Voice files are recorded professionally using digital recording methods for the highest quality possible.  Each finished recording is processed to achieve a high quality recording for your project.  The finished product can be sent to you in wave files or MP3 on CD, or e-mailed to you using MP3.  Your music can be added, or I can arrange your purchase of music that can be added to your project.  Job turnaround is quick.....what else would you expect?
