About the Compressor
A compressor turns the loud parts down so you can bring the whole thing up — voices become clearer and more consistent.
How to use it
- Drop an audio file (MP3, WAV, M4A, OGG, FLAC) or a video into the box.
- Pick a preset or adjust the controls — amount and ratio. Hit play to hear it live and use “Compare” to hear the original.
- Download as MP3 or WAV. Nothing is uploaded: the processing runs on your device.
Questions
Which preset for talking?
“Podcast” or “Vocal”. Use “Gentle” for music you only want to glue together.
