BEFORE & AFTER · 10.88-SECOND EXCERPT
Hear what +6 dB and +12 dB actually do
These WAVs were exported by Bass Boost from the same original. Switch versions at the same point, with your listening volume kept low. Compare the balance between the bass, kick and voice.
+6 dB bassWAV export · overall level reduced 5.2 dB
+12 dB bassWAV export · overall level reduced 10.8 dB
0:00 / 0:00
A stronger setting can sound quieter. This excerpt needed 5.2 dB of overall level reduction at +6 dB, and 10.8 dB at +12 dB. The low end is stronger relative to the rest; the whole track is not simply louder.
No extra loudness matching or post-processing is applied to these exports. Peak headroom cannot repair distortion already in the source. This is one short example, not a quality score or a promise for every song.

How to use bass boost
02
Adjust and apply
Set the boost between 0 and 12 dB, then select Apply bass boost. The tool applies a low-shelf EQ at 150 Hz and reduces the overall output level when needed to leave sample peak headroom.
03
Compare and download
Listen to the original and boosted previews. If the mix becomes muddy, lower the boost and apply again. Download the result as a 44.1 kHz, 16-bit WAV before clearing the file or leaving the page.
Turn an MP3 into a bass-boosted WAV
Choose a local MP3, adjust the bass and download the processed WAV. The boost changes the low-frequency balance, while WAV is the output format. Renaming a file or converting its format alone does not add bass.
What goes in and what comes out
Use a browser-decodable MP3, WAV, FLAC, M4A or OGG, up to 3 minutes and 25 MB. The download is a 44.1 kHz, 16-bit WAV. MP3 output and YouTube or Spotify link conversion are not available. A WAV made from an MP3 can be larger without restoring lost audio detail.
Keep the bass boost in your download
Select Apply bass boost after changing the setting, compare the rendered result with the original, then download that result before leaving the page. The EQ is applied to the exported audio; it is not just a playback setting for this browser.
Make the result work for your music
Bass boost changes the whole mix
Low-frequency EQ can lift kick drums, bass instruments and low notes together. It does not identify or isolate the bass guitar. Choose the bass extractor when you want a separate bass part, or bass remover for a practice backing track.
Listen for balance
Start with a small increase and compare a busy passage. More low end can cover up a voice or make the kick and bass harder to distinguish. The effect depends on your recording and playback system; a larger number is not always a better result.
Understand the exported level
Boosting low frequencies raises sample peaks. When needed, this tool lowers the entire rendered track by one shared amount to preserve the stereo balance and keep exported samples below full scale. This can make the result quieter overall, while bass remains stronger relative to the rest.
A FEW THINGS TO KNOW
Bass Boost: FAQ
Is this bass booster free?
Yes. You can apply bass boost and download the WAV without an account, payment or separation allowance. Processing runs in your browser. Longer or larger recordings need a shorter excerpt for this tool’s 3-minute and 25 MB limits.
Does my audio leave my device?
No. Reading, EQ, preview and WAV encoding happen locally. Audio, filenames and boost settings are not sent to our servers. Optional usage measurement counts fixed actions such as preparing a result or requesting a download. Clear the file or leave the page to release the local previews.
Will bass boost make the song louder or remove distortion?
It makes low frequencies stronger relative to the rest of the mix. Automatic output level reduction may make the overall file quieter to leave peak headroom. It cannot repair distortion already in your source, recreate missing bass or guarantee clean playback on every speaker.
Can I download an MP3 or process a streaming link?
This tool accepts local audio files and exports a 44.1 kHz, 16-bit WAV. MP3 export and streaming-link import are not available. Exporting a compressed source as WAV does not restore lost detail or make it the original lossless recording.
Is bass boost the same as bass extraction?
No. Bass boost adjusts low frequencies across the full recording using EQ. Bass extraction estimates a separate musical bass part using AI separation. Use the bass extractor for an isolated Bass WAV, or the bass remover for a backing mix without that part.
