How to record long-distance audio interviews in a time of social distance and studio shutdowns.

Prepared for the podcasters at Teaching Tolerance (Southern Poverty Law Center)

In times like these, entering a professional recording studio isn’t smart or, often, possible. Rather than stop our recording schedules, let’s adapt. Let’s find options for recording guests remotely – to get us through current and future emergencies.

The solution must be easy to use and hard to mess up, for hosts and for guests. Audio won’t be studio quality but it must be good. (Each part of the production process — edit, EQ, mix, encode — loses a little more audio fidelity. So the better the quality of the original recording the better the audio left in the end product.)

My best cost/sound recommendations:

For host tracks, set up a simple home studio for each host.

For guest interviews, use a remote-recording service audio service.

Details follow (loaded with Transom and other links). Please comment and correct

Simple Home Studio

Yes: For host.
No: For guests (but maybe mic).

Hosts: A simple set-up makes sense for the host, with an external USB mic (and pop filter), good headphones, basic but foolproof recording software, and portable/storable acoustic baffles.

Guests: It’s prohibitively complicated and error-prone to walk guests through all the software-install, record, and upload procedures. But it is feasible to mail guests a USB mic (or headset), with a prepaid return label. [Update coming: this is impractical in viral times. (Thx, Shea)] (If no external mic, ask if they have the wired Apple headphones: Its lavalier mic is better than using a computer’s, mainly due to mouth proximity.)

Video Conferencing Services

No: Except when unavoidable.

We moderns are all video-chat savvy. And video-conferencing services record (instructions for: Skype, Google Hangouts, GoToMeeting, Zoom). But their audio recordings are all low fidelity.

Zoom seems best for sound:

  • Records at 32kHz sample rate (AAC, mono, ~52 kbps bitrate). The others have a much lower 16KHz sample rate (AAC, mono, 64 kbps), so less frequency range and more chance of distortion and audio artifacts (weird noises).
  • Can make separate audiofiles for each user. The others mix all the voices into one file.
  • Gives you an audio and video file. Most others are video-only, so you need to strip the audio out.

Zoom settings: record multiple files

While down this rabbit hole I discovered:

150 milliseconds [is] the maximum latency before conversations feel unnatural. Zoom works really hard to stay under 150 milliseconds, Chief Product Officer Oded Gal said. Or maybe this: Rather than optimize the connection for all devices — which means optimizing for the worst, slowest one — Zoom tends to each individually.
Protocol

And I know people have, use, and like Skype, but: Skype requires extensive credits during the podcast (beginning, end, and every 15 minutes). While there are ways to improve the fidelity of Skype’s audio recordings, like Call Recorder (Mac) and Evaer (Win), those third-party apps still don’t match the ease, features, and quality of…

Remote Interview Audio Recorders

Yes: Whenever possible.

A recent crop of made-for-podcasters, remote-audio services record hosts and guests in different places. Two of the best are Zencastr and SquadCast (which I’m leaning toward). Both have inexpensive monthly subscriptions. Both work like this:

Starting the recording:

  1. The host logs into the recording service and starts the session.
  2. The guest goes to to a custom URL (sent by the host).
  3. The interview and recording take place via the browser (i.e., no software installs needed).

During the recording:

  1. Local recording: Full-fidelity uncompressed audio records onto host and guest computers (WAV, 44.1kHz, 16 bit).
  2. Progressive upload: Hi-fi MP3s uploads to the cloud (so nothing lost if connection breaks).
  3. Auto-backup: As the host/guest cloud MP3s upload, those files are simultaneously copied.
  4. Auto-upload (local file): As soon as the host stops the recording, the WAVs (recorded locally onto host/guest computers) upload to the cloud.

SquadCast dashboard

Just like video-conferencing, the conversation happens over the internet (VoIP), which is bandwidth limited so loses audio fidelity. The recording, however, doesn’t use internet audio: It captures each participant’s computer input (the mic plugged- or built-in) then writes the recording directly onto their harddrives — no audio lost.

The browser controls it all, using WebRTC, which I won’t explain because Adam Ragusea of Current already did a stellar job: “How three services for recording remote audio interviews stack up: ipDTL, Zencastr and Ringr”. (I’ll just mention it works on Chrome, Firefox, and Edge, but not yet Safari.)

We’ll be testing the following two remote-interview recording services (and updating this post) soon. Both are well-liked by reviewers and work similarly, with a few differences:

SquadCast

SquadCast‘s advantage is their option to open a video screen (not recorded). Seeing each other speak improves the rhythm of a conversation.

They have a nonprofit discount, a free trial, but no free plan for subscriptions. Recordings upload to their cloud service. (They don’t specify where: Amazon, Azure, their mom’s basement?)

Their support docs have plenty of videos but lack screenshots: a faster way to convey computer info. But their FAQ, How to Be a Guest page, and how-to intro video are good.

Zencastr

Zencastr deserves cred for their COVID response, removing recording-hour limits on their free Hobbyist plan. Recordings upload to the user’s own Dropbox account.

They have no video screen option. (I’m a big fan of f2f interviewee interaction.) Of course, neither do tape syncs or two-way studio interviews.

Their support site is screenshot-less but has a slew of how-to videos and explainers.

Smartphone Syncs

No: Except when unavoidable.

Finally, lots of folk have posted lots of ways to record iPhone interviews (like Transom, StoryCorps, and Hearing Voices / Marketplace). But remote recording means transforming all our guests into capable recordists: color me skeptical.

Silence Among Friends

SALT cast/PRX logoWhile catching up on SALTcast‘s, I caught this gem, a radio story about silence at Quaker meetings, “Silence Among Friends” by Joni Murphy (12:07 mp3):

Reparations

She takes money only from white folks, and gives it to blacks who pass by. Her sign reads: “200 Years of Slavery in the United States. Reparation payments accepted here.” damali ayo is a street performance artist. “I offer people a convenient opportunity to pay for the unpaid labor of African Americans.” This piece is part of her “living flag” project.
