ok , here we go
first off you want to select the file that you want to convert by clicking on file > open > folder > file >open , just like i have done in these 2 pictures
next you want to select the section of the song you want to covert to make your ringtone , i usually make my tones about 25 sec. long , otherwise the file is too big , and i think it will only play up to 29 sec. anyways
you can select the section of the song by left clicking on the waveform where you want the tone to start and holding down the left button drag it to the end of the tone , at the bottom right , you can see how long your selection is in mins. secs.
when you get to the end let off the button , then right click your selection and copy to new like i have done in this picture
the next thing you want to do is , convert the sample , you can do this by clicking the button ive shown in the picture with the red arrow , convert with these settings sample rate=8000 channel=mono resolution=8bit then click ok
you can see these things on the following picture
next you want to save your selection , but you want to save it as a .wav file so what you do know is click the button im showing with the red arrow in this next picture , then choose the file where you would like the folder to be saved to , next change the name of the file if you need to ( i think the file name can only be up too 20 characters) then go to the drop down menu titled-save as type and select ACM Waveform then click ok , you can see these actions on the pictures ive provided below
and now you are done , now just use your loading program to install them on your phone , i use iden webjal
goodluck!!!!!!
