Audio adjustmet

Currently I am at home sorting out some of the link music for the documentary. Due to copy right laws we cannot use popular music. However there is a loop whole if the songs are remixed. So the group decided that this is an appropriate thing to do.

I'm using the software called 'audacity' to make this possible.

Firstly I have tried to increase the speed of the audio by 4.176% . this worked well. Any more than this and the song starts to distort.

I tried to put an Echo in place however this did not work the delay time (in seconds) 1.000000 along with the Delay factor of 0.50000 distorted the song making it hard to hear and wave length impossible to read unless zoomed into at a high percentage.

Next i adjusted the pitch of the track from F down to E. semitones (half notes) of -0.89. The frequency (in HZ) is from 2756.250 - 2618.438. The percent change was -5.

Lastly i looked at the tempo (tempo with out changing pitch). Firstly i thought due to the genera along with the documentary segment it would work well speed up. So put in place a percent change of 4.76. However we wanted to see if a decrease would also work just as well. I tried it by a -6% however with the other alterations sounded sloppy. Or to put in colloquially like a drunk person slurring there words. Which is not the effect one was looking for. I decided in the end to leave it at a -2% change.

Now the basics have been changed to give this segment of music a youthful and original feel to look at factors such as the 'wahwah' and the 'Phaser' effect and so on to see if any of these were appropriate. The 'whawah' effect did not work well, it distorted the music and created an I'm balance with the speakers. So ultimately used the other effect.

Next I adjusted the base to a frequency of 50 (Hz) and a boost (dB) 8. Anymore than this the music distorts and hurts the ears.

From point 0.0 where the audio starts on the stereo track bar I introduced a 'fade in' to the point 3.0. However this took away impact from the start and therefore would not impact the documentary in the way necessary.
Next i used the 'Envelope tool' to adjust wave size.

The segment of music is 28seconds long. This can be edited down on the apple mac computers to fit the documentary. Audio levels can be adjusted to when the presenter speaks, and fade outs can be introduced.

The images below show how the audio was adjusted:


Now just need to add this to the documentary.
