Sound Effects:
We have created some sound effects listed below:
1: Echo
2: Delay
3: Multiple delays
4: Multiple echoes
5: Fade in
6: Fade out
1:ECHO:
The Phenomenon produced when a sound reflects from any obstacle delayed by 100 ms.Or in other words, repetition of a sound by reflection of sound waves from a surface. Echo rises in Communication systems, when signals encounter a mismatch in impedance.
Figure:Echo Sound Effect
ALGORITHM:
We are reading a sound clip from a file into a vector, then we produced the delayed version of the sound (delaying it by 100 ms),then we add the two vectors obtaining the resultant echoed sound clip.
Figure: Graphical View of Echo Sound Effect.
2: MULTIPLE DELAYS:
When we add up a sound clip with itself each delayed by different factor,the resultant is multiple delayed sound effect.
Figure: Multiple Echo Sound Effects.
ALGORITHM:
A) Read a sound clip from a file
B) take input from user number of walls , Nwalls.
C) Input distance of each wall into Distance vector
D) Calculate delay of each reflected signal into delays vector.
E) Produce the delayed version of original sound by delaying it by delays[i]
F) Sum up the all delayed vectors. The resultant is multiple delayed signal.
