15. Final Cleanup, ACX Check, and MP3 Export
Let's get our audiobook chapter out the door and on its way! ACX requires that our final MP3 file have a bit rate of 192kb/s (192,000 bits per second) or higher. Bit rate (or as Audacity calls it, Quality) is a reference to how much of the original sampled information we want to retain in our conversion to MP3. Remember, our original sample rate was 44.1kHz or 44,100 samples per second. That was an uncompressed, lossless WAV file. But now we have to convert it to a compressed, lossy MP3 file for streaming. Bit rate is referring to how much of the original sampled information we want to use as we convert it to MP3. Typically, the higher the bit rate (Quality), the better the reproduction. ACX requires a minimum bit rate of 192kb/s.After exporting our final MP3 file, I like to bring it back into Audacity and run ACX Check one last time before uploading it to ACX. You'll find a link to the ACX Audio Submission Requirements in the Resources folder.
