ggwave

Usage: ./bin/ggwave-to-file [-vN] [-sN] [-pN]
    -vN - output volume, N in (0, 100], (default: 50)
    -sN - output sample rate, N in [1024, 48000], (default: 48000)
    -pN - select the transmission protocol (default: 1)

    Available protocols:
      0 - Normal
      1 - Fast
      2 - Fastest
      3 - [U] Normal
      4 - [U] Fast
      5 - [U] Fastest

Examples

Generate waveform with default parameters

echo "Hello world!" | ./bin/ggwave-to-file > example.wav

Generate waveform at 24 kHz sample rate

echo "Hello world!" | ./bin/ggwave-to-file -s24000 > example.wav

Generate ultrasound waveform using the [U] Fast protocol

echo "Hello world!" | ./bin/ggwave-to-file -p4 > example.wav

HTTP service

Based on this tool, there is an HTTP service available on the following link:

https://ggwave-to-file.ggerganov.com/

You can use it to query audio waveforms by specifying the text message as a GET parameter to the HTTP request. Here are a few examples:

terminal

# audible example
curl -sS 'https://ggwave-to-file.ggerganov.com/?m=Hello world!' --output hello.wav

# ultrasound example
curl -sS 'https://ggwave-to-file.ggerganov.com/?m=Hello world!&p=4' --output hello.wav
