VAM 011 | Microphone Basics, Part 1 – Dynamic vs. Condenser

Welcome to episode 11 of the Voice Acting Mastery podcast with yours truly, Crispin Freeman!

In this episode, I explain the basics of how a microphone works. I also outline the differences between the two dominant types of microphones in voice acting, dynamic and condenser microphones.

Historically, microphone technology was the responsibility of the recording engineer. It used to be that you could spend your entire voice acting career not knowing how a microphone worked as long as you knew which side of it to talk into. Those days are now gone. In the age of the internet, voice actors are expected to be able to make professional quality recordings from their home studios. A solid understanding of microphones and how they function is invaluable to understanding how to use the most important tool a voice actor has.

While there are many different types of microphone technology, there are two that have become dominant in the world of voice over:

  1. Dynamic Microphones
  2. Condenser Microphones
Both have their pros and cons and both are useful in different situations. Because each captures sound in fundamentally different ways, it’s important to understand their nuances to use them to their best advantage.

Here are some pictures of the two microphones I mention in the podcast, the Shure SM58 Dynamic microphone and the Neumann U87 Condenser microphone:

Shure SM58 – Dynamic



Neumann U87 – Condenser

    I was JUST looking through buying a new microphone when this popped up! Such useful information!

    What’s your opinion on the Samson CO1U? It’s a condenser mic that most VAAers have. Is it worth investing in?

    I’m kinda outgrowing less-than-par recordings with unwanted white noise, however small. And Rockband mic is getting slightly worse and worse with recording lately.

    How often should you change your mics? If at all?

    Thanks in advance!

    • Crispin Freeman says:

      There are many USB mics that are fine for amateur projects. The Samson is one of them. However, if you want to sound competitive with the professionals, the Shure PG42USB microphone is the one to go with. I’ve heard that people have also had good experiences with the Blue Yeti, but I’m not the biggest fan of their mics. I bought the Shure 42USB myself and have done some tests against my Neumann and the Shure sounds really good. I’m going to be using the Shure to record on my iPad in the future!

      Ideally, you shouldn’t have to change your mics. Microphone technology hasn’t really changed much since the 1960s. The Neumann U87 has been the industry standard for more than 50 years. If you buy a nice microphone and take care of it, you never need upgrade. My first professional microphone was an Audio-Technica 4033. It was a relatively inexpensive condenser microphone for around $300. Eventually, I grew out of that microphone and into the Neumann I use today and will probably use forever. I’m still using my Sennheiser MD421 as my travel mic and plan on using it forever. I just got the Shure PG42 to use with my iPad since I can’t use the MD421 with the iPad. If you buy an industry standard microphone, it never goes obsolete. Your interfaces and recording technology will change, but the microphone won’t.

      Hope that helps.

      • Kalyn McCabe says:

        All right! I was going to put a new mic on my Christmas list, I didn’t know which to go with. I tend to have super expensive Christmas lists. I’m so terrible! My poor parents!

        Thanks for the advice!

  2. Angelican Marcos says:

    Such big information I can’t keep up with my head but very educational and I thank you for this podcast about which microphone to use I should try this sometime but at least which microphone I can use to do voice acting Merci Mr. Freeman
    Angelican Marcos 🙂

  3. Ryan Ashlight says:

    Certainly very helpful information with respect to microphones and what a VA should know about them.

    I do have a few questions however, particularly with respect to dynamic mics and a comment you made earlier about recording on your iPad.

    When you’re on the road and you need to record something, given the choice, would you prefer to record something on your iPad or something like a laptop? And given how well a dynamic records, is this even a concern in the first place? Noticeable differences, if any?

    Thanks very much, and looking forward to the next podcast as always.

    • Crispin Freeman says:

      I haven’t recorded on my iPad as much as I’ve recorded on my laptop. Obviously, I’m more familiar with recording on my laptop and have access to better tools on my laptop. Using my iPad to record auditions when I’m on the road is just to have the option in case I don’t want to bring my whole laptop rig.

      Right now, there’s no easy way to use a dynamic microphone with an iPad unless you buy a USB dynamic mic. So I’m using the Shure PG42 condenser with my iPad. We’ll see how it goes.

      Ideally when I’m on the road, a dynamic is usually more flexible in terms of dealing with room noise, but you gotta do what you gotta do. If I can only get pro-quality sound out of a USB condenser mic, then the Shure PG42 it is with my iPad.

  4. Maxwell Myers says:

    Such a valuable episode! I’ve had some trouble doing research in comparing microphones for VO actors all over the internet, and you go sum it all up in ten minutes for me 🙂 I feel much more confident in knowing where I stand with my current mic (AT2020 USB), and now I finally know that terminology they print on the box :p
    Also, it’s comforting to know that any future technology won’t make these microphones obsolete. It sure makes the idea of saving up much more appetizing! Can’t wait for the next episode!

    • Crispin Freeman says:

      So glad you enjoyed the episode and that it wasn’t too technical for you! I’m also glad you understand the value of your microphone now. It can give one a greater sense of mastery to understand the mechanics behind things.

  5. Kayla says:

    I am going into animation but I had to learn about microphones in fundamentals of audio from my college. I prefer dynamic microphones, since I don’t like borrowing condensers, they are worth so much. That and the atmospheres in which I record sounds usually have a lot of unwanted background noise such as air conditioners and things. Unless I was recording Foley for an animation I would have to get a Condenser mic.

    • Crispin Freeman says:

      It’s true, dynamic microphones can be much better at rejecting noise in a less than ideal recording situation. They just require better amplification to sound their best. Sounds like you’ve found a system that works for you.

  6. Matthew Ray says:

    Do you have a preferred compressor setting for voice acting (Besides threshold of course since that varies on input source). If not what are some of the things I should listen for in using a compressor for mixing voice acting? Thanks

    • Crispin Freeman says:

      I do not have a “preferred” compressor setting. I use different settings depending on what I’m doing.

      Everyone has their own “special sauce” settings for their compressors. In promos and trailers, they use a lot of dynamic compression, whereas in animation they try to use very little. It depends on the task at hand.

      Sorry I can’t be more specific, but it really depends on what you’re trying to accomplish.

  7. Alex Da Silve says:

    I was looking on craiglist for good and cheap mics and I found a AK A515 type V Condenser Mic. In great condition for $50. Is it a good mic. for beginners? Also is it worth the price?

    Thank you Crispin

    • Crispin Freeman says:

      I am not familiar with that microphone so I don’t have any opinion about it. I don’t know if it’s good or not. I can’t possibly keep track of every microphone that is out there.

      I can only recommend microphones that I am familiar with. There are certain microphones that get used over and over again in voice over. Those are the ones that I recommend in my Toolbox Section.

  8. Ed Moran says:

    I’ve recently purchased my first professional quality microphone. I took your advice and picked up a PG-42 … except that it isn’t the USB version. (Yay, my first mistake!) I’ve seen that there are XLR to USB cables available. Do you have any experience with those? If so, do you think I’ll be fine with one of those or if there are problems with hooking things up that way? Note that I’m still very new to this and right now, I’m just looking to get comfortable with the sound of my voice and to experiment. Thanks for all the advice you’ve given me already and keep doing what you’re doing!

    • Crispin Freeman says:

      Sorry you ended up getting the normal, XLR version of the PG-42 and not the USB version. I recommend the USB version just to make it simpler for people who may not be as technically inclined with audio equipment. The normal, XLR version is great too though, you’ll just need to use a USB audio interface to connect it to your computer.

      As far as I’m aware, there’s no such thing as an XLR to USB cable. XLR is an analog audio cable while USB is a digital computer interface. They couldn’t be more different from each other. Usually what is required is an interface that digitizes the analog signal generated by the microphone and transmits that digital information via USB to your computer. In the toolbox section I recommend a couple of different XLR to USB interfaces including the CEntrance MicPort Pro. You will need to use some sort of USB audio interface to make your XLR PG-42 work with you computer.

      Hope that helps!

  9. Hello! I know this is an older podcast, but I’m new tuning into them. I thought I would let you know that I noticed amazon offers a package deal on the blue yeti microphone, if you’d like to update your toolbox for novice voice artists. The kit comes with the microphone, JVC headphones, pop filter, and microphone stand adapter for $139.99. It may be useful for anyone starting out!

    I’ve posted a link below,
    All the best!

    • Crispin Freeman says:

      Thanks for the link! Unfortunately, many times those packages disappear after a while so I usually don’t link to them directly. Also, I’m not familiar with those headphones so I’m not sure I can recommend them whole-heartedly.

      After reading some of the reviews, people don’t seem too happy with the package. They like the mic, but not the pop filter. I’ve never seen a standard pop filter attached to a Blue Yeti that way, but maybe it works. I just don’t know.

      But thank you for offering to give people another package that could work for them. I appreciate it.

      Also, I shortened your URL for you. Hope you don’t mind.

      • Francesca Hogan says:

        Oh my goodness, my apologies for not being more thorough! I didn’t read the reviews. It popped into my recommendations while looking for studio headphones.

        I’m always on the lookout for a good sale, but quality can’t be sacrificed!

        No worries on the URL. It was a mouthful for sure! 🙂

    Hey Crispin, Adam here from the UK. I’ll be posting a review on iTunes too, but I wanted to ask your opinion. I’m a Dad of two with a Full Time job as a customer trainer I’m on pretty good money. Now I have been on various sites for the past couple of months applying and auditioning for various voice acting work. Currently I’m looking alot of ranges to try and “find my voice”. I’ve not had much success so far, but I’m hopefull and will persevere.. Anyway, I was hoping to sometime soon sign up to some sort of course too. BUT being a Dad of two O have responsibilities and I wondered f you could help with transitions to this new line of work. As you say you need to be flexible and I want to be flexible but I feel untill I have some experience I wont be able to commit fully without having to make sacrifices.. what do you think? Great podcast!! I know I’m a little behind but I love the short bursts of info each episode provides! All the best. Adam
