“We have been using acWAVE batch converter for about three years, and it works great! Since we convert over 600 audio files a day, it was very important to us to be efficient.  acWAVE has saved us about four hours of work per day over the previous method of conversion that we used.”
Programmer, Medical Transcription Company, St. Louis, MO

"I just wanted you to know how happy we are to have discovered your product, acWAVE!  We have been using your product since about 2005 to do automatic batch audio conversions for our ASP platforms, mydigitalvoice and Since installing your product, acWAVE we have processed over 1,000,000 conversions (on one server alone) without a problem. In fact, the first time we had to call for technical support was when we replaced a server and we needed a license key re-issued! Your technician was patient, listened to our problem, and reissued the license promptly without issue.  Thank you for such a great product!"
Scott D. Stuckey, ASP Product Manager,, Voice Systems, Inc., Tampa, FL

"We have used acWAVE software for about 7 years now and have been completely satisfied with it.  I would recommend your product to anyone.  Thanks."
