Re: Manipulating Decibels

So we're in 'Secret Aural Teachings" territory and it's perfectly possible and expected for ACX to reject weeks of finished product. Not helpful. Perhaps a bit harsh. An alternative view: ACX are in the business of acquiring audio books for commercial publication. Customers that purchase the a...

Re: Sound quality reduced while using "Noise Removal"

Re: Audacity locks up when editing

Re: Manipulating Decibels

What they definitely don't want is: "talk, talk, talk | (absolute silence) | talk, talk, talk.." because that is completely unnatural and is more distracting for the listener than having a small amount of noise ("room tone"). I don't remember seeing that in the ACX Requirements ...

Behringer offer various software bundles, depending on the product bought. Mostly these are freeware though some bundles include special deals that they have negotiated with the software producers. The software items offered are not necessarily compatible with each other and we have no control over ...
