How can I export an ogg or FLAC file from adobe Audition? is there a plugin? If so, how do I install it, both on Mac and Windows? preferably looking for an all in one solution for simplicity
I haven't used Audition myself in years so I don't know if there is any plugin to do this, but even if there isn't, the classic workflow is to export to .wav or .aiff, and then use the converter of your choice to convert that to Ogg Vorbis or FLAC.
This will work for any tool that records audio, not just Audition.
