Recording studio Survival Guide

Posted on by

When it comes to recording studios, it’s easy to obsess over gear—the mics, preamps, monitors, and plugins that shape your sound. But while equipment is critical, it’s often the overlooked details that make or break a session. A forgotten cable, an overheated amp, or even a lack of snacks can grind the creative process to a halt. That’s where this Studio Survival Guide comes in. It’s a practical checklist for everything beyond the gear—cleaning supplies, tools, food, and creature comforts—that keeps sessions running smoothly and everyone focused on making great music.

Computerism (noun)

Posted on by

Computerism (noun): A form of discrimination or bias where individuals are judged, stereotyped, or treated differently based on their choice of computer operating system (e.g., macOS vs. Windows vs. Linux) or browser preference (e.g., Chrome vs. Safari vs. Firefox). This phenomenon often manifests as social stigma, exclusion, or assumptions about a person’s technical skills, personality, or values based on their technology preferences.

For example, a macOS user might be labeled as “trendy but impractical,” while a Linux user could be stereotyped as “overly technical” or “elitist.” Similarly, browser preferences might spark debates or judgments about privacy, efficiency, or mainstream conformity.

“Jason’s blatant computerism was evident when he refused to collaborate with Sarah, simply because she preferred macOS over Windows.

A computerist is someone who engages in or perpetuates discrimination, bias, or stereotyping based on another person’s choice of computer operating system, software, or browser. They may judge or treat others differently because of their tech preferences, often making assumptions about their personality, competence, or values.

For example, a computerist might mock someone for using Internet Explorer, assume all Mac users are creative professionals, or stereotype Linux users as overly technical and antisocial.

In a broader sense, a computerist could also describe someone deeply passionate about computer systems and their associated cultures, though this usage is less common.

“Don’t be such a computerist—just because I use Linux doesn’t mean I think I’m better than everyone else!”

 

 

The aesthetic of quality

Quote

Posted on by

Something that appears to be of high quality or sophistication but lacks true substance or craftsmanship. It’s the idea of presenting an illusion of excellence—through design, branding, or superficial elements—without the underlying integrity or value. In other words, it’s a deceptive or inauthentic display meant to mimic true quality, often relying on surface-level attributes rather than genuine merit. This can be seen in products, services, or even experiences that seem premium at first glance but ultimately fall short when examined more closely.

 

 

“Access is the medium”

Quote

Posted on by

“Access is the medium” describes the shift from physical ownership of media (books, CDs, DVDs, etc.) to a digital world where the primary way to consume content is through access, typically via subscriptions or paywalls. Instead of purchasing individual pieces of media, users now gain temporary access to vast libraries of content, often behind paywalls or through streaming services. In this paradigm, access itself becomes the medium through which content is delivered and consumed, emphasizing convenience and immediacy over ownership.

The last meter

Quote

Posted on by

“The last meter” refers to the final connection between an audio device, such as a microphone, headphones, or speakers, and the larger sound system or network. Just as “the last mile” in telecommunications represents the crucial final stretch that delivers service to the end user, “the last meter” in audio engineering highlights the importance of the final cable or wire, which directly impacts the quality and reliability of the sound being transmitted. Despite its short length, this connection is critical for ensuring the integrity of the overall sound system.

Neutrik adopts AES72-4E – for QTP

NEUTRIK AES72-4E QTP RJ45 Twisted Pair Audio Network Solutions PDF

https://www.neutrik.com/en/product/na-4i4o-aes72

06/02/2024 – Neutrik Launches: NA-4I4O-AES72

The NA-4I4O-AES72 is a 4-channel stagebox for transmitting microphone levels, analog line levels, AES3, DMX or even intercom via one single CAT cable. The device has male and female XLRs in the same housing and can be used directly as a splitter for monitoring. An additional etherCON serves as feedthrough and allows further looping of the signals to other devices. A ground lift at each input prevents possible ground loops. In addition, each input connector offers the possibility to invert the signal.

Metric Frame Rates: Banishing the Bizarre

Posted on by

Metric Frame Rates: Banishing the Bizarre

In a digital world governed by binary precision, there is a ghost in the machine. It appears in the settings menus of our cameras and the export windows of our editing software. It is the spectral presence of fractional math: 23.976, 29.97, and 59.94.

These numbers are messy. They are relics. It is time we fully embraced a concept that brings sanity back to video: Metric Frame Rates.

Defining the Metric Frame Standard

What are Metric Frame Rates? They are the clean, integer-based measurements of time that align perfectly with the way we count seconds. They are the logical progression of temporal resolution:

* 25 fps: The cinematic baseline.

* 50 fps: The standard for smooth, lucid motion.

* 100 fps: High precision and clarity.

* 200 fps: Extreme fluidity and slow-motion capability.

Unlike the fractional legacy standards, these rates—25, 50, 100, and 200—do not require a calculator to determine how many frames exist in an hour of footage. They are absolute.

The NTSC Hangover: Where the “Weird” Came From

To understand the beauty of Metric Frame Rates, you have to look at the chaos they replace.

For decades, North America and parts of Asia have been stuck with the “NTSC” standard. Originally, black and white television ran at a clean 30 frames per second. But when engineers added color in the 1950s, they hit a snag: the color signal interfered with the audio signal.

Their solution? Slow the video down by exactly 0.1%.

Suddenly, 30 fps became 29.97 fps. 60 fields per second became 59.94. Cinema’s 24 fps was slowed to 23.976.

This “fractional frame rate” created a nightmare for editors and engineers. Timecode became a headache (Drop-Frame vs. Non-Drop Frame). Audio drifted out of sync over long durations. We have been carrying this baggage for over half a century, long after the analog cathode-ray tubes that required it were thrown into landfills.

The Elegance of the Metric System

Metric Frame Rates (rooted historically in the PAL/SECAM regions and 50Hz power grids) bypassed this absurdity. They stuck to the integers.

1. The Mathematical Harmony

Metric rates scale perfectly.

* 25 fits into 50 exactly twice.

* 50 fits into 100 exactly twice.

* 100 fits into 200 exactly twice.

This base-2 geometric progression makes frame-rate conversion, math, and compression algorithms significantly more efficient. If you shoot at 100 fps and want to slow it down to 25 fps, the math is flawless: play every frame for 4x slow motion. No “pulldown” patterns, no jitter, no ghost frames.

2. 25 fps: The Aesthetic Sweet Spot

While Hollywood clings to 24 (or the dreaded 23.976), 25 fps offers a nearly identical aesthetic experience with a slightly higher temporal resolution. It retains the “dreamlike” quality of film without the fractional headache.

3. 50 fps: The Reality Standard

50 frames per second is the metric answer to the “soap opera effect,” but used correctly, it provides the “being there” feeling required for news, sports, and documentation. It captures reality with fluid precision, free from the flicker of lower rates.

4. 100 and 200 fps: The Future of Clarity

As we push into high-refresh-rate displays (120Hz, 144Hz, 240Hz), Metric Frame Rates like 100 and 200 are becoming vital. They offer a hyper-real smoothness that 29.97 can never achieve. Furthermore, 100 fps serves as the perfect “universal donor” for slow motion—fast enough to capture high-speed action, but mathematically simple enough to conform down to 50 or 25 for delivery

We no longer live in an analog world of interfering radio frequencies. We live in a digital world of absolute values.

There is no technical reason for a modern digital creator to be forced to use 29.97 unless they are broadcasting to legacy television networks. For the rest of us—creating for the web, for streaming, and for the future—it is time to reject the bizarre numbers of the past.

It is time to standardize on the clean, logical, and precise integers of 25, 50, 100, and 200.
