One recording. A more focused listen.
Audio tools for the sound you need.
Choose the task that matches your recording. Saturalabs uses a text description to separate one audible source from its surrounding mix, giving you two audio tracks to compare.
Keep a voice or instrument
Describe the wanted source. Listen to Isolated sound for that part and compare it with the original.
Reduce a specific distraction
Describe the unwanted source. Listen to Background audio for the remaining recording and check what survived.

Voice & video
Keep spoken dialogue, work with video soundtracks, or attempt to extract a specific effect. Video inputs produce separated audio for your editor.
Voice Isolator
Separate a speaking voice from a mixed recording using a simple text description. For interviews, podcasts, and voiceovers where the conversation matters more than the sound around it.
Isolate Voice from Video
Pull spoken dialogue out of a video’s soundtrack. Describe the voice you want, audition the separated audio, and bring the result back into your video editor.
Remove Background Noise from Video
Give dialogue more space in a noisy video recording. Choose whether to keep the voice or separate a particular distraction, then review the audio before finishing your video edit.
Sound Effect Extractor
Describe an audible effect inside a recording and try separating it from the surrounding scene. For closer listening and sound design work with recordings you are allowed to use.
Remove Music from Video
Separate a video's music bed from the rest of its soundtrack. Review the remaining dialogue and scene sound, then bring the selected audio back to your editing timeline.
Music & instruments
Study a performance or create a reduced practice mix. Choose one audible source per pass and review both the isolated and remaining tracks.
Drum Extractor
Separate a drum part from a mixed recording for closer listening or practice. Keep the drums, or keep the rest of the song and play the part yourself.
Bass Extractor
Bring a bass part out of a finished mix. Study the notes and phrasing, or use the remaining audio as a backing track for your own bass performance.
Guitar Isolator
Focus on a guitar performance inside a mixed song. Describe its sound, compare the separation, and use the isolated or remaining track for closer listening and practice.
Piano Extractor
Try separating a piano performance from vocals and other instruments. Keep the piano for focused listening, or keep the remaining mix to practice your own accompaniment.
Vocal Remover
Separate the singing from a song to try making an instrumental backing. Use a text prompt, compare both tracks, and keep the version that suits your practice or edit.
Stem Splitter
Separate a described vocal or instrument from a mixed recording. Saturalabs works on one requested source per pass, giving you that source and the remaining audio to compare.
Karaoke Maker
Try turning a song you have into an instrumental practice backing. Separate the singing, keep the remaining music, and check the arrangement before rehearsing your own performance.
Acapella Extractor
Try separating a vocal performance from its instrumental backing. Keep the requested voice for focused listening, phrasing practice, or an edit of material you are allowed to use.
Specific distractions
When one unwanted sound stands out, try naming it as the target. Keep Background audio for the remaining mix and check that the wanted sound survived.
Remove Background Music from Audio
Work with an audio recording where music competes with spoken content. Separate the music bed or focus on the voice, depending on which parts of the recording you need to preserve.
Remove Keyboard Noise
Try reducing typing clicks in a recorded tutorial, voiceover, or meeting. Choose whether to separate the keyboard itself or bring the speaking voice forward, then check the words that overlap each click.
Remove Wind Noise from Video
Try bringing speech forward in an outdoor video with audible wind. Listen carefully to what was captured: wind around the scene and wind hitting the microphone can need different expectations.
Remove Traffic Noise from Video
Try separating nearby road noise from a recorded scene. Choose a traffic-targeted remainder when the environment matters, or a voice-focused output when the spoken message is your priority.
Remove Dog Barking from Audio
Try reducing barking in a recorded conversation, tutorial, or voiceover. Target the barking and review the remaining mix, or focus directly on the speaker when only the voice is needed.
Audio isolation or noise reduction?
Use the cleanup chooser to find a starting workflow for a fan, music, typing, traffic, pauses, or damaged audio.
Learn to write an audio isolation prompt
Choose a source, describe what you hear, and know which output to keep.
