#dynamic eq

This tutorial wanted me to generate my own sound effect for use in a radio play i.e. the sound of wind in trees. To start created an audio track in Adobe Audition and selected Generate>Noise.

I decided to create some brown noise in mono format.

To create the sound of wind in trees I decided to use an amplitude envelope, selecting Effects>Amplitude>Envelopes, I could then start to mess around with the amplitude at different parts of the brown noise to make the sound more realistic.

The screenshot shows how I can manipulate the amplitude of the waveform, and by selecting Spline Curves I could make the amplitude less jagged in the highest and lowest of the envelope.

I then continued to make the sound more realistic through putting on a graphic EQ (boosting the high frequencies, Effects>Filters>Graphic Equaliser) and also putting a long reverb tail on the waveform (Effects>Delay>Full Reverb).  The Screenshot above shows how I opted for a reverb preset named Ghost Whispers.

  The Next sound effect I decided to make was a sort of alien calling. I firstly created some tones shown below. Generate>Tones.  I went for a bi-tonal sound I thought this was most alien sounding.

  I then decided to put a dynamic EQ on the tones so as to create a sense of movement. Effects>Filters>Dynamic EQ.

After implementing these changes, this is what my waveform looked like.
