Audacity Workflow

Audacity Workflow
  1. Narrate in Adobe Prem. Elements.
  2. If importing use AIF files from Adobe Prem. Elem. skip to 8.
  3. Plug in microphone. Start Audacity.
  4. Set mic to AT2020USB
  5. Use "windows direct sound"
  6. 0.0 dB is highest level for digital audio.
  7. Actually -2.0 dB would be best.
  8. First "Noise Removal". Start recording just the ambient noise.
  9. Apply "normalization."
  10. "Equalization", AM Radio profile, use flatten
  11. "Compression". Make softer louder. and Louder softer.
  12. "Normalize again".
  13. Reduce peaks with "amplify"
  14. Kill breath with "silence"
  15. Adjust gain of loud parts with "Amplify"
  16. Save as "wav" file

Files to import
The main formats  are AIFF, AU, FLAC, MP2, MP3, OGG Vorbis and WAV. On Mac OS X, Audacity as shipped can also import Apple formats like M4A (AAC) and MOV.


AVI vs MOV?

MOV is a newer format. MOV supports subtitles.

Lesson Plan For Grade 3, Quotition Division Research

Understanding quotition division is a prerequisite to making progress in problem solving and algebra. Students who do not have an intuitive feel for quotition must rely on processes. When they get to word problems, they ask "how do I set up the problem"? As students age their memory for unrelated processes gets weaker.


This is a bibliography for "Lesson Plan For Grade 3, Quotition Division"


Making Sense of Partitive and Quotitive Division
about 25% of teachers could make sense of 8 / (1/2) or 8/0.5.

What is division?
Reference 
Wikipedia  and Mathematics Stack Exchange


Division can written as: a/b = c.
a is the dividend.
b is the divisor.
c is the quotient.

Division can be expressed as:
1) Partition division
2) Quotition division


Partition Division

6 / 2 = ?
Divide 6 into 2 groups.
How many are in each group?

(Get the answer! Show 6 tiles. Make 2 equal groups. Count how many there are in a group.)

6/2 = 3

Quotition Division

6/2 = ?

Divide 6 into groups of 2.
How many groups are there?

(Get the answer! Show 6 tiles. Make groups of 2 tiles. Count how many groups.)

6/2 = 3

The Money of Climate Change Denial

The Money of Climate Change Denial

According to Wikipedia under the heading "Climate Change Denial" between 2002 and 2010 $120 million was donated to "Donors Trust and Donors Capital Fund" that was distributed to the denial effort.

120 / 8 = $15 million per year.

Math in the News: Marco Rubio’s tax-cut plan

From Nov. 8 Huffington Post:

  • Would reduce federal revenue by 12 Trillion Dollars over the next ten years.
  • Under current policies the federal tax revenue would be 42 Trillion Dollars.
Marco Rubio's plan would result in a 12 / 42 = 29% or about 30% decrease in tax revenue.
