PASS: 16-verify-tx-consistent.test FAIL: 17-verify-tx-consistent-float.test The FAIL is due inconsistency in the .wav header (only for floats) constructed by libsndfile -- its different every wall-clock second. Even just a bare header (no audio samples) shows the effect: minimodem --float-samples --tx 1000 -f /tmp/xx.wav </dev/null sum -r /tmp/xx.wav sleep 1 minimodem --float-samples --tx 1000 -f /tmp/xx.wav </dev/null sum -r /tmp/xx.wav This might also relate to: https://github.com/kamalmostafa/minimodem/issues/24
minimodem - general-purpose software audio FSK modem Copyright (C) 2011-2016 Kamal Mostafa <kamal@whence.com> Minimodem is a command-line program which decodes (or generates) audio modem tones at any specified baud rate, using various framing protocols. It acts a general-purpose software FSK modem, and includes support for various standard FSK protocols such as Bell103, Bell202, RTTY, TTY/TDD, NOAA SAME, and Caller-ID. Minimodem can play and capture audio modem tones in real-time via the system audio device, or in batched mode via audio files. Minimodem can be used to transfer data between nearby computers using an audio cable (or just via sound waves), or between remote computers using radio, telephone, or another audio communications medium.
