CLI

Engine Sound Generator 1.3.0https://github.com/DasEtwas/GUI Application used to generate purely synthetic engine sounds with advanced options in real-time, written in Rust.It features real-time recording of the engine, a CLI, automatic crossfading to create seamless loops in the CLI,realtime frequency domain display through FFT, and preset saving/loading capabilities.USAGE:    enginesound [FLAGS] [OPTIONS]FLAGS:        --help        Prints help information    -h, --headless    CLI mode without GUI or audio playback    -V, --version     Prints version informationOPTIONS:    -c, --config <config>              Sets the input file to load as an engine config    -f, --crossfade <crossfade>        Crossfades the recording in the middle end-to-start to create a seamless loop,                                       although adjusting the recording's length to the rpm is recommended. The value                                       sets the size of the crossfade, where the final output is decreased in length by                                       crossfade_time/2.    -o, --output <output_file>         Sets the output .wav file path    -l, --length <reclen>              Sets the time to record in seconds. The formula for the recommended time to                                       record to get a seamless loop is as follows:                                       let wavelength = 120.0 / rpm;                                       let crossfade = wavelength * 2.0;                                       let reclen = audio_length + crossfade / 2.0;    -r, --rpm <rpm>                    Engine RPM    -q, --samplerate <samplerate>      Generator sample rate [default: 48000]    -v, --volume <volume>              Sets the master volume [default: 0.1]    -w, --warmup_time <warmup_time>    Sets the time to wait in seconds before recording
