In this section of the course we talk specifically about ACX audiobook requirements. This short overview video of section two introduces the ACX requirements for each of the following:

• Room Tone
• Noise Floor
• File Length
• Sample Rates
• Bit Depth
• RMS Loudness

I introduce each of these terms to you here and define them and I'll show you where to set the ones that can be set in advance in Audacity as we move through this section. We'll return to these terms throughout this course where applicable. You'll find a link below to ACX's Audio Terminology Glossary.
