Problem Description View the sound wave produced from a wav file Apply different modulations to the wave file Hear the effect of the various modulations and view how the sound wave is affected
3
File Input Use the “Load File” Must be a.wav file type
4
Filters GUI features a low and high filter Low – suppresses values higher than the value specified High – suppresses values lower than the value specified
5
Other modulations User can select to play the wav file backwards User can also select a play speed User can reduce speed up to 2.5 times and increase speed up to 2 time
7
Click on “Load File” to select file to input “Play”, “Pause”, “Stop”, “Resume” Apply filters Speed multipler?
8
Play Backwards? “Play”, “Pause”, “Stop”, “Resume” Repeat
9
Applications Could be applied to other forms of wave data such as Brain waves Analyzing recordings from various animals Selection for certain frequencies of sound
10
Challenges Learning Matlab audio processing Plotting the correct filter Play, Pause, etc. Upper and lower ranged filter
11
Future Work Upper and lower ranged filter Comparing multiple wave signals Adjusting code to compensate for pitch changes as a result of changes in speed
