I have been tasked with looking into a bit of software that will allow phone calls (.wav files) to be edited to remove/bleep out confidential information within the file. This edited version has to be sent on to an external company and they can only access the edited version. This edited file cannot be modified in any way to get back to the original call/.wav file by the external company. Is this something that Audacity is capable of doing? Sorry, not up to speed on the whole redacting voice calls.
Yes, because Audacity is a destructive editor - and anyway you will be exporting an audio file (WAV, MP3 etc.) which is rendered on export.
There are a few non-destructive realtime effects, but you probably won’t need or want to use those - but the render on export would deal with that anyway.
Thank for you the info. This is all new to me. To use Audacity for this purpose would it be a free product or would i need to look into purchasing a licence?
