Simple Device

Works as a simple audio splitter.

The call is captured and its signal is converted such that it looks like an ‘external mic’ for recording devices. All is done in hardware so no special apps are required!

RECAP is a recording solution for…

Business Calls

Record conference calls, client meetings, one-on-ones, presentations, and other important business calls. Advantages of recording include:

  • Share the recording with the team.
  • Focus on the meeting, not on taking notes.
  • It’s better than meeting minutes.

Podcasters & Reporters

Interviewing guests over the phone is a critical task for reporters & podcasters. Recap is the perfect solution as:

  • Keep guest’s routine – records both traditional and app calls (Skype, WhatsApp, Messenger)
  • Workflow – keep your editing, recording, and broadcasting tools.
  • Reliable – as you may only get one shot.


Record calls with family members, the cable company.  Remember all recorded calls will be stored locally in your computer, so no need to worry about your data being stolen in the cloud. There is no need to rely on 3rd party companies for securing YOUR personal information.

How to use RECAP, the phone call recording adapter?

RECAP goes between your phone and headset, as shown below, providing an output to a recording device.

Connection diagram showing how RECAP connects a phone, headset and recording device, so that calls can be recorded.

Compatibility: the “CALL” device must have a 3.5mm combo port and a compatible headset. The “REC” device must have a 3.5mm stereo microphone input port.

Note: Additional adapters are required if your device does not have the correct port. See FAQ below.

RECAP S2 has a stereo output. You get one channel on each side of the call, making the ideal technical solution for recording phone calls.

As shown in the sound amplitude diagram above, what you say in the microphone is delivered to the right channel, and what you hear on the call goes to the left channel.

Separate channels are ideal for audio processing. If you have an unbalanced call volume (one side much louder than the other), you can use an audio software tool, such as Audacity, to amplify the audio of one channel and balance it out.

Frequently Asked Questions

Q: My phone does not have a 3.5mm audio jack, can I use RECAP as the “CALL DEVICE”?

A: Sure! If you have an iPhone you’ll need this adapter – Lightning to 3.5 mm Headphone Jack Adapter. If you have an Android phone with a USB-C port, you’ll need a USB-C to 3.5mm Adapter. These adapters give you the 3.5mm headset port. See adapters here.

Q: My “RECORDING DEVICE” does not have a STEREO 3.5mm port, can I still use RECAP?

A: If you have a PC or Mac computer that has a USB port, you can add a USB Microphone adapter to give a stereo 3.5mm port. If you want to record into a phone or tablet, check out this article: How to Record Stereo Sound Calls on Your iPhone and iPad. See adapters here.

Q: My “RECORDING DEVICE” is a Digital Voice Recorder, does that work with RECAP?
