1. How Anyone Can Create Professional Sounding Audio www.homebrewaudio.com Ken Theriot Home Brew Audio

2. What does it take to get professional sounding audio? You’re not alone. Most folks do. www.homebrewaudio.com

5. If you know what you're doing, you can get decent audio from the cheapest gear. But lack of knowledge causes lots of folks to produce crappy audio even with expensive gear! www.homebrewaudio.com Disclaimer: Better quality gear can and does sound better than a plastic PC mic

7. How do I know that? www.homebrewaudio.com vs www.homebrewaudio.com

8. 1.A microphone captures the sound 2.The sound is converted to ones and zeros (digital audio) by a soundcard/interface. 3.A recording program reads the digital audio, allowing you to edit, save, etc. www.homebrewaudio.com In a world…

9. 1. A microphone plugged directly into a computer, either via the sound card or a USB port 2. A microphone plugged into an interface 3-pin (XLR) cable  computer www.homebrewaudio.com Plus there’s mobile

10.  Fight the noise first ◦ Prevent as much getting recorded as possible  Use a cardioid microphone (tip #1)  Get close to the microphone (tip #2)  Then fight it again ◦ Record as loud as possible without clipping (tip #3)  “Crowds out” a lot of system noise  And again ◦ Use noise reduction tools to reduce the noise that got recorded (inevitable) (tip #4) www.homebrewaudio.com

11.  In a perfect world, you would have a great recording space where the room sound actually compliments the signal. ◦ These types of spaces are rare.  The second best option is to have a vocal isolation booth treated with materials designed to prevent absorb echoes, allowing you to record only the signal. ◦ Difficult to do right ◦ Expensive www.homebrewaudio.com

13.  We’re recording in bedrooms with lots of parallel surfaces echo-y sound.  Very common in even the best looking videos  Problem is worse in “talking-head” videos signal noise www.homebrewaudio.com

14.  Use a mic with a cardioid pickup pattern  Mouth close to the mic ◦ ~4 inches or so www.homebrewaudio.com Note: Talk into the correct side of a side-address mic!

15.  Record as loud as possible without clipping This is not good If you try to turn this up, you’ll be turning up the noise along with it! Aim for this Won’t have to turn this up much, if at all. MUCH better quality. Do this with gain control on interface and/or input level in software mixer Do this with gain control on interface and/or input level in software mixer www.homebrewaudio.com

16.  Some noise will always be recorded, especially with cheaper mics and converters  Use Noise Reduction in audio software www.homebrewaudio.com

17. 1.Using a cardioid mic 2.Getting close to the mic 3.Reducing/removing noise after it is recorded www.homebrewaudio.com

18.  Now we can address step #2 of recording basics, "sound is converted to ones and zeros (digital audio) by a soundcard/interface.“  Why is the $5 mic into a sound card not ideal? ◦ Small cheap mic is inaccurate ◦ Integrated sound card is cheap and noisy  So the best 1 st step is… www.homebrewaudio.com

19. The fastest and least expensive way to do this is: Built-In converters are better Avoid noisy motherboard www.homebrewaudio.com

20.  Small USB mics still subject to accuracy limitations ◦ Must work very hard to get “pro” audio, though it is still possible  I highly recommend the large USB Mics ◦ Much easier to reach “pro” level audio Samson Q1 Samson C01 Large diaphragm condenser www.homebrewaudio.com $49 $80 Blue Yeti $100
