Program to check if stereo wav files have identical channels (faux-stereo) and convert them to mono.

Last update: Nov 6, 2022

Overview

zrtstr

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:

Hound, Clap, pbr

Usage

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

Full help available on --help switch.

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 target/release/zrtstr.

TODO

Here are the current problems and planned features:

Float support: Add writing support for IEEE Float files (upstream-dependent)
Add automatic tests

Contributing

This is an enthusiast project, so any help and/or critique will be much appreciated.

Compilation fails because of an outdated version of pbr

PBR fails to compile when building zrtstr due to this error:

error[E0283]: type annotations required: cannot resolve `std::string::String: std::convert::AsRef<_>`
   --> /Users/basta/.cargo/git/checkouts/pb-06f1c94bfc11587f/a1bf8ce/src/pb.rs:334:68

error: aborting due to previous error

Upgrading PBR to the latest version fixes the problem entirely. I don't know Rust well enough to contribute a proper fix, but fiddling with the PBR version and regenerating the Cargo.lock file made the compilation process succeed without any problems, and the tool works as expected.
