How to Check Separated Instrument Stems for Practice with LA Studio
Use LA Studio's free Standard six-stem separation to isolate an instrument, then verify the guitar output and remaining stems for leakage before muting tracks in your DAW.
Standard six-stem separation in LA Studio estimates vocals, drums, bass, guitar, piano, and other parts from a mixed recording. The outputs are estimates, not an original multitrack session, and instruments may leak into stems where they were absent.

Run Standard separation and preview each stem
Test a short file first, especially on mobile. Desktop Chrome or Edge gives the most consistent results because available features depend on GPU, memory, and browser.
- Choose your audio file in Stem Separation and run Standard six-stem processing. Standard runs in your browser and is free with no signup required.
- Listen to each part alone in the result panel, then listen to the combination you need. An isolated stem can sound imperfect yet still be useful in context.
- Use Download to save each needed stem as WAV. Align all files at the same start position in your DAW. Do not trim silence from stems individually, as that makes later alignment harder.
- Mute the part you want to practice. Also mute the original recording track; otherwise its copy of the missing instrument will still play through.
Check the existing guitar example to understand what to listen for
The site's teaching example is a 15-second mix of a separately recorded CC0 acoustic guitar and a separately recorded vocal, separated in Standard mode on September 11. The guitar WAV is the actual browser download; the non-guitar comparison sums the other five saved stems at unchanged gain.
This example is not a recording of six real instruments played together and is not a universal quality benchmark. Instrument labels do not guarantee that all of that instrument's audio is confined to its stem.
- Listen to the guitar output stem alone and check whether guitar tone is clearly present without obvious artifacts from other instruments.
- Listen to the five-part comparison WAV and check whether audible guitar remains in those tracks. Guitar may persist in other stems even when the guitar track is muted.
- Compare both solo parts and combinations with the original mix to judge leakage and missing content before you commit to practicing against these stems.
Understand leakage and choose a practical response
Distorted guitars and synths share spectral characteristics, so some guitar content may be assigned to the Other stem. Muting Other to remove residual guitar can also remove sounds you intended to keep.
For rehearsal, reducing the level of an interfering part is often more practical than pursuing complete removal. Use the solo and combination checks above to decide which stems to mute or attenuate.
When Standard mode is not enough
HQ Vocal Separation is a separate two-stem cloud feature that sends audio to a server and has its own usage conditions. It produces vocals and accompaniment only, not six individual instrument outputs, and is not a substitute for Standard six-stem separation.

Limits and checks
Standard six-stem separation is free and runs in the browser. HQ Vocal Separation and other cloud or generation features have separate plan or credit conditions; check the price shown before running.
Audio can appear in a stem even when that instrument was not present in the original recording. A filename alone does not confirm successful isolation; always listen to the stem and check the other outputs for leakage.
The guitar teaching example was processed in Chrome on September 11 and does not establish accuracy on all music. Available features depend on GPU, memory, and browser; test with a short file first.
