How to record cell phone calls on computer

So you want to learn how to record cell phone calls on a computer! You’re not alone. I did some search on the web and there are lots of people looking for that same answer.

The simple and free method is the speakerphone method, where just use your cell phone’s speakerphone setting and place a sound recording device next to the speaker. It’s the easiest way to record a cell phone conversation and will probably cost you nothing. Of course, the recording quality of this method is terrible. You’ll get a lot of noise from your surrounding. So let’s look into better options.

James Geeo a few months back asked the question “How can I record cell phone conversations?” on Engadget’s website. He wanted to record calls into his Sprint phone and was having a hard time finding hardware options to do so. One of the answers he got required him to use a mixing table.  That tells you that a simple question may not have a simple answer…

Mr. Stark asked the same questions in a more technical way “Is it possible to record sound from the TRRS jack?”. Fortunately, he was much luckier as Schiffer has a better answer for him: RECAP.  So let’s have a close look at what’s this device…

Record cell phone calls on computer

how to record cell phone calls on computerYou need a special audio adapter to let you record a cell phone call into a computer. The device is called the RECAP. What RECAP does is intercept the audio signals seen at the headset and convert them to the level that a PC or Voice Recorder can detect the sound. In essence, RECAP works like a signal splitter. Of course, it just not simply split the wires – that wouldn’t work. Instead, RECAP has the circuitry to adjust the signals to correct levels.

Technical details aside below is a quick snapshot showing how to connect up this handy audio adapter.

As seen in the picture, the connection is pretty straightforward: you plug in your headset into RECAP, then plug it in the phone’s audio jack. Then attached the connection cord from RECAP output to the PC MIC port.

If you don’t want to you the PC, you can also use it with a Voice Recorder and MAC, as long as those devices have a stereo MIC input port.

No special app required on the phone. Actually, that is one big advantage of this adapter. No need to pay for 3 way call apps that require subscription plans. RECAP is hardware and you own it outright!

In your computer should run the software to record the call. Windows ships with Sound Recorder or you can download a more powerful audio software such as Audacity. Best of it all, Audacity is free.

That’s all!

By the way, before you start recording, I recommend having a quick look at the laws about recording. Check out items #1 and #2 of this WikiHow article “How to Record a Phone Conversation“. 

Happy recordings!

How to Record Binaural or Stereo Sound Calls on Your iPhone and iPad

This article describes how to record cell calls in stereo, that is, recording using 2 audio channels. One channel (right channel) records your side of the call: your microphone picks up your voice. The other channel (left channel) records the other side of the call – the person you’re talking to on the phone. In this article, we refer to this recording setup as stereo recording or binaural recording.

Stereo recording, as described above, is ideal because it gives you the ability to monitor and manage each track individually. Oftentimes, in the real world, your voice and the other party’s voice are at different amplitudes and need to be equalized. So in short, stereo recording is a convenient way for achieving the best results, and simply a “must-have” for audio professionals.

Components Required

To get started, your iPhone / iPad stereo recording setup requires 3 devices listed below. More information about the adapters here, in our Knowledge Base

  • RECAP S2 audio adapter
  • Lightning to USB 3 Camera Adapter
  • USB Audio Interface with Stereo Microphone Input

Connection Steps

1. First, connect the Lightning to USB 3 Camera Adapter to the iPhone or iPad you want to record the call, then power it with a USB Power Adapter – that is, use your phone charger.

2. Then, you can connect the USB Audio Interface. This adapter gives you a 3.5mm stereo microphone input port where you can plug RECAP S2 output using the included cable.

3. Finally, plug your headset into RECAP S2, and RECAP into your phone, and you’re ready to start the recording.

After connecting the devices, as shown above, you are ready to perform a call recording. Make sure that you use an app that is capable of USB Audio recording. I have used an app called Auphonic. Check it out here []

Recording App Screenshots

In summary, the 3 screenshots above show: (1) Selecting AndreaMA as the input device in the recording app, (2) the start recording screen, with AndreaMA (Ch1) as the selected audio input, and (3) the recording with left and right channels captured, each showing distinct waveforms. And that’s how to record cell calls in stereo!

Configuring the Voice Recorder

record phone interviews into recorder

Only Voice Recorders with a stereo microphone input will work with RECAP. Check your voice recorder’s user manual to ensure it records in stereo. Note that some models can be configured between monaural and stereo modes, so make sure you have it configured as a stereo microphone before using it with RECAP.

Advantage of Stereo Recording

It’s handy that RECAP grabs the audio of a phone call in stereo. The left channel captures the sound you hear in the speakers, that is the audio coming from the party being interviewed. In the right channel it records your voice, picked up by your headset’s microphone.


Having separate channels for each party facilitate the audio post processing. It’s very convenient to have separate channels for your voice and the other party’s voice, because after recording takes place one would typically perform some audio processing to remove background noise picked up during the call and / or to amplify the speaker’s voice.


RECAP is a simple and useful tool for mobile journalists, reporters, lawyers, consultants and other professionals who wish to record interviews, client calls into their digital voice recorders.

I hope this article show RECAP is a great tool for professionals who are looking for audio equipment to record and broadcast phone interviews.

Phone Call During Live Streaming

Imagine you are a reporter broadcasting from the field using an iPad.

Say you want to interview a guest over the phone during your live streaming. How would you do that? Put the phone on speakerphone? That may work, but the quality is terrible. Now you can use RECAP C to get better sound quality.

Check out this email from one of our customers:

Let me tell you about our setup. I don’t if you heard of this, there’s a massive public protest happening right now in Kyiv, Ukraine and corporate-owned media weren’t covering events very well. So Hromadske TV was created to serve public interest. It broadcasts through Youtube Live ( often from the field using streaming from iPad.

A lot of people are calling during the broadcast to express their opinions and quick 1-5 min interviews are done live. At the moment, however there’s no connection between phone and tablet so the sound transmits just over the air which, of course, results in terrible quality. This is okay, because everyone understands that this is an amauter broadcast, not professional TV, but we’d like to get better. We’ll support your project to improve our quality. As the events uncover right now, I’d really like to get your devices sooner to serve our audience. Would definitely appreciate if you can help us.

– Sergii Kauk, Hromadske TV, Ukraine

If you’re a professional or amateur reporter and use RECAP C, let’s know! We’d love to hear from you.

Is it legal to record phone calls?

Recording phone conversations is legal in all of the 50 states and the District of Columbia. Federal law permits electronically recording a phone conversation with the consent of only one person involved in the conversation. This “one-party” rule requires the consent of at least one person in the conversation. The law deals primarily with wiretapping and law enforcement –- recording conversations to which the recorder is not a party. But for journalists, this means that only the reporter herself is required to know that the conversation is being recorded.” [1]

Rule of thumb: “you are always better off having the permission of the person you’re recording.”

“That’s the rule of thumb,” said Lucy Dalglish, executive director of The Reporters Committee for Freedom of the Press, which publishes “‘Can We Tape?’: A Practical Guide to Taping Phone Calls and In-Person Conversations in the 50 States and D.C.” “And that’s the ethical thing to do anyway. You always have to know what the law is, and you are always better off having the permission of the person you’re recording.”
