audio-program-generator 1.0.1

Create an audio program from a text file containing English sentences

apg (audio_program_generator)

Generates an audio program from a text file containing English sentences

Prerequisites

• Some relatively recent version of Python (3.7+)
• FFMPEG with at least the ability to read mp3s and wavs, and write mp3s

Description:

apg.py: Generate audio program of spoken phrases, with optional background sound file mixed in.

User populates a semicolon-separated text file with plain-text phrases, each followed by an inter-phrase duration. Each line of the file is comprised of:

• one phrase to be spoken
• a semicolon
• a silence duration (specified in seconds)

The script generates and saves a single MP3 file. The base name of the MP3 file is the same as the specified input file. So, for example, if the script is given input file "phrases.txt", the output file will be "phrases.mp3".

The "mix" command is used to mix in background sounds. This command takes an extra parameter, the path/filename of a sound file to be mixed in with the speech file generated from the phrase file. If the sound file is shorter in duration than the generated speech file, it will be looped. If it is longer, it will be truncated. The resulting background sound (looped or not) will be faded in and out to ensure a smooth transition. Currently, only .wav files are supported as inputs.

Usage:

apg [options] <phrase_file>
apg [options] mix <phrase_file> <sound_file>
apg -V --version
apg -h --help

Options:

-a --attenuation LEVEL  Set attenuation level of background file (non-
                        negative number, indicating dB attenuation).
-d --debug              Print debug statements to console.
-V --version            Show version.
-h --help               Show this screen.

Commands:

mix                     Mix files

Arguments:

phrase_file             Name of semicolon-separated text file containing
                        phrases and silence durations. Do not include
                        commas in this file.
sound_file              A file to be mixed into the generated program
                        file. Useful for background music/sounds. Must
                        be in .wav format.

Example <phrase_file> format:

Phrase One;2
Phrase Two;5
Phrase Three;0
