How to Record a Phone Interview for Your Podcast (August 2026)

by

Recording a phone interview for your podcast sounds simple until you try it and end up with audio that sounds like it came through a tin can. I learned this the hard way years ago when I lost a 45-minute interview with a guest I had spent three weeks booking. The recording app crashed, and I had nothing to show for it.

That experience sent me down a path of testing every recording method I could find. From Zoom calls and dedicated podcast platforms to built-in phone features and professional hardware setups, I have tried them all across hundreds of episodes.

Learning how to record a phone interview for your podcast comes down to matching the right method to your guest’s technical comfort level. A tech-savvy guest can handle a dedicated recording platform. An older interviewee or someone calling from their car needs a simpler approach.

In this guide, I will walk you through five proven methods for capturing clean, broadcast-quality phone interviews. I will also cover audio quality tips, backup strategies, legal considerations, and troubleshooting fixes for the most common problems podcasters face.

By the end, you will know exactly which approach fits your show, your guests, and your budget.

How to Record a Phone Interview for Your Podcast: Method Overview

The best way to record a phone interview for your podcast depends on three factors: your guest’s tech comfort, your budget, and how much audio quality matters to you. Here is a quick breakdown of the five methods I cover in detail below.

1. Video conferencing software (Zoom, Google Meet). The most accessible option. Your guest likely already has it installed, and you can record separate audio tracks locally. This is where I recommend most podcasters start.

2. Dedicated podcast recording platforms (Riverside, Zencastr, Descript, Cleanfeed). Purpose-built for podcasters with local recording, progressive uploads, and automatic noise reduction. Higher quality than Zoom but requires your guest to use a browser link.

3. Direct phone call recording (iPhone built-in, Google Voice, third-party apps). Best for guests who insist on a traditional phone call or are in areas with poor internet. Quality is lower but convenience is unbeatable.

4. Double-ender recording. Each person records their own audio locally, then you combine the files afterward. Produces studio-quality sound from both sides of the conversation.

5. Hardware mix-minus setup. Professional broadcasters route phone audio through a mixer with a mix-minus circuit to prevent echo. This is the gold standard but requires equipment and technical know-how.

For most podcasters, I recommend starting with Zoom or a dedicated platform and adding direct phone recording as a backup. If you interview guests regularly and want the best quality, the double-ender method is worth the extra effort.

Method 1: Record Using Video Conferencing Software

Zoom is the tool I have used most often for remote podcast recording, and for good reason. Almost everyone has it installed, it records local audio files for each participant, and the settings give you surprising control over sound quality.

Google Meet works similarly and is free, but Zoom’s recording features are better suited for podcasters. I will focus on Zoom here, but the principles apply to most video conferencing tools.

Step-by-Step Zoom Setup for Podcast Recording

Step 1: Create and schedule the meeting. Send your guest a calendar invitation with the Zoom link. Include instructions asking them to use headphones and find a quiet room.

Step 2: Enable local recording of separate audio files. Before the call, go to your Zoom settings, navigate to the Recording tab, and check the box that says “Record a separate audio file for each participant.” This gives you isolated tracks you can edit independently.

Step 3: Turn on original sound and high fidelity music mode. In audio settings, enable “Original Sound” and select “High Fidelity Music Mode.” Zoom normally compresses audio to save bandwidth, but these settings reduce that compression significantly.

Step 4: Ask everyone to use headphones. This prevents speaker audio from bleeding into the microphone and creating echo or feedback. I cannot stress this enough. No headphones means echo problems almost every time.

Step 5: Start recording before the interview begins. Record locally on your computer, not just to the cloud. Local recordings capture full-quality audio files directly to your hard drive.

Step 6: Export the separate audio tracks. After the call ends, Zoom processes the recording and creates a folder with individual audio files for each speaker. Import these into your editing software.

The biggest advantage of Zoom is familiarity. Your guest does not need to learn anything new. The downside is that even with optimized settings, Zoom still compresses audio more than dedicated podcast platforms do.

Method 2: Use Dedicated Podcast Recording Platforms

If you want better audio quality than Zoom without the complexity of a double-ender, dedicated podcast recording platforms are the sweet spot. These browser-based tools record audio locally on each person’s device and upload it automatically as you record.

I have tested several of these platforms, and they all work on the same principle: instead of relying on compressed call audio, each person’s voice is captured by their own microphone and saved as a clean, uncompressed file.

Riverside

Riverside records separate audio and video tracks locally at up to 48kHz uncompressed. If your internet drops mid-recording, the file keeps recording locally and uploads when the connection returns. This progressive upload feature has saved me more than once.

Your guest just clicks a link and joins from their browser. No app installation required.

Zencastr

Zencastr works similarly, recording each guest locally through their browser. It includes built-in post-production features like automatic noise reduction and level normalization. The free plan lets you record up to 8 hours per month.

I like Zencastr for shows with two or three regular co-hosts because the interface is clean and simple.

Descript

Descript combines recording with AI-powered editing. You record the conversation, then edit by modifying the transcript text. It also includes Studio Sound, which uses AI to clean up noisy recordings.

If you want to minimize your post-production workflow, Descript is hard to beat.

Cleanfeed

Cleanfeed is a browser-based tool popular with radio broadcasters. It focuses on live audio streaming with low latency and offers a free tier that supports single-track recording.

Cleanfeed is a good choice if you need to interview guests live or want to stream the conversation directly to your station.

For multitrack podcast recording, Riverside and Zencastr are my top recommendations. Both isolate each speaker into separate files, giving you full control during editing.

Method 3: Record a Phone Call Directly

Sometimes the only option is a traditional phone call. Your guest might be traveling, have unreliable internet, or simply prefer picking up the phone. In those cases, you need to know how to record the call itself.

Phone call audio will never match what you get from a dedicated platform, but you can still produce a listenable episode with the right approach.

iPhone Built-In Call Recording (iOS 18 and Later)

Apple finally added native call recording starting with iOS 18. This feature lets you record both incoming and outgoing calls directly through the Phone app without any third-party software.

Step 1: While on a call, tap the new recording button in the call interface.

Step 2: An automated voice announces that the call is being recorded, which handles consent notification for you.

Step 3: When the call ends, the recording appears in your Notes app as an audio attachment.

Step 4: Open the note, tap the audio file, and save it to your Files app for transfer to your editing software.

This is a game-changer for podcasters who previously had to rely on workarounds or third-party apps. The announcement feature also means you do not have to awkwardly tell your guest you are recording.

Google Voice Call Recording

Google Voice lets you record incoming calls for free. This is one of the oldest methods for recording phone interview podcast audio, and it still works reliably.

Step 1: Set up a Google Voice number if you do not have one already.

Step 2: During an incoming call, press 4 on your keypad to start recording.

Step 3: Press 4 again to stop recording, or simply end the call.

Step 4: The recording saves automatically to your Google Voice account.

Step 5: Download the MP3 file from the Google Voice website.

Google Voice only works for incoming calls, not outgoing ones. Ask your guest to call your Google Voice number, or use a service that forwards calls to it.

Third-Party Recording Apps

Several apps can record calls on both iPhone and Android. Look for apps that record locally rather than using a three-way call service, since local recording produces better quality.

On Android, apps like Cube Call Recorder can capture VoIP calls from Zoom, WhatsApp, and other apps. On iPhone, options are more limited due to Apple’s restrictions, but Rev Call Recorder offers free incoming call recording.

Always test your recording setup with a friend before the actual interview. Call recording apps can be unpredictable, and you do not want to discover problems after the interview is over.

Method 4: The Double-Ender Technique for Studio-Quality Audio

The double-ender is the method professional podcasters use when audio quality is the top priority. The concept is simple: each person records their own voice locally, and you combine the files afterward.

Because neither recording depends on the internet connection, the result sounds like both people were in the same studio. There is no compression, no dropouts, and no lag artifacts.

How to Set Up a Double-Ender Recording

Step 1: Connect via phone or video call. You need to hear each other during the interview, so use any communication tool. Zoom, a regular phone call, or even Skype all work fine here because you are only using it for monitoring, not for the final audio.

Step 2: Each person records their own audio. Both you and your guest use recording software on your own devices. Audacity is a free option that works on any computer. QuickTime on Mac or the Voice Recorder app on Windows are even simpler.

Step 3: Everyone wears headphones. This is critical. Without headphones, the call audio bleeds into the local recording, defeating the entire purpose of a double-ender.

Step 4: Clap once at the start. Have both people clap loudly at the same time before the interview begins. This creates a sharp audio spike on both recordings that you can use to sync them perfectly in your editor.

Step 5: Record the full interview locally. Do not stop recording on your local device until the interview is completely finished, even if you take breaks.

Step 6: Collect the files. Have your guest send you their recording file after the interview. A service like Dropbox, Google Drive, or WeTransfer works well for large audio files.

Step 7: Sync and combine. Import both files into your editing software, line up the clap spikes, and you have a studio-quality interview.

The main barrier to double-ender podcast recording is getting guests to follow instructions. Some guests will not be comfortable installing software or pressing record. For those guests, fall back to Zoom or a dedicated platform.

Method 5: Hardware Mix-Minus Setup for Professional Callers

If you record phone interviews regularly and want broadcast-quality results, a hardware mix-minus setup is what the pros use. This method connects a phone call directly to your audio mixer or interface, bypassing software compression entirely.

A mix-minus circuit sends the caller’s voice to your headphones and your microphone to the caller, but it prevents your audio from being sent back to the caller. Without this loop prevention, you get echo and feedback.

What You Need for a Mix-Minus Setup

You need a mixer or audio interface with an aux send or mix-minus feature, a phone hybrid or adapter, and quality headphones. Popular options include the JK Audio Broadcast Host, the Behringer Xenyx mixers with aux sends, or the RodeCaster Pro which has mix-minus built in.

The RodeCaster Pro is the easiest entry point. It handles mix-minus automatically, lets you connect a phone via Bluetooth, and records multitrack directly to a microSD card.

When to Use Hardware Over Software

A hardware setup makes sense if you produce a daily or weekly interview show, if you need to record live phone calls on air, or if you want the absolute highest quality available. For occasional interviews, the cost and complexity are not justified.

I only recommend this path after you have outgrown software solutions and can identify specific limitations that hardware would solve.

Audio Quality Best Practices for Phone Interviews

No matter which recording method you choose, these practices will dramatically improve how your interview sounds. I apply every one of these on every episode.

Wear closed-back headphones. Over-ear headphones prevent audio from leaking into your microphone. Earbuds work in a pinch, but avoid using speakers under any circumstances.

Use a dedicated microphone. Even a budget USB microphone sounds better than a built-in laptop mic. If your guest does not have one, suggest they use the earbuds that came with their phone, which have a surprisingly decent microphone.

Record in a quiet, soft-surfaced room. Kitchens and bathrooms have hard surfaces that create echo. Bedrooms and living rooms with carpets, curtains, and furniture absorb sound. Close windows and turn off anything that hums.

Position the microphone correctly. Keep it 4 to 6 inches from your mouth, slightly off to the side so you do not breathe directly into it. If you are using earbuds, hold the microphone near your chin rather than letting it dangle.

Do a sound check before the interview. Record 30 seconds of test audio and listen back. This catches problems like low volume, background noise, or echo before they ruin your actual interview.

Record at 48kHz sample rate in WAV format. WAV files are uncompressed and give you maximum quality for editing. You can convert to MP3 for publishing later. Avoid recording directly to compressed formats.

Mute notifications. Put your phone on do-not-disturb and close email and messaging apps on your computer. A single notification sound during a quiet moment can ruin a recording.

Ask your guest to do the same. Remind them before you start recording to silence their devices and stay in one place. Moving around causes audio level fluctuations that are tedious to fix in editing.

Backup Recording Strategies: Never Lose an Interview

I started using backup recording after losing that interview I mentioned at the beginning. Now I record everything twice, and it has saved me on multiple occasions.

Always run two recording systems simultaneously. If you are using Zoom, also start a local recording on your computer with QuickTime or Audacity. If the Zoom recording fails, you still have your side of the conversation.

Use progressive upload platforms. Riverside and Zencastr upload audio chunks as you record. If your connection drops or your computer crashes, the portion recorded up to that point is already saved on their servers.

Save as you go. If you are recording locally in Audacity or another editor, save the project every 10 minutes. A power outage should never cost you more than a few minutes of audio.

Ask your guest to record too. Even if you do not plan to use their file, having a backup from their side means a safety net. This is essentially a lightweight double-ender that serves as insurance.

Before you record any phone interview, you need to understand the legal requirements around call recording. This is one of the most underserved topics in podcast guides, and getting it wrong can have real consequences.

Know your consent law. In the United States, recording laws fall into two categories: one-party consent and two-party (or all-party) consent.

In one-party consent states, only one person on the call needs to know the recording is happening. Since you are the one recording, your knowledge is sufficient. However, I always recommend telling your guest anyway for ethical reasons.

In two-party consent states, every person on the call must agree to being recorded. These states include California, Florida, Illinois, Maryland, Massachusetts, Michigan, Montana, Nevada, New Hampshire, Pennsylvania, and Washington. If you or your guest is in one of these states, you must get explicit consent.

State your recording intent clearly. Start every interview by saying you are recording. Something as simple as “Just so you know, I am recording this conversation for the podcast” covers you in most situations.

Get written consent when possible. A quick email confirmation before the interview stating that the conversation will be recorded and published gives you documented proof of consent.

International interviews add complexity. Laws vary by country. The European Union has strict privacy regulations under GDPR. If you are interviewing someone in another country, research that jurisdiction’s recording laws.

Is it okay to record virtual interviews? Yes, as long as you follow consent requirements. Recording virtual interviews on Zoom, Riverside, or any other platform is legal when proper consent is obtained from all participants.

Troubleshooting Common Phone Interview Audio Problems

Even with perfect preparation, things go wrong. Here are the problems I encounter most often and how to fix them.

Problem: Echo on the recording. This almost always means someone is using speakers instead of headphones. Ask everyone to switch to headphones and the echo disappears immediately.

Problem: Guest audio is too quiet. Ask your guest to move closer to their microphone or move the microphone closer to their mouth. If they are using a laptop, suggest an external earbud microphone which is naturally closer to their face.

Problem: Robotic or choppy audio. This is an internet bandwidth issue. Have your guest switch from Wi-Fi to a wired connection if possible, or move closer to their router. Turning off video in Zoom also reduces bandwidth load on the connection.

Problem: Background noise from the guest’s side. Suggest they move to a quieter room or record closer to their microphone. In post-production, tools like Descript Studio Sound or Adobe Podcast Enhance can clean up a lot of background noise.

Problem: Dropped call or disconnected recording. This is exactly why backup recording matters. If the primary recording drops, your backup system continues running. Always have a second recording method active.

Problem: Audio sounds compressed or muffled. This happens when you rely on phone line audio or default Zoom settings. Switch to original sound mode in Zoom, or move to a dedicated platform that records locally for better fidelity.
