Pickup (or polar) pattern Omni – good for recording groups in a good room. Also great when put in the middle of a drum kit. Can be used as excellent vox mic. Example: Earthworks QTC1 Pickup (or polar) pattern Directional (Cardioid) – pickup pattern helps isolate the sound and avoid “bleeding” Usually used for VOX and close micing instruments Example: Shure SM58, AKG Perception 120 Pickup (or polar) pattern Bi-Directional (Figure 8) Known for a smooth sound. Common in the 30s and 40s. Often used with vocalists on each side of the mic. Example: RCA 44, Royer 122, AKG 414
3. And you’ve decided to add a personal touch to your work
4. And only your velvet smooth voice will work
5. Well, grasshopper, there’ll be some costs Kung Fu 1972 - 1975 David Carradine 1936 - 2009
6. Costs ??
7. Ah, grasshopper, I see the confused look on your face
8. Let’s us see if the language of tables will help to show you the path
9. The Voice Equipment & Software In-House Free $50 to $1000 Professional $100/hr 2-5 hrs per 30 min of narration Free
10. In-House ??
11. Ah, yes, grasshopper, always better to do the task yourself
13. <ul><li>Tech Info </li></ul><ul><li>Gear </li></ul><ul><li>Software </li></ul><ul><li>Narration Tips </li></ul>but there’ll be some learnin’ to do!
14. Technology is hard
15. It is not our way grasshopper, but the world is changing, so we adapt
16. Adapt ??
17. A short history of sound, may help you see the way
18. <ul><li>Very Short </li></ul>A Short History of Sound
19. In the beginning
20. there was Sound
21. and it was fine FOOD!
22. then came Analog Thomas Edison 1847 - 1931
23. and was hailed as good
24. so then Stereo came to us
25. and this was better
26. and so in the fullest of time
27. Digital was given on to us
28. and much rejoicing was had
29. but wonders did not cease
30. as mp3’s entered our world
31. and much sharing was had
32. and thus in the end,
33. it came on to us, to add sound
34. … to our presentations
35. thus greater understanding
36. … was had by all Warning Tech Stuff Incoming
37. So where to start ??? <ul><li>Helps to know more about sound </li></ul>
38. Analog vs. Digital <ul><li>When source is analog (tape, vinyl), </li></ul><ul><li>quality is lost as you take it to digital (computer) </li></ul><ul><li>Start digital, no losses until you encode down </li></ul>Bloomingdales 1904
39. Does Stereo Matter? <ul><li>Sure does - with 2 ears & 2 sides of the brain, it just sounds better </li></ul>
40. Stereo Perception <ul><li>It’s louder in the one ear compared to the other </li></ul><ul><li>(Volume differential) </li></ul>
41. <ul><li>It gets to one ear before the other </li></ul><ul><li>(Time arrival delta) </li></ul>Stereo Perception
42. So lets get small…
43. … and into the wave we go… 228 sec This is a wave file
44. … to the great below… 3.8 sec
45. … and down …. 0.25 sec
46. … and down we go… 0.06 sec
47. ..till we hit a data point 0.001 sec
48. Sound is Data How much, well that depends…
49. … on Sampling Rate… <ul><li>22 kHz – Radio </li></ul><ul><li>44.1 kHz – CD </li></ul><ul><li>96 kHz – DVD </li></ul>kHz = 1000 Samples per Second Higher rate, more data For voice..
50. … and Bit Depth <ul><li>8 bit - Radio </li></ul><ul><li>16 bit - CD </li></ul><ul><li>32 bit - DVD </li></ul>Higher depth, more data Establishes amplitude resolution I use this..
51. <ul><li>Carry the raw data as long as you can… </li></ul><ul><li>… then encode down as needed at the end </li></ul>Start High, End Low
52. The nicer the… … the better the sound you want
53. <ul><li>But in the end, sound must just be good enough… </li></ul>
54. Record & edit as a Wav <ul><li>Save as an mp3 </li></ul>
55. Wav vs. mp3 <ul><li>You give up some quality, </li></ul><ul><li>but get greatly reduced size </li></ul>
56. <ul><li>Wav = </li></ul><ul><li>Raw Sound </li></ul>What’s the Diff ? mp3 = Zip Files for Sound Drop off after 16kHz
57. People only hear so much
58. <ul><li>Most speech is in the 2 to 4 kHz range </li></ul><ul><li>Losing 16 kHz + on the encoding, not a big deal </li></ul>So people don’t miss it
59. mp3 Encoding Engines =< 192 Kb/sec >= 192 Kb/sec Built into commercial sound engineering software Shareware, Open Source http://lame.sourceforge.net/
60. File Size (mb) Bitrate (Kb/sec) 32 -Audible 64 - Vocals 192 - CD Lame FhG 356 - DVD Both good to 192
61. Bitrate (kb/sec) to use <ul><li>Uploading to 64 to 128 </li></ul><ul><li>Encoding to AVI 192 minimum </li></ul><ul><li>Encoding to FLV 96 to 128 </li></ul>Guidelines only
62. Ok, enough Tech
63. Hardware ??
64. No, grasshopper, not hardware like the stone hammer. You make me laugh, you do.
65. Into the Computer > > Soundcard Soundchip
66. Into the Computer > > Soundcard Soundchip Really get one, it’s worth it
67. Types of Mics <ul><li>Dynamic / moving coil mics </li></ul><ul><ul><li>Cheap </li></ul></ul><ul><li>Condenser mics </li></ul><ul><ul><li>More expensive and better </li></ul></ul><ul><ul><li>Require power & preamp </li></ul></ul>Cyber Acoustics AC-850 AKG Perception 120 Mic My Mic
69. Microphone Placement <ul><li>Close but not too close, Darth Vader breathing will not go over well </li></ul>
70. Stand & Echo Screen <ul><li>Softens the hard “p” and “b” </li></ul>Reduces noise due to vibration I use this.. and this..
71. USB Pre-Amp Instrument Input Gain Control Headphone Out Headphone Volume Control Phantom Power Switch USB Port Stereo Line Out Unbalanced Output Stereo Mic Input Instrument Input XLR Mic Input and this..
72. The Wires XLR Cable USB Cable
73. Set Both
74. Pick This
75. Then This
76. And Then This
77. Hit OK
78. And finally… This defines how loud the mic will be Too high, overclipping (Very Bad) Too Low, too quiet (Not good either)
83. USB PreAmp
85. XRL Cable
87. Windows Sound Figured Out PRICELESS
88. Is narrating any easier ?
89. Yes, grasshopper, but you will have to talk for it to work. Here are some guidelines.
90. Be consistent with phrases “ Don’t” or “Do Not” Try not. Do or do not. There is no try.
91. Avoid Slang <ul><li>Who is the audience ? </li></ul>So like this dude was totally not cool, as if….
92. Sound natural, don’t imitate another voice, use your own
93. Make a Script I do this always
94. Script Deviations <ul><li>Minimize, but do as needed to sound natural </li></ul>
95. Posture <ul><li>Get Comfortable… </li></ul>but not too…. Stand or Sit Straight – Let diaphragm expand fully
96. Avoid Noise
97. Sound Insulation http://voiceoveressentials.com/ Good for reducing noise in the recording
98. <ul><li>Morning, Noon or Night </li></ul>Our voices vary through the day
99. <ul><li>Just not a morning person when it comes to narration, or at least my voice isn’t ! </li></ul>I’m better in the afternoon
100. <ul><li>You’ll sound better while you narrate – Really! </li></ul>Smile and Be Happy
101. <ul><li>Lubricate the vocal cords, you’ll be working them hard </li></ul><ul><li>Water >> Soda or Milk </li></ul>
102. Record in a one sitting After all we are not stage actors or professionals are we ?
103. <ul><li>Also voices will vary from day to day </li></ul>
104. Slide 5 Put 5 sec gaps in as you go Easier to see where to save out later
105. <ul><li>Aim for 10 to 60 sec of narration per slide </li></ul>
106. <ul><li>Stuff happens – pause for a few sec, and keep going </li></ul>I’m good at this! Can always cut out the mistake(s) later
107. Recording with PPT Oxymoron
108. Use a real program for sound CoolEdit aka Adobe Audition
109. Settings In & Out <ul><li>Set these before recording </li></ul>USB PreAmp Soundcard
110. Start a New Recording My Settings
111. New Recording Pause Record Used mostly
112. Do a Sound Check
113. When recording DO NOT allow the volume level to exceed these lines
114. Else you get overclipping, and this is bad
115. Part 2 If overclipping, lower Windows sound input a bit and try again This control is sensitive and may take a few tries
116. One Mic – One Track - Mono Two Mic – Two Tracks - Stereo
117. But, but you said one mic I can’t afford two of them, I don’t even carry money! Dr. Who (10 th ) 2005 - 2010
118. No problem, grasshopper Follow these Simple Steps
119. Record the narration
120. Ctrl-A to Select Upper Track
121. Ctrl-C to Copy Upper Track
122. Select Lower Track
123. Ctrl-A to Select Lower Track
124. Ctrl-V to Copy to Lower Track
125. Look at that, Mono to Stereo (poor man’s style)
126. Save As Wav File
127. “ Post Production” …these terms seem alien to me, master
128. True, grasshopper, but nothing is ever prefect the first time
129. <ul><li>Narration always needs some fixing </li></ul>Clean Up on Aisle 4
130. Noise Reduction Highlight a section of a 5 sec gap
131. <ul><li>Get a profile from the 5 sec gap </li></ul>
132. <ul><li>Set the amount of Noise Reduction </li></ul>
133. <ul><li>And apply to the 5 sec gap </li></ul>
134. Then Select Entire Wave
135. <ul><li>Then apply the 5 sec profile to it </li></ul>
136. Careful, Grasshopper 40% Noise Reduction using 5 sec gap profile 40% Noise Reduction using entire wav profile
137. Silence Highlight a section And apply silence as needed
138. Click, Pop and Hiss Removal Usually this one
139. Overclipping This is bad
140. Lots of Overclipping Lower the input and retry Spend time on the sound check to avoid this
141. Some Overclipping I use this Use sparingly
142. Save each slide out as an mp3
143. Use a Topic – SlideXX.mp3 naming scheme Easier to attach sound files later To set encoding I use this
144. Normalizing <ul><li>Do after you have all the mp3’s saved out </li></ul><ul><li>Use mp3Gain – makes all mp3 have same loudness </li></ul>http://mp3gain.sourceforge.net/
145. Add Files
146. Do Track Analysis
147. Results of Track Analysis
148. Apply Track Gain
149. Now all tracks have same volume
150. Danger, Will Robinson, Danger <ul><li>Don’t over “clean” the WAV file </li></ul><ul><li>Been there, done that </li></ul>Lost in Space 1965 - 1968
151. So with this knowledge, I too may do YouTube, master
152. Perhaps, grasshopper, perhaps
153. PPT 2007 Sound
154. PPT 2003 Sound
155. Custom Animation <ul><li>But this is for a future presentation… </li></ul>Sound object on the time line
156. Go to Moving Pictures <ul><li>PPT with sound / custom timings </li></ul><ul><ul><li>Convert to Flash (YouTube) </li></ul></ul><ul><ul><li>Convert to Movie (AVI, DVD) </li></ul></ul>Camtasia ( www.techsmith.com )
157. PPT converted to Flash example http://tinyurl.com/bep8dh I did this
158. So grasshopper, what have you learned from this lesson today?
159. Patience in all things, master ??
160. Hmm, let’s review this lesson
162. Anyone can narrate and I mean anyone
163. But nothing is ….
164. So get the right gear with a decent soundcard
165. Plus the right software Any of these will do, they all have the same basic capabilities And get ….
166. Go to town with your voice
167. Add some spice into your PPT
168. Ah, I see master, anyone can do narrations for their work
169. Yes, grasshopper, almost anyone, but I think your path lies elsewhere
170. So this show be done…
171. … and The Fat Lady has NOT left the building ! Ella Fitzgerald 1917 - 1996
