I am moving a system's dependency on Sox to Ecasound and am not sure exactly how to go about increasing volume a set amount of decibels. To explain, we have xml templates where effects are applied to the audio and the current sox based system requires a value in decibels. I have tried taking the decibel number, multiplying it by 100 and giving that as a value to '-eva'. However, my new system produces clipped and loud audio whereas the current legacy system is smooth and much quieter. What is a good algorithm I can implement? -- Jason Galyon Silver Screen Tele-Reality, Inc. http://www.sister.tv | http://www.videocarlot.tv Phone: 972-855-3500 | Fax: 413-778-2146 |
