BatchTrimmer is a freeware desktop application for Windows that allows batch processing of audio files.
It is designed to streamline repetitive editing tasks and provide a simple, efficient workflow.
Remove the stills at the beginning and end of your recordings. You can fix the clicks that occur at the cut points with fade-in and fade-out, and you can normalize the recordings in the same editing step.
Thanks to its wide range of target values for Bit-depth and Sample-Rate down to 8 bit and 4 kHz, BatchTrimmer is also very well suited to quickly converting many files into a characteristic, retro-like "LOFI-sound".
The application is a one-file .exe file. No installation is required and the program can be run from any media.
