Set the boostThe pink curve shows how much each frequency is lifted. 6 dB is a clear change; above 10 dB the sound can become boomy.
DownloadDownload the result as MP3 or WAV.

Boosting the bass makes the track louder and can distort it. If that happens, the tool lowers the volume of the final file just enough to avoid it and tells you by how much. The preview is a little quieter than the original for the same reason. Small speakers cannot play deep bass, so check the result with headphones. For more control over every frequency, use the Equalizer.
