Voiceover – The New Catalog is Here!

February 24, 2015 by Dan Friedman

IMG_1791Other than checks and gifts there are few things that we in the voiceover industry receive in the mail that are quite as exciting as the ProGear catalog from Sweetwater. While I have made purchases with many retailers over the years, none of them offers a catalog quite as alluring as Sweetwater. The ProGear catalog is filled with plenty of photos and some really helpful tips on how to get the most out of the gear in your studio. The tech tips and Q&A interviews scattered throughout are worth much more than the weight they add to the catalog … and allow me to say that I don’t just get it for the pictures. 😉

(This year the Victoria’s Secret catalog arrived in my mail on the same day as the Sweetwater catalog. I scanned it thoroughly … twice … and found no helpful articles.)

If you are buying studio gear for the first time, want to upgrade and get the most bang for your buck, or simply have no interest in becoming a “techy,” then even the Sweetwater catalog (as sexy as it is … ahem, I mean informative) can be somewhat overwhelming. You just can’t try everything before you buy. So, how do you choose?

Just as we interpret scripts for meaning and subtext, we also have to interpret descriptions of the gear. For instance, if a microphone has a description that includes “vintage sound” that microphone probably has some characteristics that are noticeable or recognizable. This should probably be interpreted to mean that the microphone, although it may sound spectacular on many sources, may not capture our voice as purely as we would prefer. The microphone will have its own sonic character. A description that includes “accuracy” or “clean and clear” may be the better choice.

A microphone’s description may include the acronym “SPL” (Sound Pressure Level). This means the loudness level (or volume) of the source sound (e.g. – your voice). While we are not necessarily shouting, we may be close to the microphone for intimate reads. As such, the microphone may still be receiving a fairly significant amount of sound pressure level at close proximity. A microphone’s ability to handle high SPLs without distortion is important to us as voiceover artists.

The descriptions included with interfaces and preamps are filled with hyperbole. Once again, terms such as “accurate” and “clean” will be words to look for. Many of us work with multiple DAWs (Digital Audio Workstations) and travel with our gear, therefore “flexibility” and “portability” are terms to watch for as well. Preamps/Interfaces are easy to return or exchange if they don’t offer the level of quality you are hoping for. (Due to health concerns, exchanging microphones can be a bit more complicated. Be sure to check with your retailer regarding their return policies). Furthermore, you will often find another similarly priced preamp/interface from another manufacturer that will.

Truth be told, if you were recording an instrument with a broad range of frequencies such as a piano or recording an entire orchestra, the overall ability of your interface to capture those sounds would be critical. Your voice takes up much less sonic space. At the low end of the price spectrum you will not notice too many differences in an interface’s ability to capture sound (or differences listed in the catalog). However, there are a few areas where you will notice significant differences. One of the things that separates good quality gear from gear that is barely acceptable (or not at all acceptable in my opinion) is the sensitivity of the knobs. Small changes to the preamp on a physical knob should not cause dramatic jumps in signal level (up or down). Level changes should be as smooth as the knob you are turning essenceapotek. Another difference is headroom, or the ability of the preamp to produce an adequate signal level while still allowing you to increase the gain should you need it. Other critical differences are self-noise and the software and interface options they may or may not offer.

For studio monitors it is important to remember that you are working primarily with your voice. Therefore it isn’t necessary to have features such as “extended bass response.” Be sure to pay attention to whether the studio monitors are “powered” or “active.” This means they have their own amplifiers built into the speaker enclosure. Remember, the size of your listening environment will help determine what size studio monitors will best meet your needs. If you are going to be using your speakers in a small space, then “nearfield” monitors are the way to go.

Just like with studio monitors, headphones may offer a number of features you simply do not need when working with voice alone. However, there are some features you will definitely want to consider. A closed back design is one of those must-have features. This design helps reduce the possibility of sound being emitted by your headphones from leaking into your microphone. Headphone bleed is a sound you do not want to have to try to edit out of your recordings later. You’ll also want to be certain that the headphones you choose are comfortable as you may be wearing them for an extended period of time.

Hopefully, some of what I’ve shared here will start you on the right path. Clearly, every description is intended to influence you to buy. We can do our best to interpret greater meaning within these descriptions, but in the end, it will always come back to listening for yourself. Above all else, no matter what piece of gear you choose or which retailer you choose to purchase from, there is no substitute for a stellar performance and a great sounding recording environment.

Thank you Sweetwater for producing a catalog that is loved by everyone in our industry!

Recording Magazine’s Room Acoustics Series Part 5

September 28, 2011 by Dan Friedman

Recording Magazine sends out a newsletter to its subscribers every few weeks. The newsletter is (coincidentally) titled “Sound Advice” and this month it features the fifth in a series about room acoustics. Room acoustics is one of the biggest concerns for Recording Magazine readers. I know that this is also a big issue for those of you in the voiceover world. I asked permission to reprint this newsletter (and will ask to reprint the others in the series as well) so that those of you with home studios can also benefit from the information. I want to personally thank Brent Heintz, VP/Associate Publisher for granting permission, allowing me to share this great information with you.

Please visit Recording Magazine‘s website and Facebook Page.

Catch up or skip ahead: Part 1, Part 2, Part 3, Part 4, Part 6, Part 7, Part 8.

Here is the fifth newsletter in the series on Room Acoustics:

Welcome to Sound Advice on Acoustics! For the past several months we’ve been dealing with the basics of controlling bass buildup in rooms, using ratios of room dimensions and active bass trapping and other room treatments. Bass is by far the hardest problem to deal with in tuning a room, and with it under control, we can now turn our attention to the mids and highs. Read on…!So far we’ve considered the effects of low-frequency waves in the room. There are other issues, related to the propagation of mid and high frequencies. When a mid- or high-frequency sound wave moves through a room, it eventually hits one of the various boundary surfaces (walls, ceiling, floor). When this occurs, the sound wave is either absorbed, transmitted, or reflected.

Absorption means that some or most of the wave’s energy is converted into heat. Transmission means that the wave has some of its energy passed—through the wall, for example. Reflection means that most of the wave’s energy is directed back into the room.

This will happen repeatedly as the sound wave hits various surfaces until all its energy is eventually dissipated.

A room where all the surfaces are completely absorptive sounds dead and unnatural, and is unsuitable for music-making or listening. Such a room, called an anechoic chamber, would be used for testing purposes, as in the manufacture of loudspeakers for example, to isolate the sound quality of the speaker under test from the room effects. An overly reflective room is also not ideal—too many reflections tumbling around the room obscure the clarity of music or speech (see below).

An ideal room strikes the right balance between the original sound from the source (i.e. instrument or loudspeaker) and the amount of reflected sound present. Furthermore, it is desirable for the reflected sound to be distributed as evenly as possible throughout the room, providing a comfortable and pleasant sense of ambience (liveness). This even distribution of reflected sound energy is called , and is generally desirable, as we’ll see. But along the road to this ideal room, there are many pitfalls that we’ll now examine.

Reflection of sound waves is the behavior we’ll be most concerned with in the next few paragraphs. Just as happens with lower frequencies, when mid- and high-frequency waves reflect back into a room, the positive and negative peaks of the direct (original) sound waves and those of the reflections will cancel and reinforce. This happens because the reflections are delayed in time relative to the direct sound, causing their positive and negative peaks to be offset from those of the direct sound, which results in the interference (see Figure 5 for an illustration of this).

FIG:5A AND FIG:5B
In describing this, if we express the duration of a single cycle of a wave in measurements of phase, the delayed reflections as shown in Figure 5 can be said to be “out of phase” with the original sound. This phase-induced delay, or phase shift, is inevitable in any normal reflective environment.The short wavelengths of mid and high frequencies means that these cancellations and reinforcements occur more frequently all throughout the room rather than being clearly localized to specific broad areas as with standing waves. In a typical room, many complex interferences like this at higher frequencies result in changes in the frequency balance of sound in that room, as illustrated on a frequency response graph in Figure 6. This is called a comb filter response.
FIG:6

While this resulting frequency response may look very ragged, in actuality our hearing systems tend to average out and largely gloss over these subtle, myriad cancellations and reinforcements, and instead may perceive this as a not unpleasant coloration of the sound in a casual listening environment.

However, a recording studio is not a casual listening environment. For example, we depend on what we hear in the control room to make important decisions about the way the sounds in a recording blend and balance. We need to hear exactly what’s in the recording, not a “pleasantly colored” reproduction. Consequently, we need to exert some degree of control over any such effects that impact the neutrality of the monitoring environment.

With all this knowledge under our hats, it is time to look at another fundamental (excuse the pun) aspect of acoustics: how we hear. Next time: a crash course in how our ears and brains interpret sound. See you then!

The Voiceover Meet Up Group… What Do You Do?

September 7, 2011 by Dan Friedman

Dan Friedman, voiceover meet upThe voiceover community is well known for being a friendly, helpful and social community. Considering we sit in isolation for much of our lives it is no surprise that we need to get out once in awhile just to keep our sanity (assuming we have some to begin with of course). It is easier now than ever before to share our knowledge and seek the help of others when we need it. Seriously, how many social networking and meet up groups for VO are there now? Even with all of the technology that allows us to connect with one another over wires and through the airwaves, few things are more advantageous than actual face time.

There are at least three big events for voice talent coming up in the next several months, all before the end of this year (here in the US, I’m not sure about other countries) “Faffcon3” in September, “That’s VO” in October and the New York Mixer in December . They are being widely mentioned in social media and they all look really interesting and fun. I wish I could be at all of them (Anyone want to fly me out? Shameless… I know ;-)). But while all of these events will undoubtedly be filled with great information and amazingly talented people, this is about something a little closer to home… the local meet up group.

When I mentioned recently that I was going to be attending the meet up group in Charlotte, I received quite a bit of feedback from those wanting to be part of a meet up, start a meet up, or get one going again. I talked to Gabby of Voice Hunter (who organizes the Charlotte group) about all of the interest I had received and she said it was reasonably easy to get it going. The Charlotte group started out as a bunch of friends in the industry getting together and, over time, it developed into much more than that. I can only guess that this is how most of them start, but what information is critical to help keep the group going?

I began thinking about the various things that voiceover meet up groups could do to generate initial interest and more importantly, keep members coming back. For people already in the industry, getting to know other industry professionals can be informative or educational. For people new to the industry, access to working professionals is invaluable. Interest in voiceover as a career has never been higher and those who want to get into it need to learn from those who are already working professionals. Reading about the business is good; meeting and talking to people who work in the business is better.

Soon after I began writing this article I worked on a session with DB Cooper, who had recently attended a meet up/workout group in Los Angeles with Dave Fennoy. I heard Dave mention this workout group in an interview on the VAU. He emphasized the need for a comfortable environment to really work on scripts. This environment should be safe and confidential, so that everyone can succeed or fail, without worrying about clients or any of the bad stuff making it out into the public domain. Good thinking.

Everyone, new and experienced, benefits from the advice of guest speakers. Especially if these guests have information to offer that is outside the realm of expertise of the majority of group members. If someone is not local to your area, guests could easily attend with the help of Skype.

Performance is fun, but voiceover is a business and all topics related to business could certainly be beneficial to group members. Everything from accounting and billing to advertising, marketing, web design and even legal issues are critical to keeping a voiceover business flourishing.

Who can forget about the technical aspects of our business? Nobody. From microphones to mixing boards, there is plenty to discuss. Everyone in this business needs to understand the importance of choosing the right gear, how to set it up and what role room acoustics plays in overall sound.

Practice and in depth discussions on all of these topics can help voice talent with their careers. But, what I suspect may be the most critical element to keeping a meet up group together is support. Despite how it looks to the casual observer, voiceover is not an easy career choice. There are many disappointments, struggles and rejections. The competition is fierce. Having a local group of friends and trusted advisors, who truly understand what you do and can help you achieve your goals, is priceless.

I don’t personally run a group, although I have thought about starting one. Besides the groups in Charlotte and L.A., I know that Dallas also has a strong VO community and meet up group. I would love to get feedback from those who organize these and other meet up groups, and from those who participate. Share your knowledge, ideas and expertise over wires and through the airwaves (or right here in the comments section of my blog), to raise the bar for this industry and help other voice artists support each other much closer to home.
