This Week in Sound: Reverberation Mapping & Singing Bacteria

A lightly annotated clipping service

These sound-studies highlights of the week originally appeared in the February 16, 2024, issue of the Disquiet.com weekly email newsletter, This Week in Sound.

I’ve been a bit busy — shifting tools around, and plotting, and working, and moderating, and writing, and staring at PCB boards (yes, that’s redundant), and practicing guitar (poorly, but enthusiastically), and reading. The tail end of winter exerts its own sort of cleansing, the digital in advance of the physical. Among those activities, this email newsletter has a new home on the web: it’s henceforth at thisweekinsound.disquiet.com. Nothing has changed about how This Week in Sound is published, but now the domain is my own (I’ve been at Disquiet.com since late 1996) and, thus, should I choose to alter my publication infrastructure down the road, the (virtual) location itself can persist. (This shift has been on my mind in anticipation of TinyLetter.com finally shutting down many years after Mailchimp bought it.)

And so I’m ending this week with 10 key sound-related things:

▰ 1. A STAGE DIRECTION: Fascinating interview with a theater director who emphasizes accessibility for the deaf and hard of hearing. The work being discussed here is a musical, Private Jones, about a deaf soldier, a sharp shooter, who fought in World War I: “‘If the piano does something that is supposed to evoke an emotion and there’s not a visual equivalent of that, we haven’t done our job,’ Pailet says. ‘Theater is taking psychology and turning it into behavior. So everything is visual, everything is behavioral, and it’s also therefore a perfect medium for sign language, which is a visual language. It exists to be seen.’” (Thanks, Mike Rhode!)

▰ 2. A MICROSOUND: Roberto Kolter, Professor of Microbiology, Emeritus, at Harvard Medical School, tracks his interest — via the Small Things Considered group blog — in the question of whether bacteria can sing, and upon learning that they can, ponders in turn what that might mean. Apparently “cells emit sound waves to carry information about their metabolic status,” he notes, quoting Gemma Reguera, another STC contributor: “Cells in communal settings, such as colonies, biofilms and microbial mats, are likely candidates to benefit from sound communication. Such close populations would allow the rapid propagation and detection of sounds, even at low intensities, and could cooperate to amplify the sound signal from individual cells.” (Thanks, Nicola Twilley!)

▰ 3. A VISUALIZATION: Follow through to a recent post by field recordist Mat Eric Hart who shares an example of how he sifts through more than half a day’s wildlife audio by first looking at the sound in a spectrogram to identify “significant audible events.”

▰ 4. A SCORE: After a long wait, the music — composed by Nicolas Snyder — from the first season of the fantastic animated series Scavengers Reign is finally available as a standalone album. In the show, the music is often indistinguishable from the on-screen activity, so it’s wonderful to hear the elegant music fully extracted from the story. Unless I’m mistaken, the release, from Milan Records, is not (yet) on Bandcamp, but it’s on all the streaming services. I previously wrote about the show’s sonic ecosystem.

▰ 5. A FLASHBACK: There is an intriguing creative tension between social media and ASMR, given that one is associated with dopamine rushes and the other with a more attenuated somatic state. Kate Lindsay of Embedded earlier this month shared a nine-year-old Q&A she did (apparently her first published freelance article, way back when) with the frequent ASMR poster CozyLotusASMR, who discusses how engagement varies by platform: “On TikTok, though, people could come across that video and you have no control if they like ASMR, if they know what that is. So sometimes you need to post something there that’s gonna grab somebody much faster, ’cause you have such a limited time to grab your audience. Whereas YouTube, they’re there for that. You don’t have to work so hard to grab their attention.”

▰ 6. A METAPHOR: Sound plays multiple roles in the research of MIT observational astrophysicist Erin Kara. For one she employs the increasingly common approach of sonification to “hear” the data that results from, in her case, research into black holes. But sound also provides a metaphor for her work with what is called reverberation mapping: “It’s akin to how bats use echolocation.They can’t see the dark cave that they’re flying through, but they know that the echo will come back at them with some delay, and they can use the fact that the echo is traveling at the speed of sound to map out the dark cave. We’re doing that, except with light traveling at the speed of light.”

▰ 7. A PROTEST: The word “deepfake” has become inherently associated with malfeasance, but parents of children killed in school shootings are employing AI to revive their deceased offsprings’ voices in order to enlist them in efforts to impact legislation. “It sounds like an episode of ‘Black Mirror,’” wrote Joanna Stern in the Wall Street Journal, “and the surreality seems to be at least partially the point.” (Tangential: “FTC Wants to Penalize Companies for Use of AI in Impersonation.”)

▰ 8. A LESSON: It’s not a musician’s duty to be eloquent about their music, but when they are, it is a unique and palpable pleasure, an example being when pianist Brad Mehldau discusses such topics as his early education, playing in groups where others stake out his harmonic territory, and distinctions he has noted between jazz standards and newer pieces (such as those by Radiohead and Neil Young he has covered), a key characteristic being that the latter generally originated on guitar.

▰ 9. A QUESTION: I’m currently reading two books about guitar pedals: Pedal Crush and Boss Book (which surveys the entire Boss line). Have you read a good book that provides insights into the transition from analog to digital guitar pedals? I’m especially interested in devices that store audio in memory (loopers, memory buffers — I think I’m wondering about delays, too). Thanks.

▰ 10. A STUDY: This will blow your mind, but cities are noisy — among other congestion-related problems — and science shows that green spaces ease the impact. A study in Nature involving 190,200 participants helped confirm the assumed: “The evidence points to the need for nature-based interventions, such as optimizing urban greenness for healthy cities with lower stress levels and related health burdens.”

Scratch Pad: Questions, URLs, Milestone

From the past week

I do this manually at the end of each week: collating (and sometimes lightly editing) most of the recent little comments I’ve made on social media, which I think of as my public scratch pad. Some end up on Disquiet.com earlier, sometimes in expanded form. These days I mostly hang out on Mastodon (at post.lurk.org/@disquiet), and I’m also trying out a few others. I take weekends and evenings off social media.

▰ I’m on many Discords related to sound/music, too many to track closely. I pay attention to 12k and Linear Night Market. I just signed up for Wildfire Laboratories. I peek Earth Modular, Decibels Sonification, Omri Cohen, and DivKid. Any strong recommendations (more related to sound than music)?

▰ Reeder / Feedly / iCloud question: if you use Reeder, do you (still) use Feedly, or is iCloud sync sufficient? Seems like iCloud would be. Thanks.

▰ Do itch.io sites not natively have RSS feeds?

▰ Nice. My sound studies newsletter, This Week in Sound, has passed the 4,000-subscriber milestone.

▰ Looks like threads on Threads are broken or at least malfunctioning, maybe worse than on Bluesky. I added two posts to a thread of graphic novels I’ve read in 2024, and neither of those posts shows either under Threads or Replies if you go to my /@dsqt page on Threads. They’re only visible in the original thread. On Mastodon lengthy threading works fine.

▰ I now understand that tote bags are bumper stickers for pedestrians

▰ I’m enjoying Georges Perec’s Life: A User’s Manual but the lists do get to be a little much after awhile

▰ It didn’t occur to me to check usage of the acronym (actually initialism) “TWiS” when I began using it to abbreviate This Week in Sound. Fortunately there are few (six on Acronym Finder), none NSFW. Oddly, one’s from KDVS, where I did a radio show in the early ’90s.

▰ Speaking of newsletters, the weekly Disquiet Junto project announcement has fully moved to Buttondown (from TinyLetter), at juntoletter.disquiet.com, and the automated send worked well. I can now set the project post on disquiet.com and newsletter to go live while I’m asleep, right at the start of each Thursday (Pacific time).

▰ I’m routinely receiving email newsletters where the subject line has nothing to do with the specific material in the newsletter, from authors speaking at bookstores to news items amid current headlines. I can’t tell if this is a database error, a UX hitch, or a bizarre “engagement strategy.”

▰ I was in the middle of two novels. Now I’m in the middle of three. Well, I’m well into three.

▰ I finished reading four graphic novels this week: Léa Murawiec’s The Great Beyond, a fable about social media and pursuing fame, echoing fabulists like Dash Shaw, Winsor McCay, and Bryan Lee O’Malley. A simple story told in complex way. Throughout I thought, “Please don’t end [that way].” It did. Still, breathtaking at times — comics as parkour. Volume 1 of Jeff Lemire’s horror series Gideon Falls, art by Andrea Sorrentino. The individual issue covers may be my favorite part. And volume 2 of Gideon Falls, in which past and present — near and far, trauma and fate — all connect. This is a horror comic, so not exactly a big surprise. Volume 11 of The Fable, a manga about a hitman ordered to take a year off killing: It’s clear the plan wasn’t good, as too many factors make it impossible for him to be anonymous, and he ends up turning into something akin to a superhero (the action in the film adaptations is quite something at times). Like a lot of thrillers, it has a bit of a stacked deck thing happening.

Tags “Я” Us

A little UI alteration

Made a little tweak to Disquiet.com regarding tags. Tags now yield simpler index views (rather than a long page of the full text of each article), so it’s easier to find (and flip backward through) interrelated material.

Examples:

https://disquiet.com/tag/live-performance/
https://disquiet.com/tag/junto/
https://disquiet.com/tag/field-recording/
https://disquiet.com/tag/comics/

There’s also, at the bottom of the page, a different system for going backwards and forwards through pages. That approach will likely roll out to the rest of the website in the near future.

Disquiet Junto Project 0633: Voice Swap

The Assignment: Rerecord all or part of one of your tracks using just your voice.

Note: This week’s project instructions are considerably more concise than has been the case in the past. What was previously around 580 words (not including the project steps and any other project-specific information) is now closer to 280. Like a contract, the project template had expanded over time — a clause here, a rule there — as I added clarifications based on participant input and on my observations about activity. The newly refined Disquiet Junto project template loses nothing and is more readable, meaning more people may actually read it, and it will — I hope — be less off-putting to newcomers.

. . .

Each Thursday in the Disquiet Junto music community, a new compositional challenge is set before the group’s members, who then have five days to record and upload a track in response to the project instructions.

Membership in the Junto is open: just join and participate. (A SoundCloud account is helpful but not required.) There’s no pressure to do every project. The Junto is weekly so that you know it’s there, every Thursday through Monday, when your time and interest align.

Tracks are added to the SoundCloud playlist for the duration of the project. Additional (non-SoundCloud) tracks appear in the lllllll.co discussion thread.

These following instructions went to the group email list (via juntoletter.disquiet.com).

Disquiet Junto Project 0633: Voice Swap
The Assignment: Rerecord all or part of one of your tracks using just your voice.

Step 1: You’re going to attempt to rerecord something you’ve done before, this time using your voice as the source audio. Think of a track you’ve recorded previously that might recommend itself for such an adaptation.

Step 2: Needless to say, this won’t be particularly easy. But best you can, redo the track you selected in Step 1 by replacing the source audio with your own voice. (And, of course, if you can’t do it completely, use your voice for as much of it as you can. And you can still process your voice, certainly.)

Tasks Upon Completion:

Label: Include “disquiet0633” (no spaces/quotes) in the name of your track.

Upload: Post your track to a public account (SoundCloud preferred but by no means required). It’s best to focus on one track, but if you post more than one, clarify which is the “main” rendition.

Share: Post your track and a description explanation at https://llllllll.co/t/disquiet-junto-project-0633-voice-swap/

Discuss: Listen to and comment on the other tracks.

Additional Details:

Length: The length is up to you. 

Deadline: Monday, February 19, 2024, 11:59pm (that is: just before midnight) wherever you are.

About: https://disquiet.com/junto/

Newsletter: https://juntoletter.disquiet.com/

License: It’s preferred (but not required) to set your track as downloadable and allowing for attributed remixing (i.e., an attribution Creative Commons license).
