JK Audio CellTap 4C lets you record split-channel phone/VoIP calls on any recorder

Record phone and VoIP conversations from a mobile device into any 3.5 mm stereo recorder with JK Audio’s new CellTap 4C!

The CellTap 4C connects to a smartphone, tablet, or other mobile devices via a 3.5 mm TRRS cable (combined input and output). Connect your TRRS headset (such as the Apple EarPods) and you’ll be able to hear and speak to your phone-calling guest. Then, connect a standard TRS (stereo) 3.5 mm cable from the CellTap 4C to any stereo audio recorder.

CellTap 4CThe result is that you’ll get a split-track stereo recording of your call. Your audio will be on the left channel and your guest will be on the right. Then, use your editing software to split these to separate mono tracks and you’ll get full editing and processing control!

The 3.5 mm TRS (stereo) record line can connect to any stereo recording device: Zoom H1, Zoom H5, Roland R-05, a computer with stereo line-in, and such. As long as the recording device is stereo, you’ll get both sides of the conversation.

The CellTap 4C isn’t just for recording phone calls! You could use it for any VoIP calling system—Skype, Google+ Hangouts, FaceTime audio, and more. This will work with any Android, iOS, or Windows smartphone or tablet! It could even work on modern PCs with the combine headset audio jack (TRRS).

This is an ideal option for remote podcast interviews with very little gear.

JK Audio’s CellTap 4C is now available for under $100.

    Wow. No mixer. Hm.

  2. Chuck says:

    I have an audio interface (with mixing software), and I use an iRig2 for a similar purpose. I’ve found you have to set the switch to FX and use the 1/4 inch out to amplifier jack in order for it to work. The caller can hear me through my XLR mic plugged into the interface and I can hear them through my headphones all without feedback once a mix that excludes the phone’s input is set up.

    1. That’s certainly another way to do it. This device is really for simple recording with TRRS devices.
