FAQ
Which formats do you support?
In: MP3, WAV, FLAC, AAC, M4A, OGG, and audio tracks from video. Out: any of these, plus Opus and HLS audio (.m3u8 + segments).
Can you normalize loudness?
Yes, to EBU R128 / -23 LUFS for broadcast or -14 LUFS for streaming platforms, with a true-peak limit so nothing clips.
Will I get the source code?
The Premium package includes the commented Python/FFmpeg script and a README, so you can run future batches yourself.
