WavFlacTrim 1.0

10 Mar 2023, 12:10

Hello,

"I'm sharing with you a script that uses ffmpeg to trim silence at the beginning and end of a WAV or FLAC file. It also has an option to change the output sample rate and resize the cover art.

There is no loss of quality. I tested it by trimming the same FLAC file 150 times. ffmpeg.exe must be located in the script directory.

Happy trimming :)
