Body frequency band, 900 Hz
A band-pass filter centred at 900 Hz covers the midrange body, including vocal tone and guitar fundamentals.
High frequency band, 2800 Hz
A high-pass filter at 2800 Hz keeps top-end brightness, cymbal sizzle and attack.
Original for comparison

A frequency band splitter in your browser
This frequency band splitter filters a stereo file into three overlapping bands and keeps the original mix for comparison.
The frequency band splitter gives you four tracks: low (low-pass at 180 Hz), body (band-pass centred at 900 Hz), high (high-pass at 2800 Hz) and the original. It applies ordinary digital filters, not neural separation, so it does not isolate vocals, drums or bass.
Bands overlap, so they will not sum back to the original exactly. Each track downloads as its own WAV.
Frequency band splitter or stem separation
Filtering a mix and separating its instruments are different jobs.
| Need | Good fit | Limits | Use full software when |
|---|---|---|---|
| Layering a sample | Makes low, body and high bands. | Fixed filters; bands do not sum back transparently. | You need adjustable crossovers. |
| Isolating vocals, drums or bass | Filters by range only, so it is not source separation. | Cannot extract an instrument from a mix. | You need AI stem separation. |
| Exporting separate layers | Downloads each track as an uncompressed WAV. | Files download one by one, with no ZIP. | You need bulk or project-folder exports. |
The frequency band splitter processes everything in your browser.
How a frequency band splitter works
A frequency band splitter divides audio into ranges with standard filters rather than AI: low-pass at 180 Hz, band-pass centred at 900 Hz and high-pass at 2800 Hz, next to the original. The filters target ranges, not sources, so they cannot isolate vocals, drums or bass.
Instruments cover wide, overlapping ranges, so one instrument often shows up in several bands. Everything runs in browser memory.
Use the frequency band splitter for listening and sound design
The frequency band splitter suits creative sampling, sound design and reference listening, not vocal isolation or precision mastering. Your audio is never uploaded; you are responsible for holding the rights to it.

Open Frequency Band SplitterFrequency Band Splitter FAQ
Does the frequency band splitter isolate vocals or instruments?
No. The frequency band splitter is a filter, not an AI stem separator, and cannot make acapella or karaoke tracks. For vocals, drums and bass, use AI Stem Splitter.
What tracks does the frequency band splitter produce?
Four: low under 180 Hz, body centred at 900 Hz, high above 2800 Hz and the original audio. Each track can be played and downloaded as WAV.
Do I need an account or plugins?
No. The frequency band splitter runs in a modern browser. Nothing needs installing and no account is required.
Which files does the frequency band splitter accept?
WAV, MP3, FLAC and AAC files, for example, up to 50 MB and from 1 second to 10 minutes long, as long as your browser can decode them.
Why do I hear one sound in more than one track?
The filters overlap, and real instruments and voices share harmonics, so energy from one source appears in several bands.
