Sound File Editing

feature author: Paul Halliday

All of the sounds used in the Beech 1900D simulator are binary sound data files stored in Microsoft’s WAVE format. These data files consist of digital samplings created by either recording a live source discussed earlier, or by synthesizing them using a sound file editor. Normal editing activities can include the following. 

• Trimming unwanted noise, clicks, and pops out of the data.

• Generating a sample using a tone generator.

• Converting from one format to another.

• Converting from Mono to Stereo or vice versa.

• Determining the size of the sample (8 or 16 bits).

• Cutting and pasting.

• Using Fast Fourier Transforms to isolate and filter particular sound segments within a sound.

• Matching the start and end of a sample that is going to be looped.

It is not the intent here to go into a sound file editing session. Proper treatment of such a subject would be better done in another article.

SimPhonics does not include a sound editor when delivering its systems. They recommend using Adobe Audition.
