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.
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.
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!
Zrtstr is tested to work under Windows and GNU/Linux. Probably works on OSX with no changes.
Binaries for the main platforms are provided in Releases.
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.
Here are the current problems and planned features:
- Dither thresholding in dB
- Variable default dither threshold based on bitdepth
- Add automatic tests
The project is open for contributions. Any help and/or critique is appreciated. Take a stab at the TODO list above.
