voice does not need much data. mono at 64 kbps and 22 khz sounds clear and is about 0.5 mb per minute, so a one hour interview is around 29 mb, small enough for most email services and cloud links.
quiet recordings improve a lot with a few db of gain, which this preset adds. do not push far past +6 db, since a loud peak can distort. add a fade to hide the click at the start and end of a trimmed clip. for podcasts that include music, use 128 kbps stereo instead.
