Quality Reqirements
Your sample must meet certain quality requirements, some of which are affected by the settings you select before recording, and others by how the sample is edited in post production. Note that many DAWs (including Audacity) automatically record in .wav format.
Before starting a recording, set parameters to:
- Bit Rate: 16bit
- Sample Rate: 44100 Hz (aka 44.1 kHz) or better.
Editing/Post production:
- It’s a good idea to save a draft of your work before you make any changes!
- Each file must:
- Be between -23dB and -18dB RMS.
- Have a peak value no higher than -3dB.
- Have a noise floor no higher than -60dB RMS.
>>>To format your recording, Audacity has a step by step guide to Audioook Mastering that is full of very detailed information to help your sample meet the criteria.
Here is a helpful tutorial video about editing to demonstrate how to meet these requirements in ACX.
You can also download a free ACX Check Plug-in to double check your work (here is a link for how to install plugins).
