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 optionsâ€Šfor recording guests remotely –â€Što 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 correctâ€¦

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 ofâ€¦

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.

“Shades of Gray” (52:00 mp3):

An audio mosaic about abortion in America:

“Shades of Gray” (52:00) Jonathan Mitchell & Ahri Golden

Pro-choice. Pro-life. Most people have already chosen sides in the ongoing debate, so why revisit the issue? Shades of Gray shares a range of stories told by people young and old who have been directly affected by abortion, instead of the polemics of irreconcilable extremes. It’s a carefully crafted audio mosaic and a stark portrayal of the intensely personal nature of our relationship with abortion. This is the fair and frank discussion America rarely has but desperately needs.

Eleven: Sara and Pogo

Damn this guy’s good, another Pogo creation:

This is my remix of an original song by SaraSinger42:Â youtube.com/SaraSinger42

The video was shot by Sara’s mother, singer and song writer Jackie Messenger: youtube.com/JackieMessenger. Sara is part of a beautiful family who have always been wonderfully supportive of me.

This track came about almost immediately when I found Sara’s channel. I wondered what her song would sound like with a beat, so I spent around 10 minutes knocking together a drum sequence before layering in her song. 45 minutes later, I seem to have spontaneously put together a complete track.

HV132- Musicality of Speech

Host: Barrett Golding of Hearing Voices
Airs week of: 2012-02-15

This program contains copyrighted material not licensed for web-streaming, so we cannot offer an mp3 of this week’s episode.

A history of what composer Steve Reich calls speech-melodies:

“It’s Gonna Rain” (1966 / 1:00 excerpt)
“Come Out” (1966 / 3:00 excerpt) Steve Reich

“It’s Gonna Rain” was composed in San Francisco in January 1965. The voice belongs to a young black Pentecostal preacher who called himself Brother Walter. I recorded him along with the pigeons and traffic one Sunday afternoon in Union Square in downtown San Francisco. Later at home I started playing with tape loops of his voice and, by accident, discovered the process of letting two identical loops go gradually out of phase with each other.

In the first part of the piece the two loops are lined up in unison, gradually move completely out of phase with each other, and then slowly move back to unison. In the second part two much longer loops gradually begin to go out of phase with each other. This two-voice relationship is then doubled to four with two voices going out of phase with the other two. Finally the process moves to eight voices and the effect is a kind of controlled chaos, which may be appropriate to the subject matter – the end of the world.

“It’s Gonna Rain” is the first piece ever to use the process of gradually shifting phase relations between two or more identical repeating patterns. The second was “Come Out.” Composed in 1966, it was originally part of a benefit presented at Town Hall in New York City for the retrial, with lawyers of their own choosing, of the six boys arrested for murder during the Harlem riots of 1964. The voice is that of Daniel Hamm, now acquitted and then 19, describing a beating he took in Harlem’s 28th precinct station. The police were about to take the boys out to be “cleaned up” and were only taking those that were visibly bleeding. Since Hamm had no actual open bleeding he proceeded to squeeze open a bruise on his leg so that he would be taken to the hospital.

“I had to like open the bruise up and let some of the bruise blood come out to show them.” More…

a transect – Due East

Walking, maps, and art — some of my favorite stuff — are all wrapped up in one project, “a transect – Due East:”

A body of work based on a series of cross-country hikes that enabled me to generate visual and written notation, correspondence, interviews and historic research. The location is specific to my homeland in the San Joaquin Valley of California where I traveled due east into the foothills and Sierra Nevada Mountains.

It’s like these 1940s movies were made just so, 70 years later, they could accompany the music of Clothesline Revival:

Clothesline Revival has a couple HV connections. They helped create a mess in our Food Fight episode. And we produced the NPR Story “Clothesline Revival’s ‘Long Gone’” (also check NPR’s “Music Review: ‘Of My Native Land’ from Clothesline Revival“).

CR samples extensively from ancient audio archives, especially in their first two CDs, Of My Native Land and Long Gone. Their latest, featuring “Voice of the Lobster” — the song in the vid — is They Came From Somewhere.

“Voice from Tahrir” (52:00) Human Rights Watch

January 25, 2011. One year ago, a revolution began in Cairoâ€™s Tahrir Square. For the next eighteen days, millions of Egyptians across the country would demonstrate in the streets, demanding the end of their 30-year dictatorship. They were inspired by Tunisians, whose protests, that same month, had forced out the authoritarian regime of President Zine El Abidine Ben Ali. Now it was time for Egyptian President Hosni Mubarak to go.

A few weeks after the protests, the advocacy group Human Rights Watch interviewed some of the organizers of the January uprising: union leaders, civil rights workers, young social media activists, family members of of murdered protestors, and mothers who brought their kids to Tahrir to clean after the protests.. These Human Rights Watch interviews provide a rare, eyewitness account of a revolution, told by the Egyptian people, the activists, human rights defenders, and bloggers who persevered during those eighteen days.

The hour features recordings made in the square by reporters and citizen jounalists from around the world, including Daniel Finnan of Radio France Internationale, Al Jazeera, Egypt Daily News, Ramy Roof, and Matthew Cassel of Just Image.org.
