Podcasters taking advantage of the unlimited mp3 file storage of the Black Talk Radio Network have one limitation. All podcasts uploaded to the servers have a 99MB limit per file. You have unlimited uploads and storage as long as each individual file is 99MB and below.
For digital radio broadcasters saving their mp3 files above 99MB there are plenty of audio editing software on the web but for the quickest conversion of audio, Format Factory is hard to beat for those using Windows based OS and its free!
FormatFactory is an ad-supported freeware multimedia converter that can convert video, audio, and picture files. It is also capable of ripping DVDs and CDs to other file formats, as well as creating .iso images. It can also join multiple video files together into one.
