  • Designing Legendary Gear with Paul Wolff

    26/06/2017

    Paul Wolff has designed more legendary pieces of gear than most of us have used. In his years with API alone, Paul designed the 550B EQ, 512 and 3124 mic preamps, Legacy console, and 2500 compressor. He was recently honored by NAMM TEC hall of fame for inventing the Lunchbox and 500-series format, which he helped turned into a cottage industry. I was honored to have Paul on the podcast to discuss console design and how he's seen the industry change in the last 40 years. Just a few of the things we discussed: The origins of the 500-series How Steve Perry became the first customer of the Lunchbox The uphill battle to make gear that’s authentic to the API sound What happened in 1978 to change the sound of most audio equipment Paul's opinion that cloners "should be burned to death” Download the mp3 or subscribe via iTunes Some Notes on API Jargon As much as I try to keep our podcasts fairly jargon-free, I was guilty of using a lot of API model numbers without explanation this episode. These are: 550A: Late 60

  • Analog Synth DIY with Abby Echiverri

    27/04/2017

    I've often fantasized about building a huge analog synth. But besides the obstacles of cost and not having a spare room in my house for it, I've always found the DIY synth world to be a bit intimidating. In this podcast, synth wizard Abby Echiverri walks me through the basics, such as: Is it feasible to build your own synth? How much should I budget? What are the basic modules I need to build? Abby is a composer, DJ, DIYer, and audio gear designer. I caught up with her when she was on the road as the synth/keyboard tech for Soulwax. Download the mp3 or subscribe via iTunes

  • Chassis Design with Jon Erickson

    16/02/2017

    We audio nerds love to talk about particular parts and circuitry—transformers, op-amps, discrete vs integrated, passive vs active, etc—but we rarely discuss the biggest part and the one we actually interface with the most: the chassis. In this episode of our resurrected podcast, I talk to Jon Erickson about the ins and outs of chassis design and manufacturing. Jon Erickson has been involved with some of the most delicious-looking audio gear on the market: the A-Designs Pacifica preamp, JHS Pedals' line of 500-series modules, and his flagship Tonecraft 363 DI/preamp.

  • "Explain Like I'm 5": Filters (Podcast #12)

    05/02/2016

    How do filters work? As audio engineers, we use filters every day. We're all intimately familiar with high-pass, low-pass, band-pass, shelf, etc. filters. But how do they actually work in analog gear? The basic operating principles of analog filters are actually very simple. In this quick (10 minute) podcast, Peterson and Chris explain the very basics of high-pass and low-pass filters so that any 5-year-old could understand.

  • "Explain Like I'm 5": Why Is Pro Audio Gear So Expensive? (Podcast #13)

    05/02/2016

    Sticker shock is a common malady in the recording world. It takes a lot of money to outfit and maintain a studio. But why? What are the factors that drive the price of professional recording gear? Why does gear cost so much more than the sum of its components? Are the prices justified, or is someone getting ripped off? In this month's podcast, Peterson and Chris discuss what goes into the cost of a piece of gear, and how you can short-circuit some of these costs by doing it yourself.

  • Podcast #4: Being a DIYer, Studio Owner, and Engineer with Marc Alan Goodman of Strange Weather Brooklyn

    17/02/2015

    One thing I often wondered when I first got into DIY was whether any "real" producers and engineers built their own gear. So I was thrilled to visit Marc Alan Goodman at his studio Strange Weather in Brooklyn to see his DIY gear and talk to him about how DIY fits into his career as a successful studio owner and engineer. We recorded some video of Marc's DIY gear which you can see below. After my camera ran out of batteries, we sat down and chatted about lots of DIY stuff. Download the MP3 file or listen on Subscribe to the podcast! Topics covered: Becoming your own studio tech The ecstasy and agony of trying to do everything yourself Marc's involvement in the Harrison Ford Filter project Marc's thoughts on the LAZ EQN, Neve-style EQ (of which he built 16!) How DIY is as old as the profession of audio engineering DIY: business or hobby? Electricity as the true medium of a recording engineer The vintage U87 project (of which he built 3!)

  • Podcast #2: What Makes API Gear Sound So Good? With Jeff Steiger of ClassicAPI

    17/02/2015

    Jeff Steiger of CAPI and I get nerdy about various vintage audio and DIY topics, including: Why create a company dedicated to vintage API gear? Why not Neve, SSL, etc.? Will we ever see ClassicAPI kits in a 1RU rack format, instead of 500-series? Why does old API gear sound so good when it's specs are so bad? The sonically stunning Gar2520 opamp Jeff's new, two-stage preamp design, the VP28 How Jeff tried to cram a full API console strip into one 500-series slot. "Inventory management is a bitch." How DIY gear is beginning to penetrate the big-budget recording world. Are we seeing a return to the early days of recording when many engineers built their own custom gear?

  • “Explain Like I’m 5?: Audio Levels (Podcast #11)

    17/02/2015

    What's the difference between "pro" and "consumer" line levels? Is it ok to plug an instrument into a line level input? What's the difference between peak and RMS levels? In the long-awaited return of our "Explain Like I'm 5" podcast series, Peterson and new DIYRE team member, Chris, explain the basics of audio levels. Download the mp3 or subscribe via iTunes Topics discussed: Can you damage equipment by plugging the wrong thing in? In analog audio Volume = Voltage The difference between peak and RMS volume RMS is a way of measuring AC as if it were DC The most common levels you'll encounter in the studio: +4dBu, pro line level (1.22V) -10dBV, consumer line level (.316V) Mic level Instrument level Tangent: why are microphone output levels so low?

  • Podcast #6: "Everything You Always Wanted to Know About Audio Electronics..." Part 2

    17/02/2015

    Our resident electronics expert, Duncan Gray, is back to answer your audio electronics questions! Duncan and I recorded two hours of answers last week to the questions you asked in the original "Everything You Always Wanted to Know About Audio Electronics..." post. So to spare you the tedium of digging through 120 minutes of audio to find the answer to your questions, we've split our conversation up into smaller, more easily digestible podcast. Stick with us until the 33 minute mark, where we answer my favorite question so far that gets to the heart of the amazing relationship between audio and analog electronics. Download the mp3 or listen on iTunes . Subscribe to the DIYRE podcast In today's 45 minute segment we cover: "What troubleshooting process do you recommend when your PCB-based project isn’t working?" "What audible impact does input/output impedance have on the connected equipment. The effect it has upon the amount of voltage transferred is clear, however a more comprehensive explanation on how impe

  • "Explain Like I'm 5": Balanced vs. Unbalanced Connections (Podcast #8)

    17/02/2015

    This podcast marks the first of a new series in which I attempt to explain complex audio subjects so that a 5-year-old could understand them. In this first "Explain Like I'm 5" podcast, I tackle the important subject of balancing. What is the difference between balanced and unbalanced connections? How does balancing work? Why do we need balanced connections? In less than 15 minutes, I answer these questions the way I wish someone had for me: assuming no electronics knowledge, sticking to the basics, and using only terminology that a musician would understand. Download the mp3 or subscribe via iTunes In order, I discuss: What are balanced and unbalanced connections? How can I identify the difference? Why are there these two types of connections in the studio? How does balancing reduce noise? What is Common Mode Rejection Ratio (CMRR)? If balanced connections are so great, why isn't everything balanced?

  • "Explain Like I'm 5": Impedance (Podcast #9)

    17/02/2015

    When I sent out the newsletter announcing the last "Explain Like I'm 5 Podcast," I asked which audio topics you wanted to hear explained to a 5-year-old. As as result I now have a list of over 25 topics for future shows! But the response I got the most was "impedance." One reader even taunted me: "Haha, explain impedance like I'm five..good luck with that ;)" Challenge accepted, buddy! Impedance is one of those audio concepts that comes up at almost every recording session or live sound gig, even if you're not aware of it. Grasping the basics of input and output impedance can make you aware of potential problems before they happen, and help you problem solve more quickly and confidently. And the truth is that the fundamentals of impedance are simple enough that you can learn them from a 15-minute podcast. In today's ELI5 podcast, I begin with a discussion of acoustics before moving to electronics to show you that you already know more about impedance than you probably think. I go on to cover exactly what inpu

  • Podcast #10: Talking Tubes with DW Fearn

    17/02/2015

    DW Fearn knows tubes. Since he rediscovered the sound of tubes in 1991, DW (Doug) has crafted a legendary line of all-tube, all-red-front-paneled recording gear. In April I had the pleasure of visiting Doug at his home and workshop outside Philadelphia. Doug and I sat down on either side of a ribbon microphone and had a great conversation about tubes, electronics, and sound. During our conversation Doug tells the story of how he returned to tubes after decades of operating an all sold-state studio, and outlines the theory behind why tubes and transistors sound different in a clear and straightforward way. Download the mp3 or listen on iTunes . Subscribe to the DIYRE podcast Topics discussed: How Doug pieced together his first console from standalone amplifiers What happened when he replaced that tube gear with a solid-state console "We couldn't admit that it didn't sound good, so we just got used to it." How a demo tape from college in 1966 led him back to building tube amps "We didn't listen to recorded m

  • Podcast #5: Is Open Source the Way Forward for DIY Audio?

    17/02/2015

    DIY audio folks like to share--that's what makes us a community. My kits and the DIY Project Directory are possible because others have shared their research, schematics, designs, etc. without any legal limitations. In turn, I document my projects so that anyone who cares to can learn from, tweak, or improve upon them. So, while the greater audio world remains largely closed, with patents, secrecy, and lawyers protecting intellectual property, our little DIY corner is very much an "open source" environment. But unlike explicitly open-source communities such as Wikipedia or GitHub, our openness is not formalized into licenses or explicitly agreed upon. In podcast #5 I talk Eric Jennings of Pinocc.io, an open-source, wireless hardware platform, about how an open source approach might look for the DIY audio community. Topics discussed include: Is openness a viable way forward for the DIY audio world? What exactly does open source mean for a hardware-based industry? Does open source encourage cloners and copycat

  • "Everything You Always Wanted to Know About Audio Electronics" Answers Podcast! (pt. 1)

    17/02/2015

    Last week, I put out the call for you to ask "Everything you always wanted to know about audio electronics, but were afraid to ask." The response was awesome, and a tad overwhelming: almost 50 questions! I want to sincerely thank all of you who posed questions, we got some great stuff. On Saturday our volunteer expert, Duncan Gray, joined me to answer your questions podcast style. Download the MP3 file or subscribe via iTunes Here's what we covered in chronological order: How Duncan got into audio electronics (as usual, it involved breaking something) Circuit talk: What does class-A mean? Why is it desirable? How do I measure the total current draw of modules in a 51x rack? How do I choose the right power supply for a given DIY project? What's the difference between an LC and RC filter? What happens to the Q, or bandwidth, in a swinging input EQ topology? What's the simplest way electronically to make a noise? Why do parts of a circuit go to ground? How should I ground inside the box? What is star grounding

  • Podcast #7: Talking Mic Preamps and Surface-Mount Parts with Expat Audio

    17/02/2015

    In this month's DIY podcast, I talk to Dafydd Roche of Expat Audio about their new Eden Mic Preamp. Download the mp3 or listen on iTunes . Subscribe to the DIYRE podcast Dafydd and I get into some good stuff about mic preamp and general audio design, including: The difference between surface mount (SMD/SMT) and through hole components in terms of sound and performance. Are SMDs good for audio? Should we audio folks resist industry's march toward all surface-mount parts? The concept of "parasitics" in audio electronics design and when their effects can be critical. Dafydd gives us a guided tour of the Eden circuit from the input to output jacks--a great way to get a grasp on the basics of mic preamp design.
