Yes, you can convert RCA to USB, but only with an active capture device that digitizes the analog signal — a passive cable will never work.
- You use an RCA-to-USB capture card or active adapter
- Your computer or phone has a USB host port
- You have drivers or software like OBS installed
- You use a passive RCA-to-USB cable with no chip
- Your source outputs digital coaxial S/PDIF instead of analog RCA
- Your USB device is output-only and cannot receive input
Why You Need an Active Device
RCA carries analog audio and video signals. USB carries digital data. These are fundamentally different, so a simple wire cannot bridge them. An active capture device contains a built-in analog-to-digital converter (ADC) chip that translates the RCA signal into a digital stream your computer can read over USB.
Skipping the active converter is the single most common mistake. If a listing just says “RCA to USB cable” with no mention of a chip, driver, or software — it will not work.
Common Use Cases
- VHS or DVD to PC: Plug your VCR or DVD player’s RCA output into a capture card, connect the card to USB, and record with OBS or the bundled software.
- Turntable to laptop: An RCA-to-USB audio adapter (such as the UGREEN RCA-to-USB-C model) lets you digitize vinyl directly into Audacity or any DAW.
- Mixer to phone: The same USB-C audio adapters work with Android phones that support USB audio input.
Setup Comparison Table
| Setup | Works? | Need | Note |
|---|---|---|---|
| VCR RCA → USB capture card → PC | Yes | Capture card + OBS | Records video and audio |
| Turntable RCA → USB-C audio adapter → laptop | Yes | Active USB audio adapter | Audio only |
| RCA → passive USB cable → PC | No | — | No ADC chip inside |
| Digital coaxial S/PDIF → USB | Rarely | Specific S/PDIF interface | Few converters available |
What to Buy
For video capture, budget RCA-to-USB capture cards are available for under $10 on Amazon and work reliably for standard-definition footage. For audio-only, look for a USB audio interface or a dedicated RCA-to-USB adapter from a manufacturer like Renhotec, which makes purpose-built RCA-to-USB converters. Always confirm the product listing mentions an ADC chip or analog-to-digital conversion before buying.

Bottom Line
You can convert RCA to USB, but the word “convert” is key — an active digitizing device is non-negotiable. Pick the right capture card or USB audio adapter for your source, install the required software, and the process is straightforward and affordable.
