3 — an AI-powered Gaming DAC & Amp

Unlike traditional gaming sound cards that rely on fixed EQ boosts, C3 uses AI models to recognize key in-game sounds, such as footsteps, gunfire, reloads, and directional cues, and dynamically enhance what truly matters, while reducing irrelevant or distracting noise. This isn’t about simply making certain frequencies louder. It’s about understanding which sounds are important in each moment of gameplay.

To achieve the best possible performance before launch on Kickstarter, we’d like to take this a step further with your help.

We’re inviting players to join a real-world audio co-creation program for C3, where real gameplay recordings will be used to help train and refine our AI models.

Below is a short demo showing C3’s current performance. In this clip, AI enhancement is applied only to footsteps, while all other sounds remain unchanged. (Before 0:50, it’s the original audio. After 0:50, the same gameplay is enhanced by C3.)

👉 Please watch the video:

What participants can get:​

🎁 Rewards​

  • 20 participants randomly selected for early Beta access
  • All participants receive 30% Kickstarter discount once C3 launches

📥 How to Participate​

To join the giveaway pool, simply leave a comment in this thread describing:
  • What games you usually play
  • What audio problems or pain points you experience in those games
  • What you wish a gaming DAC or sound card could help improve
  • Your current audio setup (headphones / IEMs / DAC / amp, etc.)
  • A short paragraph is enough.

⭐ Bonus (Optional)​

If you’re willing to upload gameplay audio or video recordings that we can use to help train C3’s AI models, you’ll receive additional chances to be selected. How to record:
1. Download audacity here: https://drive.google.com/file/d/1ChmjE-Ax4QzL0lBWwPgZuJdsdIJC9Hwh/view?usp=sharing
2. Record gameplay audio following the tutorial: https://docs.google.com/document/d/...ouid=118158918829769868032&rtpof=true&sd=true
3. Upload to YouTube (Public or Unlisted)
4. Comment with YTB link

💬 From the team​

Our goal is not to create an AI that only works in ideal conditions.

We want C3 to perform reliably in real matches, real rooms, and real gameplay situations.
Your participation directly helps shape how C3 — and future products — will sound.

Thank you for contributing to this program.
We’ll be monitoring the thread and responding along the way.

Hello friends.
You guys are a real idea factory!
This time, I want to team up with my son, who's a true expert in this field, so we'll both contribute our audio and gaming knowledge.

Game Title
Battlefield™ 6

Critical Audio Issues
Audio from multiple locations

What you want to improve
Clearly identify the source of each sound

Your audio setup and usage scenario

PS5 - DENON - X3800H - SAMSUNG Q990D - FOSI AUDIO K7 -PS5 CONTROLLER AUDIO - GAMING HEADSET

In this first step, we'll record external audio from a video capture card with audio extraction.

Hi
Thank you for your response. Do you think this is a technology that is genuinely helpful for gamers?

Regarding the point you mentioned, I’d like to understand it in more detail:


“Critical Audio Issues
Audio from multiple locations
What you want to improve
Clearly identify the source of each sound”

----could you give some examples of the types of sounds you aim to identify (such as footsteps, jumping sounds, clothing movement, etc.)?

Haha! By the way, I also noticed the K7 among your devices — this product was actually developed by me.

I’d love to hear about your experience using it and any areas you think could be improved.

Wishing you a Merry Christmas! 🎄
 
Since the audio signals originate from different locations within the game, it can sometimes be difficult to pinpoint their source.

Perhaps reprocessing the original audio signal could enhance certain frequency ranges or highlight specific details.

I'm not sure if the C3 allows signal processing before it reaches the audio system, for example, if you're using HDMI between the game source and the monitor/speakers/gaming headphones.

Congratulations on the K7's design. While you didn't manage it yourself, it's one of Fosi Audio's most beautiful and, above all, functional designs. Having physical controls is a practical advantage for everyday use.

The K7 is excellent; I'm sure gamers have been impressed by its quality.

Just a suggestion for improvement: perhaps an application for PC adjustments, expert settings, or a mobile app with parameter configuration capabilities.

But as a standalone device, the K7 doesn't need anything else to configure it, and that's a very positive advantage.

Happy Holidays

--Yes, we can selectively capture these specific sound frequency ranges and enhance them through algorithms to better distinguish directionality.
I'm not sure if the C3 allows signal processing before it reaches the audio system
--For example, in a PC → C3 → headphones setup, the C3 can process the audio signal before it reaches the headphone
Just a suggestion for improvement: perhaps an application for PC adjustments, expert settings, or a mobile app with parameter configuration capabilities.
--Yes, C3 has developed a dedicated application for this and supports PEQ, allowing users to freely configure the parameters


I have a few more questions:


1、Are you more of a gamer or a hi-fi enthusiast?
2、Why did you choose to purchase the K7?
3、Do you usually use the 4.4 mm output on the K7? Do you think this connector is necessary, or should it be removed?”*
