- ffmpeg now needed for both decoding audio and filtering
- It is not included (install however you like!), but will cause errors if it is missing
- Bandpass logic now using a complex filter in ffmpeg instead of sox
- Decode also using ffmpeg, which should support more audio encodings than sox
- Change to use ffmpeg motivated by it being more common and having ready static builds
- No more sox dependency
- First release!
- Uses sox and multimon-ng and some DSP code to detect attention and fsk tones.
- Attempts to detect even if the tones are incomplete, low energy, or mixed.
- Includes a sensitive mode which gets false positives on some audio (e.g. music)
