Quality?

Twitter: @Tibbon12

Page 13: Podcamp Pittsburgh 3- Audio Techniques

Quality

• Clear

• Noise-free

• Natural

• No distractions

Twitter: @Tibbon13

Page 14: Podcamp Pittsburgh 3- Audio Techniques

Examples of Quality

• Howard Stern Show

• NPR

• TED Talks

• Most Revision3 shows

Twitter: @Tibbon14

Page 15: Podcamp Pittsburgh 3- Audio Techniques

Examples of Poor Quality

• Totally Rad Show

• Problems:

• Boomy

• Too much room sound

• Distracting noise

• Sounds like recorded in a garage

Twitter: @Tibbon15

Where do consumers listen?

• Mostly on headphones (65%)

• Often on laptops (15%)

• Sometimes on full range speakers (~10%)

• Occasionally in the car (~10%)

• All numbers are estimates*

1) Quality Mics last a Lifetime

• Mostly Condenser Mics

• Dynamic Mics to Consider; SM-7B, RE-20

• Some bargains, but you get what you pay for

• Beware of cheap ‘tube’ mics

• Use Proper Technique, be mindful of proximity effect

Twitter: @Tibbon17

Page 18: Podcamp Pittsburgh 3- Audio Techniques

1a) “Other” Mics

• Shotgun Mics- Capture sound from a distance

• Lavilier (Lav) mics- Often with wireless packs

• Combine well together

Shotgun Mics19

Page 20: Podcamp Pittsburgh 3- Audio Techniques

• Optional! Software works too

• Control Dynamics, Makes Sound Fuller

• Does it right the first time, better workflow

• As a downside, difficult to use in the field

2) Use a Hardware Compressor

Twitter: @Tibbon20

Page 21: Podcamp Pittsburgh 3- Audio Techniques

2a) Channel Strips are cool

• Combine hardware preamp, EQ and compressor

• All-in-one package

• Great values, again you get what you pay for

Twitter: @Tibbon21

Page 22: Podcamp Pittsburgh 3- Audio Techniques

2b) Lunchboxes are cooler!

• Modular chassis that allow you to insert module units such as a preamp, compressor, eq, etc.

• Power connections/Chassis all in one

• Save money, space, and ease of portability

• Downside: No low end setup. Expensive but great value

Twitter: @Tibbon22

Page 23: Podcamp Pittsburgh 3- Audio Techniques

3) Preamps Matter• Preamps amplify the signal level of the

microphone to line level

• Built in preamps are sometimes fine, but high quality external preamps are great!

• All do the same thing, but like different methods of heating food all yield slightly different results

• Don’t go overboard

• In short: Most sound cards are insufficient

Twitter: @Tibbon23

4) Treat a room

• Acoustic treatment doesn’t make a room quieter or eliminate noise.

• Do not over-deaden

• Listen to this room.

• Close Mic’ing technique will help overcome some room issues

Takeaway #2:Two cool forums:

Harmony-Central (http://acapella.harmony-central.com)

5) Workflow is King

• Use a Patchbay!!!

• Do it right the first time

• Have extras of common items onhand (microphones, cables, pop filters, mic stands, headphones)

• Software only matters for workflow

• Keep your workspace clean

Twitter: @Tibbon26

Page 27: Podcamp Pittsburgh 3- Audio Techniques

6) Get a second set of Monitors

• One ‘full range’ set (Mackie, Genelec, Dynaudio, Yamaha)

• One ‘consumer’ set (NS-10, Auratone, Computer speakers)

• One high quality set of headphones, use while recording.

• Monitor controller/switch, headphone distribution

Twitter: @Tibbon27

Page 28: Podcamp Pittsburgh 3- Audio Techniques

7) Use Popfilters

• Helps with spacing from the microphone

• Helps with Plosives

• Clean them after sessions

• The metal ones work better (Inside tip: can be found cheap if you look around)

Twitter: @Tibbon28

Page 29: Podcamp Pittsburgh 3- Audio Techniques

8) Do Not Overdo Anything

• Excessive level line gain (normally means bad gain staging)

• Never Over-EQ (generally indicative of another problem)

• Excessive gating and compression also is bad.

• If anything is turned all the way up, you’re likely doing something wrong

Twitter: @Tibbon29

Page 30: Podcamp Pittsburgh 3- Audio Techniques

9) Use Room Tone

• Record room tone with all mics open, but no audio for 45 seconds

• When you cut out a mic, replace it with its room tone.

• Do not “Gate” audio. It makes things sound choppy. Replace with roomtone if you do this

• Use Noise Reduction only if needed. Quiet the room, not the recording

Twitter: @Tibbon30

Page 31: Podcamp Pittsburgh 3- Audio Techniques

10) Mix into a compressor

• Use a high threshold, low gain makeup, fast attack, slow release, high ratio compressor (20:1) to mix into

• You can even use two compressors (one more as a high ratio limiter, one as a low ratio compressor)

• There are some good plugins for this, such as the Sony Oxford Inflator or the L2. Just don’t overuse it

Twitter: @Tibbon31

Page 32: Podcamp Pittsburgh 3- Audio Techniques

11) Don’t Re-Compress Mastered Audio

• When flying in audio for intros, do not re-compress/limit/eq the pre-mastered audio

• It’s like cooking your food twice and simply makes it sound bad

• This applies specifically to the compressors mentioned in step 10!

Twitter: @Tibbon32

12) Find a good Audio Equipment Dealer!

• Allows borrows/returns easily and without issues

• Provides helpful problem solving

• Truthful and doesn’t oversell

• All equipment costs the same; Do not shop on price!

Twitter: @Tibbon33

Page 34: Podcamp Pittsburgh 3- Audio Techniques

Do Not:

• Clip the signal

• Record from a built in computer/camera microphone

• Record unprepared
