Checking your runs
Your file is processed on a cloud GPU by our processing partner and deleted there within 24 hours. We keep the results for 24 hours, keyed by the file's checksum, so a repeat in that time is free.
MP4 and MOV work too: only the sound is sent, the picture stays on your device.
How it works
- What it does
- Takes the wind instruments out of a song, woodwinds like flute, clarinet, oboe and saxophone and brass like horn and trumpet, and gives you them as a second file.
- Model
- A model that knows 53 instruments runs on our own cloud GPU and finds the instrument in one pass; the instrument and the rest add back up to your original exactly, as 32-bit float so nothing is clipped. Measured on recordings with known parts (SDR): violin 0.9 to 7.6 dB (4.0 on average), string instruments with guitars and bass 10.8 dB on average, winds 10.6 dB on average (5.9 to 8.6 with the room's sound). Model names and licences
- Measured
- Measured on 9 recordings with known parts, in two separate tests: the winds came out at 5.9 to 19.3 dB SDR, 10.6 dB on average. The figures above 10 dB all come from dry studio recordings; orchestra and folk recordings with the room's sound measured 5.9 to 8.6 dB. The mix itself, offered as the winds, scores -3.2 to +7.4 dB. A saxophone counts as a wind and comes out with them. On 7 songs without winds, what it took out sat 29 dB or more under the song.
- Output
- Both files are 32-bit float WAV at your file's sample rate. A loud song's instrument or rest can peak above full scale; float keeps those peaks instead of clipping them, so the two add back up to your original exactly. Turn a file down before you export it as 16- or 24-bit.

A song without its winds
Woodwinds and brass together
Flutes, oboes, clarinets, bassoons, saxophones, horns and trumpets come out together. On 9 recordings with known parts the winds measured 5.9 to 19.3 dB SDR. The higher figures come from dry studio recordings; orchestra and folk recordings with the room's sound measured 5.9 to 8.6 dB. The wind instrument remover treats woodwinds and brass as a group, including flutes, clarinets, saxophones, horns and trumpets. Use it for a backing with less wind-section material or for hearing that family more clearly. It does not create a separate file for every player in a concert band or orchestra.
Leaves other songs alone
On seven songs without winds, what it took out sat 29 dB or more under the song, so a band without a horn section comes back nearly as it went in. A recording without wind instruments should change little, but a quiet extracted file is not proof that no wind player was present. A subtle part may be missed or sit below another instrument. Compare the original arrangement and the result before drawing conclusions about which instruments were used in the session.
Nothing thrown away
You get the song without winds and the winds on their own, both as 32-bit float WAV. Nothing is clipped, and the two add back up to your original exactly. Both the winds and remaining music are retained as floating-point WAV files for listening and editing. Dry studio material tends to separate more clearly than a reverberant ensemble recording. A useful practice backing may still contain traces of a horn line, and an isolated winds file may include room sound shared with other players.
Who takes the winds out
Wind players
Practise your part with the orchestra or the band, without the recorded one. A wind player can practise an ensemble part with less of the original section masking the new performance. Check whether removing the whole wind family also removes another cue you rely on. The backing preserves the recorded timing, so an orchestral rubato passage will still require musical following rather than metronomic counting.
Teachers and ensembles
A rehearsal track with the winds taken out, or the winds alone to learn a passage. A teacher or ensemble leader can use the wind file to discuss entrances, balance and articulation, then return to the backing for practice. The model groups related sounds and does not label individual parts. Verify an ambiguous line with the original recording or score before assigning it to a particular player.
Producers
Take a horn section or a sax line out of a track, or keep it for a remix. A producer can study a saxophone or horn-section texture in relation to the rhythm section. Because the output groups winds, several instruments can remain together in that file. If the goal is removing only one saxophone while leaving trumpets untouched, this grouped wind removal is not that level of source control.
How to remove wind instruments from a song
Drop the file
WAV, MP3, FLAC, M4A or a video. Files up to 10 minutes, 25 on Pro. Choose a representative section that actually contains the wind part you need. An introduction without the horns cannot tell you much about the chorus split. Use a clean source, confirm the duration limit, and avoid adding heavy treble processing in an attempt to make a flute or trumpet easier for the model to hear.
Wait about a minute
A 4-minute song takes about a minute, plus up to a minute when the model has to start. The same file again comes back at once. Wait for the complementary outputs, then compare a clear wind entrance with a busy ensemble passage. Listen for sustained notes remaining in the backing and for non-wind material in the extracted part. Long reverb and blended orchestral textures can make the boundary less clean than a close-miked studio horn recording.
Compare and download
Switch between Before and After on one playhead; the winds are marked on the Before picture. Download the song without winds, the winds, or both. Save both versions and keep them at their original start position when editing. For rehearsal, check the backing on the speaker or headphones you will use while playing. For an exposed sample, inspect the entire wind phrase and tail; a short clean attack does not establish that the whole performance is isolated.
Questions about removing winds
Will some winds stay in the song?
A little can. On orchestra and folk recordings with the room's sound the winds measured 5.9 to 8.6 dB SDR, the lowest a folk tune with a flute, fiddle and guitar. Dry studio recordings measured 6.9 to 19.3 dB. Choose an exposed wind entrance and a dense passage when evaluating the result. Dry solo-like phrases and a reverberant full ensemble may behave differently within the same recording, so one clean bar is not enough evidence for a whole song.
Does it take out the saxophone?
Yes, a saxophone counts as a wind and comes out with the others. On one jazz track the winds file held the same part, at the same level, as the model's own saxophone part, and on a second jazz recording it took the alto saxophone. Neither had known parts, so there is no score for the saxophone. The grouping does not create independent saxophone, flute and brass controls. If more than one wind instrument is playing, they can remain together in the output even when one of them dominates the melody.
What happens to my file?
The audio is sent to cloud processing infrastructure, including Replicate, rather than being separated wholly on your device. Results may be held temporarily to serve downloads and identical cached requests. Save the output you need and consult the Privacy Policy for current retention and handling details; this result page should not be treated as long-term storage. Keep both outputs and the original under clear names for rehearsal or editing. Download the files while available and use a separate delivery copy if another application needs a different format or lower playback level.
What should I check after using this wind instrument remover workflow?
Listen to woodwinds and brass and music without the wind section, rather than judging just one file. The difficult cases include shared room sound, quiet winds and overlap with other ensemble instruments. Compare an exposed passage, a busy section and the tail of a sustained sound at the same musical moment. A result can work for practice while being too rough for an isolated production use. Choose based on the sound you will actually deliver, and keep the original nearby when a note, word or effect is uncertain.
What source recording should I use?
Start with the cleanest version you already have and avoid repeated lossy conversions. Saving a damaged recording as WAV does not restore the detail it lost. Excessive EQ, clipping or added reverb before separation can make the task harder. Keep the original and work on a copy so later comparisons remain meaningful. A saxophone counts as a wind instrument in this workflow, despite its brass body. A trumpet and a flute also belong to the selected group. If a reference contains several of these instruments, expect a shared wind file rather than a labelled solo, section and woodwind set ready for independent mixing.
How do file length, plan access and cloud runs work?
Targeted separation allows up to 10 minutes without a paid plan and 25 minutes on Pro; the chosen mode and uploader show the applicable limit. The current catalog allows 3 runs daily anonymously, 10 monthly for signed-in free users, 80 monthly on Pro and 150 on Pro+. Each new file and processing configuration uses the relevant allowance; an identical result can be free while cached. Check the current pricing and the uploader before processing a batch. Downloads are part of the result, not a separate per-file unlock.
Is this separation performed entirely on my device?
No. This is cloud separation: audio is uploaded for processing on external infrastructure. Browser playback, comparison and some exports happen locally after the results arrive, which does not make the separation itself offline. Check the Privacy Policy before submitting sensitive material, and use an appropriate local workflow if audio must stay entirely on your device. Download useful outputs while available; temporary results and cached repeats are not a permanent archive.
Can I publish or share the separated result?
Separation changes the balance of a recording, not its ownership or the permissions attached to it. Use material you own or are otherwise entitled to adapt, and arrange the permissions needed for your intended publication. A separated result does not include a licence to a commercial song, performance or soundtrack. For your own project, keep the source, an untouched separation and a separate delivery copy. Listen again in the complete mix before sharing; an acceptable rehearsal reference may reveal artefacts when exposed alone.
