I was playing around with audicity app today on my computer. In that app I was able to change my voice to Death Note L's Voice by overlapping multiple audiotracks at extreme pitches.
This project is an attempt to reproduce the same with FFMPEG and rust.
cargo build
cargo run ../input.m4a . # input file and output path
Once the run is complete you can able to see out.mp3 being generated by the binary. Which has your L's voice modulation.
./lsplitter test.mp4
# will create morphed video as test-convert.mp4
RUST_LOG=debug cargo run <in> <out>
To run in debug mode.
