write a C++ program that reads three numbers from the file infile.dat (you create it yourselves), sums the numbers, and writes the sum to the file outfile.dat.

For this assignment you will create an audio effects and analysis tool. Your program will need to have a Graphical User Interface (GUI) menu with the following functionality: Choose a File. This menu item will allow the user to enter exact name of audio file to be read into the program. The file has to be in.wav format. The audio vector and sampling frequency (Fs) from this module will be used for the remaining features of this program. 1. 2. Play the audio vector. Echo effect.Create a function that will add an echo effect to the audio signal. The function should take in the sound vector, sampling frequency, delay in seconds, and echo amplitude. The function should return a vector containing the echoed sound. 3. sounVecEchosoundEcho (soundVec, Fs, delay, echoGain) Steps you should follow when designing your function: a. Take in the audio vector and sampling frequency, delay and echo gain. b. Convert the delay in seconds to number of samples delaySamples- Fs * delay; Figure out a way to add a delayed version of the signal vector to the original sound vector. delaySamples tells you how many elements the offset needs to be c. d. Play the new version of your sound vector. Compress. Create a function that takes in the sound vector and compression ratio. The function should compress the file by removing vector elements based on the compression ratio. (ie. if you the compression ratio is 3, keep only every third element.) The function should return the compressed vector 4. compSoundVec -compress (soundvec, compression ratio)
