EXPLICACIN DE OBJETOS DEL CODIGO:

En una GUIDE se genera la funcin mtodo del objeto que voy a codificar, luego de haberlo creado manualmente, es decir la programacin es independiente. No va depender de cuantos objetos tenga en un momento sino que conforme vaya necesitando masobjetos los crear , programar a mi aplicacin.

Los objetos que cre son los siguiente:1. function edit1_CreateFcn(hObject, eventdata, handles); es un Edit Text donde almaceno el tiempo de adquisicion de sonido.2. function pushbutton1_Callback(hObject, eventdata, handles); es un Pushbutton que me permite grabar sonidos.3. function pushbutton2_Callback(hObject, eventdata, handles); es un Pushbutton que me permite detener la grabacion de sonidos.4. function pushbutton3_Callback(hObject, eventdata, handles); es un Pushbutton que me permite reproducir los sonidos que e grabado.5. function volumen_Callback(hObject, eventdata, handles);es un pushbuttonque me permite manejar el volumen de sonido cuando reprodusco una cancion format

.wav.6. function play_Callback(hObject, eventdata, handles); es un pushbutton que me permite reproducer musica con format .wav.7. function mute_Callback(hObject, eventdata, handles); es un pushbutton que me permite quitar el sonido cuando estoy reproduciendo un cancion con format .wav.8. function openfiles_Callback(hObject, eventdata, handles); es un pushbutton que me permite abrir el directorio donde se encuntran mis archives para luegoreproducir una cancin.9. function radiobutton1_Callback(hObject, eventdata, handles); es un radiobutton que me permite invertir la seal usando el commando flipud.10. function radiobutton2_Callback(hObject, eventdata, handles); es un radiobutton que me permite crear eco al canal izquierdo de la seal de audio.

11. function radiobutton3_Callback(hObject, eventdata, handles); es un radiobutton que me permite crear un pre eco a mi seal de audio grabada.12. function radiobutton4_Callback(hObject, eventdata, handles): es un radiobutton que me permite crear eco recursivo a mi seal de audio grabada.13. function Reproducir_Efecto_Callback(hObject, eventdata, handles); es unpushbutton que me permite reproducir los efectos que le correponde a cada radiobutton.14. function zoom1_Callback(hObject, eventdata, handles); es un pushbutton que me permite hacer uso del zoom en mis graficas de seal de audio.15. function figure1_CloseRequestFcn(hObject, eventdata, handles); aqu aparece un mensaje si desea salir del programa o continuar.
