Command line application for checking WAV-files for identical channels, detecting faux-stereo files generated by some audio-editing software and DAWs (such as old versions of Cubase). Outputs a true-mono WAV file on detection of faux-stereo. Takes left channel of the input file, writes in the same location with -MONO suffix in file name.
Developed using these wonderful crates:
Basically, provide zrtstr with input file as an argument, or run it from a directory full of target WAV files.

Latest Windows binaries are luckily provided in Releases via Appveyor.
How does it work?
Zrtstr reads interleaved channel samples from a target stereo file one by one and compares left and right samples. If the difference is present (or higher than the threshold given in
--dither mode) than file considered true-stereo and program tries to write a mono copy.
How to build
Developed on Rust Nightly, but should build with stable or beta as well.
To build the code, run:
$ cargo build --release
and the executable will be in
Here are the current problems and planned features:
- Float support: Add writing support for IEEE Float files (upstream-dependent)
- Add automatic tests
This is an enthusiast project, so any help and/or critique will be much appreciated.
