StereoMonoizer is a streamlined audio preparation tool designed for both Mac and PC users. It simplifies the process of analyzing audio files by identifying their stereo content and converting them into the correct format before importing into your digital audio workstation (DAW). This application significantly reduces the time required to prepare sessions, making it an invaluable asset for mix engineers, producers, and artists who work with a variety of audio files. Tasks that previously consumed an hour or more per track can now be completed within minutes, enhancing workflow efficiency.

The intuitive drag-and-drop interface allows for quick file import, while its advanced analysis identifies mono audio embedded within stereo files and converts them into true mono channels. It accurately detects mono sounds in different stereo contexts, including partially or fully panned tracks, ensuring the correct output channel selection. The tool also supports conversion between split stereo files and standard interleaved stereo formats. A unique stereo waveform display visually represents the stereo content across the entire file, with mono signals shown in grey and stereo segments in blue, offering users immediate insight into the audio structure.

StereoMonoizer offers flexible control with options to manually override automatic decisions, allowing users to tailor outputs to specific needs, such as separating stereo tracks into individual mono files. Additional features include pan depth compensation to maintain consistent levels after conversion, normalization to adjust file gain, and automatic detection of blank files to prevent workflow interruptions. Multiple output modes provide options to overwrite originals, create backups, or specify output locations, accommodating various project management preferences. These capabilities collectively make StereoMonoizer an essential tool for optimizing audio file preparation.
