Bash script that utilises SoX to batch process audiobooks for ACX Audio Submission, Author's Republic, Findaway Voices, etc.
The script ensures that the audio files satisfy the following requirenments:
- Peak values no higher than -3dB.
- RMS level between -23dB and -18dB.
- 44.1kHz sample rate.
- Mono channel configuration.
- 0.5 - 1.0 seconds of room tone at the beginning of the file.
- 1.0 - 5.0 seconds of room tone at the end of the file.
Note: The script accepts and outputs *.wav files. Conversion to 192kbps CBR MP3 must be handled separately.
