Frequently Asked Questions
- How much bass boost should I use?
- 6 dB is a noticeable lift, 12 dB is a strong club-style boost, 20 dB and more is the extreme bass-boosted sound heard in meme edits. With the limiter on you can go all the way without clipping; the track just gets more compressed.
- Why does the whole track get quieter at high boosts?
- The limiter holds the peaks under full scale, so when the bass swells the rest is briefly pulled down with it. That is what keeps the sound clean. For a louder result run the file through the Volume Booster afterwards, or turn the limiter off if you want raw clipped bass.
- Which cutoff should I choose?
- 100 Hz is the classic bass-boost cutoff. 60 or 80 Hz lifts only the sub-bass and keeps vocals clean; 150 or 200 Hz makes the whole low end thick and warm — good for thin phone recordings.
- Can I bass boost a video?
- Yes — upload the video and pick an MP4, MKV or MOV output. Only the soundtrack is processed; the picture is copied bit-for-bit.
