zrtstr

Third Hemisphere Studio tooling

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 the left channel of the input file, writes the converted file in the same location with the -MONO suffix in the name.

Usage

Provide zrtstr with an input file as an argument, or run it from a directory full of target WAV files.

Full help available on --help switch.

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 (and higher than the threshold given in --dither mode) than file considered true-stereo and program tries to write a mono copy.

Defaults include a reasonable dither threshold value, for strict checking set it to zero with -d 0!

Installation

Rearchiver is tested to work under Windows and GNU/Linux. Probably works on OSX with no changes.

Download

Binaries for the main platforms are provided in Releases.

How to build

Developed on nightly Rust, as stable makes getting samples for multiple channels a bit more problematic for hound.

Built using these wonderful crates: Hound, Clap, pbr.

To build the program, download the source code and run:

$ cargo build --release

and the executable will be in target/release/zrtstr.

TODO

Here are the current problems and planned features:

• Dither thresholding in dB
• Variable default dither threshold based on bitdepth
• Add automatic tests

Contributing

The project is open for contributions. Any help and/or critique is appreciated. Take a stab at the TODO list above.
